Tactical Tic Tacs or Tic Tac Tech
(What's enticingly cheap, ingieniuosly deadly, and fits in a tic-tac box?)

DISCLAIMER: Yeah, this is one of those that you probably SHOULD NOT try to build and I deffinatly would never condone the construction or more importantly USE of such devices that are mentioned here. Now that I am aleviated of my ethical responsibilities, let's move on to the fun stuff.

Antipersonel Fragmentation Grenade

This is a neat concept which I have ever so recently stumbled across. After the solution to the Detonator Project fell in my lap, a whole new world of possibilities has been awakened. I have devised a small electrical circuit which will fit easilly into a tic-tac box with room to spare that may allow for the timed detonation of explosive material. Much testing needs to be done and I need to draw the schematic so everyone can see the what I am describing but this will definatly be a fun project for the kiddies. Theoretically, you will need an empty tic-tac box, a capacitor, a resistor, a diode, an SCR or Silicon Controlled Rectifier(it sounds more impressive than it is), a few of those tiny lithium batteries which total to about 9V, explosive material (I envision ammonium nitrate and diesel fuel), a tiny tuft of steel wool, a bunch of BB's, masking tape, and some hotglue.

Ok, I finally drew a crude schematic.

The above shematic is a rough concept shematic that doesn't represent the values of the components which should be used. I may post those once I test them. The 's' is for steel wool and is not a standard schematic symbol in case your an idiot or know nothing about schematics in which case you probably didn't care. By the way, if you know nothing of schematics the you can go to http://library.thinkquest.org/10784/circuit_symbols.html and find a pictoral glossary though it may not help you if you don't know anything about electronics so I will explain a bit.

Electrical current always trys to find the least resistive path from the voltage source to ground. On power, the SCR initially fully resists current flow. Current can only flow through the potentiometer. Beyond that, the uncharged electolytic capacitor is a short circuit to ground taking all current which flows to it. As it charges, it begins to impede current flow. The voltage potential between its positive lead and ground grows. In fact, it reaches 63.2% of the supply voltage t seconds where t = resistance(ohms) * capacitance(farads). In this case, lets imagine the pot is has a max of 10Mohm and the cap is 10uf. That would give the the that part of the circuit 0 - 100 seconds (depending on the value of the pot which you set when you use the device) for the voltage potential to reach 63.2% of the assumed 9V supply or about 5.6V. The zenner diode is set in reverse bias which means current can not flow through it until the voltage potential across it is a certain value. 5.6V is a standard value which is convenient for this situation. Upon reaching this threshold at the preprogrammed time, current passes through and activates the SCR. The SCR then provides a short circuit from voltage supply to ground through the steel wool igniting it instantly.

All of these parts can fit in the bottom of a tic-tac box. If you needed any more space, you could use a resistor with a static value instead of a pot. This would also make it cheaper and more reliable. I envision lithium coin cells as the power source but I can imagine a cap of sufficient magnnitude could store the charge required to ignite the steel wool. The circuit is so simple, the leads of the components can be soldered directly without a circuit board. The circuit should be sealed air tight with epoxy or hotglue since it will be in the same chamber as the explosive material. Four wires should protrude from the circuit. Two for a switch which will probably be a spring contact mechanism with a nonconductive tab as a pin between the contacts so that, when you pull the tab, the contacts come together and close the circuit. Two more wires to connect the steel wool. The whole mess should somehow be fastened to the top of the tic tac box so that the tab, and perhaps the pot, can be exposed by flicking the pop top. The remaining space should be filled with explosive compound. I was envisioning ammonium nitrate and diesel fuel but I really don't know what would work best without any testing. Simply put, these are the most obtainable substances I know of and it seems reasonable. With the compound and circuitry installed, seal the box air tight with some kind of glue. There, its all ready to explode but an explosion of such a small magnitude only equivalent to a couple of m80s is not going to do much in the ways of anti personel. In any low power destructive explosion, the shraptnel is the most dangerous part. With glue and some newspaper, make a pocket which surrounds the box. Fill the pocket with BBs and seal it at the top. I would then wrap masking tape around the whole thing to protect it from tears. Now its done.

As I have stated before, I have never built such a device (yet) and I only would for the sake of theoretical testing. Therefore, I do not by any means gaurentee any of this information and, also, i will not be responsible for your stupidity and medical and arrest record if you attempt to build and actually use this or any device which I post in this wiki.

Have fun :)

I will have more info on this later
