Supaspin code,

'Supaspin' a turntable psu based on an Arduino, designed by a guy called Richard Balmford, I beleive DIYAudio featured near the end of 2021, I can see the build files and readme on github but no reference to the source code, any help would be appreciated, I am not sure about using github so maybe the code is there, much appreciate any help as I have already built five units which I cannot use.....
