Well I just made a tubular headphone amp, so I don't need another one, but my school (graduate EE) has an open lab (if you got the credetials) with tons of penny parts and, drumroll, a CNC rapid prototyping machine complete with stacks of blank board.

I'm getting trained to use it and need an project for practice, which means I need a schematic for some circuit that will fit on a smallish sized board.

I'm using my receiver's onboard phono input, but someday I might get an amp that doesn't have one, so I guess a phono preamp would be a good project, possibly a tube one if it uses cheap and available tewbage. I think my Starving Student amp is pretty cool, so I'm down with the tubes, but a very high quality SS design would be cool too. Or any other ideas. If I had a need for a speaker xover, that size project would be ideal.

EE Grad student and you're using "tubular" and "tewbage." Hint: don't use these terms during a job interview.

Have you considered anything digital? Does it have to be A/V related? I built a killer digital clock just for giggles that fits in well with all the high-tech home theater gear:
