On most keyboards and mice the cables are not soldered on the inside but just a quick connector.
You can get a female/male versions of this connector placed on either side of an attiny85 for a quick solderless implant no one will ever see.
Then just undo 2 screws, plug your implant inside the mouse/keyboard, screw it back.
To make this harder intentionally strip the screws with a drill, understanding you will never be able to repair that unit again.
- IIsi50MHz 5y agoSeems there are special drill bits for removing stripped screws…

- hinkley 5y agoMy anecdote was a bit old and I’m certain some of those devices had soldered cables, meaning that a sheared wire couldn’t be handled by buying a new chord or combining parts of two mice. Because I specifically looked for that a few times with no luck. But they’re right, these days when you crack open things you often find a connector soldered to the motherboard and the cable is merely plugged in. I think it’s just easier to manufacture. Pick and place, bulk solder and then a machine to plug in the cable, fast as you like, maybe with a loop in it as a poor man’s strain protector.

Well, if you're stealing them, you only need parts from one mouse: cut the cable close to the mouse, untangle it from whatever crap it's locked to, take mouse and cable home with you, disassemble mouse, feed cable back though (I think it's called) grommet, strip cable, pick out wires, solder wires to approriate mouse internals, reassemble mouse, done. You have a working mouse with only slightly shorter cable than before. The point of using soldered cables for security is that setting up a soldering iron near a computer is conspicuous, so you get caught if try to install a attiny85 inside the mouse that way. You can still steal stuff just fine.
- victorhooi 5y agoWhen you say strip the screw - do you mean strip the screw head, by drilling out the head? That's evil... (Or do you know some way to strip the thread itself).
- lrvick 5y agoYeah just intentionally drill the head so those screws are not coming out again without power tools which should be obvious in the open where they are deployed. Or just epoxy the whole thing together.
- mhb 5y agoEpoxying the screws in might be easier?
