Euro-G1: Testing the DSP G1 Eurorack Synthesizer
The DSP-G1 by DSP Synthesizers is an 8-pin Arm M0+ 32-bit microcontroller containing an analog-modelling synthesizer complete with LFO, 24db filter, VCA, and envelopes. The VCO mixes between three waveforms and has a nice detune for a very Roland Juno-ish sound. With the help of an Arduino Nano the idea for a DSP G1 Eurorack…

Here’s a quick and relatively simple method for finishing aluminum Eurorack panels with a scouring pad (and help from a cheap palm sander), then sealing with acrylic. Perfect…
Stomper Eurorack Drum Module
The Hammer of God tabletop drum module is now a Eurorack drum module. All inputs can be CV controlled (0-5V), including the built-in clock-divider. It uses standard 10 pin +12/-12 power, drawing a paltry 30mA. It’s triggered by sync-24 clock, trigger/gate, or button press. It has a handy gate output to easily (and accurately) apply…

Hammer of God Aggressive Drum Module
Sure, you can get a nice aggressive kick drum by distorting a sample or analog kick until it’s just a square wave. Why not just start with a square wave? Filtering? Nah, the speakers will handle that — and the blood pooling in your ears will take care of the rest. If you used Master…
