Duppa I2C MIDI Controller – Part 3

This is a follow up post to Part 2 expanding on the code and adding in some of the alternative control options I mentioned. 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 … Continue reading Duppa I2C MIDI Controller – Part 3 →

Duppa I2C MIDI Controller – Part 2

This is a follow up post to Part 1 where I'm starting to look at MIDI applications and a range of control options. 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. … Continue reading Duppa I2C MIDI Controller – Part 2 →

Remotely Analysing a Keyboard Matrix

I've been having a conversation on discord helping someone to try to work out the keyboard matrix of a keyboard in order to eventually use it with a microcontroller. But discord being discord, its fine for chat, but we're both starting to lose track of where we're at in the analysis, so I thought I'd … Continue reading Remotely Analysing a Keyboard Matrix →

Duppa I2C MIDI Controller – Part 1

I've had my eye on Duppa's rather neat looking I2C LED rings and rotary encoders for some time and finally pushed "go" on getting a couple. I want to use them as the basis for a MIDI controller but this post is just my "getting to know them" post. Part 1 - getting to know the … Continue reading Duppa I2C MIDI Controller – Part 1 →

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 →

CakeBox 30HP EuroRack Lid

Now that I'm doing more messing around with EuroRack style modules, I was on the lookout for a simple means of testing them "on the bench". As I was scanning around, for different ready-made containers I might be able to use, I settled on the spare plastic cake boxes we have lying around. These often … Continue reading CakeBox 30HP EuroRack Lid →

Getting Started with Daisy Seed

I've finally managed to get myself a Daisy Seed from Electro-Smith, so as is becoming usual, this is my "getting started" notes-to-self post. Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible for any damage to expensive instruments! If you are new to microcontrollers, see the Getting Started … Continue reading Getting Started with Daisy Seed →

ION iDM02 and Arduino

I picked up an ION iDM02 drum module, with five pads and a single pedal, and most of the frame missing a while back and always wondered if I could get it doing something interesting. As is becoming usual with these types of posts, this is a collection of things I've found out about the … Continue reading ION iDM02 and Arduino →

Arduino Clock Generator Shield PCB

This is an Arduino Uno shield design that can be used to provide up to six clock generator outputs for a sequencer. I've built it to use with my Arduino Euclidean Gate Sequencer. Arduino Clock Generator Shield PCB Build Guide Warning! I strongly recommend using old or second hand equipment for your experiments. I am not responsible … Continue reading Arduino Clock Generator Shield PCB →

Cheap Mini Amplifiers

When I'm looking around for an off-the-shelf module to do something I can sometimes be a little guilty of seeing a range of cheap implementations and just getting one of each to have a go with them, rather than research them first. Small, cheap amplifiers was one such set or purchases a while back, so … Continue reading Cheap Mini Amplifiers →
