    Hes trying to help out.

    is an optocoupler faster rise time than a transistor?

    I dont think the speed problem is the LED, its the photovoltaic cell, you need 1ns!

    is an optocoupler faster rise time than a transistor?

    It finishes off with the direct battery connection. (You can make an oscillator with opto-couplers.)

    Has anyone here ever used a serial screen?

    It does. if youve got a 1000x1000 screen it only takes 60 megahertz to hit every pixel 60 times a second, so its easily done with one wire. If you had a 10,000x10,000 screen, then it would be 6,000 megahertz, out of the range of cheap transistors, but I guess professional ones could do it...

    Could be another optocoupler. :)

    is an optocoupler faster rise time than a transistor?

    When you want to make a gigahert oscillator, I see on the internet that transistors only rise in megahertz not gigahertz. (But that could be bulldust... oc) But I was wondering what the switching speed of optocouplers would be? It could be faster. So its an led, next to a photovoltaic cell...

    Has anyone here ever used a serial screen?

    The only need for a parallel protocol would be a high speed camera, monitors would never need it because we only see at about ~60hz. :)

    Has anyone here ever used a serial screen?

    Do you mean that you feed the graphics data in serially down a single wire?

    What the hell is a 8.5GHz Quantum Analyzer?

    Its got 64 qbits apparently. so that would be a classical state size of 18 exabits... a little unbelievable, but who the hell knows what it even is.

    What the hell is a 8.5GHz Quantum Analyzer?

    Nope, its got nothing to do with it... my computer is 100% quantum free. Quantum mechanics doesn't make much sense to me the way its explained, but it seems come to an ordinary electrical schematic the same? I need to see inside this thing.

    Speaker & Amp Impedance Question

    We mean what isnt dissipated, stays in the battery. Batteries last longer if you dont short them.

    Iwatsu ss-5711 probe suggestion

    Thanks Bertus. Sorry for hi-jacking the thread like a n00b, So at high frequencies it starts shorting to negative instead of going through the oscilloscope? Thankyou.

    Iwatsu ss-5711 probe suggestion

    What makes a 100 mhz probe a 100mhz? wouldnt any old wire do for a probe?

    motor speed controler issue

    Pots actually have 2 outputs, one the inverse of the other. (The input is in the middle.) I spose the input and output being swapped probably useful as well.

    How to make a direct current diy space heater... with solar panels?

    have you seen this before - it might interest you-> Even tho it makes more sense to make a cooler out of solar panels, cause isnt it hot outside with all the sun power?

    Signal lenght detection

    tee-hee =) P.S. is q1 and q2 a latch? - i forgot to make my explanation one, mine would just temporarily fire the led when the sound was there, but wouldnt stay on like a switch, I actually dont know how to make a transistor only latch yet, except with an led and cad sul resistor.

    Signal lenght detection

    I know a solution to this, short to a capacitor before you go to the base of the transistor, and itll act as a timer, only once the capacitor is filled will the transistor turn on. But youll have to put a 10k resistor around the cap to make sure it empties itself, and it'll only work with...

    BJT vs MOSFET for logic gates help

    But showing you the circuit would do me no good, (Im thinking your not going to like it.) youll have to think of it yourself.

    BJT vs MOSFET for logic gates help

    I cant proove it to you, it seems that you'll have to work it out yourself in your own time, but I promise u it is possible!! I could draw up the circuits, its not complicated. The logic is the easy thing, the engine that runs it (the oscillator) is harder in my opinion.
