[Cthulhu_]

I love tiny things like that, there's already so much you can do with it.

I wrote a thing way back when, probably a TI chip or something, which had like 300ish? bytes of memory. It got commands from a serial in (which was a bluetooth device, commands were sent from a java application on a laptop), the commands were a simple self-made thing which was a command (two numbers) and an argument (like, "set speed to 10"). That then controlled a PWM for the engine and things like that. RC boat with a few hundred bytes of memory.

I'm reinventing all that now with using raspberry pi's and arduinos and such. I just got an EPC32, which is a $5 device that should have wifi and bluetooth and such built in already.
