Previously I've explored the potent anti-hypertensive effect of dietary flaxseed in hypertensive patients. This was a double-blind or randomized placebo-controlled trial where they disguised ground flaxseed in baked goods versus like flax-free placebo muffins and got an extraordinary drop in high blood pressures. As you can imagine, the flaxseed industry was overjoyed, praising the impressive findings as was I. After all, high blood pressure is the single largest risk factor for death on the planet Earth. Yes, we give people medications, lots and lots of medications, but most people don't take them, as in 9 out of 10 people take less than 80% of their prescribed blood pressure pills, just 8%. It's not difficult to understand why patients are asked to follow an inconvenient, potentially costly regimen, which will likely have detrimental effect on their health-related quality of life, to treat it mostly asymptomatic condition, so they may feel worse instead of better due to the side effects. The answer then is to give them more drugs to counteract the effects of the first drugs, like giving men Viagra to counter the erectile dysfunction caused by their blood pressure pills. How about using a dietary strategy instead, especially if it can just be as effective? And indeed, the drop in blood pressures they got in the flax seed study was greater than the average decreased observed with a standard dose of anti-hypertensive drugs. And flax seeds are cheaper, too, compared to even single medications that most patients are on multiple drugs, and has good side effects beyond their anti-hypertensive actions, but not all good. Taking tablespoons of flax seed a day is a lot of fiber for people who have been living off of cheeseburgers and milkshakes their whole lives, and can take a little while for your gut bacteria to adjust to the new bounty. So, people who start out with low-fiber diets may want to take it slow at first. Not all studies have shown significant blood pressure lowering effects. There have been over a dozen trials by now, involving more than a thousand subjects, and though yes, put them all together, and overall there were significant reductions in both cystoc and diastolic blood pressures, the upper and lower numbers. Following supplementation with various flax seed products, none were as dramatic as that six-month trial. The longer trials tended to show better results, and some of the trials just used flax seed oil, or some kind of flax seed extract. And the thought is that the whole is greater than the sum of its parts. Each of the components of interest within flax seed, the omega-3s, the cancer-fighting lignans, all the soluble fiber and plant proteins all contribute toward the blood pressure reduction. Okay, but how? Why? What's the mechanism? Some common blood pressure medications, like Norvask or Procardia, work by reducing the ability of the heart to contract, or slowing the heart down. And so it's possible that's how flax seeds work, too. But no, dietary flax seed reduces blood pressure without cardiac involvement, but rather through changes in plasma oxylipins. What are oxylipins? Oxylipins are a group of fatty acid metabolites involved in inflammation, and as a result have been implicated in many pro-inflammatory conditions, including cardiovascular disease and aging. The best characterized oxylipins in relation to cardiovascular disease are derived from the long chain omega-6 fatty acids, known as arachidonic acid found preformed in animal products, particularly chicken and eggs, and can be made inside the body from junky omega-6 rich oils, such as cotton seed oil. But elevated levels of pro-inflammatory oxylipins in older subjects are normalized by flax seed consumption. See, that's how we think flax seed consumption reduces blood pressure in patients with hypertension, by inhibiting the enzyme that makes these pro-inflammatory oxylipins. I'll spare you from the acronym overload, but basically eating flax seeds inhibits the activity of the enzyme that makes these pro-inflammatory oxylipins, leukotoxin diols, which in turn may lower blood pressure. Identifying the molecular mechanisms adds confidence to the antihypertensive actions of dietary flax seed, but that's not all oxylipins do. Oxylipins may play a role in the aging process, but we may be able to beneficially disrupt these biological changes associated with inflammation and aging with nutritional intervention like flax seed. Older adults around age 50 have higher levels of these arachidonic acid-derived oxylipins compared to younger adults around age 20. These elevated concentrations of pro-inflammatory oxylipins in the older age group may help explain the higher levels of inflammation in older versus younger individuals. I mean, as we get older, right we're more likely to be stricken with inflammatory conditions like arthritis. So this elevation of pro-inflammatory oxylipins may predispose individuals to chronic disease conditions. But what if you took these older adults and gave them muffins, ground flax seed-containing muffins? Four weeks later, their levels dropped to here, right? Down to like 20-year-old levels. Demonstrating that a potential therapeutic strategy to correct the deleterious pro-inflammatory oxylipin profile is via dietary supplementation with flax.

It won't cost you a thing but will help me and my channel out tremendously and help me reach my goal of 10,000 subscribers by TFCon in October. Now what I'm looking at in this video is an upgrade set for War for Cybertron Kingdom Ractonite by Firetox Designs to give him a Dino Rider look.  So now let's take a look at this set and get it attached to Kingdom Ractonite. And welcome to Patriot Prime Reviews. The Firetox Dino Rider upgrade set includes five pieces. You have two brackets there on the end, two big cannons and the pilot seat. And the pilot seat is designed to be used with battle masters, the ones that turn into guns. Then we'll go ahead and get him installed in the seat now. What you want to do is take the blaster off the back of your battle master and then right here. The Firetox is really cool with designing this. There is a slot for the battle masters handle to fit in. So just get him in position here, punch that right through that slot. So now you've got your battle master ready to go. Now you'll take the weapon and it plugs into this port right there. How cool is that? I think that is really ingenious. Now what you're going to do is take your brackets right here. Let's get the blasters out of the way for now. And you'll take these brackets and install them on the pilot seat. And you want to make sure you have the angled bracket going back. Now what I would recommend is to glue these once you get them. That way they don't pop off because I've got one that fits a lot tighter than the other. But I haven't glued these yet so I can show that off to you guys. So there is the pilot seat. So put that out of the way. And now we've got the cannons and both of these are the same. Lots of great detail all the way around that Firetox is known for. And what's really cool there is a little spinner here on the back. So these can rotate. I love that. That is sweet. And these are blast effect compatible. So you've got this going on. Terrible sound effect I know. So now get your Ractonite figure. And what we're going to do is you line the brackets up with the ports on Ractonite's side. See if I can do this all on camera this time.  You've got two different looks right here. I like this big drum. So I want my drum on top. So I'm going to get this blaster right here. And you're going to feed it through the hole on the bracket into the side of Ractonite. So we've got that one attached. Let's see. Right here. Line that up. Punch it all the way through. And there we have Ractonite with his Dino Rider upgrade. And I think that looks awesome. Especially with the little cannons up here. It really adds to the figure. And a really cool way to display this guy now. So then of course you can take the blast effects. Plug these into the cannons. And you also have smaller blast effects that will fit into the blaster here on the pilot's seat. And what's cool is this blaster can rotate around. So now you have Ractonite all armed and ready for battle. And this looks fantastic. Fire Tox. You outdid yourself with this one. I love this. This is so cool. Now guys if you want one of these Dino Rider upgrade sets for your Ractonite figure make sure and hit up Fire Tox on his Facebook page that I'm going to put a link to in the description of this video.

A bibliography, a reference page, or work-cited page is usually the last page of your research project and lists all the sources you consulted. If you've entered your sources in Sotero, creating a reference page is pretty easy. If you've ever labored over a long list of sources and scrutinized every period and parentheses, this will probably make you happy. First, select all the sources you want to include in your bibliography. You can do this by holding down the Control button, or Command on a Mac, and clicking on all the ones you want. Then right-click on a highlighted item and select Create Bibliography from Items. If you've already selected your citation style preference, that will be your default. If you haven't, you can select that here from the list. Next, choose if you want the in-text citations or the actual bibliography or work-cited info. Then choose your format. I'm going to copy mine to clipboard so I can paste it at the end of my research project. Select OK, and I'll show you how it turned out. You can also drag and drop from Sotero to create a bibliography. Here's how that works. I've got Sotero on my left and Microsoft Word on my right. And I'll go to one of my subfolders, and I want all three of these sources to be in the reference page in my document. So I'll select all of these by choosing the first one, holding down Shift on my keyboard, and then selecting the last one. And then I'll left-click and hold, and drag those items over to my Microsoft Word document and release the mouse. Now I'm just going to make sure it's double spaced, and that the title is on top of the page.


Hello, and welcome to this presentation of the Reset and Clock Controller, or RCC, for STM32H7, X3, X5, and X7 microcontrollers. The RCC is linked to the Power Controller Block, or PWR. Before going through this slide set, please have a look at the slides concerning the PWR block. The STM32H7, X3, X5, X7 Reset and Clock Controller manages the reset, the system, and peripheral clocks generation. STM32H7, X3, X5, and X7 devices embed four internal oscillators, two oscillators for an external crystal or resonator, and three phase-locked loops, or PLLs. Many peripherals have their own clock, independent of the system clock. The STM32H7, X3, X5, and X7 RCC provides high flexibility in the choice of clock sources, which allows the system designer to meet both power consumption and accuracy requirements. The numerous independent peripheral clocks allow a designer to adjust the system power consumption without impacting the communication baud rates, and also to keep certain peripherals active in low power mode. Safe and flexible reset management without any need for external components reduces application costs. The RCC manages several types of resets, the power reset, the system reset, D1 and D2 domain reset, the local resets, and the backup domain reset. Thanks to the voltage monitoring function included in the PWR block, the filters embedded in the NRST pad and the RCC reset control, the amount of external components is reduced to a single external capacitor connected on the NRST pin. The first type of reset is the system reset, which resets all the registers except certain registers for the reset and clock controller and power controller. It also does not reset the backup domain. Many sources can generate a system reset. An invalid voltage on the VDD or VCOR supply, CPWR block for details. An invalid function on VDD due to the brownout function. The brownout function allows the user to choose their own threshold levels for the VDD supply, CPWR block for details. An exit from standby mode, a low level on the NRST pad, a timeout from one of the independent watchdogs or IWDG 2-1, a timeout from one of the window watchdogs if allowed by the reset scope bits, WW2-1 RSC. Software reset request initiated by the Cortex M7 named CPU-1 or Cortex M4 named CPU-2. A low power mode security reset, which is generated when stop or standby mode is entered, but is prohibited by the option byte configuration. Note as well that a system reset asserts the NRST pad, which can be used to reset external components on the board. The reset source flag can be found in the RCC control and status register. The power-on reset is generated when the VDD or VCOR voltages are lower than a certain voltage threshold. The backup domain reset occurs when the BD-RST bit in the RCC-BDCR register is set to 1 by the application, as shown in the figure. When the VDD and VBAT are powered on if both supplies have previously been powered off. A D1 or D2 domain reset occurs when one of the two domains has been switched off. In addition, the peripherals have individual reset control bits. It is also possible to reset the CPU-1 and its associated window watchdog WWDG1 or RSTC1 and to reset the CPU-2 and its associated window watchdog WWDG2 or RSTC2. The power-on reset is the reset having the largest coverage. The power-on reset resets all the logic located in the VDD and VCOR domains, except those in the backup domain powered by VBAT, which contains the RTC and the external low-speed oscillator. Note that the power-on reset also triggers the system reset, so the NRST pad is asserted during a power-on reset. The system reset resets most of the logic located in the VDD and VCOR domains, except certain resources located in the RCC and PWR blocks. The backup domain is not affected by this reset. The backup domain reset resets the backup domain powered by VBAT, which contains the RTC and the external low-speed oscillator. The domain reset resets the complete D1 and D2 domains when the corresponding power switch is activated. The hold-boot function can be used to set one of the two processors to hold after a system reset or an exit from standby mode. This function can be useful if one processor has to boot in advance, for example, to perform the system initialization. Note that when one of the processors is in hold, it does not prevent the system from entering standby mode. The RCC offers a large choice of clock sources, which can be selected depending on low power, accuracy, and performance requirements. STM32H7X3X5 and X7 device embeds four internal RC oscillators. A high-speed internal RC oscillator, or HSI, which can work at 64, 32, 16, or 8 MHz. A low-power internal RC oscillator, or CSI, working at 4 MHz. An accurate RC oscillator working at 48 MHz. And a low-speed internal 32 KHz RC oscillator, or LSI. STM32H7X3X5 and X7 devices embed two oscillators for use with an external crystal or resonator. A high-speed external 4-48 MHz oscillator, or HSE, with a clock security system. And a low-speed external 32.768 KHz oscillator, or LSE, also with a clock security system. The STM32H7X3X5 and X7 device also embeds three phase-locked loops, each with three independent outputs for clocking different peripherals at different frequencies. The high-speed internal oscillator, or HSI, is a 64 MHz RC oscillator, which provides fast wake-up times. The HSI is trimmed during production testing, and can also be user-trimmed. A dedicated divider can generate a 32, 16, or 8 MHz clock. The HSI can be selected as a clock at wake-up from system stop. And as the backup clock if an HSE failure is detected by the clock security system. The HSI can remain powered when the system goes to stop mode in order to speed up the wake-up time. Certain peripherals, such as the I2C's and USART-LPUART, can request the activation of the HSI in system stop mode in order to generate wake-up events. The HSI is enabled by the peripheral only for the wake-up sequence detection, and remains disabled outside of this wake-up sequence. The low-power internal oscillator, or CSI, is a 4 MHz RC oscillator, which provides fast wake-up times. The CSI is trimmed during production testing, and can also be user-trimmed. The CSI can be selected as a clock at wake-up from system stop. The CSI can remain powered when the system goes to stop mode in order to speed up the wake-up time. Certain peripherals, such as the I2C's and USART-LPUART, can request activation of the CSI in system stop mode in order to generate wake-up events. The CSI is enabled by the peripheral only for the wake-up sequence detection, and remains disabled outside of this wake-up sequence. The high-speed external oscillator, or HSE, provides a safe crystal oscillator system clock. The HSE supports a 4 to 48 MHz external crystal or ceramic resonator, and also an external source in bypass mode. A clock security system automatically detects an HSE failure. When detected, a non-mascable interrupt is generated, and a break input can be sent to timers in order to put critical applications such as motor control in a safe state. When an HSE failure is detected, the system clock is automatically switched to HSI, so the application software does not stop in case of a crystal oscillator failure. STM32H7X3X5 and X7 devices embed an ultra-low-power 32 kHz RC oscillator, or LSI, which is available in all modes except VBAT mode. The LSI can be used to clock the RTC, UARTs, the low-power timers, and the independent watchdogs. The accuracy of the LSI is plus or minus 1.8%. The LSI consumption is typically 130 nanoamps. The 32.768 kHz low-speed external oscillator, or LSE, can be used with an external crystal oscillator, or resonator, or with an external clock source in bypass mode. The oscillator driving capability is programmable. Four modes are available, from ultra-low-power mode with a consumption of only 290 nanoamps to high-driving mode. A clock security system monitors the failure of the LSE oscillator. In case of failure, the application can switch from the RTC clock to the LSI clock. The clock security system is functional in all modes except VBAT mode. It is also functional under reset. The LSE can be used to clock the RTC, the use-arts, or low-power UART peripherals, and the low-power timers. The PLLs embedded in STM32H7X3X5 and X7 devices provides a flexible way to generate the required frequency for the system or peripheral clocks. They offer a wide input frequency range from 1 to 16 MHz. If the input frequency is between 1 and 2 MHz, then the user has to select the VCOL path. If the input frequency is between 2 and 16 MHz, then the user has to select the VCOH path. The two VCOs also have a smart frequency range, 150 to 420 MHz for VCOL and 192 to 836 MHz for VCOH. The PLLs also provide three different outputs, which are all derived from the VCO output via post dividers, DIVP, DIVQ, and DIVR. In addition, it is possible to change the values of the post divider without disabling the PLLs. The application just needs to disable the corresponding post divider, change the division ratio, and re-enable the post divider. In order to get a duty cycle close to 50%, the application has to program the post dividers to even values. In addition, the PLLs can be switched to fractional mode, allowing a high precision in the VCO frequency. The 13-bit fractional divider can be changed without disabling the PLLs. This feature can be used to perform accurate clock drift compensation. The PLLs share the same clock source, HSI, CSI, or HSE. Each PLL has a dedicated pre-divider in order to adjust the reference clock for each PLL. PLL 2 and PLL 3 are dedicated to the generation of the kernel clocks for the peripherals. Certain peripherals, such as the SAI, USB, etc., may require a specific frequency. The PLL 1P output is used as system clock for processors and buses. The PLL 1R is dedicated for the debug trace, and the PLL 1Q is also used as kernel clock for peripherals. Note that the PLL's clock source cannot be changed if one of the PLLs is enabled. The system clock can be derived from the HSI, CSI, HSE, or the output of DIVP of PLL 1. The switch used to select the system clock is dynamic, meaning that it is possible to change the frequency on the fly without generating timing violations. In addition, all the pre-scalers presented in the figure are dynamic, so they can be changed on the fly as well, making the frequency scaling operation very simple. The clock of the CPU 1 does not exceed 480 MHz. The AHB clocks do not exceed 240 MHz, as well as the CPU 2 speed. The APB clocks do not exceed 120 MHz. Note that HR TIM and certain timers can use clock frequencies up to 480 MHz. The clock for the RTC AWU can be selected from among LSE, LSI, or HSE divided. Note that when HSE divided is used as a kernel clock for the RTC AWU, the frequency cannot exceed 1 MHz. Note as well that if LSI is used as a kernel clock for the RTC AWU, the RTC AWU will no longer be clocked if the VDD and V-Core supply are removed. If HSE divided is used as a kernel clock for the RTC AWU, the RTC AWU will no longer be clocked if the system goes to stop mode or if the V-Core supply is removed. The LSE can remain enabled in all low power modes and in V-Bat mode. The RCC also provides two clock output signals, MC01 and MC02. A pre-scaler allows the application to adapt the frequency to the pad's capability. Many STM32H7, X3, X5 and X7 peripherals have different clocks for the data and control streams via the processor bus interface, as well as the clock for the specific peripheral interface. Generally, the clocks for the data and control streams via the processor bus interface are named bus clocks, and the clocks for the peripheral specific interface are named kernel clocks. The peripheral clocks represent the clocks received by the peripheral, bus clocks and kernel clocks. Having a separate bus clock and kernel clock allows the application to change the interconnect and processor working frequency without affecting the peripheral. For certain peripherals, it is also possible to disable the bus clock as long as the peripheral does not need to transfer data to the system. So, it gives a good flexibility on the frequency selection for the bus processor and memories and the real need of the peripheral interface. For example, the UARTs have a kernel clock which is used, among other things, by the baud rate generator for the serial interface communication and an APB clock for the register interface. In addition, certain peripherals are able to request the kernel clock when they detect specific events. The distribution of the kernel clocks is not detailed in this presentation. Please refer to the reference manual for specific details. Most of the peripherals receiving a kernel clock have a dynamic clock switch to select the optimal clock source. The proposed clock sources generally come from one of the seven PLL outputs dedicated to the kernel clock generation. Internal or external oscillators. This is mandatory for peripherals needing a kernel clock when the system is in stop mode. Pads, for example, on peripherals using an external PHY, but also for audio as well, in order to use a clock reference from an external device. And other internal peripherals for synchronization between blocks. The dynamic switching facilitates the transition from one source to another. RCC registers are used to configure the kernel clocks for all the peripherals. Peripherals generally receive one or several bus clocks and one or several kernel clocks. Each processor can control the clock gating of the peripheral clocks via dedicated registers located in the RCC. The gating of the peripheral clocks depends on several parameters. The clock-enabled bits. Each processor has a dedicated control bit for that, named C1, PERXEN, and C2, PERXEN for simplification. The low-power clock-enabled bits. The processor states C-run, C-sleep, or C-stop. And the autonomous bits for peripherals located in the D3 domain. Setting the bit C1, PERXEN to 1 indicates that the peripheral PERX is enabled for the CPU-1. Setting the bit C2, PERXEN to 1 indicates that the peripheral PERX is enabled for CPU-2. This operation is named allocating a peripheral. It is important to note that the RCC offers two register sets, allowing each processor to enable or allocate peripherals. The peripheral allocation informs the RCC that the CPU-1 or CPU-2 are enabled by a peripheral. This information is used by the RCC for the clock control in low-power modes. So before using a peripheral, the CPUs have to allocate it. The same peripheral can be allocated by both processors. It is up to the application to avoid resource conflicts. Certain peripherals are implicitly allocated to a specific processor. The flash, access RAM, ITCM, DTCM-1 and DTCM-2 are implicitly allocated or enabled for CPU-1. CPU-2 can allocate any of them, but by default they are not allocated to CPU-2. The D2 SRAM-1, D2 SRAM-2 and D2 SRAM-3 are implicitly allocated or enabled for CPU-2. CPU-1 can allocate any of them, but by default they are not allocated to CPU-1. Certain other peripherals are allocated to both processors. This is the case for IWDG-1, IWDG-2, RCC, PWR, EXTI and D3 SRAM-4. When a CPU allocates a peripheral, this peripheral is linked to the processor state for the low-power modes. The CPU plus the peripherals allocated by this CPU and the associated interconnect is considered by the RCC as a CPU subsystem. The D1 and D2 domain core voltages can be switched off. To give a simple example of how the RCC uses the peripheral allocation, we can state that the RCC will not allow a domain to be switched off if one of the peripherals of this domain is used by the processor of the other domain which is not switched off. The following table gives a simplified view of the system states versus domain states. A domain is in D-run mode when its bus matrix is clocked. Its bus matrix will be clocked if a CPU which is in C-run, C-sleep mode allocated a peripheral on this domain. A domain is in D-stop mode when its bus matrix is no longer clocked. The CPU of this domain is in C-stop mode. The other CPU is not allocating peripherals on this domain or the CPU is also in C-stop mode. A domain is in D-standby mode when its V-core supply is switched off. Note that it is possible to keep only the D3 domain in D-run mode while other domains are in D-standby mode. For more details on system states, please refer to the PWR training slides. Note that when the system resets, for example after a system reset, the HSI is selected as the system and peripheral clock. The CSI, HSI 48 and HSE are off as well as the PLLs. The LSI is still working if it was previously enabled. After a system stop the PLLs are switched off. The application can choose either the HSI or CSI as the system clock and peripheral clock. The HSI 48 and HSE are off. After a D1 or D2 domain exits D-stop or C-stop mode, the RCC maintains the same clock setting as the one used before going to low power mode. C-sleep mode does not affect the clock settings, but only acts on the clock gating. The autonomous mode offers the capability of providing peripheral clocks to peripherals located in D3. Even if the CPU to which they are allocated is in C-stop mode, and if both D1 and D2 domains are in D-stop or D-standby mode. The gating of the clocks of peripherals in autonomous mode depends on the mode of the D3 domain. If the D3 domain is in D-run mode, the peripheral will receive its peripheral clocks. If the D3 domain is in D-stop mode, the peripheral clocks are gated, but the peripherals can still request the kernel clock if they have this capability. The autonomous mode does not prevent the D3 domain from entering D-stop or D-standby mode. The D3 domain is able to switch alternatively from D-run to D-stop mode and then from D-stop to D-run mode according to peripheral activity. For example, if the system is expecting messages via I2C4, the complete system can be put in stop mode. When the I2C4 detects a start bit, then it will generate a kernel clock request. This request enables the HSI or CSI, and a kernel clock is provided only to the requester. Then the I2C4 can decode the incoming message. Several cases may occur. If the device address of the incoming message does not match, then the I2C4 releases its kernel clock request until a new start condition is detected. If the device address of the incoming message matches, the message has to be stored in the D3 local memory. The I2C4 is able to generate a wake-up event on a dress match in order to switch the D3 domain to D-run mode. When the D3 domain is in D-run mode, the bus interface clock is activated, allowing the I2C4 to transfer the message into memory via DMA1. If the D3 local memory is not full, then the D3 domain will go back to D-stop mode without any CPU activation. If the D3 local memory is full, the DMA1 can generate a wake-up event in order to activate CPU1 or CPU2. Please refer to the D3 domain low power slide set for details. Certain peripherals such as the UARTs and I2Cs are able to asynchronously detect events requesting a kernel clock for the processing. The RCC can provide on-demand a kernel clock to those peripherals. With a CPU allocating the peripheral is in C-stop mode or if the system is in stop mode. The kernel clock request will work if the selected kernel clock is HSI or CSI. In order to speed up the activation time, the HSI or CSI can be maintained activated during system stop mode. In system stop mode, the LSI and LSE clocks are still available for peripherals. A kernel clock is provided to the peripherals located in D1 or D2 domains if one of the following conditions is met. When the CPU to which the peripheral is allocated is in C-run mode and if its enable bit is set to 1. 2. When the CPU to which the peripheral is allocated is in C-sleep mode and if its LP-enable bit is set to 1. 3. When the CPU to which the peripheral is allocated is in C-stop mode and if its LP-enabled bit is set to 1 and the peripheral is generating a kernel clock request and the kernel clock source is HSI or CSI. And 4, when the CPU to which the peripheral is allocated is in C stop mode and if its LP-enabled bit is set to 1 and the kernel clock source is LSE or LSI. The bus interface clock will be provided to the peripherals only when conditions 1 or 2 are met. A kernel clock is provided to the peripherals PERX of the D3 domain if one of the following conditions is met. 1. When the CPU to which the peripheral is allocated is in C run mode and if its enable bit is set to 1. 2. When the CPU to which the peripheral is allocated is in C sleep mode and PERX LPEN equals 1. 3. When the CPU to which the peripheral is allocated is in C stop mode and the D3 domain is in D run and if its LP enable bit is set to 1. 4. When the CPU to which the peripheral is allocated is in C stop mode and the D3 domain is in D stop and if its LP enable bit is set to 1 and the peripheral is generating a kernel clock request and the kernel clock source is HSI or LSI. Or 5. When the CPU to which the peripheral is allocated is in C stop mode and the D3 domain is in D stop mode and if its LP enable bit is set to 1. Of the peripheral is LSE or LSI. The bus interface clock will be provided to the peripherals only when conditions 1 2 or 3 are met. This slide list the RCC interrupts the LSE and HSE clock security systems the PLL ready and all six oscillator ready signals can generate and interrupt. In addition to this training you may find the power control and interrupt controller training is useful.


Let's dive deeper into the UX design process and see how it all comes together. The UX design process can be broken down into several stages. The first stage is research. This is where designers like Jane gather information about the users and their needs. This can be done through different methods, such as user interviews, surveys, and usability testing. Designers talk to real users during user interviews and ask them about their goals and pain points. This information is then used to create user personas and fictional characters that represent the different types of users. User personas are then used to guide the design process and make sure that the final product meets the needs of the users. The next stage is information architecture. This is where the designer starts to think about how the information will be organized. They create site maps and wireframes to show the structure and layout of the product. Wireframes are basic visual representations of a website or an app, and they use to communicate the design to other members of the team and stakeholders. The next stage is interaction design. This is where the designer starts to create user flows and journeys that guide users through the website or the app. They create interactive prototypes that simulate the final product and then test them with the users in order to gather feedback. User testing is an essential part of the interaction design stage. It allows designers to see how users interact with the product and identify any issues that need to be addressed. The next stage is visual design. This is where the designer creates the look and feel of the product. They choose colors, typography, and imagery to create a consistent and visually appealing user experience. The final stage is accessibility and inclusive design. This is where the designer ensures that the product is usable by a diverse range of users. They follow accessibility guidelines and best practices to ensure that the product is really inclusive. The result is a website or an app that is easy and enjoyable, making users more likely to return and complete their intended task. Keep in mind that the UX design process is iterative. Designers may go back and forth between stages to make changes and improvements. This process ensures that the final product meets the user's needs and goals and creates a positive experience for them. Now that you understand the UX design process, it's time to get to know the wider design team. Get ready to learn about the different roles of UX designers, UI designers, and UX researchers, and how they work together to create exceptional user experiences.


Live from San Jose, California, in the heart of Silicon Valley. It's theCUBE, covering QuickBooks Connect 2016. Now, here are your hosts, Jeff Frick and John Wall. I hope you're ready for high energy. I think we have high energy for you here. Welcome back inside San Jose, the convention center here, along with Jeff Frick. I'm John Walls, we're here on theCUBE and bringing you live streaming coverage throughout the day here at QuickBooks Connect 2016. I talked about energy, our next guest came up to us. We didn't have met and all of a sudden started a high five and everybody on the crew and said, we are ready to rock this place. So I guess we are. Don Brolin, who is the founder and the CEO of Powerful Accounting, a Connecticut-based accounting firm now joins us. And Don, are you ready to rock this place? I'm ready to crush this. We're going to hammer this right out. No question. We're going to teach. All right, tell us a little bit about your firm. So you started as a one-person shop, a solopreneur, and now you've evolved to where you've got, I believe you said seven people working for you, three of those in a virtual environment. So tell us about all that, about that growth and about the challenges of having that virtual office set up for three of your key employees. Well, it's been easy. No, I'm just kidding. Yeah, so we've been growing and growing and really starting to laser focus on our practice. And so we do provide bookkeeping services, tax return services, the basic accounting firm that does all those kind of things. What we're really passionate about is IRS representation and helping civil or criminal cases, helping them get out of that, hopefully keeping them in a civil environment. But it has been tough. We've had policies and procedures. We've had to create transparency, virtual people where you have to make sure they can still be part of your team, even though they're not in your office. And so that's been a really big focus for us is to continue our, we are team Brolin. That's how we roll, Brolin with Brolin, right? So we love it. And we really try to have that team atmosphere. I don't call them employees. I call them my team members because they truly are my team. And they're like family. And I think that's one of the things with our core values is that we've really tried to define who we really are as a firm. And that has revolutionized our practice because we really know who we are. And I think everyone needs to do that. So is there a moment where you redefined and decided we're going to be something specific versus just kind of general purpose accounting? And if so, what was the catalyst for that? So interestingly enough, I had built a relationship with a law firm, Green and Sklars. They're in Connecticut. And they're just, they're my boys, I call them, but they're great people. And they're passionate about helping their clients get out of the issues that they're in. And so he and I just kind of, Eric Green and I just kind of formed a great friendship. And he said, you know, will you do all of our accounting for our clients when we have cases come in? I have had experience testifying in court. Unfortunately on that one, I was on the IRS's side, which is good, because you know why? Here's the secret about that. Now I know what they look for because I'm watching them build a case against somebody and helping them build a case. So I know what they're looking for. I know what they know and what they don't know. So that's fun. Jeff, I want to talk to you later, by the way.  We go in hot, you know what I mean? Down on her elbow. Yeah, we're totally coming in hot. It's awesome. So that became just a passion, right? So one of our core values is passionate, be passionate and we're passionate about our clients. I'm passionate about my team succeeding as a group. Definitely our clients are just so important to us. But what about the virtual environment, though?  You know, they like to know who's doing what, especially when you're working with numbers and clients want to work with people face to face. So how have you been able to bridge that or maybe allay those concerns to the point that you can have success? Yeah, you know, it's really, obviously the technology is just everywhere, right?  So if we're going over a P&L, we may do a go-to meeting, but we're still seeing each other. And it's as if we meet together in person all the time. The technology's allowed us to do that. Of course, cloud technology, QBO is, you know, we don't have to be on their machine or like the date back of the day when we had to log on to their machine and take it over. Like that's just so ridiculous. Please don't do that. So that's a great recommendation for people. So we take clients who are willing to accept how we work with them. And we want to make sure that it's personal because it really means a lot to us to help them grow. I mean, that's what we're here for. We're not here to book entries anymore. It's a whole different ballgame now with technology. And have you changed kind of your building relationship? We've heard about that. You know, to get away from the hours-based building to a retainer or some other kind of mechanisms that define your building relationship with your clients. We have a great client onboarding process. And we defined it because I said, you know what, I love clients. And they're obviously, we don't make money without them, right? Yeah, you wouldn't have much of a business. It'd be kind of boring, I think. Well, I don't know. We have a basketball court right outside our office. We would just do that. Very profitable. It would, exactly. So one of our processes, we teach them how we work. So they may not be totally familiar with all the technologies that we use, but from the first call that comes in, they understand that we're going to exchange an engagement letter. We're going to exchange a payment authorization form. You're going to pay a deposit upfront. And that's going to happen through our document management system right from the beginning. So we don't exchange paper with them. It's all done electronically. Right signature. Right from the beginning. Right from the beginning, we teach them. This is how we exchange information together. And they get it or they don't. Most of the time, they do. People are pretty good. Nobody with a flip phone, we won't take clients who have a flip phone. Who they have to have a smart phone. But anyway, so we kind of vet through that process. And I loved your question about the billing. So with the bookkeeping, it's easy to do value billing, right? Because as you're getting better, you're making more money because you're not billing by the hour. With the IRS representation work, we bill by the hour. Because those cases, you don't know what's going to happen. It's a real important niche area that even bookkeepers, accountants, CPAs, EAs, anybody can get involved in that kind of work. It's a huge market out there. The attorneys don't want to do that. They're tax attorneys, you know? They want to do their law part. So they're looking for more people like us. And that relationship's been, I'm just so blessed with that relationship. And do you need an attorney just legally to get involved in that process? They need somebody that's past the bar to represent them? Or not necessarily? They don't necessarily. So a lot of the times we'll come in and we deal with the agents 100%. So we're on the POA with the attorney. We're under likely a covel letter, which means the IRS can't bring us to court if it's a criminal case because we're protected by that relationship with the attorney because we're not natively. So that process that we go through, we handle the agents a lot of times. And that's a skill to handle an IRS agent. Because if you think about it, they want to get their job done. They have inventory. Inventory to them are these cases. A caseload. So when you are more open with them and overwhelm them with information, they're so much more likely to remove a penalty, an accuracy penalty, a fraud penalty, because you as the accountant are so open with the information. And it's just, it's a relationship that you have to groom them and get to know them. We give them coconut milk.  Right? And that's, I mean, that's how we approach it. So it's obviously better if you don't get in trouble with the IRS in the first place. I'm just curious from your point of view, and there's a lot of tools here represented on the floor beyond just QuickBooks Connect. How do people usually get in trouble? I mean, if you could get ahead of some of your clients that have gotten in trouble, what are the two or three kind of really key things that aren't that complicated that will help them avoid the trouble in the first place? Definitely one thing is documentation. I think with all the apps that we're using out there, it doesn't matter, Expensify, all of those T-sheets, tracking your mileage, mileage tracking, all of those things that most business owners don't want to do. The technology is there, they just don't know it. And so you prepare a tax return, here's one of them. Mileage, you've got to track your mileage.  Okay, so how much of that was, I'm always doing business. No, you're not, okay? You're not always doing business. So you have to really work with your client to say, hey listen, you've got to have documentation. So we work very paranoid. Our firm is, I say we work very paranoid because we see these cases that happen. And they're not necessarily, they're not happening to our clients necessarily, but that documentation, home office deduction. Like these are just standard things where you've got to be careful. Home office deduction, if you're on your kitchen table, that's not a home office, right? Like so people are, I work from home. Okay, well you can't work, I mean, who doesn't work and watch football? We all do, right? But just having that documentation and every solution is here that you need for your business owners. And I always tell them do one at a time. Pick one application, one big pain point, or something you're not tracking now. Receipts, you have to have receipts. I know that sounds crazy. But the IRS will accept an electronic receipt. So it's interesting, I've done some research. They literally will accept whatever the standard of technology or the standard practice of the times, if you will, in the receipt in whatever format. Because it used to be, you have to have all the pieces of paper, but they don't require that anymore. And they're all thermal friends and they don't last for seven years or whatever. And they don't last, absolutely, absolutely. So going from when you start, how long did you start the company? So I've actually had my third rendition. So we don't want to do things once. We want to do them three times. I started my first bookkeeping company in 1999. I had two babies that I love so much. Two babies under two. So I said, oh honey, how about you raise them? I'm going to go start a firm. And so that's when I started and it was just a guy who was actually building an in-law apartment for my parents. And he was like, hey, my bookkeeper isn't, you have an accounting degree, right? Can you do my books? I'm like, okay. And that's literally how it all started. So you've gone from that to when now you have maybe as many as eight now in your firm as of January 1st. The growth pains that you had along the way. Yes. Share those with other small business owners out there about what you've learned. And then maybe from a QuickBooks perspective, those pain points that for you, how they have been solved or how you're addressing them through various QuickBooks services. Sure. And I love that question because every journey is a journey. And I've personally gone through an amazing journey in 16 years and I'm looking forward to the next 16, right? But the pain points for me, one of the biggest pain points for me was running a business and then having, how do you get home and get to your kids and get to your family, right? And your husband and everything. So that was a really big struggle for me because I'm doing the technical work because when I was by myself, I'm doing the billing. I'm billable, I gotta be billable, but they still have to run the company. I have to manage it and administrate it. So when it's just yourself, it's really, really tough and you lose and you sacrifice. And we all know that Michael Phelps talked about that yesterday. I mean, we sacrifice when we build a business. And so you have to accept that. And so the more you can kind of get that support team around you to build a business is really important. And then when you add on, staff is really, it was really where the rubber meets the road.  Into it. Come on, you got it. You got me. I caught it being with that right in there. I was so smooth. I was there. I was there. Cause we're all on the same team. Of course we are, except you like the nationals, but we'll talk about that later, right? We'll get around to that. So we are, we are, we're suffering. So, you know, for me, it was really about how do I gain my life back? So I'm like, okay, I need to, I know I need to hire some people. And I was playing softball, of course, was what else do you do in the outfield with another outfielder? And I was like, hey, what do you do? She's like, I do some bookkeeping for this club. I've been with them for like 15 years, but they're closing the manufacturing plant and moving and whatever. And I'm like, hey, you want to work for me? She's like, sure. And you know, we're running out. And of course I make her run after all the balls. And she was a great, and she was a remote, 100% remote right from my first person. And this was in 2011 when I brought her on. I had a partnership in between that and I learned so much in that partnership and carried that on to, I call the third rendition of now powerful accounting. And I really find that hiring people and making sure you have a lot of transparency, you have to have procedures in place for consistency, policies, and those are so important. And really over the last year is where we've really zeroed in on that because we found that I say one thing and then I expect something different, right? Cause we don't remember half the time what we're talking about, right? So I learned that I had to really structure my company. And in order to grow, I needed to structure it and literally document. And so the applications were kind of for me an easy transition. I'm very open-minded to technology and it's really important. But growing a company is not an easy road. You just have to know and I loved it. You have to sacrifice. It's going to be sacrifice. And then the QuickBooks side of it. So the QuickBooks side, yeah, absolutely. And that transit, I was on the Intuit Accounting Council back in 2008. And because, and the reason why I went is I had met someone who had done a certification in QuickBooks and her name was Leslie Cappacetti. She's one of my favorite QuickBooks pro-advisor people in the world. She's like a mentor to me. And I went up to her and I said, how did you get this training gig? Like, and plus you have a really nice sweater. It says Intuit on it. How do I get one of those? Right? And I just talked to her about it. She said, you got to get on the council, Brolin. Get on the council. And so I did. And then I got on the trainer writer network. And so QuickBooks for me, I've been really part of their team in growing products and working with them in their development. And QuickBooks is just, we don't use any other accounting software. We use QuickBooks. That's it. And you know why? Because we don't have to do anything else.  No, I'm using the best software there is. Why wouldn't, you know, why do I need to go to a different company? And it's been a great relationship. Did you have to fire any clients when you made this move? Unfortunately, we've, it's funny to ask that because so we have a folder structure we use Smart Vault for our document storage. And when a client, either we fire them or they leave, we move them into an old client file folder. And I scroll through it every once in a while. And I'm like, wow, that's a lot of people. I want, am I that bad? You know, and I'm thinking about it, but yeah, so it's tough to fire a client. And we really, if they're not seeing value in us, we say, listen, why don't you, you just want a bookkeeper. You don't want someone who is consulting with you and helping you grow your business. You just want to collect a paycheck every week. And there's nothing wrong with that. But I don't feel like we're giving you enough value. And I take that very personally every single client. I want them to have value. And if they're not seeing it, it's not, it's not healthy for anybody. So last impressions for we have to go. Your thoughts here at the show. I thought we had five hours. We do, but. Okay. I know, I get you. I got it. This is the East Coast feed. That's right. We'll do the Asia Pacific feed later. Later. Impressions of the show. How many years you've been coming? Well, it's only been a couple of years, but kind of what, what does this represent as a support and resource for you trying to grow your business? So I love that you asked that. And the reason for that is I feel like this is like a family reunion for me. I'm very good friends with a lot of the application partners here. And we see each other at conferences. My fellow colleagues that I was either on a council with or we're, you know, on Facebook or doing something. We just really get to see each other and learn. And the speakers are amazing and inspiring. Like we need that refueling. And I remember the first conference that I had, had gone to years ago. And I just was like, wow, if I got out of my office and came to something like this, like there's something bigger than me, right?  But then you come and people are so nice and like friendly and it's a big family reunion here. And, and so honored to be part of any of it, you know? So. Well, you told me that the only thing you use a file cabinet for is to put your t-shirts in. Absolutely. So probably an Excel, Jeff. Yeah, you're probably, yeah, about an Excel. And we actually sell our loot. We sell it and we donate it to a charity. Even better. So one of our staff picks the charity and we just, and we pass it on. Put mine on Jeff's tab. I will, yeah. No, I'll take this credit card when we get off the stage. Don Brolin from Powerful Accounting. Thank you for being with us. Thank you for having me. It was high energy. Hey, we got to do it. We're going to crush it out. We did crush it. It was very good. I appreciate it. Back with more here on theCUBE and San Jose in just a moment. Awesome.


We are talking about radios that you make from scratch, lamps, wooden extensions, power banks, zasimu. From scratch. And where do you actually operate when you do all this? I'm based at Lake Isama, it's besides Kasarani. Initially I used to work from home, but recently because the business is doing well and more people are reaching out to it. So I decided to have a shop just in the nearby place where I stay. So people buy actually these things? Ya sure, people buy. What do they say, they feel from the ground? They are very powerful and durable, so people are switching from the other source of lights to these lamps. Because they are now noting that they are more durable and they are also affordable. And they also come with the warranty. And the warranty is for how long? For 6 months. So how did you come up with this idea in the first place to go and make something out of waste? I started since my childhood in my early teens. They say that the chick that will grow into a hen and this also implies to the one that will grow into a coke. Is seen on the day it hatches. So the day you hatched, you knew your potential? Ya, so in my early teens I started exhibiting characters that were to be recognized little later. Ya, I started doing things that today turned out well today. So my dad used to buy lamps so that we can study. But I was not good in class, so most of my time, I took most of my time opening the lamps wanting to see what is inside. So in the process of opening, I did not have a screwdriver or the required tools for opening. So I used to break, maybe I hit with a stone. So after breaking, after seeing what is inside, to return was a problem. So I used to tie it to the silo tape. And silo tape was also nowhere to be found. I just tied it with a thread or even the mahogany glue. But now these items that you are breaking, what are your father's items, all of them? Ya, my dad used to buy lamps a lot because at rural home there was no electricity. And buying paraffin was also expensive. So that was back then when you were at home? Ya, in class 4, class 5.  Ya, I just came in Nairobi in 2017 to look for green up pastures. Means you grew up from a humble background? From a very humble background at the beginning. So he bought lamps? Ya, he bought lamps. You break them up, you find out what is inside? Ya, in the process of returning back to its original place, you find that it could not come back to its original position. So when dad came back he used to quarrel maybe sometimes. Because the lamps was to be used by the whole family. And you find that one person had destroyed it. So that's a whole kenning that he received? Ya, but eventually, slowly by slowly, he came to realize that this is a talent and potential. Ya, so he also, when he started getting the west, he used to bring it to me. So he embraced your kind of unfamiliar character of breaking items. It became something that he familiarized himself with. So he said that I brought you this one, so don't touch mine. Ya, so just destroyed the one that is already destroyed. Yes, and live along with mine. So growing up, how were you doing in school? Because you said you didn't like much of the books. You preferred going hands on. Your hands of kind of a person? Ya, back in primary, while I was in class 6, I was an altar server. So in a few years to come, I would be ordaining as a priest, but electronics took most of my time. Ah, you used to be at the altar. Is that where you still are? In a few years time you will be ordaining. Ya, I would be ordaining maybe. If I had continued, that is. Oh, ya, if you had continued. Ya, but electronics took most of my time. I could not concentrate in church. So I started most of my time while at home or even at school. I used to come up with the things that took most of my time. Let's take a look at these things. You can describe how each one was made. I don't know how you made it. Are they all made in the same way? Ya, they are all made in the same way, but in different shapes. I think we can light it up. Ya, let's light it up and see. Wow, looks beautiful. So they are all made in the same way? You can give us just a brief overview of these things now. Okay, like this one, it's 90% ewest. The only thing that I bought from a shop is the switchbox. The patrice. Same to this one. This is 100% recycled. This is 100% recycled? Ya. I'm seeing some cables here. Ya, the cable was void and thrown away. So I took the other side. Ya, because the other side used to charge phones, and the other side is inserted in the charger. So how is it powered? It's powered by... Okay, you can charge it using the normal phone charger. So you connect this to a phone charger? Or just in place where they use beacon. So you get an adapter for this? Ya. And also when you charge, you see it lighting here, up here. Ya, there is a signal not for you that it's charging. So when it doesn't charge, it won't light here? Okay. Yes. I wish you had... did you carry a power bank? Ah, no. No? You said you make power banks also. Ya, I make. I wish I could see one. Ya, I make a lot of things. So I just carried this specifically because most of the people buy the lamps. Ya, I make power banks and radios but I only get order from my client. Oh, okay, okay. So it's not like you just make them and display them. It's per order. Ya. All right? Yes. What do people say when they see things like this? Ah, people get happy. Especially your family.  Ya, he's still there. Ya. And when he sees you do great things like this? He's very happy and he wished me all the best. Ya, he's a very prayerful man. Ya, he do pray for me, even my mum. They wish that they predict good on me. Ah. Yes. They support you. They really support you. This is quite good, Patrick. This is quite good. So the expense used to make this isn't that much. You just buy what is inside here. Somehow, what is it called? Electronics. For this lamp? Yes. How are electronics and electricals? What's the difference?  But electricals may be the hardware, the big things like these ones. Okay. Ya. So you only use money to buy the electricals? Yes. Okay, all because like in the slum where I stay, they sell a lot of wind electronics there. Oh, okay, okay. So when it comes to this, somebody can trust that it can last long. How long can this last once it's lit up? It also depends on how you take care of it. Because you can't just mishandle it and you expect it to stay for long. But I try to make something durable so that I can win people's trust. The one that has gone for long, the one that I know has gone up to one and a half years. Yes. So that if you really take care of it, but sometimes they fall? Sometimes also people… Of course, normal day to day running, you know, unagonga meza in anguka chini. Ya, in most cases, you see, you find out that people leave it to their children and children also want to see what is inside. Just like I used to be. Because there is another Patrick somewhere. Ya, there are a lot of Patrick's. You want to break and find out what is inside? Somebody want to break and find out what is inside this? Yes. Okay, okay. So when it comes to the market, how are you marketing yourself so that this can go outside there? This kind of technology? I use various methods of marketing. Initially I used to work from one person to another. But the first generation lambs, people used to criticize them a lot. Ya, people could laugh and say that I'm doing things that they used to do in early 60s. So that really discouraged me. Ya, that was before COVID-19. You know, people sometimes can be very discouraged. So they told you that whatever you're doing is outdated? Ya. So I should come up with new things that I featured in the 21st century. Wow. Ya. You never gave up? I gave up for a while. You stopped it? Ya. What made you come back and how long was it that you took a step back? I started it in 2018. Ya, as a business. So, due to people criticizing it, I stopped. But during the COVID-19 pandemic, ya, you know, everything was in mess. Ya, nothing was in order. So there was no money, everybody was to fend for himself. So I got a donation from GiveDirectly of 12,000 shillings. That's $20. So I used the money to restart the lamp business. How did they get in touch with you? How did they reach out? Give Directly usually give people money. Ya, poor people money for their personal use. But I used the opportunity to come to restart the business. Because initially the customers whom I had sold the lamps initially were requesting. For more lamps? Ya. The more people criticized it, there are some who had seen the importance of it. Ya, so I chose to go with the people who recognized it. So I decided to continue making. You know, there's one thing that is quite interesting and that many innovators fail to get. Taking advantage of your networks. Taking advantage of the people around you, the customers you have and of course the organizations that are there that offer assistance or support. Ya, you know, most of the people, when people get money, maybe one may be tempted to buy good shoes, expensive clothings and maybe to party. It's not easy to handle money, especially unexpected money. Because I did not expect the funds from Give Directly. So it came abruptly. So I had a lot of options on what I can use the money to do. But by that time, because I had some customers requesting the lamps and also I had always been wanting to restart again the business. Ya, because I liked technology a lot. So I was finding the best thing I can do in technology. But I'm aware that you also work with the kids, children? Yes, yes. I feature the kids. The certain percentage of money I get from sales, I give them. Some are street kids. So you give back to the community? Yes, I give back the community. I give back the light. And also, there are some people that I give light as a grant, as a donation. I just don't sell to everyone. Because maybe there is an old person who is selling, maybe has a small grocery. He doesn't have light. Maybe he just want maybe if we can just get a hundred chillings only. So you see such a person raising the money for lamps. One for lamps is a bit hectic. So there are some factors that I consider before selling. Because the mamambogas need something like this? Yes, because electricity is not everywhere. And also in some areas you see the blackout is frequent. And also in rural areas most of the places doesn't have electricity. What are your target areas, especially in the slum areas? Which particular places do you target when it comes to this as your market? Okay. I target just Kenyans, but specifically people with glossaries. People places with the frequent blackouts. Like which particular slum? Because in Nairobi you have so many slums. In Korogocho and Ngomongo? Ngomongo and Korogocho. Yes. And even in Kayole I have sold some most.  Yes. So when I give away for free you tell that person the lamp costs this amount. So you will find out that another person comes. So he brings you the person by referral. He says that somebody saw your lamp and he is interested. So he links me up with the person and I sell the lamp. So now most of the time people just call me bring me another lamp. Because when a person buys the first lamp there is high probability that he will buy the second, third even the fourth. And if he doesn't buy he will bring me another custom. So they often recommend. Yes. And that's what I was saying earlier. Sometimes we fail to take advantage of the customers we have. You know, marketing ourselves. Ninauza he tell a friend, tell a friend, tell a friend. Yeah customers really play an important role in marketing. Because they can recommend you or even not recommend you. For example if the lamp was not good or durable. They could say that maybe this lamp, if you could get another alternative just go with it. Because the lamps are not good. But you see they promote me. They spread good gospel. They say the lamp is good so you can buy it. Wow. Yeah so they play an important role. Very very important. Yes. I don't know if you had those photos that I received. If they are ready we can declare a few of them. Faith. If they are maybe you can let me know. Are they ready? No. Amakuna. Those particular photos. Alright. Let me show you. I hope they are ready. Because I wanted you to comment on those particular pictures that you had sent earlier. But as we come to a close. What are some of those things that you've seen in terms of that particular experience that have really inspired you to want to do more especially in this area, in this industry? I've been inspired by a lot of things. First of all the customers. When a customer buys the lamp he recommends it positively. He tells me to keep it up. And also most of the people wish that they had the talent I have. So I see that if someone else is wishing the thing I have. So I should work on it thoroughly. Also I have some good friends that support me. After I give directly posting my story. I have friends across the world. You post your stories? They posted my story on LinkedIn. Your friends posted your story. We need such kind of friends. Everybody needs such kind of friends. They are very supportive. And that's why you also got to be known by other people beyond where you are. Thank you so much for coming Patrick. I wish you the best. Thank you. Keep doing what you're doing. I love this. I think everybody needs lamps like this. Especially this one. It's quite small and I love how it looks. It's durable and portable. We can just carry it along. We can carry it anywhere. Especially the ladies when you have bags. Instead of carrying that iron box. Thank you so much for coming. I appreciate it. Thank you for having me. Of course that brings us to the end of this particular conversation on lambs from EU waste. Of course we are with Patrick here. An inventor and innovator giving us his thoughts in regards to this particular issue. So I hope you've learnt something. Keep talking to us. The hashtag is why in the morning. We want to make sure Patrick will be back in a bit. And of course my name is Ram Magukko. Thank you so much for being part of this conversation. We still have more coming up here. We are right here on why in the morning.
