It came to my attention recently that you can order a little RISC-V computer for about $10, depending on where you get it. The Milk-v Duo runs linux and has networking capabilities, It has a 1GHz processor, and a 700Mhz processor, although I can only use the 1Ghz processor for the Linux system. My version has 64MB of RAM which is more than enough to do some computing.
As you can see the computer is very tiny, it has no Wi-Fi chip included but you can start an ssh connection over USB to begin computing with the device. The offical system image comes with a few important programs, including busybox, and python, so there's a lot that I'm sure you can think of doing with this little computer.
I wanted to run some tests so I wrote this little script to calculate prime numbers. There are probably more efficient ways to do this that were thought of ~2000 years ago by a Greek guy, but this will do for my purposes.
Here the code is working just fine, I have it looking for prime numbers over 1,000,000. I'll keep this running until it finds the 52nd Mersenne prime and I can let the fellows over at the Great Internet Mersenne Prime Search (GIMPS) know. Then, once I've collected my $3000 reward from them for finding that prime, I'll be able to retire comfortably. Huge thanks to RISC-V computing on the Milk-v Duo for helping me with this.
