    Woo-Woo passive amplification using an lc oscillator

    So if you set up an lc oscillator with a side route, and a capacitor with a diode, you will collect the compressions, and u should end up with more than 100% after the osc has settled! what do u think?

    What thermal fuse do I need.

    The amps has to do with the rest of the circuit as well, I think you measure the resistance- and that will tell you how much amps goes through. (I think thats partially wrong tho...)

    Can someone show me how to install a digital/mechanical counter on a device?

    (im just winging it here) It would take so much power from the thing you want to count, and it would be best to not take too much current from where ur hacking in to it, or you might disturb the circuit (like a multimeter), but maybe that doesnt matter, depends, and so much extra power to run...

    Maybe they were jealous.

    Pure Parallel does increase power requirements - but it would potentially give you sub pico-second sampling, if you handled all the other problems, which I'm not aware of yet.

    I see, I was thinking it was a current dependant input! i see now. cool. You can exchange the diodes for voltage dividers, if your short on semiconductors. :) So does that mean you just put a current divider instead of a voltage divider you get the current version!?

    Old magazine series 99 IC projects

    In the 1979 one, I see a gizmo for a bar graph, and someone needed one for his water tank not long ago. =) It works with a strange technique of dropping voltage through diodes, but I dont see how it works entirely. Its actually an ADC! but you need one bar per bit, not one bit per power of...

    Why is it PNP instead of PPN for transistors

    Did u mean you have to wait for the logic to "settle" so you dont get spurious outputs? Yep, but I wonder because "ripple" settles pretty quickly you can actually disregard the random values if you just want a direct link from in to out - the simplest form of machine, that would be. And a...

    Why is it PNP instead of PPN for transistors

    Do you still have the schematic? That would be cool. And did it have an oscillator - or was purely just I -> O? Cause if its I to O, you dont need an oscillator because you only need to change the output when the input changes, so logic actually doesnt need an oscillator every single time.

    Why is it PNP instead of PPN for transistors

    Did you ever design a computer? Im feeling pretty confident that its going to be pretty easy in the end and I wont know what I was worried about. Did u ever design an ALU? you can put one adder in, but if you put the amount of adders, one per bus bit, you can make a multiplier that runs...

    do passive rc filters have problems with 10GHz + frequencies?

    So ok, I read a bit more, and ive got a solution already, but why is it called impedance, calling it parasitic inductance says it better.

    do passive rc filters have problems with 10GHz + frequencies?

    What causes the difficulty, too much resistance? and the capacitors are too small? I only know how to make single pole filters, cause I'm only a beginner, and the maths is kinda complicated. (Ive copied alot of digital filter designers and got them to work but I didnt understand them.) I know...

    do passive rc filters have problems with 10GHz + frequencies?

    So! That must mean it DOESNT HAPPEN!!! mhahahahahahahahaha.

    do passive rc filters have problems with 10GHz + frequencies?

    Thanks for the in-depth explanation, so do even spark gap oscillators suffer from this phenomena given the same circumstance? What 2 circuits? dont you count it as 1, when the oscillator meets the logic/alu?

    plasma display

    Oh I see. but its just not as zany as doing it in the open air like a spark plug. :)

    plasma display

    But I actually mean *spark gap* as in that kind of plasma. Just the electricity in the air. Is it actually the same thing?

    do passive rc filters have problems with 10GHz + frequencies?

    I actually dont understand, its got something to do with impedance, which is due to capacitance? But in the video the engineer showed he fixed it with what looks like a voltage divider... and I dont know how that would fix it, no.

    plasma display

    Has anyone ever seen someone making a display out of spark gaps? It would be similar voltage to a neon bulb no? Would be quite spectacular.

    Why is it PNP instead of PPN for transistors

    Doesnt take many wires for it to get fiddly, programming only requires keyboard and mouse, electronics with the hands is very frustrating for everyone i'm pretty sure.

    Why is it PNP instead of PPN for transistors

    With only 3 legs on a transistor its only ABC,ACB,BAC,CBA,BCA,CAB - 6 permutations, but then you need to test all the polarities, and its fiddly as hell with all the wires going everywhere. I tried the two diodes making a transistor as well, because I saw a gif of it on the internet, and it...
