You've hooked a NN up to a PID? How's that going? It's hard enough tuning those things by hand using squishy human brain networks.

I haven't done it myself yet, it's on the to-do list. There is a lot of academic material on PID autotuning, not always with neural networks but that seems the most straightforward way. A Raspberry Pi is probably overkill for the job, actually.
