    BJT vs MOSFET for logic gates help

    I wouldn't trust simulators, its like trusting someone on the back of a motorbike, I'd do it in real life myself. They work good for known circuits, but if you give it anything original at all it'll stuff it up I bet. I dont know for sure, and its just a wild guess cause I havent finished my...

    Speaker & Amp Impedance Question

    Yeh ok. then how does it apply to t=rc? how come volts doesnt appear in this equation?

    Speaker & Amp Impedance Question

    I didnt understood it.

    Gpu and high power requirements.

    yes. sorry sir, i wont do it again...

    Gpu and high power requirements.

    Yes. Quantum computing is actually 99% misunderstood by everyone. If there is a real quantum computer out there, its protected by God if it exists or not because it would possibly blow up the planet, because its too powerful, and its alot devalued and taken for granted how diabolical it is...

    Speaker & Amp Impedance Question

    So thats like back emf in motors. Wouldnt the charge generated only be attracted back the opposite end of the coil of the speaker?

    Speaker & Amp Impedance Question

    Is that the electrical delay caused by the coil in the previous speaker?!?!? Nah I doubt that, that would only be in nanoseconds...

    Speaker & Amp Impedance Question

    It stays in the battery.

    Speaker & Amp Impedance Question

    Its not dissipated - isnt that when it turns into heat? But the power probably wouldnt get to the speaker, thats for sure.

    Gpu and high power requirements.

    [edit question changed] so if a single cpu takes what it takes to light 1 led. a gpu would take what it takes to light 2000 leds, if it had 2000 cores. How much power does it take to run 1 led? So its a bit of a silly question, because I bet a computer (even an analogue one) maybe could run...

    Speaker & Amp Impedance Question

    Can u add a 4 ohm resistor to the 4 ohm speaker and turn it into an 8 ohm?

    passive inverter circuit with one short pulse

    Thanks 73's de Edd, for the Ed. got the junctions in - is the cap in the right way around? :)

    passive inverter circuit with one short pulse

    If that dot isnt there on those T-Junctions in the cad program, I can guess that your right there for the simulation results. If I get my "big thing" Im going to test it out on all the simulators and see if they can take unorthodoxy. I have actually got a sim to work (In Falstad.), as you...

    passive inverter circuit with one short pulse

    looks swisher with it. :)

    passive inverter circuit with one short pulse

    thanks! I might be in luck soon... just gotta keep on screwin the components together, and im racing around doing a million diagrams, i get them all wrong so much, but im starting to get a bit more correct with the resistances and wire positions, but too early to say.

    passive inverter circuit with one short pulse

    The diverter is just an extra channel it has that activates when the capacitor is full. Im pretty sure itll be in the finished design for this thing im making, but nothings totally certain yet... every time you close the switch, you get a discharge then a recharge when u release. (so if...

    passive inverter circuit with one short pulse

    I know you guys prefer doing inverters with transistors, but this one is actually pretty good, I can actually invert half the resistance with double the resistance so it could be useful, And its actually because there is a capacitor, the charge only partially turns off, but it gives the...

    connect high power signal to oscilloscope?

    Henri Abrahams astable multivibrator

    Making an oscillator is a really successful thing to me, if you dont appreciate it, its up to you... I dont know why you wouldnt be so happy... :)

    Henri Abrahams astable multivibrator

    I think if I finally get this oscillator done, ill know enough to make my computer, the oscillator is the hardest bit in my mind. If I finally get my one finished, ill be so proud of it, itll get me right out of the dumps!!!
