The thing is real. I just removed the headers by overlaying rendered gerber files.

The encoder fits

almost nicely. BUT, the footprint is for a different type ;-) Good enough for a prototype.

What you can't see: there's an ATtiny85 on the bottom side that will do the decoding. The firmware will support "step / direction" output or send status changes via serial. The push-button can be used to switch between various modes.

If I can figure out how to program this thing without having a 2.00mm ISP connector, I might have a half-pleasant weekend ahead of me. Lots of code-recycling should speed things up a lot.

Tick tack... tick tack...

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].

Tictictictictictictic...

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