making stuff

allright, there may not be an answer to this but, i really want to make some type of instrument, i dont think it will be a guitar, but it will be close. the reason i say that is because i cant afford all the tools that a nessesary for an actual guitar. does any one have any wiring information and or electronic information on making sounds come out of objects? i dont even know if i am asking the right questions. but i want it to not cost a lot of money.

I always fancied making a bongo drum, but never got round to it, and not sure how to ?
