Show HN: I wrote a small lib to turn a USB gamepad into a Bluetooth one

I had two old USB gamepads lying around that I wanted to use, but my computer is too far from the couch, so I wrote a little ESP32-S3 firmware that turns USB gamepads into Bluetooth ones.

You connect your gamepad to the ESP32-S3 with an OTG cable, power the ESP32 with either 5V somehow or a powered USB hub, and now you can pair the controller via Bluetooth to your PC!
