Hey @noisio, I bought a kit from you at #37c3. These synths you made are genuinely so fucking cool and I had a blast building them (and now playing around with them)
Thank you so much for going through the stress and programming one more microcontroller for my LFO/EG even though you were super busy helping others get their stuff to work. I really appreciate it <3
I didnt quite finish my ATBase at congress but now (at 6am) I can exstatically say I got it to work!
@noisio Its still a bit janky because I didnt have a DC power jack anywhere at home so I just cut apart an old usb C cable I made and soldered the two power wires to the battery pads you put on there.
The usb cable itself I wired through the DC jack hole (after removing the jack) which unfortunately didnt work at first.
I had to bridge two of the dc jack pads which I did with that lovely green wire and voilà! A PERFECTLY WORKING ATBASE THAT SOUNDS SO FUCKING COOL.
@noisio The usb cable I used was a Type A to Type C cable. I primarily build mechanical keyboards and decided a while ago to get into making the cables myself and that was one of my first attempts that didnt turn out too great. Perfect for reusing :)
I cut off the type C part and exposed the wires there, The other type A side I plugged into my lab bench power supply that provided the ATBase with 5v at 2 amps (I checked with my multimeter, 4.99v)
@noisio
>USB-C Power Delivery can give you up to 20V, but for this you'll need a small extra circuitry.
Uff, tell me about it. You dont want to know how much time I spent in order to actually somewhat understand how usb c pd works.
usb c for all future kits sounds bloody awesome!
@noisio Oh shit, your right. I just read the datasheet too! Thats really odd... Unfortunately I wont be able to test it for you before sunday. But Now I'm interested in this too. I'll keep you updated.
Judging from my video in the OP I wouldn't say it sounds much different than the ones you had on display at #37c3, right?
@noisio oh dont speak to me about regulators today 😂
I fried my only esp32s2 devboard I got gifted at congress this morning and spent the majority of today researching this thing's schematics to understand how those little fuckers work until I eventually found another board I could steal a similar regulator from.
The difference was, it had a completely different footprint so I had to handwire the whole thing with directly to the pads... It was a pain in the arse to say the least. BUT IT WORKS!!
