AY-3-8912/8910 Hardware Emulation – Part 3

This continues my series looking at hardware emulation of the AY-3-8912/8910: Part 1: Introduces the AVR-AY projects and available boards and how they go about using an AVR microcontroller, usually an ATMega48, to emulate an AY-3-8910 device. It walks through the functionality of the provided firmware. Part 2: My own experimenter PCB based on an overclocked … Continue reading AY-3-8912/8910 Hardware Emulation – Part 3 →

Atari 2600 Controller Shield PCB Design

This is an Arduino Uno shield format PCB for hooking up two Atari 2600 style controllers to an Arduino. Note: this iteration of the design doesn't really do the paddles very well, but it works fine for joysticks and keypad controllers. Atari 2600 Controller Shield PCB Build Guide There are some updates here: Atari 2600 Controller … Continue reading Atari 2600 Controller Shield PCB Design →

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 →

Forbidden Planet “Krell” Display – MIDI CC Controller

This takes my Forbidden Planet “Krell” Display and adds some potentiometers to turn it into a MIDI CC message controller. Forbidden Planet “Krell” Display – MIDI CC Controller – Part 2 https://makertube.net/w/vz9RucdW1oi2XzAqPBa96g Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any damage to expensive instruments! If … Continue reading Forbidden Planet “Krell” Display – MIDI CC Controller →

ESP32C3 OLED Mini MIDI Montor

I've picked up a couple of really neat, small, ESP32C3 based boards with a built-in 0.42" OLED display and so whilst wondering what to do with them, I thought a small MIDI note monitor might be a bit of fun. https://makertube.net/w/3KWE9QUD2Qs9chcWwpX99R Warning! I strongly recommend using old or second hand equipment for your experiments.  I … Continue reading ESP32C3 OLED Mini MIDI Montor →

Forbidden Planet “Krell” Display – MIDI Notes – Part 2

As I mentioned in Forbidden Planet “Krell” Display – MIDI Notes I'm building a simple (in function, not in execution it would seem) MIDI note display out of my Forbidden Planet “Krell” Display. The first attempt showed there is potential, but I was rapidly reaching the limits of what an Arduino could do for me using … Continue reading Forbidden Planet “Krell” Display – MIDI Notes – Part 2 →

Forbidden Planet “Krell” Display – MIDI Notes

This is my first attempt at some kind of MIDI related visualisation for my Forbidden Planet “Krell” Display. I thought I'd start easy and simply map MIDI notes onto the segments and create a simple display. That turned out to be an awful lot more involved than I imagined... In fact, this is quite sub-optimal … Continue reading Forbidden Planet “Krell” Display – MIDI Notes →

Forbidden Planet “Krell” Display

If you're not familiar with The Forbidden Planet, then it is an iconic 1956 Sci-Fi movie with an absolutely ground-breaking soundtrack of "Electronic Tonalities" by Bebe and Louis Barron. In one scene, when the humans visit an alien (the "Krell") science lab there is a large set of display dials around the room that logarithmically … Continue reading Forbidden Planet “Krell” Display →
