MR-1.2 Coilgun (UPDATE: NEW INTERIOR PICTURE)
Intro: MR-1.2 Coilgun (UPDATE: NEW INTERIOR PICTURE)
A coilgun that I built. It started as a prototype and I decided to put it in a gun body. I then continued to make improvements from the MR-1 to the current version the MR-1.2. I have not done the math but I intend to do some tests and figure it out soon. Please pardon the rough appearance since this was only a temporary design to house the components.
The MR-1.2 features a two sectioned capacitor bank, new safety insulation, a relay, a safety charging switch, a four layer coil, 3x AA power source (parallel), extra ammo tubes, and a laser sight (actually sighted in).
Gun fires with surprising power. ( If you really want to know ill give you the specs to beat me to the calculations)
I will continue to work and build new guns (much better looking too)
any questions feel free to contact me .
Instructable / video to follow if requested
Charge time: approx 30 sec with 3xAA (longer with less)
Cap bank specs : 14 X 100 uf 330v caps (average of 80-120uf caps)
Coil approx 40mm x 4 layers (inner diameter is bic pen tube)
Relay runs off nine volt with push-button switch
Charging circuit modified to auto-charge
Rounds= 2-3 cm nails/screws (experiments used 6mm airsoft bbs to adjust round placement)
Disclaimer: I accept no responsibility at all for what you may do with this information or any damages/injury/death that may occur.This project uses DEADLY electricity as well as high speed projectiles. Do not under any circumstances try this unless you are trained with high voltage electronics. BE SAFE!
Please note before even considering a similar project: These are very dangerous, not even considering the projectile danger, the electricity is enough to kill you many times over. I use many precautions while working and I have the experience necessary to keep me safe. I do not allow anyone else to use the gun dangerously or open it up. Just in case, I encourage the use of a rubber glove when others are using this just in case (I don't want others to be harmed by my work ever and I alone have the responsibility to decide my own safety and use at my own risk). As for the projectiles, I treat this as a real gun and use full gun range safety procedures. Projectiles will hurt and could be very dangerous. Finally, please don't let this disclaimer get you down, just be safe and have fun!
cheers and please rate and comment!

(9^2 x 13200) / 2000000 = 0.5346J?

I am making a coilgun made of a disposable camera and some capacitors.
I have made a drawing with google sketch-up. Could you please check if I have made all the connections right? ( I am not an expert ……… yet)

Unfortunately I am unable to really see your connections with the link provided. Also, the charging circuit puts more than 400-1200 volts (depending on input voltage.) Your caps have a low voltage rating. Charging such caps comes with extra concern. I would suggest photo flash capacitors from the cameras or an online source. However, several other instructables go into greater detail about these circuits so all problems should be relatively easy to clear up. If you have more questions feel free to ask.,

Seriously dude, this is amazingly awesome.
Now you need to get one of those laser tag rifles and make another, more powerful coil-gun.
