Is it useful? Maybe. I have a couple of existing projects that would benefit from a rotary knob, but not enough code-space is left to add encoder handling. Serial comms is already working, so this is the simpler way to make it work. A little quiz: {1,-1,0,-1,0,0,1,1,0,0,-1,0,-1,1,0}

I will have to think about debouncing a bit, but in general it works quite nicely. In this picture it controls the lights used to illuminate it. The lights understand serial, so the knob only has to send '+' or '-' to adjust brightness. It also works very nicely as a volume knob for amarok, kmix ... only requires linux, KDE4 ;-) The ATtiny85 is hidden on the other side ;-) As usual you can have all design files and code. Search for "Serial-Knob" and take a look inside the "ATtiny_projects" repo for code: [ 1 ],[ 2 ].

These 0603 footprints I made... they shouldn't have been any smaller!
