I made some ugly face PCBs back in 2009 and had a couple left over. I built this up when I first got the mill.
The Ugly Face is a DIY classic invented byTim Escobedo way back in the early mid 2000s if I recall. It’s a unique circuit with a surprising sound if you haven’t built this you should give it a try.
Check my OSH Park projects I have a great board for this project the builds easily and works well.
