Planning to show this setup tonight:
Truely FOSS Satochip javacards https://github.com/Toporin/SatochipApplet initialized with an airgapped, stateless nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl .
The cards act as a hardware wallet without a display, but with a PIN protected secure element. Mess up the PIN 10 times and the card is bricked. Blanks cost ~2 dollars with chip, ~5 dollars with NFC support. Can compare with #TapSigner, #BitKey and alike.
Find the modded images supporting the smartcard readers here: https://github.com/3rdIteration/seedsigner/releases
Parts:
- a generic smartcard reader (here ACR39U https://a.aliexpress.com/_EzkLWc9 + microUSB adapter)
- can use the same cards as the SpecterDIY

Sparrow Wallet works out of the box 
with these https://satochip.io/ cards (same when DIY).
Even tested on TailsOS.
Electrum Wallet also has a fork (close to be merged) which works, not in the Bitcoin Core HWI yet.
An iOS and Android app is in the works. Hoping for Nunchuk to follow.
I'm ordering all of those parts right now.
