Build a dedicated Audio PC

haha!!!

well, the LiFePO4 wouldn't work for me. Its reading 3.3v but maybe it needs a little boost to get the voltage up another 0.1 or so.

Will try again later.

weird seen mine workin at 3.0v,
think jk has successfully done this too

Well got all the wiring sorted on the Zuma with all 5v lines taken away from the Pico so all Mobo 5v and drives, cards, etc. on 5v Teddy Pardo supply through a 12v relay which is switched in by the Pico.
Same with all the 12v stuff on the 12v Teddy Pardo supply through another 12v relay switched in by the Pico.
So the Pico is now only supplying the 3.3v and the start and shut down signals, still have this on the Anker Battery but must try the 12 smps some day to see if I am loosing anything.
Got the Paul Pang USB Card running and it is now feeding the Meitner, I still have the SOTM card installed and powered for some testing between both at some later point.

Best sound I have heard so far and the sub is now definitely in storage for another build at a later date.
Now for some serious listening this week.

I think it is all portable enough now for clocking up some mileage over the coming months, it will be interesting to see how it compares to some of the all battery Audio PCs cropping up around the country.

Best to put them on photobucket or similar, and use img tags with the link.

I did have it working on a voltage of 3.3V but it was with a number of parallel batteries - when I later tried with one battery powering the USB stick, it wouldn't boot, Nige, are you using only one LifePo4 battery?
