Developing on STM32

Posted on May 8, 2020

Over the past months I’ve been investigating moving away from Teensy to another microcontroller  ecosystem. I love Teensy, and I wouldn’t have made the majority of my projects without it, I’ve learnt so much from it, and I still think it has the best libraries of any of the alternatives. It’s always the first thing […]

Looper Version 1 Complete

Posted on July 11, 2019

If you’ve been paying attention to this site, you’ll have seen I’ve been working on a eurorack looper for sometime. The first version of this is now done. You can find the source code here.     What is it? A looper module in the eurorack format inspired by the MLR app which ran with […]

Case and new module finished

Posted on May 16, 2019

Nothing is more motivating than an imminent deadline, and my gig in Berlin served as a good end point to get my new case finished, and a brand new module into it. The case was built out of a Habitat trunk, see more details here. I’m pretty pleased with how it turned out. It’s nice […]

Fun with audio codecs

Posted on April 14, 2019

For the past few months (yes, it’s a slow process), I’ve been working on a new version of my Teensy based eurorack boards. Whereas my previous boards have used either the Teensy’s built-in ADC and DAC, or the PJRC audio shield, this one uses a separate chip, known as an audio codec, called the WM8731, […]

Piano Music

Posted on September 27, 2018

In the run up to Electromagnetic Field Festival which I played earlier in the year, I was preparing for a performance using only instruments and effects I’d built myself, either from kits or of my own design. The problem was, most of my modules are effects, they transform sound, but they can’t really generate sound […]

The Teensy Trio

Posted on June 21, 2018

I’ve now built up 3 modules based on my Teensy eurorack board. It was recently discovered that the Teensy 3.5 actually has 256k ram (I think previously it was stated as having 192k?). The latest version of Teensyduino (1.42) unlocks this, so the 3.5 will probably be my goto Teensy board for the near future, […]

Redux the redux

Posted on June 12, 2018

I’ve had a couple of interesting comments on my AudioFreeze/Glitch Delay module which have contributed to revising the PCB, details of which can be found here. Why is it so big? Good question! The original AudioFreeze is pretty wide, and that’s because the PCB itself is pretty much that wide. I set out to create […]

Glitch Delay – How it works part 1

Posted on February 11, 2018

The Glitch Delay is the Teensy based eurorack Delay module I designed that you can read more about here. The video shows what it sounds like, but I thought I’d go into some more detail about how it actually works, and how I went about designing it. The Hardware The brain of the module is […]

DIY Sriracha Eurorack Case

Posted on November 27, 2017

This weekend I built a DIY Euroack case out of a cheap tin lunchbox from eBay. I want this case to house some of my Teensy based modules and form an all-in-one guitar focused effects box. The project was reasonably straightforward. I used one of these power boards which supplies +12v/-12V from a 14-24V DC power supply. […]

MIDI Mustard

Posted on February 27, 2017

For my gig at Thee Sunday Sonics this weekend I decided to make a new USB controller. I was previously using one with many more buttons and knobs than I actually needed. For this project I used the Teensy LC. A low cost version of the Teensy (around £10). It has less memory and computation […]
