• Maybe actually a wireless mouse now!

    After finishing the first version of the PCBs for this mouse, I noticed a bit of an issue: I forgot to add battery power. It's difficult to have a wireless mouse if there's no battery.

    So, I've updated the PCBs with a battery connector and a charging circuit. On the suggestion of some helpful people in the KiCad Discord server, I also swapped out my half-assed PCB antenna for an IPEX connector, so I can use a premade external antenna. That should help it deal with the difficult transmit/receive conditions around a moving human hand.

    I've also updated the hardware design more, adding a mount for the scroll ball from an Apple Mighty Mouse.

    I'll try printing the parts in the next couple of days - maybe I can try it out, and see how it fits my hand!
