Hi,
I am also looking for a wired magic mouse.
In my quest I found photos of the internal :
[guide|1240]
You can see the bluetooth chip to replace :
Broadcom PCM2042
This chip is an all integrated HUD bluetooth device from broadcom.
So there could be three solutions :
- there is a test mode on the chip which allows to plug on it wires with a kind of standard format which can be then treated in an arduino configured as hud device for the computer
- remove the chip, and plug the inputs directly to the arduino configured as hud device
- remove the chip, move it to an external case with wires, put a bluetooth receptor to usb in this external case and shield completely the case from HF
I hope this bit of information could serve as motivation for someone.
