Circuits listed below are in PDF format
I have about 1000 circuits in a binder I started in 1982, most of them culled from magazines and books and most of them hand-drawn! The circuits below were drawn using Protel Schematic and are just a sampling of what's available and what I've done. (I've built hundreds of circuits.) Later, when I have the time and web space, I'll consider scanning my 4" binder and putting those circuits here, maybe even with a printed circuit board layout.
Check out the links below this table for access to thousands of circuits.
| Standard for my Christmas displays. This one used solid-state relays | |
| I needed a drum, so I made one using an IC that I recorded the sound on. I had to make a PC board for the amplification of the sound IC | |
| They wouldn't give me a schematic, so I reverse-engineered the board. | |
| Named for Darth Vader, not sure if he used a 16 channel sequencer or not... | |
| Same robot I built the drum for. This is the entire electronic section | |
