The infrared anti-tank and bb hit dedection idea for vehicles

[Auhydride]

Since my last thread was trashed, aquamarine told me to post it again lol.
Heres what i want to do:
I want to make an anti-tank replica, maybe something techie, like the javelin, M47 Dragon or spike.
Install infrared laser tagging system to the launcher and the target vehicle.
Install some effects, maybe cartridges that are filled with dry air and baby powder and a solenoid valve for the launcher, so you would reload the cartridge to shoot again and will also reload the effects, and a small fog machine for the target with flickering flame lights (in movies in order to make fire effects, there are circuits that make halogen lights flicker as if it's a flame, hide this in some smoke and you have pretty neat effects)
Also i'm planning to work on microphone/piezo based hit dedection for BBs, these will work like the guitar pick-ups, but will have a high treshold so it will just dedect the BBs. Similiar systems were made but they would dedect other stuff activating the system. But i'm planning to install them to fake gas tanks on the jeep and sides of the ATV, to make weak spots. Also hard plastic plates that will be attached around the engine compartment. And make the circuit disable the vehicle and pop smokes only if it gets shot like 10-15 times in 10 seconds. So you will need a good burst of bullets to disable the car, which can prevent accidental disabling because of rocks and plants hitting the gas tank, since they won't be loud enough or repeat at least 10 times in 10 seconds. And if something really hits the gas tank that often, there is something wrong with it's location.
Anyway these are just ideas that i shared with a few electronic guys, they all think it wouldn't be too hard to build them. Aquamarine told me there are good electronic experts on the forums so any help would be appreciated.
If you ask why i just don't use the honor system, well, we will launch the first airsoft games over here, and in order to attract some people, we need to attract the media, and media loves smokes and fires and loud bangs .

For the laser tagging one, i'm waiting for a friend to make the circuits and it might take time to get the whole thing working, but piezo/microphone idea is really simple to use at a prototype.
I'm sure i saw ready to use kits that turn lights on and off when you clap, using them at a higher treshhold might do the trick. Rest would be a circuit that would count the hits and act.
If i don't get lazy and buy some sound activated light circuits from the electronic markets tomorrow, i may post how such thing might work. If it doesn't work i will need to get similiar circuits custom built.

Heres a system that MIGHT be using piezos to dedect BB sounds

But no information given at all, it can't be "pressure sensitive" stuff since that wouldn't be that easy to build.

Check out the receivers and optics, those stuff have long range and receivers pick signals really nice, also hidden in neatly build domes.

ROFL, do a Dragon. If the police kick down your door, just explain that no terrorist in their right mind would go through the trouble of reproducing one of the most impractical anti-tank systems ever.

[Auhydride]

If there are any replica kits available to purchase it would be great, or just some diagrams

Google image search is your best friend.

It looks like it was built out of foam
Nice site, but i don't think army ever released the technical drawings of it, those are illustrations, it's tricky to build something from those.

Email the DoD and tell them you'd like to order the blueprints for a Javelin...

Just say you're the leader of a oil rich country, and you're fearful of being invaded...

Haha this one reminded me of battlefield 2142, square shaped design is so manly, maybe i can build something like this instead? Since noone would know the original design, it wouldn't be a problem if it's inaccurate lol.
And since it looks a bit high tech, people wouldn't mind the never existing rocket.

Tricky, but you don't have to get it absolutely right. It's not like someone will be measuring your prop with a ruler.

You can always start small and do LAWs or Carl Gs.

It'll be a measuring tape...

And I wish (regardless of what he makes) we'd be able to see it in person...

[Auhydride]

Problem about law, everyone knows it, and the laser tagging one can have nice features like "Locked on" and 4-5 second timer before locking on the target (the target will have infrared beacons on it next to the receivers that the launcher can dedect, if an infrared led without any optics can be dedected from at least 30-50 meters there can be a "lock on" feature) so it might be necessary to add some electronics and small leds to the launcher.
Anyway if i get the system working i will try to get any kind of launcher that can run it.

[Gunk]

Can you work in a random "miss" feature? Or countermeasures?

[Auhydride]

There can be a countermeasure like there was in battlefield 2 (most of these ideas are inspired from random games) the launcher can transmit an infrared signal all the time, that would set off an alam in the target vehichle when the launcher is pointed at it. But without any lock on timing, it would be hard to get out of range or vehicle before vehicle goes pop. But with a timer and "locked on" alarm, the driver might be able to get away from the vehicle or drive behind a tree.
Also thats the reason why only qualified people will be able to drive, someone that is new on an ATV can easily panic when locked on and run over someone.

[Gunk]

Or mysteriously slip into third gear, run over a big rock, loose control and smash through a tree, having that tree come down on said riders head and knocking him unconcious...

Still don't know how that happened...

[Auhydride]

Anyway if anyone can give me some help it would be great. Especially with the circuits. I'm studying industrial designing so i'm okay at designs and building replicas, but i fail horribly at electronics.
