- The idea for this came one day, when i was sitting in an electronics class,
- and we were supposed to be making some alarm thingy, which would be set of by
- crossing through a light beam. It hit me, that this item had a much better
- potential as a handy device in the home militants arsenal of improvised
- munitions. It offered several things that physical tripwires are limited by.
- What the device does is, it stays dormant until it is deprived of light
- (by someone crossing the light path) When it doesn't get light, it crosses over
- into a secondary circuit, which has an alarm or in our case explosives attached.
- So there you go, school isn't a total waste of time is it, and the better thing
- about this was, we were being given all the parts i needed to make it...;) which
- lets face it is a hell of a lot better than paying for them, and much easier
- than acquiring them through illegitemate means.
-
- The device has many uses. I've called it a tripwire, because thats what i
- thought it would be best as at first. But it can also be used as an alarm, or a
- cross between, where when the alarm goes off, so does the explosives....that
- would be quite alarming (bad pun) Ther good part about it is, its simple and
- easy, and relatively cheap. I'm going to provide two systems, the only
- differance will be the addition of a relay, which ups the cost by about $5.

- The parts can all be bought at most electronics stores. Avoid Dick Smith and
- Tandy, coz there just too commercial. I recommend Jay Car Electronics. All up
- the parts should only cost a couple of dollars, but the relay will be about $5,
- but it does make the circuit much better.
-
- I'm no good at scematics, so i've done you a VGA of the wiring diagram, so just
- copy that. For the cheaper style, just leave of the resistor, and have you
- explosive charge hoocked up to those two wires. (note- i havn't tried it
- without a relay, so i can't guarantee that it will work, however in theory it
- should, but it won't be as stable)
-
- The hardest part about this circuit will be the light source, people are going
- to see a torch beam focused on the system, i recommend, a bright Red LED, you
- can adjust the sensitivity of the system, by turning the trimpot. Another
- variation on the circuit would be to switch the LDR (light dependant resistor),
- with a LRR (light resistant resistor) so that as soon as light gets on the
- circuit, it is activated. Good for destroying a room, when someone enters and
- turns on a light.
-
- Thats really about it from me, you should be able to build it simply, off the
- diagram, if you have any problems contact me at Neural Hijack.
