Turning a $20 smart ring into a DIY MIDI controller (Colmi R02 + WebMIDI API, hardware and DAW)

video upload by Floyd Steinberg

"Here's a super inexpensive #bluetooth #smartring which will dump raw data if politely asked to. So let's try to use that as a #midi / #synthesizer controller! Based on the work of ‪@atc1441‬ , more after the table of contents

00:00 demo: filter control, Y axis
00:19 hi / what is this?
00:41 shoutout to Aaron Christophel ‪@atc1441‬
01:01 Roland Neova / how to determine your ring size
01:22 what's in the box / hardware overview
02:01 it's not a bad smart ring!
02:22 mission statement
02:35 code overview & APIs
03:20 event handlers and MIDI CC
04:03 services and charateristics
04:78 explaining the hardware setup
05:48 patch /mod matrix setup
06:13 it's working! :-)
06:32 ... but it's very slow!
07:08 there's a custom firmware that speeds up data transfer
07:31 interpolation
08:05 example: using this in a DAW with LoopMidi
09:19 conclusion: not perfect, but the hardware certainly can do more
10:40 a very subtle joke / subscribe plxplx?

via this listing, also on Reverb

"Midibox MB6582 Maxed Out with eight SID 8580's C64 chips, MIDI capable. Includes original C64 power adaptor.

Condition is Used and it is DIY. It's maxed out with eight 8580R5 SIDs. They are noisy. Beautiful blue panel from Julian. LED's though not too bright. A nice illuminated fan on the back with the "overdrive" pots. Loaded with latest firmware. Has the clear custom plexi window to protect the LCD. The encoders do tend to "bounce" but from my understanding it's normal, and totally manageable if you don't twist too quickly. Sold as is. Sid heaven! Why build your own when you can buy this one?"

Korg Mono/Poly garage-find | Did it still work after all those years?

video upload by Espen Kraft

"The Korg Mono/Poly belongs to a friend of mine who (if my memory serves me right) did find it in a garage somewhere, alongside a Roland Jupiter-4 which was beyond repair from what I can remember he said. This is a short edit from a longer video I once had on my channel.
Oscillator 1 on the Mono/Poly did not work and that prevented me from doing a couple of things with it, but it still worked and what you hear in this video is what I got out of it. Only the kick drum is a sample. The rest is the MP you see here.
Since this video was made the synth's been repaired/restored and is now working 100%. The dust did come off.
