I've been wanting a hardware wallet for Bitcoins and Alts for ages, but I just can't justify the cost, especially living in Australia, as postage to the middle of nowhere certainly adds up big time. I stumbled upon a fantastic little project based on the Trezor offline wallet over at https://www.pitrezor.com/2018/02/pitrezor-homemade-trezor-bitcoin-wallet.html and I'm thrilled with it. The instructions are super easy to follow, no questions asked. I remixed mobi_electronik's design of the keychain because I really love that one and have been using it for a while now. This remix uses the affordable Ebay 0.96" OLED 128x64 blue screen (AU$3.70), two massive buttons, small MicroSD (2G) and a Pi Zero. My buttons are huge, but all I had lying around! They're 12mm square, 5mm hole, 6mm depth. This case should fit most small "tac" style buttons with ease. I've extended the covers over the HDMI, camera and power as they're not needed for this project. Follow the hardware setup from Yannick's blog - it's a breeze to follow. Edit: I made a slight change to cover the MicroSD slot to make it more secure. I also cut the text right through the case; it would probably look great with some back illumination or just colored card stuck inside. Feel free to modify for your own needs. https://www.tinkercad.com/things/fyXPoQDAAQ7-pi-trezor096-oled/editv2 Oct 2018 Edit: I created a different lid to match the original style of Trezor. The buttons are side by side. Both versions are in the download, so you can choose whichever one you like.
