Starting this so those of us with some DIY type ideas for their RPi builds can give some ideas to others for some DIY fun.
I picked up a couple of nice Sake bottles the other day and they came in a nice light box. I will ultimately build a Linear supply in side to power the the RPi that has an IQAudIO DigiAMP+ HAT on it and currently powered by a 19V SMPS also from IQAudIO. Just attached some Banana type binding posts and put an old dead toroidal in the bottom to keep it from moving around.
This powers a pair of Emotiva ERM-1 speakers in my dining room - with a direct LAN cable.
