I’ve uploaded a new program to the repository, a MIDI Sequencer that allows you to use miniMO as a pattern sequencer with any MIDI device.

- This article will be most useful to you if
- you can write and understand basic programs
- you would like to modify the setup of the timers or other peripherals within the microcontroller
- you cannot make clear sense of lines like
ADMUX |= (1 << ADLAR);
miniMO is a reprogrammable synthesizer module, designed to encourage everyone to try modular synthesis. Currently there are two models available: one is PCB-based with soldered components, whilst the other (code name Noisette) is built on 3D-printed parts and requires no soldering. I will show you how to assemble and program the latter model.More…
A few pointers on the subject of DACs, PWM, and timers, for future reference.
Last weekend I started doubting my setup miniMO. It’s been a while since I worked out the details, and wondered if I had chosen the timers correctly, so I went over everything again.
This is all the reviewed information, written down while it’s still fresh in my mind:More…
With five new modules up and running, I’ve revised and uploaded the DCO code to Github. It has been a while since I last used Github, since I normally work with svn; I was pleasantly surprised that I can use tortoiseSVN with it.
Following steps: decide on the open-hardware license, figure out ways to distribute it, publish a video demoing the unit, start modeling the case, and start spreading the word a bit more.
I received the PCBs last Friday and built a few MOs over the weekend. I’m very satisfied with how things turned out; the PCBs look sharp, I had no difficulties in soldering the components, and everything works correctly. I found I made a couple of errors with the design, but both have easy fixes and functionality isn’t compromised.More…
