  7. Correct way to Measure Power Supply Amperage

    HI MHz
    FOR DEVICE RATINGS!
    always connect a moderately high resistance in series with the device and a low resistance ammeter too in series.U should not use too low resistance or a device with low input resistance(this may load your supply)
    nor u should connect very high resistance otherwise source wont supply the current at all.So optimal choice is made b/w the too.reply soon about results!

    hi steven!
    actually i am looking forward for a combination of hardware and software for IC tester.i.e what i posess is an IC say 7400.and a computer pentium 4 processor.How
    do i proceed?
    I can write the software for it myself too but atleast i should know the h/w compatibilities!!any help from anyone?

    hi birdbird!
    what i can make out of it is that your software takes in your sound only and displays it on your screen(the word u spoke)but there would be some channel along which your voice is flowing!
    may it be a computer port or a peripheral device like a microphone,but i again revert to the same point.u can identify male and female voice only with its frequency and nothing else.Female voice is generally of higher frequency.
    How are u communicating your voice to computer?and how is it converting to text back?

    hi birdbird!
    your project seems to be interesting but the thing to know is that why is your system responding to a few words only.I saw a similar project on another site(i cannot recall its name),i have seen the same project in  a book on artificial intelligence. All sources say that the only factor to distinguish any 2 types of voices is their wavelength.But i am surprised why is your software responding to a few words,can i have the circuit for your project?Actually i wish to see the code(it must be a digital code)for the voice which you are sending through a computer port into your MATLAB platform.Awaiting early reply!

    hi audioguru!
    the breadboard u have shown is exactly the same i have seen here.in this
    5 slots in a column are shorted i guess.But in india i have seen boards with one component side and one solder side(not a PCB).But just like  a PCB.
    WE HAVE SMALL SLOTS OF COPPER AROUND ON SOLDER SIDE.THEY CALL IT ZERO PURPOSE OR GENERAL PURPOSE PCB.SOME DEALERS CALL IT BREADBORD TOO!!!!
    THATS WHY I WAS CONFUSED.... ;)

    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 a small signal transistor bear such high
    current?

    hi everybody!
    actually i wish 2 know the reason behind using so many buses in a computer .why not a single bus for all types of communication.like for example,
    why to connect printer and digital camera on different buses or ports?
