    OPTOCOUPLERS

    hi audioguru! you rightly said it couples the signals through a beam of light.Actually a phototransistor is switched on.But do you know that why is the transistor not damaged by high current  on motor side.(i take the motor computer example u gave) reply soon how could an electronic device like...

    OPTOCOUPLERS

    hi audioguru! that means optocouplers are basically high current filters(not exactly!) which prevent low rating devices from getting damaged by high current. prateek

    Cleaning the CCD sensor of a digital camera

    hi dido! i too have an experience with propanol, not only digital camera,u can use it for cleaning tape recorder and VCR heads,almost all electronic systems.Even if you dont get it easily,i guess any volatile liquid will do the job like ethanol,petrol,ether.Mind you, i have my personal...

    How do I start off for a Robot

    hi trigger! by the pentium processor i simply mean not only the processor chip but a desktop computer as a whole. i mean SUMIT can use the computers ports for data transfer and handshake signals for his motor(stepper preferably) just as u connect any device to ur PC like a printer or scanner or...

    How do I start off for a Robot

    hi sumit! processors like 8085 and 8086 are atleast according to me not sufficient enough for an efficient position control system. try out writing a C program in a pentium processor if you have one at your place. If u r an engineering student(as i guess) then it should not be much problem.but...

    How do I start off for a Robot

    BEFORE DEVELOPING A ROBOT! TRY OUT WRITING A SIMPLE MICROPROCESSOR (CONTROLER) PROGRAM FOR POSITION CONTROL OF A DEVICE JUST LIKE A MOTOR! ONCE YOU ARE PERFECT IN IT,ROBOT IS NOT MUCH AWAY.ACTUALLY ROBOT IS NOTHING BUT POSITION CONTROLS OF DC MOTORS!!!! PRATEEK
