Hi All
I've built and used a version of DIYGUY999s Arduino Nano based sound systems in my 1/10th Aquarama build, and have tested same for my 1/5th build. It sounds OK, but the Nano is a bit limited in it's capabilities, the sampling with the ESP32 is 22Hz rather then the 8Hz limit on the Nano (ATmega 328) version which should improve the sound... I've recently ordered a set of 5 of his PCBs to test and build his updated ESP32 based sound system.

And I wondered whether anyone else has already done this..?
This is the Nano version: https://www.youtube.com/watch?v=sct1FfVY3TU (https://www.youtube.com/watch?v=sct1FfVY3TU)

By way of an update. A beautifully packed set of PCBs have arrived from PCBway. 5 custom boards with SMDs fitted, shipped via DHL to the UK, 60 dollars. I thought that was quite good, now I need to add other components including an ESP32 to one of the boards to start testing.

I'm about to try an experiment with a Teensy 3.2 with audioshield. I'd be interested to see (& hear) your results with this. The board looks very nice.

Hi Dave - just seen your post - nice looking board.
I used/abused the DIY99 guys eps32 code and stripped out all the stuff to do with switching, ESC control etc etc and eventually got my head around the important code elements.
I am currently messing around with higher quality dacs and also experimenting DSP editing waveform(s) in a synth app
Another interesting source on YouTube is XTRONICAL
Hopefully leads somewhere rather than the bin!
