Randomly stumbled on this today - a proto board CMOS synth demo. Sounds pretty good for a bunch of CD4xxx ICs !

Just noticed this today - seems all the archiving activity has been noticed by NCBI / NLM staff. Thankfully most of SRA (the Sequence Read Archive) and other genomic data is also mirrored in Europe.

Timely, since I recently misplaced my big bag of 100nF through hole MLCCs, somehow.

3D printable. To my knowledge, there isn't another MIDI breakout for Disting that has both 5 pin MIDI DIN and TRS sockets.

The EuroPi is a neat multi-functional eurorack module by Allen Synthesis, based on the Raspberry Pi Pico (and soon to be even better with Pico 2 support which should make it feel snappier !).

When I started sourcing parts to build one, I found that the OLED modules and buttons in the original design were a little more expensive for me to acquire in Australia, compared with the more common Ali Express versions. I also really wanted the design in KiCad. I reworked the EuroPi hardware to use these alternative OLED variants and cheaper tactile buttons. I also moved around some buttons and jacks to my own preferences (making it more like the uO_C Ornament and Crime layout).

This is the result - the screen is slightly offset to the left (which I'm guessing is why Rory Allen's original design may have used less common OLED modules), so I've tried to maintain symmetry by 'filling in' the asymmetrical part with the silkscreen on the panel. I think it works okay (it's not triggering any OCD in me anyway !).

Electronic music design legend Roger Linn talks about the process from scrappy DIY prototypes to commercial production of his 3-axis touch sensitive MIDI controller.

jepyang just posted these schematics ( https://github.com/jepyang/Mac-Salad ) - it's a neat looking combo of utilities with some interesting normalization. A vactol crossfader/panner, envelope follower, wave folder thing, rectifier, AND+OR analog logic, a slew type thing, some VCAs.

.. and new prototype hardware with 8 inputs and 8 outputs !

A project looking to use MIDI (2.0 !) over CAN bus within a modular system. Appears to be a nice foundation with some hardware and software designs - will be interesting to see if this goes anywhere.

... another thing added to the to-build wish list :)
