Atari Synth Cart Controller

This project uses my Atari 2600 Controller Shield PCB in reverse, to allow the Arduino to act as an Atari keypad controller and thus allow it to control the Atari Synth Cart. https://makertube.net/w/ryCciwFyQQpcs1Q4Wwy52x Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive … Continue reading Atari Synth Cart Controller →

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 →

Arduino and SP0256A-AL2 – Part 3

Following on from using an Arduino as a variable clock in Arduino and SP0256A-AL2 – Part 2, I have some ideas for a few options, but this post looks in detail at using a Raspberry Pi Pico as the clock source. Spoilers: it kind of works, but isn't quite the answer I need yet... Part 1 … Continue reading Arduino and SP0256A-AL2 – Part 3 →

Arduino with Multiple Displays – Part 3

Whilst messing around a little more with my Arduino with Multiple Displays – Part 2, I've optimised the code a little and found out a bit more about these displays! In this part, I'm actually using a PCB that can hold four displays, powered by a Waveshare Zero device. More on that here: Waveshare Zero Multi … Continue reading Arduino with Multiple Displays – Part 3 →
