that's pretty messed up

anyhow, i want a nostr signer usb, with a number pad, capacitative touch screen but epaper, and every time it gets a signal to input it scrambles the 9 numbers so you don't leave a consistent pattern on the surface, and all it does is accept a message hash and return a signature, and it has a timeout, like 5 minutes, so you don't have to input the pin every time if you keep using it, only when you stop for 5 minutes

can i get a grant to build this
