SMTtimer

This is what happens when you let an engineer overcomplicate a problem.  We wanted to give students 5 minutes per step during soldering class.  So?  We made a 5 minute digital timer.  Push the button.  The LED slowly blinks, getting faster and faster, until at 5 minutes, it’s nearly solid.

We no longer have kits, but do have some pre-assembled with battery.
