I would like to make my own speed controllers.Starting small
though,they would only need to controll RC car motors,i think there
7.2v motors.Can i make some without having to program any chips as i
dont have the equipment to do so.If i can make some could someone
point me in the direction of a web site that has plans to make some
as all the sites i find need programmed chips.

I would also like to make a mixer so i could have to motors with a
speed controller each,but as again the only plans for these i can
find need a programed chip.


Thanks fo any help.
