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 →

MiniDexed 3D Printed Cases

I've used my modular Raspberry Pi 2,3,4 A+/B+ Synth Case to create a variant for the two versions of my RPi Zero MiniDexed IO Board PCB Design. There is also now a version for my MiniDexed Raspberry Pi IO Board V2 Design too. The OpenSCAD file should allow for a range of variants to be produced, but I've … Continue reading MiniDexed 3D Printed Cases →

picoDexed + MiniDexed EuroRack

Since attempting my picoDexed + StackyPi + MiniDexed EuroRack build and failing, I've found another Pico-to-Zero board that is provided as open source, so I've had some made. This post details how to get that running with my MiniDexed Zero Eurorack module. Warning! I strongly recommend using old or second hand equipment for your experiments. I … Continue reading picoDexed + MiniDexed EuroRack →

picoDexed + StackyPi + MiniDexed EuroRack

Now that I have a picoDexed with a display an encoder it is very tempting to create a version of my MiniDexed EuroRack PCB for it. But as a short diversion, there is another possibility - can I use a RP2040 that is already in a Pi Zero form factor with my existing MiniDexed EuroRack … Continue reading picoDexed + StackyPi + MiniDexed EuroRack →

MT32-Pi on my EuroRack MiniDexed PCB

This is great. I was asked by Michel (mragutlich) if I knew how to build MT32-Pi to configure it for my MiniDexed EuroRack PCB but I don't and there isn't a lot of information apparently on how to build it from source. So I offered my Rebuilding my Ability to Build MiniDexed post which talks about … Continue reading MT32-Pi on my EuroRack MiniDexed PCB →

MiniDexed EuroRack PCB Build Guide

Here are the build notes for my MiniDexed EuroRack PCB Design. This is a DIY module only for use in my own DIY system. Do NOT use this alongside expensive modules in an expensive rack. It is highly likely to cause problems with your power supply and could even damage your other modules. Warning! I strongly … Continue reading MiniDexed EuroRack PCB Build Guide →

Almost “All in one” MiniDexed IO Options

As I was browsing around I happened to notice a couple of interesting add-on boards that comprise a OLED display, rotary encoder and some buttons. With the addition of a I2S DAC (or just using the existing PWM output) these make a really interesting option for MiniDexed IO. Warning! I strongly recommend using old or … Continue reading Almost “All in one” MiniDexed IO Options →

MiniDexed EuroRack PCB Design

I've seen a number of EuroRack format MiniDexed versions now, from 3D printed panels and designs, right through to commercial modules. It's something I've been meaning to do for a while, so this is my first attempt at a take on a 8HP EuroRack format MiniDexed using a Raspberry Pi Zero 2 W. This is … Continue reading MiniDexed EuroRack PCB Design →

AIY Voice HAT and MiniDexed

Someone asked on the MiniDexed forums if the Google/Raspberry Pi AIY Voice HAT could be used with MiniDexed. This reminded me that I had V1 of the kit tucked away in a corner somewhere, so decided to finally take a look at it! Warning! I strongly recommend using old or second hand equipment for your … Continue reading AIY Voice HAT and MiniDexed →
