I have built a raspberry Pi Jukebox, specially modified for a handicapped user (voice feedback on all songs, large buttons) but I have one.... last.... problem.
The speakers I used ran off the analog port, which is fun. Alas, they had to be plugged into the wall - and I decided to make this portable for the guy. I wish to power the device as a whole using one of these babies. However, the speakers a 12 volts.
I actually own some of these guys:
Any help there? Thanks!
