Well life has intervened again and had to fix one of my sons headphones. Complete hack job but he loves them. It appears beats headphones have a flaw resulting in mechanical failure. SAME SPOT months apart from taking headphones on/off. If you would like to see the fix check out the beats fix project. Moving on....

It appears my OLED has stopped working resulting in me re-soldering all joints and having the same result, no screen. I have a bigger screen which I may attempt to move to OR just finish the code with FTDI programmer so I can see results.
