I think I will actually build one

Please note that Kruh wallet can't function as normal hardware wallet, but more like a cosigner in a multisignature setup,
so every time you turn it off from power you will wipe his memory, and you will have to import your key every time you turn it on.
Other thing that I don't like is the fact that code is new, not time tested and there could be some hidden bugs even in this simple code.
This wallet has good and bad sides, it's very cheap and I think it serves great purpose for multisig device.

Here are some images and videos how Krux works in real life:

Thanks for these clarifications! So it's really a simpler version of SeedSigner basically. Pity it has no persistent (secure) storage, I assumed it had.
Didn't an M5Stack with secure element exist? I think it does, but without camera.

I'll have a look if maybe a secure memory chip can just be added (soldered) into such an M5StickV device and firmware modified to make use of it.
