    Reversing polarity through signal from mouse switch

    Dont you know what an oscillator is?

    Reversing polarity through signal from mouse switch

    If you ignore the switches completely, any oscillator should work here as well, if you get it the right frequency, but you probably could involve the switches with the oscillator as well to make it not go out of synch.

    Lessons Learned and When the Chips Are Down

    1. Is my understanding correct? I don't know, cause I cant read that circuit myself either. =) 2. Capacitors only release energy if they have a loop provided for them to release on. If I look at the provided circuit I see heaps of ground connects the capacitors will be constantly...

    new original voltage doubler circuit

    The resistors ohmage can be anything, 10ohms all the way to 10,000 ohms probably works, as long as your consistent. It will all produce the ripple. The first cap has the least resistance, but the rest are all at least "bare ended" on the negative side, so they follow suit just like the...

    new original voltage doubler circuit

    It uses varying voltage division to charge the capacitors one at a time. The first empty capacitor in the chain gets the majority of the current until it fills, then the next capacitor takes over. Then the capacitors are charged to the battery volts, and discharged in series for times x volts...

    new original voltage doubler circuit

    The caps need to be rated at the voltage post multiplication, but they can be any farad - the lower the farads the less amps in the plasma and the more frequent it is. The resistors can be very low ohmage, and only the resistors on the blue wire limit the current on the output - the charge...

    Its just a wire, excuse the dodgy drawing. :)

    new original voltage doubler circuit

    Yes indeed voltage doublers have been around since the birth of electronics right? But my method is slightly different, and it runs off a dc source, but it has a spark gap on the high voltage line, so its like an oscillator anyway. And I think (but I havent tested it yet.) I can run mine...

    CPU out of logic gates

    Thats a great system you have there, would be cool watching it run a simple game on an led matrix like maybe tetris or pong. Im not into the standard way to make a cpu, I prefer something cacheless maybe using circular access memory (has to be accessed in order, so its good for program...

    when you learnt and become pro, did anything amazing happen?

    Oppsy... I have to first get something out of the way... Looks ive caused a bit of a hoax. I was only talking about the nest thing metaphorically, im actually 37, im not a kid, but i mean "IN electronics" i am - Thats what I meant, sorry about the miscommunication. My explanation skills...

    when you learnt and become pro, did anything amazing happen?

    Thanks for kind reply, thats really cool... sounds a bit scary to me to go on an adventure like that, but I guess thats what youthful bravery is for, to dive you into new places. Of the equipment you worked on, can u draw up a communication radio schematic yourself now? Im kissing being an...

    god man, all those beautiful tools and too sick to work. you have my sympathy. poor guy.

    when you learnt and become pro, did anything amazing happen?

    I was just wondering, because I feel like im nearly ready to fledge my wings and take off from my parents nest. (if i was a bird, and im not.) What was it like for some of the more knowledgeable guys/gallahs here - any huge life changing experience?

    Keep fighting. It may be paranormal whats happening to you. Im also getting attacked, its a sign that u are a powerful person, that god or whatever monkey upstairs whats to put you away!!!

    how to make the circuit of a wall e robot

    Robots are all kinda the same... but in general you can include and disclude different things. Mostly they are just a bunch of brackets connecting motors together, and the circuit is comprised of sensors talking to cpu talking to the motor drivers, absolute position feedback helps make it...

    Help with circuit design

    Is this just an aesthetic flaw? - as in its only visual the error - if so just invert it - theres plenty of ways to do that, im not sure of the method that ppl feel comfortable around here.

    entrepreneurs and companies that work in the field of electrical engineering

    Hmm, I always thought "analogue" was the important word in the industry, not that I know what other people are doing. Find analogues between all pressure mediums, like electronics, hydrolics and pneumatics, even mechanical logic - ring a bell with each other, and can help you get your machine...
