On my bench I have a test mains power input for testing Xboxes along with a test AV cable connected to a TV.
Today I wired an Xbox power safety device into the mix. There’s a tear down of this highly over-engineered device on the EEVBlog video: EEVblog #1164 – Xbox Engineering Baptism Of Fire.
Microsoft made this to cover for defective mains power connector in their earliest hardware versions. The problem was that the socket was only soldered into the board and didn’t have sufficient mechanical support. The solder joints could wiggle around, become loose, get hot, and then let go the magic smoke.
Anyway this device is both a fuse and an earth leakage detector, so very happy to have it as part of my setup.
