  1. Can i use dc motor from car window wiper with PWM to run slow revolution disco mirror ball. I already have schematic with 4 MosFETs. And which MosFETs its best to use (How many AMPERS).
    P.S.
    Can you help to make a stepp motor which respond on sound (you know i mean: Signal  comes and stepper start runnin' on one direction, signal comes again stepper direction changes on oposit direction) but not to use microcontrollelr or PC.

  2. I wanna build the radio remote control for my room (U know lights, window, door, etc.) The main problem is to find a proper parts for this project, cuz i live in crap country(Serbia)and i cant find the right parts only elementary components. I saw on the internet allready builded radio receiver and transmiter (Rx, Tx) and i saw allready made encoders and decoders (such as HT12E, HT12D). But i cant buy 'em cuz shops dont got 'em. So if you can help to build a Radio Receiver, Transmiter, Encoder & Decoder (from 4017) from a basic components. I need at least 4 commands. There is no problem at all to make a two remote controler if needed.

  3. I have made a electronic door locker and opener and i need a delay timer for the opener for about 5-10 seconds. timer will be operated by the REGULAR SWITCH ON-OFF (NOT TASTER) which be pressed about 10 times a day, that mean i need delay timer which respond when i turn the switch ON it should power on relay and starts to counting, and when the time is up it should power off the relay and wait to i turn it off and on (same process, over and over...).
    plEase hElp!!

    P.S.
    i made standard delay timer but it have to be starts by taster and realased immidietly! (only when the taster is realased he starts to count)
