Because now it is somewhat commercially available, and a lot of people (including myself) that previously weren't thinking of having this just because of the hasstle of assembling it themselves, can now consider buying a pre-made unit and play around with it.

I was thinking that it'd be REALLY GREAT if there was an easy way of making "apps" for this smart knob. Kind of like watchfaces or pebble apps. Anything to make it easier for people to play around with this. Maybe a lightweight SDK or something.

I'd be more than happy to contribute to such a thing, but doing this alone is too daunting of a task.

Side note, the 245 EUR price by Seedlabs is equally daunting :(

Your knowledge seems practical and fairly deep to me. I loved electronics so I got an electronics degree and I ended up with an irrational antipathy towards electronics since then. Got a software job instead which turned out to be a great career (compared with most of the electronics guys I know).
