Can we combine a #Minibits dev, a #ESP32 dev, and a #3Dprinter to combine these things to build something like this?

I'm thinking we could use and ESP32 with AA batteries, to link to a Minibits #wallet, just to show the account name and #Sats balance, with an on/off button, and a chunky keypad as shown for a passcode.

Nice and simple, so even quite young kids can have one.

Looking like a kids' calculator would be good opsec fwiw.

The wallet itself could be handled by a parent for actual functions, like transfers.

I guess the next step up, potentially for older kids would be to have something like this linked to an app like #Jan3's #Aqua wallet, for #Lightning and on-chain #Bitcoin balances.

Maybe stick a receive QR code on the back so anyone can #zap it.

Or does this type of thing already exist?

Or is this idea flawed?
