HaloMods "Classic" Read-only Archive

Sorry if this is the wrong place to post this, but I couldn't find any other categories that this would fall under. This is a small project that I'm working on that I thought I'd share with you guys here, especially to see if there are any electronic hobyists or electrical engineers in the making.

So here I made a cell-phone triggered circuit for fun that basically gets triggered by a cell phone.

You call the cell phone, it rings, and sends out a signal to a circuit.


This is very useful for various things like launching a rocket (which I've already done), launching off fireworks, opening your garage door, turning on a webcam, and copious other different applications.

The phone I used was a $10 disposable phone that I got from Wallmart.

I plan to eventually possible turn this much bigger project by making a cell-phone controlled RC car. Basically you call the phone attached to the car which utilizes a PIC 2 microprocessor, and then you can control it with the keypad of the phone that called it.

Note:
You can ignore the piece of paper in the background, I posted this on my home forum and I just wanted to prove that it was made by me, by no means am I trying to advertise the forum.

That's pretty cool I suppose. I loved playing with those boards in my electrician class.

The Applications of such things have already been put into use. In Iraq, a lot of IEDs use the same principal to the letter using cell phones as remote detonators.

I noticed in the video that it appears the output is not a stable pulse is there anyway to make the pulse one long stable pulse?

Yes, but it would be much more complicated and for his uses, unnecessary.

But do people open garage doors with cell phones in Iraq? I think not.
Anyway yeah, this is pretty neat, I would like to see a video of something a bit more practical, for example the rocket.

My college learning community did this last Thursday and here is the video.
You can skip to about 3:45 for the launch

You just add the positive terminal from the phone into a gate of a thyristor, and then have the anode & cathode be connected to a external power source, such as a 9V battery.

Then the LED will stay lit, even once you hang up.

Pretty neat. Reminds me of the Schwarzenegger movie Collateral Damage.

Lol, that was a question in the exam I just did.

Depends whether you want a bistable or not. I'd guess a relay and diode should do it.
