It is awesome to see all the comments in this thread recommending some form of embedded programming as a side project. I strongly recommend it too. Here's my own fun embedded programming project... it's been 5 years now, so I should really do something like this again: https://foundrytechnologies.com/relay.php https://foundrytechnologies.com/relay.php It didn't too well commercially, perhaps because the 3d-printed case I designed for it in looked a bit cheap. But the embedded coding was very fun, as well as putting all the pieces together (embedded coding, website & web app, PCB design, CAD and 3d-printing were all involved). I did sell a few units, and shipped them worldwide. I still see them checking in with the server for updates every 5 minutes from around the world, and there's about half a dozen working around my house today, including one outside by the front door bell. That one's been exposed to the Texas elements for 5 years now and hasn't missed a beat, except that it needed a new case last year to keep it looking fresh.
