Geode - Adding an Accessory Power Connector
getting Debian running on my National Semi Geode box, I quickly found the two USB ports on it a little limiting. Like any normal human being, I could just plug in a powered or unpowered USB hub, have my extra ports, and be done with it. I instead opted to go through the effort of getting a spare USB hub I picked up for $2 at Weird Stuff running on it, which is fitting, since they're both USB 1.1. It's an interesting USB hub - it was originally designed to be installed in a tower's floppy drive, exposing 5 USB ports on the front panel, and was powered by the standard floppy drive power connector. It also originally used a custom cable for the USB uplink (which was of course long gone), but the PCB has the pads for a USB B connector, so I soldered that on.
- Ground - black
- 5V - red
- 12V - yellow
This is all you need for the floppy power connector, so we're in luck.
Solder some wires to the underside of the power supply PCB.
And feed it out through some vents in the box. I salvaged the floppy power connector from a spare ATX power supply I had laying around my (currently very chaotic, post-move) apartment.
