MiniDexed Raspberry Pi IO Board V2 Design

My two MiniDexed PCBs were some of the earliest ones I made and so I've wondered about revisiting them for a while now. This is a respin of the SSD1306 version of the IO board that is, hopefully, slightly nicer to build a case around! Here is the link to the original PCB: MiniDexed Raspberry … Continue reading MiniDexed Raspberry Pi IO Board V2 Design →

Arduino AY-3-8910 Shield Design

Having build my AY-3-8910 Experimenter PCB I thought a slightly simpler format board would be useful, so I've put together an Uno shield-format PCB that can support one or two AY-3-8910 chips.

Arduino SP0256A-AL2 Shield Design

Having spent quite a bit of time with an Arduino hooked up to an SP0256A-AL2 on a solderless breadboard, and now that I've got some ideas for how I want to sort out the clock, I thought it time to create a PCB to save the unreliable wiring getting in the way!

AY-3-8910 Experimenter PCB Design

Following on from my Arduino and AY-3-8910 experiments, one thing I wanted to do was to try to hook up several AY-3-8910 devices and see if I could stack up the polyphony a little. But that is a lot easier without jumper wires, hence this PCB to support some more experiments with an Arduino Nano. … Continue reading AY-3-8910 Experimenter PCB Design →

Simple PWM Filter PCB Design

Having spent a bit of time attempting (although I'm not sure I'm succeeding yet) to understand how to get a useful filter for my Pico Touch Board Audio, I thought it would be useful to have a simple template PCB that could be used for a range of PWM low-pass filtering options. This is my design. … Continue reading Simple PWM Filter PCB Design →
