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 →

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 →

Arduino with Multiple Displays – Part 2

As I mentioned in my last post on Arduino with Multiple Displays I'm going to look at other microcontrollers too. This post takes a wander through my Waveshare Zero and similar format boards that each support one of the RP2040, ESP32-C3 or ESP32-S3. Warning! I strongly recommend using old or second hand equipment for your experiments. … Continue reading Arduino with Multiple Displays – Part 2 →

Having played a bit with ESP32-S3 now, in the of the Waveshare Zero format boards, I'd quite like to have a version of the ESP32 WROOM Mozzi Experimenter PCB for the latest ESP32-S3 DevKitC board I've found. This is the introductory post that is my "notes to self" as I get to know the boards. … Continue reading ESP32 S3 DevKit →

Duppa I2C MIDI Controller – Part 4

This is revisiting my Duppa I2C MIDI Controller this time using a Waveshare Zero format device. Part 1 - getting to know the devices and testing them out. Part 2 - adding MIDI to the LED ring and I2C encoder. Part 3 - adding normal encoder, plain potentiometer, and endless potentiometer control. Part 4 - revisits the idea with … Continue reading Duppa I2C MIDI Controller – Part 4 →

Waveshare Zero, Pimoroni Tiny, and Neopixels

I want to revisit my Forbidden Planet “Krell” Display looking at an alternative way to do the electronics. In particular, I'm looking at how I might embed a microcontroller in each display. This post is a short diversion into the world of some Waveshare "Zero" format devices and a bit of background on driving programmable … Continue reading Waveshare Zero, Pimoroni Tiny, and Neopixels →
