remote detonator

[Darkshadow666]

what's the best kind of electronic device for making a remote detonator? it doesn't need especially long range, just a few hundred yards. I was thinking of using parts from a garage door opener.

Yes, radio dets are sexy.. always fun to have a slick lil deal with the magic button on there, but stray rf energy makes it hard to ensure the safety of such a device. There's pulse codes, and digital for the utmost in safety but my electrical engineer friend that could actually pull that kind of shit is in school at cal tech and probably doesn't have time to teach me the way of the digital emitter and reciever.. sigh..
However, he did show me the sweet wal-mart digital watch trick.. performed by removing the back plate of said cheap watch, snipping the tiny-ass wires free from the lil disc shaped speaker in there, and soldering them to their proper place on a SCR (silicon-controlled rectifier), avail. from radio shack for a buck or two (or six if you live in BFE like me).
The component works like a relay, using a low powered pulse of electricity from the watch to close the circuit between your batteries and your firing wire and igniter, ect. He said ni-cads were the best to use because of low internal resistance or some shit but any batts that work normally would be fine. Figure it out, there's three contacts on the lil piece, one's a common ground, takes some delicate saudering! You can easily fry the piece if your not quick with the iron.. put an LED or two on there as indicator or ready lights, on/off switch, alligator clips..
NEVER fuck with it wired up, always place your rocket or "firecracker" in its target area, run the wires, set your alarm, turn the switch on, test for current with the LED or circuit tester, THEN connect the wires to the leads. Suprises no bueno. Then, hours later, with your synchronized watch, your friend is lookin at you like you're an idiot cause you're doing a silent 4 sec countdown on your fingers when...BOOOOM!! Great fun. Oh yeah make sure you turn off the hourly chime!

Stick with the garage door opener its your best option and nothing should interfere with it.

Hit man cell phone? shit try it.. problem with that for me would be patchy or no service at my best det spots! How shitty would that be? Failed dets are a special kind of letdown....pretty sucky...then the damn dud to deal with.. I'm comin around on the garage door opener though, that would be pretty fuckin cool. Just test it for interference with a real low voltage LED or maybe better a little speaker to see what kinda stray signals you may pick up. We always got pulses and crazy noise as the transmitter began to get out of range, but that was with shitty radio shack remote control car parts. Garage door never opens by itself! Try it out, I wanna know how it goes. Just dont let the absence of 30 feet of wire deprive you of any human bits.

i make and sell the remote detonaters to my friends (all of it without the secondary explosive)
and i always found the cheapest way being the garage door opener. also, instead of cellphones (which can be annoying with the contracting and the money, i used those 80's beepers, you know, the ones which beeped when someone wrote a message. they are hella cheap and getting noe to work is a matter of 20 minutes (just cut out the speaker and attach and electric matchhead to the ends). also, you can remote detonate more than one bomb at once if you send to 3 different numbers at once. another problem i had was getting enough voltage. my first ever remote det. was using a lowvolt lightbulb with the glass removed and the tungsten touching a fuse which ignited the ap xD a rrreeeaaly cheap alternative one is a my pullstring detonator (: you know those door alarms? where when the door opens these things start ringing? well they work with a magnet, and when the magnet is removed, the alarm goes off. well, i just epoxied the end with the speaker to the casing of the bomb, and got some fishing string and wound it around the other bit. so, when you jerked the string, the bomb would go off. they are the cheapest, with door alarms costing 5 quid for 4.

Sorry to post on the wrong thread, but I would suggest buying a par of disposable cell phones from walmart, and programming one to only ring when the other one calls it, and attaching a detonator to the ringer wire. It would really suck if a telemarketer blew up your explosives before they're meant to go off. And of course you should test it first, to be sure the network works, and it only rings from the correct number. To dispose of the cell phone at the detonator site, put a little thermite around it. Just take the SIM card out of the one you called with and burn it or melt it or whatever and drop the cell either in a dumpster (not yours) or one of those boxes where you donate used sell phones.

^^^^^^^^^those are some DIY remote detonators... they work ive tried some of them out. it just requires what some of us weird people call "effort". just pick one and buy what u need and ur set. theyre reusable so enjoy.

[Hetfield]

Just an idea. Ive never tried this myself, but the electronic Boxes that you used to be able to buy, the ones that turned a car with normal central locking into a car with Remote controlled central locking, could definatley give some promise.

Just thinking, there cannot be any interferance from other devices as otherwise car thefts would be well on the up. Also they usually have a decent enough range on them. Im going to try and get some schematics and work out a system to set off a blasting cap with one. Ill keep you posted!

[quizsalt]

would an electronic barbaque lighter work?

[LizzyReikoZ]

A remote car starter is a great idea, but those things run about $200 for the remote part, and I don't know what the boxes cost.

And I have absolutely no clue about the electric BBQ lighter.

[Hetfield]

Was thinking of some thing more along the lines

http://www.directcarparts.co.uk/buy-...ng-p-7946.html

UK £69.99

At a rough guess that would be at about $100 USD

Still looking for a schematic, i'll keep you posted

[LizzyReikoZ]

I think something like that would work unless you're really far away. But a battery pack and a detonator on the box thing would be almost foolproof.

Take your meds CPL youve lost touch w/reality.Logically is there any need for me to post anonymously?Or do you crave enemys so badly your mind manufactures them for you now?

Seriously here something like cellphones and garage door openers would still be effective except for the Odd stray signal.(No radios on in a blasting area?Youve all seen the signs!?)
Iraq however the US is fielding more and more complex countermeasures that defeat these sorts of things by prematurely detonating them or jamming signals.

Rather me posting a specific source lets all use our little keybords and do a search,just for laughs lets title the search "IED countermeasures" or a variant theroff.As far as complexity just as there are simple cookbook style imp exlosives manufacture the same is true of cell phone modification etc distributed by RAGHEADS via the internet.

Seriously CPL, take your meds i know you dont like how they make you feel but its the only way to maintain your grip. Concerned,grndpndr

i'm pretty saavy with electronics. this is the first I read about using garage door openers
just how would you go about that, If someone would like to explain. appreciate it
what do you put on your explosive device, that will trigger detonation.
and will thry work wireless also?

[Misanthropy]

I'm thinking an RF receiver to serial register to AND/OR gates configured to pass a certain number to trigger SRC w/ NiCad batteries (low internal resistance, as stated) should make a good wireless detonator, no? All easily vaporized except the batteries.... maybe Li polymer cell..

Blast out the right serial code for a blast of kinetic release...

A friend says this:

"your standard carbon zinc battery.(Eveready) has plenty of short circuit amps. even more than a Nicad. Also Super Capacitors are available now with very low leakage rates(relatively speaking) and could hold up a charge for several days. They have practically zero impedance and can discharge all their energy in a blinding flash lasting less than a microsecond... Good enough ideas?"
