    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…

    Doboz TSNM MK II

    I decided to build the new version of the Doboz TSNM, the MK II. Just received it in the mail the other day. There are two versions of this. One is surface mount and the other is through hole. Touch Sensing Not Memory (TSNM) is a touch controller for modular synths. It has many modes…

    Doboz TSNM MK I

    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 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…

    Doboz VCO340

    The Doboz VCO340 is a DIY VCO built around the CEM3340. This is a VCO on a chip that was used in many famous synthesizers back in the 80s. Here’s what the Electric Druid has to say: The 3340 is the oscillator chip found in many of the famous polysynths of the analog era; the…

    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…

  • Weston Audio AD110

    Weston Audio AD110

    I built this as a DIY project. They offer it assembled also. It’s a Eurorack adaptation of the drum sounds from the Boss DR-110. All the sounds are analog, not samples. The project comes as three PCBs and a front panel. It’s all through hole parts. The parts are fairly easy to get. I few…

  • Serge Resonant EQ

    Serge Resonant EQ

    This is the last piece of musical gear for the year. It’s a fixed filter bank with 10 filters. 8 of the filters are bandpass filters. The highest and lowest bands are high pass and low pass filters. It’s like a 10 band equalizer with synth filters. The filters are tuned to major sevenths and…

  • Thonk

    I have been planning to work on some Eurorack projects. Turns out it’s hard to find the correct jacks, or at least the PCB mount variety. I got a few on Aliexpress to experiment with I’ll talk about these in a future post. Turns out Thonk has the jacks I’m looking for. I had to…
