Simple Square Wave Oscillator PCB Design

I've now done several posts inspired by the Oskitone Poly 555, and I do plan to build one myself one day (I can't get a kit as they don't deliver to the UK, but I've had a PCB manufactured - watch this space!). This PCB is essentially the oscillator part of the Poly 555 in … Continue reading Simple Square Wave Oscillator PCB Design →

Atari Punk Console PCB Design

The Atari Punk Console is a bit of a "Hello World" build for DIY analog synthesizer fans. I looked up the circuit and read a little about how they work for my 556 Timer Light Theremin project I found on ebay, but the main background can be found in the following: Atari Punk Console on sdiy … Continue reading Atari Punk Console PCB Design →

Arduino Top Octave Generator – Counter Experiments

After building my Arduino Top Octave Generator I went off an ordered some binary counter devices to use to produce some "lower octaves". This is a test run project to explore how the 74HC393N devices I have work. In part 2 I start to explore how to expand this to multiple keys and octaves. https://youtu.be/MO8jG0fjUSU Warning! … Continue reading Arduino Top Octave Generator – Counter Experiments →

556 Timer Light Theremin

I found this "Atari Punk Light Theremin" circuit which uses a 556 timer chip but haven't been able to find out much about it on the Internet ... at least under that name... But I did find quite a lot about the "Atari Punk Console" which appears to have taken on an Internet life of … Continue reading 556 Timer Light Theremin →
