 The NeoKey Trinky. This is like a USB key or a thumb drive, but it accepts a keyboard keyswitch, mechanical keyswitch. You solder it onto there, and it's got the capacitive touch on the end. You can do any sort of HID thing, so this can be MIDI. You can do control-alt-delete button. I've got a Raspberry Pi 400 computer sitting right here. This is going to, when I press it, enter in my ToeBeans emoji. It is the NeoKey Trinky, and it is a mechanical keyswitch USB key style trinket with an underlit NeoPixel and capacitive touch.
