Let's Make Robots!  Temperature Controller for my soldering iron
Soldering Iron Temperature Controller  vishurockssrivastava's
picture  After buying a crap soldering iron, I found that its
not good enough to solder even the most basic of things. I have
a $30 gift coupon in RobotShop thanks to jorgen and I thought of
using it to buy a new iron for me. Ideally, I want to buy
something like this but my budget is limited, so limited that I
can't buy it.
