This is a very cool idea. We have a project along a similar vein at HackerBoxes. Tron looks like great basic circuit education/exposure, while we're doing things more on a project level. These could even be complimentary, so some may want to subscribe to both.

Either way, please keep in touch with us over here at HackerBoxes. In order to gauge what users find more or less interesting, we definitely want to hear feedback on our boxes from all subscribers, certainly the HackerNews crowd!
