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!

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?

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 ;)

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...

This guy has. He even tested it.

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.

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

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.

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

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.

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

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

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

Anyone want to make a breadboard layout and parts list for me? I'm going to be busy for the next while and won't have the time. Would greatly be appreciated, thanks! If not, I'll just do it next Saturday or later. PCB Drill Speed Controller with 555 Described here is a simple, inexpensive and...

No worries!:D

1. Thanks, I noticed this a long time ago but never got around to fixing it. I'll update that post, or make a new post, later. 2. No, look at the diagram I've made. I placed them incorrectly but noticed that I put letters above the specific pin so the person can still tell which is which. It...

Hmm, idk. I'll post other circuits I found, but they aren't fog horn circuits. Electronic horn circuit for motorcycle and electric cars Speaker motorcycles or electric cars are generally the use of electromagnetic vibration, and its interior has a set of coils. Power resulting from the magnetic...
