  • Doboz VCO340 Build

    Doboz VCO340 Build

    I built a pair of Doboz VCO340 VCOs. These are based around the CEM3340 chip, which was used in Yamaha DX7, Prophet and other famous synths from the 80s. Here are my notes for the build for anyone interested in building these VCOs for themselves. The project comes as two PCBs and an aluminum front…

    The Doboz TSNM MK I is great touch controller you can build DIY. Touch Sensing Note Memory (TSNM) has 12 capacitive touch plates. TSNM can act as a keyboard, arpeggiator, and sequencer. It has a built in quantizer with a 5 octave range, pressure sensitive touch plates, and CV recorder. TSNM is a great module…

  • Befaco A*B+C

    Befaco A*B+C

    Befaco A*B+C is a voltage multiplier and offset, every system should have one of these! This is a great little utility. I put it up there with Maths. It’s a strong recommendation I know. I really feel this module deserves a place in any rack because it could find a place in any patch! What…

  • My battery powered Eurorack

    My battery powered Eurorack

    I wrote previously about being inspired by people using battery powered erorack systems to make electronic music in nature. I tested it out at the Eurorack SF cafe jam meetup. It worked great! If you’re in the bay area join this Meetup! Power supply Most Eurorack modules run on +12 volts, -12 volts, and +5…

  • Arduino FM Synth

    Arduino FM Synth

    I have wanted to get into building things with Arduino for a while. I ran into a project on Instructables.com that looked easy, I thought I’d jump in and give it a try! The project creates a simple synth/sound generator with two oscillators. The oscillators are ring modulated with a frequency control for each. There…

  • Battery powered eurorack

    Battery powered eurorack

    I had seen a lot of really cool eurorack in nature posts. Not sure if these were done live in the moment or put together in post production. The idea of twiddling knobs and making music at the beach or in the park was enticing. Let try and get you in the mood with some…

  • Ugly Face black with dots

    Ugly Face black with dots

    I did another Ugly Face. This time on a black gloss enclosure with milled dot pattern. Milling this design took over an hour. These enclosures are not flat on top! Some of the dots on the upper right did not get milled. I had to pull those out of the original SVG image, make a…
