Here’s a real simple desktop computer wireless headphone you can make using a JVC wireless headphones instead of buying those $200-300 bluetooth headphones.
Did you know that there’s plenty of 12V and 5V DC lines you can use off your desktop computer to power a whole bunch of devices? Well, this is a great example of that.
After [Parker] found an old set of JVC 900 Mhz wireless headphones (and a generic 900MHz transmitter), he cracked open the case to see what he could do with them. Realizing that the transmitter used a 12V DC source, he powered it with an unused floppy connector (which provides +12V, +5V, and two ground lines).
