Turn an ordinary clicking pen into a solder dispenser, a bit of solder comes out with every click. This takes advantage of the pen's mechanism which actually spins. You can still use the pen as a pen.
Inspired by the simpler (and in a way, better) pen dispenser in the Guide to Field Soldering instructable.
Step 1: Parts and Tools
