Hi all
Thanks for having a look.  This instructable is a follow up to my old clap-clap relay driver circuit.  That instructable gives you all that you need to know about how this circuit is built.  I wanted to be able to show off the kit that I made with the custom PCB.

This is the same circuit, only it is easily soldered together on a PCB that created using Eagle.  I hope you enjoy it!  If you want to make your own from scratch, follow the instructable below, and I'll try to answer any questions you may have =)

The instructable that shows you the schematic, program, and parts list is here:

Thanks again for watching!
