A Bitcoin accepting Keurig built at HackBeanpot in the last two days. We tore apart a Keurig, put an Arduino Uno in it with a wifi shield, an IR sensor and some LEDs. We put it back together nicely and added a Bitpay integration. It now makes you a cup of coffee when you pay it in Bitcoin and place your mug in it. Users can also brew with a donated cup of coffee from below.
Here are some photos of our build. We will be writing a step by step guide in the next few days. Photos will continue to be posted until we pitch it at the hackathon later today. Enjoy!
