iLounger “Morcheeba” recently posted news of his disassembly of the Apple iPod remote. His webpage includes photos, pinouts and a schematic. In his latest forum post, he explains why he took the remote apart. We’d also like to note that iLounger “norque83” has posted disassembly photos of the Apple iPod remote.
