I was excited for a minute thinking maybe someone finally made a wired Logitech trackball without having to pay $200 on eBay for a used one encrusted with someone's excreta.

But no, here we have... replaced a micro USB port with USB-C. Something fixed with a $2 cable at Ikea. The epitome of first world problems and he even had a custom PCB made. That's not even worth the academic part of this.

He didn’t even make it, someone else did… I’m always amazed to see such things at the top of HN.
