interesting project-suggest

Could anybody suggest me an interesting project for my final year engg.
My field is electronics and telecommunication and we are given a whole year to prepare the project.

meaby making digital audio transfer ower an fiberoptic line.To complicate it you cod make 2 or more audio strems gong thru one singe fiberoptic cable

I'm sure that everyone here would be immensely impressed if you managed to get a PIC18F2550 (I think) talking via USB to a VB program on a PC. And not as a HID.

If you want it to do more like control servos read temperatures, measure distance, acceleration etc then I can help with all of that stuff.

HTH

Mike.
