    Traffic Lights

    Amazing build, thank you for explaining the relay process in the video. That clears up a lot of confusion anyone may have. Great wire organization too! Well done!

    Traffic Lights

    It did, the circuit seems to work great! Can't wait to see the large version.

    Video doesn't work. Try uploading to Youtube and post it then?

    Help with building a star wars blaster light/sound circuit.

    If you want it as small as possible I'd suggest surface mount components but though those can be a pain to work with sometimes. You'd have to make a completely different circuit alone just to get the pre-recorded sound effect to play. A simple solution to make it last that long is to just push...

    A perfect real world application! Can't wait to see how it looks ;)

    Metal Detector

    Well I'm not sure what every component in the entire circuit does. The only reason why I assume you would ask such a thing is because this is a school assignment or something of the sort. However, I can tell you what I do know Inductor: When the metal gets close to the inductor, it causes...

    Stun Gun

    This guy has. He even tested it.

    LED Dice

    That's a good observation. I have no idea where it goes but it may not even be required since it could be a typo. My suggestion is to follow the diagram and if it doesn't work when you make it then you know something is up.

    Bike Turning Signal

    The LEDs would get dimmer as you added more, I think, but probably after a certain amount. You should be fine with 10 LEDs.

    12v motor controller

    Did the breadboard layout. Please look it over as I am 99% sure I made a mistake. This is the most complex circuit I've ever done a breadboard layout for with digital art.

    Coil in emp circuit

    That's cool, how many turns are on that thing? Any way to show a video of it working?

    Coil in emp circuit

    10-30 turn inductor coil. That's what is says on the schematic. That means that you can use ANY inductor that has 10-30 spiral wound coil.

    Flashing Railroad Lights

    Actually I just figured it out... lol. The LED was bad and I needed to make a jumper cable.

    Flashing Railroad Lights

    Built this bugger but one of the LEDs don't turn on. Anyone see a problem in my design?

    Variable resistor

    You're going to have to be more thorough in telling us as to what you're trying to do.
