DIY Vactrols

WORK IN PROGRESS The vactrol is a slightly unusual but very useful component for analog music synths. There now follows a bit of background then the (very easy) construction instructions. Then a bit of experimentation/testing. I’m hoping the testbed circuit below, after another revision or two, will be suitable for using as a sub-block of one or more synth modules....

ADHD and the Dreamachine

In the Guardian/Observer today was an article Bright sparks: could bioelectricity make us smarter and healthier? This mentions the use of transcranial direct current stimulation (tDCS) “… to improve everything from treatment-resistant depression to poor maths skills”. The piece lacks links but I was intrigued enough to find a few, along with a potential application for my Dreamachine project. This is...

Dreamachine #4 : Squeeze!

Documentation Home GitHub Repository Dreamachine #1 : Background Dreamachine #2 : Pink Noise Dreamachine #3 : Progress I’ve put together a second prototype. I wanted something more solid as well as a checking it would be repeatable, sanity check kind of thing. The software isn’t finished, but I’ve done the harder bits (concurrency hell!). But it basically works! On Amazon...

Dreamachine #3 : Progress

Documentation Home GitHub Repository Dreamachine #1 : Background Dreamachine #2 : Pink Noise Dreamachine #4 : Squeeze! Let me get one thing out of the way first. Arguably this thing is massively overengineered for a flashy-lights thing. What it will actually do is given in Requirements (that and the rest of the documentation is still in-progress). Chatting with my brother...

Dreamachine #2 : Pink Noise

Documentation Home GitHub Repository Dreamachine #1 : Background Dreamachine #3 : Progress Dreamachine #4 : Squeeze! I’ve made quite a lot of progress with Dreamachine, more on that soon. I’m pausing to jot notes because of something I was just trying is quite interesting while implementing a DSP Pink Noise Generator. As well as the flashing lights, I also want...

Dreamachine #1 : Background

Documentation Home GitHub Repository Dreamachine #2 : Pink Noise Dreamachine #3 : Progress Dreamachine #4 : Squeeze! I wrote this as a brain dump a couple of weeks ago, I’ve made a lot of progress since. Latest status can be found on GitHub. A few months ago, along with other fun bits, a friend sent me an ESP32 module. It’s...

Amplifier/Attenuator Synth Module

My first attempt at a homemade Eurorack-compatible module. A continuation of My First Homemade Synth Module! in which I describe some the motivation and circuit design of this module : KiCAD schematic & front panel templates are on GitHub. To recap, my main motivation was to bridge between the different signal levels I encounter in my music room. So I...

My First Homemade Synth Module!

My first attempt at a homemade Eurorack-compatible module. This is part 1 of 2, next is : Amplifier/Attenuator Synth Module KiCAD schematic & front panel templates are on GitHub. So I recently got a Eurorack frame and one commercially-made module (see My First Modular Synth!). Coincident with this a Behringer Wasp synth arrived. It very soon became apparent there where...

Cheap Laptop Upgrade

Upgrading memory & hard drive in an Asus F507M laptop (with mostly-broken keyboard). A €300-ish machine made significantly more friendly with €70 of parts and a couple of hours work (mostly research). Some tips if you want to do something similar. Caveat: I use Ubuntu, no idea what might be different on other operating systems. Background A few years back...
