Either in a string with quick/sticky match or with electric ignitors with the detonators wired in series (must be series).
Electrical would be easier and more reliable, saves the bother of making sticky/quickmatch too.
I'm guessing this is to go with the shaped charges you were asking about in the High Explosives section?

Theoretically, parallel would set them all off at once. You'd have to pump a hell of a lot of current through the curcuit though, because it would get split 20 different ways. If you wire them in series the circuit will be broken when the first detonator goes off, and you'll get very disappointing results.

well, if you would bother to read the description of the "low explosives" topic, you would see detonators goes here... i don't know why, but it does.
anyway, you could use more than one battery, say like 10 or 20 and rig a switch that closes all 20 circuts at once. you are defenetly going to need more than one battery to do this job. even if you use a car battery you still might need more than one. it also depends on the length of wire you are using. how long is the wire (collectively, altogether)?

You wouldnt happen to have some Uranium would you? Hehehe. You could tape them all together. You could have each detonator rigged with the + to the + and the - to the -. Then hook it up to a car or something with not too much juice. This should do a decent job I think. But if your working with a nuke, DONT go with black match\stickey match. If it fucks up, your out one expensive bomb. You could use also an explosive fuse.

well i think, when talking about fuses, i think 20 detonators at once demands the specific attention of electronic initiation. this is the most precise way to set things off, and this type of power needs that. as for uranium... you do not make a nuke by compressing uranium. you make a nuke by compressing plutonium to critical mass. with uranium, you have to bombard it with neutrons (i think) and this setos off a chain reaction.

Shit! I meant parallel not series, twas late such and I was tired.
Electric det, is the proper method for the job. Having to close twenty switches at once is asking for problems, just usea big switch and somehting that can provide plenty of amps (no D cells here) car battery will work but you might not want to carry it to your test site. I'd recommended a sealed lead acid battery, I've got some 12v 7ah onest hat will give about 80 amps - plenty for 20 caps.
Another option would be det. cord and just have one electric cap, or fuse cap to detonate the cord and it will do the rest. You would have to make it though, so electrical still looks like the best bet.
I think with the uranium, you can bombard it with the electrons flying off more uranium. The idea being you bring two lumps of fissionable U235 together (with explosives) andt he total mass becomes at least the critical mass. I could be wrong (again ).

well non weapons grade uranium can be easily obtained. but weapons grade is another story. and when talking about non weapons grade uranium i think you are talking about the depleted uranium shit, that should go int he IW section. anyway, like i said before, using 20 detonators demands electronic detonation. also, using more than one battery helps. (unless initiating detcord, then just one battery to detonate the tip of the cord...)

I think a possibility to set off 20 dets at the same time is to switch 20 pieces of 100 Ohm resistors parallel together (one in each detonator) Then you must load up a capacitor energy bank to aprox. 200-400 V.
For 20 resistors you must have high capacity like a few thousand µF to produce a high power impulse in each resistor.
For nukes the ignitors must have micro or nanoseconds precision. No chance to make at home.

yes they will take the shortest path until the path is broken. ie.: the ignitor is broken. then it will go to the one with the next shortest path and so on and so on until all 20 have been initiated. this would all happen in a miniscule amount of time (milliseconds most likely).

Yes, current takes the shortest way and the shortest way is through each of the 20 resistors. They have all the same resistance and so they get all the same current. The maximum power peak is more than 200W (depents on the voltage in the caps)
It is a quality of resistors that they produce an open circruit after they´re destroyed by the heat. The carbon film burns away.
So you must only have enough power in the caps and all 20 pieces go off.

What if you were to have 20 radio detanators all made exactly the same, same company (so they use the same metals in the wires and same circuitry) and then I think it would be the same enough. I just think that the main differance would be in the detonators (the time the detanators explode wont be exactly the same). If you want to blow a nuke, just use a light (or you could use a powerfull LASER (Edmond Scientific) to cause a detonation if you dont want to fuck with EXTREMELY sensitive explosives) sensitive explosive (Silver Fulminate I think, but VERY sensitive) coated base charge with some kind of surround sound lighting system.

For nukes with U-235, you compress a sphere of it with a PBX. THEN you bombard it with neutrons from a beryllium/americium alloy to start the chain reaction.
Back to the subject!
Wire the dets. in parrallel and use a high capacitance, high voltage capacitor to fire them. I've had success with a 3000uF, 350v cap. bank (20 photoflash caps. in parrallel).
This will make the ignition wires explode at VERY nearly the same time, rather than have them heat up and detonate the primary charge, which takes longer and will be less precise and will have more deviation.

Just thinking, how much current (and/or voltage) does a commercial detonator box produce? Obviously it must have some kind of capacitor to build up the charge as the generator is wound.

As for the 20 bcaps at once, it would be quite simply to be done. goto k-mart or wal-mart and get a few disposible camras with flash. i would suggest using a known brand over cheep ones, i have noticed cheep ones have less power behind the flash (but ya never know). take apart and salvage the board & cap. u can hook multiple of thoes caps up in parrell (++, --) for more power. i have taken apart an old rc car battery charger and made a little det box for electrical ignited charges, has 15 min timer or push button (user specified). and like said in an earlier message it does send a big enough charge threw the modle rocket engine igntiors to make them go off with a little pop and spars everywere blowing the wire apart. i have done that successfully with 1 photoflash cap. use the camra flash bord to charge the photoflash caps, and it will charge them in a cap bank, it just take a few seconds longer.
As for going 1 then the next then the next for the ingitors, hook all up in parrell and if u can find the right switch (i have seen them like this) that supports 10+ diffrent switches in one. if u know enough about electronics u could use one of these switches and set up the cap bank so when it is done charging, it cuts all links to eachother and to the switch so there would be an output for each cap (if your worried about power loss). you can leave all the positives tied together and have a common positive and individule grounds since power does flow from - to +.
Hope this helped solve the question, any questions plz email me.

There was an error in the above post, i am sorry my mind thinks in a wierd way so wording comes out a little funky at times.
if using 1 photoflash cap, hook them in parrell, or same if using a capbank with all going to same outputs.
if using capbank with the 10+ seg switch then hook 1 ignitor up to each output tieing all the positives together (if done that way). if you tie all + together, then there will only be 11 output connecters for 10 charges (10 negitive 1 positive). if you dont tie all + together there will be 20 outputs (10 + 10 -) and u must be shure to connect the + & - to the same cap (duh!).
if you have any questions about how to hook up the capbank etc with a charge/fire switch or any other questions plz do email me.

Why not try a det-cord as suggested earlier?
I think it is by far the most reliable system ( think of all the connections that could be less than perfect in an electrical system ).
I have recently discovered that nitroglycerine is much less sensitive than AP, just as easy to make, almost as cheap and if you were to suck it up into a thin
(2-3mm internal) hose, making sure that there where no bubbles, you would have a great det-cord. At least I think you would; as soon as the weather clears up a bit I will make some tests and bring you the results.

'Freak, he already knows WHAT he's going to set if off with, he just wanted to know HOW. It's a moot point by now, anyway. Simply out of curiosity, have you ever tried to set off a plastic explosive with a model rocket igniter? Didn't think so.

LEAVE OFF the nukes!!
Just thinking, how much current (and/or voltage) does a commercial detonator box produce? Obviously it must have some kind of capacitor to build up the charge as the generator is wound.

As for the 20 bcaps at once, it would be quite simply to be done. goto k-mart or wal-mart and get a few disposible camras with flash. i would suggest using a known brand over cheep ones, i have noticed cheep ones have less power behind the flash (but ya never know). take apart and salvage the board & cap. u can hook multiple of thoes caps up in parrell (++, --) for more power. i have taken apart an old rc car battery charger and made a little det box for electrical ignited charges, has 15 min timer or push button (user specified). and like said in an earlier message it does send a big enough charge threw the modle rocket engine igntiors to make them go off with a little pop and spars everywere blowing the wire apart. i have done that successfully with 1 photoflash cap. use the camra flash bord to charge the photoflash caps, and it will charge them in a cap bank, it just take a few seconds longer.
As for going 1 then the next then the next for the ingitors, hook all up in parrell and if u can find the right switch (i have seen them like this) that supports 10+ diffrent switches in one. if u know enough about electronics u could use one of these switches and set up the cap bank so when it is done charging, it cuts all links to eachother and to the switch so there would be an output for each cap (if your worried about power loss). you can leave all the positives tied together and have a common positive and individule grounds since power does flow from - to +.
Hope this helped solve the question, any questions plz email me.

There was an error in the above post, i am sorry my mind thinks in a wierd way so wording comes out a little funky at times.
if using 1 photoflash cap, hook them in parrell, or same if using a capbank with all going to same outputs.
if using capbank with the 10+ seg switch then hook 1 ignitor up to each output tieing all the positives together (if done that way). if you tie all + together, then there will only be 11 output connecters for 10 charges (10 negitive 1 positive). if you dont tie all + together there will be 20 outputs (10 + 10 -) and u must be shure to connect the + & - to the same cap (duh!).
if you have any questions about how to hook up the capbank etc with a charge/fire switch or any other questions plz do email me.

Why not try a det-cord as suggested earlier?
I think it is by far the most reliable system ( think of all the connections that could be less than perfect in an electrical system ).
I have recently discovered that nitroglycerine is much less sensitive than AP, just as easy to make, almost as cheap and if you were to suck it up into a thin
(2-3mm internal) hose, making sure that there where no bubbles, you would have a great det-cord. At least I think you would; as soon as the weather clears up a bit I will make some tests and bring you the results.
