It looks that u want to make a project related to automobiles. If u want to make one other than automobile related, then I give u two ideas. Make a Solid state wind speed and direction measuring system (NO moving parts). btw Im elec engineer and live near hitec so can guide u about this. The other idea is of an MPPT solar charge controller which is HOT in market nowadays. If not interested then no prb. You must be efficient in programming (C, assembly, VB etc.). I make my own projects but my prb is that I use only analog techniques (old elec). I have less knowledge of programming.
