I am not really a fan of breadboards, but for a design so trviail I really didn't feel like spending time and money to produce PCB. I hooked up everything on my desk and got it running in no time. The whole thing should be enclosed anyways, so it doesn't matter if it's ugly or not.

I also did some power optimization. Instead of linear regulator I got $0.80 MP1484 step down module from e-bay. I felt kinda terrible to allow 12-5=7V drop across the poor component. With current bursts of up to 500mA, I can only imagine how short the linreg would survive.
