Long ago I was really into bitcoin mining. It was a fun project that actually generated a little income at the time. This was way back when GPU mining was still a thing. I stopped playing around with Bitcoin a few years ago and sold all of my equipment(except for a few block eruptors). I also sold all of my bitcoins when it was around $700 and just called it quits, I had no time to be playing around. Now that it is up to $4000(!), I thought it would be fun to make a little bitcoin lottery device. The basic idea is that you solo mine with a raspberry pi and a block eruptor, and hope you mine your own block. It uses so little power, and my Pi is running anyway. If you happen to mine a block you will get 12.5 bitcoins, in USD that is around $50,000. Yeah, really. However, it is extremely unlikely that you will mine a block, but it is still possible, and probably close to the same odds as the real lottery, but much cheaper(cost of electricity for the Pi).
