Circuit for battery operated micro-soldering iron.
hi, i want to make a micro soldering iron that can run on AA batteries.i have a micro soldering iron, but it runs on 12vDC@2A. it requires an adapter.so i want to make one that runs on AA batteries heats up quick, and uses less power.i saw many products but want to build one myself. An appropriate circuit will be great help. Thanks in advance,
