A howto video guide that walks through the instructions on how to make a DIY Bitcoin Hardware wallet running the same Open Source firmware that is on the Blockstream Jade. The DIY hardware works straight off the shelf an in this video I look at using an M5Stack ESP32 Basic ($40 USD), an M5StickC-Plus ($20 USD) and the TTGO (Lilygo) T-Display. ($10 USD) This is easily the best value Bitcoin hardware wallet available.
