Actually started playing with mine today again for checking out PSBT with QR. Gotta get a SeedQR setup so this is perfect timing. Love novelty mining though :P

Very very cool little device! Is it likely we'll see something like the NSD (Nostr Signing Device by LNBits) implemented in a future firmware? That would make me buy another one! A Nostrich proudly printed on it for a Nostr-edition might be well received (?).
