Firefly: Air gap Ethereum hardware wallet

We’ve finally put together a quick demo of the Firefly, a DIY Air-Gap Hardware Wallet for Ethereum you can build at home for $5 in parts. We will be releasing the source code, hardware design and 3D models over the next few weeks under the MIT license.

Here's a very cute, secure hardware wallet to store your ether called Firefly. It's based on cheap Arduino parts and should be relatively easy to build yourself. Also nice to see the team crowdfunding their effors instead of starting an ICO.
