    How to test buzzer

    Yeh id say its not a normal buzzer looking at that code, it would be a milliseconds I think if its the same as timeGetTime() in c++ windows code.

    How to test buzzer

    A buzzer that needs an external oscillator isnt a buzzer, its a speaker.

    I made a 4cmx4cm 33 microfarad capacitor!

    I tried to do another demo to show u guys, and it was blipping again, and it measured even more. But its just falling apart in my hands, and the blip wasnt showing through the camera so I gave up... I need to rethink the way im going to make something a little more permanent, then ill be...

    I made a 4cmx4cm 33 microfarad capacitor!

    Thats right 33 microfarads, and I got it to pulse an led for proof! I made it with copper tape, putting down some glue stick, then put a lining of glycerine down. It would be better without the glue, but the glycerine beads against the metal so it doesnt make a good enough separation. Getting...

    electrical delay line attempt

    I don't know what you guys problem is... cant even be yourself these days.

    electrical delay line attempt

    Thanks for the input. I want to make a memory line with it for a home made computer. Heres a picture of a THZ oscillator. I wonder whats inside it...

    Weird Voltage divider issue

    Id say it would be R32 that is not connected, by what you said what was happening.

    electrical delay line attempt

    I'm into off grid living, but I haven't made it out of my flat yet! :) Why delay line memory? I think maybe it could be as good as other types of memory, and the cool thing its more hacker friendly in a lot of ways. Also I want to make a delay line memory based computer, I'm diving in a little...

    electrical delay line attempt

    Yeh thats what I meant. So how do transistors even deal with super high frequency low wavelength signals - do they end up just acting like low pass filters? =) Thanks for your patience.

    electrical delay line attempt

    Ive got a question, im confused. I read on the internet the wavelength of a terrahert down a copper wire at 21 degrees celcius is 1 mm - is this right? or is it way off. <edit> ok i think ive got it now. if electricity goes 17,700,000,000 cm/s i go 3,540 cm every 5 millionths of a...

    electrical delay line attempt

    Thanks for the reply. ///////////// WRONG ////////////// EDIT////////////////////////////////////// Your calculation puts it at 29,411 hz. so thats heaps different than my estimate, I think that im the one thats wrong tho. (I'd prefer it to be lower hz in this case, then the wire doesnt...

    Battery Consumption

    Batteries are inherently dangerous, but ppl have 2000 watts going into their house every day and it seems to be safe as long as u treat it the right way. Id say in general the more amp hours in the batteries, the more dangerous they are - the same as compressed air. But I think you would be...

    Battery Consumption

    Give yourself more than you need, or do an experiment to see how long the batteries actually last.

    Battery Consumption

    a) I guess so, but you meant 10 times longer, because there is 2 batteries. if you had 20 AA 2000mAh batteries in parallel then it would be the same. b) I heard (its maybe not true.) if you make sure you recharge the batteries consistently and never let them get more than half empty the...

    electrical delay line attempt

    Heres a mouse drawn schematic of a delay line design. This probably doesnt work! I havent tested it yet but its what im currently up to, I havent got the 60 metres of wire spooling I need for it, and im worried that i need to phase invert the magnetic field or itll induct into itself...

    Toggle between 2 LEDs on separate circuits in the same circuit?

    I dont know if itll work, but its very neat and cool lookin' :) Just takes practice and you keep getting better, then you can handle more and more complex machines.

    Taking Requests

    I liked it (the flamenco stuff), sounds great thru an electric!

    Unveiling of the pedal

    Yep I hear it 2. Is it a room recording?
