    Storing energy in Capacitors

    And here's the enclosure to put them in. RS have 15 in stock, you can have any colour as long as it's blue :)

    Which Arduino(or clone) to pick?

    Thanks shumifan50 Adam

    Which Arduino(or clone) to pick?

    What are Shields? What distance are you going to need and how much data. Can you tell us a bit more about your project. Thanks Adam

    Storing energy in Capacitors

    I think he has looked at super capacitors already. Adam

    TRANSISTOR SELECTION

    Your switch is shorting out your supply. Re-draw the circuit, would it also be possible to change the background colour to white. Thanks Adam

    My first circuit, some questions..

    I don't expect your LED will turn off. When the battery reaches 13.8 Volts power will be disconnected, then the battery voltage will resume say 12.8V and your circuit will turn on again. You need some hysteresis. Thanks Adam

    Hi everyone, new member

    Hi Canobi. Adam

    Storing energy in Capacitors

    What current are the LEDs drawing, how many LEDs do you have, how are they connected. So you want to remove the battery and let the LEDs run for a certain amount of time. Is this correct? If so how long do you want them to run for? You do know the capacitors won't increase the capacity of the...

    Multiple Input Charger Help

    I assume you meant in series, diodes only conduct one way. maybe I am not understanding where you are going to put them. Can you draw a circuit? Adam

    Multiple Input Charger Help

    A re-setable fuse like a PTC is the easiest option because you still need to charge the car so diodes wont work. Thanks Adam

    Joule Thief Is Not Working

    Thanks Steve, I never heard of that before, how does it respond to component tolerances? Adam

    Joule Thief Is Not Working

    How does it oscillate without a capacitor? Adam

    Does this switch exist!?

    Sounds like you need is a retriggerable mono-stable. I have never seen a mechanical switch with this built in, but that's not to say they don't exist. Some of the other guys might have seen one. But if you need a circuit then they are quite easy to built from electronic components. See here...

    May I tell you about my free book?

    This is a great book Steve. I have sent you a message with some comments. Thanks Adam

    May I tell you about my free book?

    I'll have a look, I might even give you some tips in return :), what's it called Steve? Cheers Adam

    That's fair enough I didn't know what they were like , I guessed which way you were heading anyway. Adam

    tinyTesla: DIY kit for beginners

    I don't see a problem with this kit, If the kit is well detailed and you are aware of the dangers of high voltages then give it a go. The dangerous part is when you became complacent about high voltages, ask some TV engineer how many shocks they have had because of complacency. Make sure you...
