Mini Listening Post

One of the most fascinating pieces of electronic artwork I've seen is Mark Hansen and Ben Rubin's Listening Post when it was on display at the Science Museum, London. Designed in the early 2000s it was on display from around 2008 for a number of years, but unfortunately it has been packed away in storage … Continue reading Mini Listening Post →

MiniDexed Raspberry Pi IO Board V2 Build Guide

Here are the build notes for my MiniDexed Raspberry Pi IO Board V2 Design. The previous version can be found here: Version 1: MiniDexed Raspberry Pi IO Board. SSD1306 Version: MiniDexed Raspberry Pi IO Board – Part 2 HD44780 Version: MiniDexed Raspberry Pi IO Board – Part 3 Warning! I strongly recommend using old or second hand equipment for … Continue reading MiniDexed Raspberry Pi IO Board V2 Build Guide →

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 and SP0256A-AL2 – Part 6

Finally I'm doing something arguably slightly musical with my SP0256A-AL2! Playing it over MIDI. Part 1 - Basic introduction and getting started Part 2 - Arduino programmable clock Part 3 - Using a Raspberry Pi Pico as a programmable clock Part 4 - Using a HC4046 PLL as the clock Part 5 - Using an I2C SI5351 programmable clock … Continue reading Arduino and SP0256A-AL2 – Part 6 →

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! Arduino SP0256A-AL2 Shield … Continue reading Arduino SP0256A-AL2 Shield Design →

Arduino and SP0256A-AL2 – Part 5

This looks at another of the options from Part 4 - the I2C programmable Si5351 clock source. Part 1 - Basic introduction and getting started Part 2 - Arduino programmable clock Part 3 - Using a Raspberry Pi Pico as a programmable clock Part 4 - Using a HC4046 PLL as the clock Part 5 - Using an I2C SI5351 … Continue reading Arduino and SP0256A-AL2 – Part 5 →

Arduino and SP0256A-AL2 – Part 4

Having now tried both an Arduino and Raspberry Pi Pico as programmable clocks for the SP0256A-AL2, this post starts to look at some alternative solutions, starting with a HC4046 phase-locked loop, voltage-controlled oscillator clock. Part 1 - Basic introduction and getting started Part 2 - Arduino programmable clock Part 3 - Using a Raspberry Pi Pico as … Continue reading Arduino and SP0256A-AL2 – Part 4 →
