    transistor base load

    heres 100 meters. need 135,000 of them then youll get 135k. :) bit pricey... https://www.ebay.com.au/itm/100m-0-2mm-Red-Magnet-Wire-Enameled-Copper-Wire-Round-Magnetic-Coil-Roll-/312597173080

    transistor base load

    I wonder how big a magnet wire spool is thats 135km!

    transistor base load

    A faster oscillator would be nice. But the transistors I have on supply are probably average switching speed. (not that ive tried to use them much.) If only an oscillator would work without one. I have an oscillator without an amp, but its dieing off, its not making much of a round trip.

    transistor base load

    I was going to make a delay line memory with it, for a delay line computer. but your average 20 megahert transistors make it not very good an option, I compute the pulses down the line are way too thick to make it worthwhile, it would be about 500 metres per pulse, not very good.

    transistor base load

    If you have a large spool of magnet wire, and you get both ends of it free some how, you might get a readable delay out of that?

    transistor base load

    woah thanks for responses! Sorry I dont mean a second, I meant a 2000th of a second - but it is still very long. I was going to print it out with my 3d printer, a big long zigzagging volumetric tunnel, and fill it up with water or conductive paint. But that would mean id have to use a bad...

    Step up circuit 5 volt dc to (72 ~90 volt )

    What troubles are you having in designing it yourself? You want 20x the voltage. A circuit would be a voltage doubler. But u could just use a 20x transformer and not really have a circuit, and it would do the job, but I guess youll need to oscillate the input maybe, to get ac. I have a...

    transistor base load

    Have you ever put a 100k resistor before the base of a transistor before? yes or no.

    transistor base load

    [mod edit: Image not appropriate -> deleted] Given a practical amount of power, is 100k too much of a resistor to apply to the base of a transistor? I'm guessing it is highish, but its not too much. It still works. But would it need 2 in a cascade?

    transistor base load

    I know I said I wasn't going to say anything, but this is a technical question, I was just wondering if you can use a 100k load on a transistors base, and it could still fire. Im asking because I want to make a 1 wire 100kOhm delay line (1 full second delay) and i was wonder if the transistor...

    Just a thread of thanx

    Thanx everybody, for making things a challenge. Theres no point blabbering on about your little tricks, when everybody has tricks, and if your trick is a good one, why spread it out like a rabbit virus, when it was more special, when you kept it a secret. Machines can become a sick obsession...

    Does this video impress u guys or is it a FAIL

    I want you guys to understand, theres a possibility that resistors actually are more powerful than transistors, u just need the right topology. But the problem is you just dont believe.

    analogue memory system

    I agree with you, I do electronics like a crazy wierdo dont I... if only someone would believe me that my stuff works as good as the "normal way to do it" but... oh well, freaky-tech dudes just have to live on, by themselves, lonely, shunned by the world. If it works... doesnt matter how...

    analogue memory system

    Could be anything really, just some-one with an original circuit, maybe... with a few mistakes here and there, and maybe some conceptual flaws, but just someone showing something that isnt just replacing a capacitor in a washing machine.
