Hardware, and some firmware, for acoustic piano to MIDI controller conversion.
This is the re-do of #53 from a separate branch I followed https://stackoverflow.com/questions/74413366/ and https://stackoverflow.com/questions/1628563/ hopefully I did not mess up anything with the rebasing
Cables
Would using these parts make the ADCboard to sensorboard cables easier to build? Cable: https://www.digikey.com/en/products/detail/3m/HF100-40TP/3911407 Connector on the ADCboard side: https://www.amazon.com/dp/B00K2NTSJE/ Connector on the sensorboard side: regular jumper to be...
Another sensorboard with QRE1113GR. This time with two sensors and four holes for added stability. Same comments of #53 apply
I produced a bunch of variations on the sensor board very quickly, to account for the changes in my mechanical plan. Improvements: - [ ] Fix silk screen and labelling...
A sort of pie-in-the-sky idea, that isn't part of any milestone, or blocking anything: A board, conforming to the overall I2C/Qwiic scheme, which presents itself like the I2C UART on...
- [x] ~MicroSD card~ - [x] ~RTC~ - [ ] ~IRQ pins - [x] Check USB correct this time
JLCPCB being one of the easier (and still reasonably priced) ways for the average person to get a board assembled, I'm trying to keep the parts used to things that...
According to this paper http://mtg.upf.edu/mosart/papers/p35.pdf and this other one https://www.researchgate.net/publication/7603558_Touch_and_temporal_behavior_of_grand_piano_actions and how it discussed in some details at https://pianoclack.com/forum/d/289-scanning-speed-and-velocity-mapping-of-cybrid (and to less extent https://pianoclack.com/forum/d/243-diy-piano-sensors/33 ) it might be necessary to...
- [ ] Put all of the little 2 pin headers on a uniform 0.100" grid so that they can be held in place by a breadboard while soldering. -...
- [ ] Check ~IRQ headers - [ ] Confirm TLP185(SE footprint good / better
