This is a very simple VCF with a CV input. It is from Hendrik Göttling's schematic "Ultra Simple VCF." I don't remember where I found the schemat...

This is a popular synth made from an Arduino microcontroller. It's so easy to make it feels like cheating. To make your own, get yourself an Ardu...

This is my 4040 synth module. I'd like to thank Wrongbot for the inspiration (see his "Chessboard dual 4093 + 4040 synth" video). The 4040 works ...

Super easy to build Tremolo Pedal, sounds better in real life. TRUST ME! The basic idea is to have a flashing led point at a Photoresistor in you...

This is a Drone 40106 Synth with three square wave oscillators. I used a 4584 chip which is the same as a 40106 chip, but if I said "4584 Synth," ...

These are some of my homemade circuits in action. The 4017 sequencer (based on the Baby 10 circuit) sends voltages to the 4093 Synth, which then g...

This is based on the 4017 Baby 10 Sequencer. It has 8 or 6 steps, variable rate control, pitch control for each step, switches to turn each step o...

This is the first circuit I've ever built. It was fun to do. I used Mr Mimm's basic APC design and then turned it into a theremin by connecting a...

This is my first circuit bending project. Got the keyboard at the SE Portland Goodwill Bins for a couple bucks, and invested another $8 at radiosh...
