I've ordered the PCB, it should arrive soon.
Some more sound examples:
(Cauldron / Amstrad)
(C64 SID synth)
- http://battleofthebits.org/arena/Entry/ ... ter/26509/
(personal creation, for zx spectrum)
there is still some noise and hiss when recording from the breadboard, but it might be some bad connections or ambiant interferences, I think it won't be present in the final version. (I don't remembered having this on my prototype board)
It can then play chiptunes without the need of a complete Amstrad, ZX spectrum or Atari ST! A pocket emulator.
but more than this, this board has:
- a low pass filter
- arduino nano
- SD card reader
- Midi DIN-5 connector
So we can use it for the creation of other projects:
- Mozzi synth (see here: https://sensorium.github.io/Mozzi
- SID player and synth emulator
- 1-bit music player
- no AY-synth at the moment, but we can use a photoresistance for turning it into a noise and random music generator!
I'll sell the PCB card alone (if it works as expected), for a cheap price, and also some complete kits and assembled product.
