Open Source Hardware Wallet Project

[cakir]

Hello guys, I propose to create "Open Source Hardware Wallets" project.

There're lots of "open source embedded mini computers" like arduino, raspberypi etc.
Also those mini computers run linux distros.
Why don't we develop an "open source hardware wallet"?

I think we can develop 3 types of those wallets:

Open Source Hardware Wallet Mini;
A raspberrypi ~40$ (to run multibit etc lightweight wallet, because of lack of memory to save blockchain data)
Camera module: ~30$ (to read qr codes)
Mini LCD: ~15$ (to show balance etc)
Numeric Keypad: ~5$ (to unlock wallet, pin entering would be vulnerable)
Wifi adapter: ~10$  (to download blockchain only)
simcard reader: ~10$ (to broadcast tx'es only)

~110$


Open Source Hardware Wallet Standard;
A raspberrypi ~40$ (to run bitcoin-core wallet)
Camera module: ~30$ (to read qr codes)
Mini LCD: ~15$ (to show balance etc)
Fingerprint scanner: ~50$ (to unlock wallet, pin entering would be vulnerable)
Wifi adapter: ~10$  (to download blockchain only)
simcard reader: ~10$ (to broadcast tx'es only)
64 GB microSD card: ~15$ (to save blockchain data)

~170$

Open Source Hardware Wallet Plus;
Gps (if you loose/are stollen wallet, it sends location data via simcard, and you can send a command via sms to wallet and it starts to send GPS data to you via simcard).
RFID/NFC etc - (if bitcoin companies develop a pay&pass system with one click, these units can be added on it).

Probably ~250$

What do you think about a hardware wallet that you can completely rely on? How can it be developed further?

Ps: I'm not selling any hardware wallet or releated parts. I'm not planning to sell this kinda product.  Anyone can create/develop similar projects, I don't develop such thing right now, This is just a thought.
