i have absolutley now knowledge of electronics and i'm trying to build a tach for my racing go kart(5 hp b&s methenol motor) i have some parts and if anyone knows a way to build a circuit with what i have please let me know also if you put up a schematic please explain it to me in simple people terms (aka im retarded when it comes to electronics i thought it was great cause after 5mins i finally figured how to get an led to light up)
ok what i have is a
1 ne555 chip
2 lm339 chips
2 7 segment leds will have 2 more after i tear apart my old cb radio
4 zener diodes and a bunch of resistors from a circuit kit my younger brother got and never put together
also have some capacitors
i have a bread board to try circuit out on and a board from radio shack to put working circuit on i need to be able to measure from 100-8500 or 10000 rpm any help is greatly appreciated
also im not sure i posted this in the right forum if not could one of the admins please move it to where it belongs thanks
