It looks interesting. I'll have to hook up a board this weekend and try it. I was just playing with Nerves [0], and trying to see if I could just use Erlang instead of Elixir, since I started learning Erlang using Gene Sher's "The Handbook of Neuroevolution Through Erlang" [1] a year and half ago or so.
