    catcam project!

    http://optronik.tripod.com/cgi-bin/loader.pl?pe_catcam.htm heres a fun project that i think could progress a lot if it was added here at electronics lab id like to do it, but i have no idea how to start programming microcontrolers my goal here would be to rework this project to be easier, with...

    Electronic Gun !!!!!!!!!

    ha funny story speaking of capacitors, though, couldnt you charge a ceramic capacitor with a 9v so that it is charged up beyond 9vs and then fire? just considering that you dont really want to fire that rapidly. or you could have a couple of capacitors charging up while you werent using it, and...

    The Oscilator projects

    okay, im not asking you anymore, but ive tried a 2n4922 (http://www.onsemi.com/pub/Collateral/2N4921-D.PDF) and a 2n6037 http://pdf1.alldatasheet.com/datasheet-pdf/view/21704/STMICROELECTRONICS/2N6037.html and i cant get it to work. i also used: 1k pot 9v battery 1uf 50v electrolytic capacitor...

    The Oscilator projects

    yaay! i wish i had a lab what transistor did you use? i was thinking of using mj9001 or 9000 or 2n9000 i cant remember, obviously but something from motorola thats one of the round ones, and i think its 40v npn and darlington supposedly used for switching applications do you have any idea if...

    The Oscilator projects

    ah. i see. well, i might try some anyways, considering i get them all for 75cents at axman ill try any other transistors i can get for cheap there, and update this page with which work. or maybe i could update the project? does anyone know how i might do that? anyways, thanks

    The Oscilator projects

    thanks! but what about the transistors as far as darlingtons? what does anyone think a darlington npn might change in the output?

    The Oscilator projects

    i'd like to know a lot of stuff about some of the audio oscillators that are projects here. i thought id just start a general discussion :D to start off, i was wondering about the kind of transistors that can be used for the reverse bias oscillator. -can you use NPN darlingtons? and were can you...

    synthesizer problems

    drawing it would be tedious, but a good way if your more computery, you can do it in paint either way, id like to see it, because ive been looking for a simple audio oscillator cicuit myself

    which amp to build?

    thanks! at the time i was looking around for schematics, those were the only two i could find that seemed right.

    which amp to build?

    oh, and also, does anyone know anything about the people who designed these amps? would it be helpful to contact them? or do they only speak russian or something?

    which amp to build?

    here are 2 amps that i am thinking of building: http://www.electronics-lab.com/projects/audio/017/index.html http://www.electronics-lab.com/projects/audio/005/index.html which should i build? i am aware that the first has some errors in the schematic and the power supply. i also probably need...

    How does one measure frequency response?

    how do you measure it in speakers? can you just get a bunch of tones in sound files that are completely one frequency? should i try and find some of these? or should i just play notes on a sawtooth synth on my keyboard until the speaker wont play them? and on a different note, how are capacitors...

    weirdest speaker yet

    i think i understand it now! the signal is transfered into varying amounts of gas in a glass globe, so the flame gets produces more/less heat wich creates a vibration in the air with pure pressure crazy! its supposed to sound really good

    weirdest speaker yet

    i would guess most of you know how normal speakers work, with just a cone and all. but even the weirder ones still have a vibration created with a varying current going through a conductor to create a magnetic field. but i recently came across something that is very different and i have no idea...

    help me read this circuit? please?

    yes! thank you! i just wanted to make sure it wasnt some other random thing that i didnt know about. Ive just never seen it that way before.

    help me read this circuit? please?

    oh, come on. the three of you who already read this could at least say something.
