(So as not to drag one of those threads too far off topic...

)
You are studying electrical engineering? Computer engineering? Well, that's very cool. I'm sure that with your background in analog/audio stuff, you'll rocket right through your digital coursework. Microcontrollers are a lot of fun. They allow software guys like me to claim we know something about electronics!
I do a bit of Tesla coil building on the side, but that's about it for the analog stuff! That said, I have an enormous collection of old radio valves, and hope one day to make something interesting with them.
All the best!
