Step 1: Tools
solder (60/40 or 63/37... not the lead-free silver solder)
flux (this is more or less a must-have to get good connection to pcb traces)
30 AWG wrapping wire
wire wrap tool (Optional, but makes things easier)
wire stripper (A razorblade works well on wrapping wire, but check out my instructional on "precision wire stripper" to see the one I use in this tutorial.
A DIP microcontroller
A small tactile switch
