2007 Controller

Here is the 2007 controller. TinCanTools.com hammer board can be seen on the right. Just below that is the AC wave zero crossing curcuit. Everything to the left is 75HC595s driving ULN2803A transistor arrays.

 

The board was home etched (more on etching later), and that is why it is single sided with the strip board style wiring (green wires).

 

Above the bug board (only half visible) is the power supply board taking 5V in and giving 5V and 3.3V out.
