Detonation of Double Based Smokeless Propellants/Powder Smokeless powder is also difficult to ignite. I have been working on a project to ignite it elect ...	25-2-2011 at 20:35 by: gregxy
PETN synth The easy way to create your own controller of this type is with a micro controller. For example th ...	16-2-2011 at 10:35 by: gregxy
Diving Into the World of Fulminates That method will not work. You can only make fulminates that way with mercury and silver. Che ...	6-2-2011 at 15:59 by: gregxy
EBW System Requirements The voltage you need also depends on the length of your wires. If you have hundreds of feet of wire ...	20-1-2011 at 11:20 by: gregxy

safer NG alternatives I think that most of the accidents that have occurred have been during the nitrations due to run-aw ...	18-12-2010 at 14:27 by: gregxy
Spontaneous Ignition It would also be interesting to investigate if aluminium carbide is what makes the "dark german" pow ...	9-12-2010 at 10:36 by: gregxy
Cattle prod for electric bridge wire It also depends on what you mean by initiate. A laser pointer (or one made from a CD burner) that c ...	7-12-2010 at 12:34 by: gregxy
Firearms design I have decided to design my own 9mm gun. I'm interested to know how the peak chamber pressure depe ...	30-11-2010 at 11:34 by: gregxy
There's a new sheriff in town This section on the forum really needs a "sticky" on safety. It could prevent some accidents. Plus ...	28-11-2010 at 22:40 by: gregxy
Flash powder detonation I think that the main point is that pressing (or increasing the density) should improve the performa ...	26-10-2010 at 13:17 by: gregxy
Direct electrical initiation of secondary I'll do some more experiments when I get more time, (I'm moving now so everything is in disarray). ...	20-10-2010 at 13:54 by: gregxy
Flash powder detonation One way to tell the difference between burning and detonation would be how the sample responds to pr ...	19-10-2010 at 15:09 by: gregxy
Direct electrical initiation of secondary Thanks for all the helpful references! Looking at Cooper's book, the description for the ebw fire ...	15-10-2010 at 10:26 by: gregxy
Direct electrical initiation of secondary Primary -vs- secondary is more of a contimum than a discrete state. I don't think I could ever init ...	13-10-2010 at 21:46 by: gregxy
Direct electrical initiation of secondary 60mJ did seem to be very small, although it is difficult to ignite ETN with a flame, let alone a s ...	10-10-2010 at 15:38 by: gregxy
Direct electrical initiation of secondary Wikipedia lists the amount of energy to initiate PETN as 10-60mJ, not very much energy. Disposable ...	9-10-2010 at 17:48 by: gregxy
Someone PLEASE tell me what happend.... It is an interesting question how some spontaneous decomposition could produce enough heat to detona ...	23-9-2010 at 11:07 by: gregxy
An interesting way to find H2S04 strength I did some experiments: Mixing 23g of Rooto with 23g of water (both at 32F), the temperature rea ...	20-9-2010 at 12:24 by: gregxy
An interesting way to find H2S04 strength The question often comes up of how concentrated an unknown source of H2SO4 (like Rooto) is. Densi ...	5-9-2010 at 13:41 by: gregxy
How well erythritol nitrates in HNO3/H2SO4? Pentaeurethol is probably easiest to nitrate since each -OH is attached to a CH2 resulting in less ...	28-8-2010 at 17:45 by: gregxy
Quick question on a potassium chlorate cell If you do use multiple supplies keep the outputs separate, for example if you use 12 rods tie 4 rod ...	22-8-2010 at 19:38 by: gregxy
Quick question on a potassium chlorate cell Its an interesting question. Using AC would save the cost and losses in the diode. But I suspect ...	19-8-2010 at 20:20 by: gregxy
