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...

One Minute Singles

tl;dr – embrace the format I’m of a generation where singles were very important. As a kid, a piece of music on 7″ of vinyl lasting about 3-ish minutes, and then later the 12″ extended single took over. But clearly the duration of a piece of music bears no relation to it’s aesthetic value. I have, in a long past...

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...

Rattus Pigmentus

There must be a better title for this, but is too weird/gross/funny to hold back until I think of one. This : Some months ago I had a rodent problem. Well, it had been a problem on and off for a few years, started when my neighbour used my chicken shed for a while (for chickens). The rats loved it,...

ECG Module

Mari mentioned the other day she was looking at portable electrocardiograms (she’s a medic). I remembered I’d impulse-bought an ECG module from Banggood a while back, about €10, epidemic paranoia presumably. Hadn’t got around to playing with it. I’m thinking, add whatever’s necessary to hook it up to a phone, use an oscilloscope app (plenty available, I’ve used one called...
