I agree it is kind of an ideal, but not an unreachable one.

Doesn't a typical minigun spin a heavier barrel assembly at much higher speeds(1,000-10,000 rpm for the predator gun 3.2 HP max)? If he's only wanting 20rpm from maybe 50 pounds of plastic, 5hp seems a bit overkill to me. But it really ...

cannon freak,

I've been planning a project like this for some time. Always in the design stages, and never in the build phase :lol: As you can tell, I don't frequent these forums often, it depends on which one of my many hobbies has my attention at the time.

Here's some things I was planning ...

I know that my propane regulator gets all out of whack in the cold. I have to re-set the pressure back to nominal after every shot, and it leaks more due to the seals/parts not moving as well in the cold. Cheap regulator I guess.

I found this picture/schematic that I can understand:

http://www.coilgun.info/mark4/scr_wiring.htm

I'm assuming this is correct. I may not get a "stud" type, but it's labeled with the schematic language as well. I may have to test this and see what happens. I'll get an SCR, and rig it up to my ...

Hey GalFisk, I'm having trouble figuring out how I would wire up an SRC. My plan was to trigger it with a momentary switch to the SCR to trigger the spark, and I can't seem to find anything more than electrical theory on the SCR's and that's not too much help for me. Could you give me some pointers ...

you can use a SCR (aka thyristor) to precisely trigger a stun gun. One that will handle the voltage across the internal spark gap costs a couple of bucks at the most. It can also be controlled electronically.

I posted some ideas on spudtech a while ago about self-venting combustion chamber ...

You should install a capacitor with a lower capacitance rating.

Should have responded to this earlier. If I do this it will take less time to charge, but wouldn't it also produce a smaller--or shorter duration--spark? I guess that's not really a bad thing considering the massive spark they can ...

Did some research on this site:

http://www.emanator.demon.co.uk/bigclive/stunner.htm

Apparently the main shock is triggered by a smaller spark gap ( X shaped ) which then dumps the cap through a high voltage pulse transformer. I wonder if I can put a switch or relay on this initial spark gap to ...

frankrede, they've actually been fairly constructive with their comment so far, and anyone trying to help me out is welcome. I'm trying to find a simple solution if I can. Has anyone set up a stun gun so that it charges the cap and then waits for a signal--button push--to let the spark go? I may ...

I may do just that. I've messed around with the stun gun on the gun I have and when the button is pressed, it takes a bit for the capacitor to charge and then spark. Not long, but it's noticable. Also, if the button is held down for a bit too long, it partially charges the capacitor and when the ...

Alright I'll give a hint. I know a lot of people dream of this and plan it out in their heads, and I've been doing some planning and dreaming of my own. For a high-rate-of-fire spud gun :). I've been researching all the components necessary (main mechanics, fuel delivery, ignition system ...

I've read up on camera flash ignition, but it sounds like there is a recharge time. I was hoping for somewhat rapid-fire, maybe a few times a second. For the experienced, could a component of the camera flash be added or removed to speed up the charging, perhaps? Thanks for the info so far.

I suppose it could spark multiple times as the button is held. I'm really just needing a single spark, and more could be a nuiscance. It's for a project where timing of the shot is important. I suppose it could be slightly delayed as long as it was consistent. I was looking at some "High Voltage ...

Hello everyone. Been around SpudTech a bit but since it's closed, this is where all the knowledge is at.

I don't know too much about electrical circuits. With a stungun, the button is pressed, capacitor charges and then a spark is formed many times a second as long as the button is held. Is there a ...
