I have a few lawn mower ignition coils lying around, so I thought I would make something out of them. The problem is I do not know how to make the coil run off a battery. Here is a picture of the coil. I would greatly appreciate any help.

If I energize a coil and then switch it off, I get a collapsing field, I would like to capture this field and use it to energize a seperate coil, is that possible, and how would I do it. Thanks.

I am looking to build my first coil gun. I don't have much experience with capacitors/capacitor banks. I'm looking for a recommendation on capacitors that I could use for a coil gun that would make a proof of concept coil gun that would be safe for my first time venturing into this area. Any Ideas? I would probably order the capacitors from Digi-Key rather then harvesting them from other electronics. Thanks!

I found a few hv diode (1 Mega Volt) and some around 240 kv, but the question that I asked myself was if I could get DC current from a Tesla coil by rectifying it with a proper HV diode. Is it possible???

How can we switch power between coils on a multistage coil gun setup (3, for example)? What i am reading out there is people using physical switches to infrared sensor but i couldn't understand much especially on how can we implement it. I'll be grateful for any explanation anyone can tell me to. Thanks! Sorry for my bad english :)

I need to know what the best dimensions for the primary coil would be for this secondary: 505 mm length 0.72 mm wire thickness (21 gauge magnet wire) and 60.325 mm diameter I would appreciate some sort of formula where i can just substitute the primary voltage and get a measurement but if that is not possible use 27 volts for the primary voltage. If you have suggestions as to other aspects of the coil i could improve, i would be happy to listen. It is a solid state coil and i will probably put a capacitor in series with the primary to make it doubly resonant.

The summer bored-ness has finally kicked in, and I would like to build a coil gun. The usual idea is just to charge some capacitors, and then discharge then into a coil, but it is possible to use the 3.3v rail (or any rail) of a standard computer power supply to power a coil gun? The goal to have rapid fire ability (which is hard to accomplish with capacitors due to charge time), and not use a transformer (because I am to cheap to go and buy a decent one from Radioshack, or any other store)

I have been trying to construct a simple flash curcuit coil gun as i have seen on the internet. I thought i had everything hooked up right but when i go to fire i get a nice spark but no acceleration what so ever. Can anyone tell me the proper materials to use and a step-by-step in coil construction and how to hook up the leads properly TO MAKE IT WORK! any incite is greatly appreciated

Alright, I ask that everyone please read everything in this question before answering :). I hopefully going to be very thorough. I am building a tesla coil and am just about to give up and buy a NST. I have many high voltage sources laying around, but, so far I haven't had much luck. The first plan was to use a large ballast (florescent light) to drive a flyback, but it was to powerful, so I got a CFL driver, and it didn't work (not the driver so much as the whole project) so now I am left with an ignition coil. I know that I can use a light dimmer switch to power it, but it will still be 60hz I think and I here that is not safe for a tesla coil. Although, I don't think anyone is going to let high frequency and voltage arc across their skin anyway. So will something at this low of a frequency still work to power a tesla coil. If not do you have any ideas I can use. I have a flyback transformer and an ignition coil so any ideas that come to mind please share.

Im looking for advice on how to make a "rail/coil gun", i understand the principals behind it and the componets needed but id like to know what is the most efficent and powerfull componets. have in mind im looking at making the gun completly portable but a stationary charging for the battery would be prefered id like to keep the device 12v dc if possible using a battery to charge up capacitors, a switching device which allows the capacitors to charge and switch of the battery input automatically to prevent the electricity draining back into the battery. also another switch which discharges the capacitors into the coils but is switched manually(trigger), multistaged coils hopefully around 16 if possible( the way i see it lots of power running into lots of coils means the projectile traveling faster and further) ive also been told that once the coils have been charged they'll need to be discharged within micro seconds and theres a certain componet which allows that im not sure exactly what that is?. Having many coils means ill need a timing mechanism to activate the coil when the projectile is within the magnetic field, ive done a bit of research on that and come up with a microswitch between every coil or infared diode and a photosensitive diode(not sure exactly the name of the second one). 1. how many rows of coils would i need for each coil, what gauge wire would best suit my needs, what grade of wire, a way to prevent the magnetic field affecting the coils next to it, to optimize the energy in the capacitors should i start with a larger gauge wire at the first coil and slowly decrease it per coil, 2. what size capacitors would best suit my needs also bieng small in size, also would it be better have 1 or 2 capacitors per coil 3. what sort of switching device would be best for charging the capacitors and isolating the battery when there charged 4. is there another switching device for turning on each coil seperatly when the projectile is in range of the coils magnetic field to optimize the use of the magnetic field 5. more info on when the coil needs to discharge would also be great any ideas or inputs would be greatly appreciated no matter how big or small or if only concerns a certain aspect, cheers, chris cross australia

HiI am planning to build a small (length about 15 cm) portable coil gun. There are some really good intructables out there. (I still don't have enough knowledge of how to build this thing) I found this site to be pretty interesting. http://www.jeffhove.com/robots/coilgunhowto.html How can I make a powerful coil gun like that with capacitors (not that whole blob of camera stuff)? I am hoping that it could be rechargeable, perhaps by a USB connector (5V). But that would not last long right? So I guess by adding some batteries would help. Trying to get this coil gun to the smallest size with a powerful blow. By the way, there is something called EMF that affects the system?Thanks

I’ve made a coil gun out of a disposable camera (utilizing it’s capacitor). It shot bbs about 3 inches, and then they’d roll along the floor. To get coil guns to work you need a high voltage, discharged quickly. I’ve seen there are cheap stunguns on Ebay you can buy for $12-$15 shipped. In the 2.8 million volts range. I think they have enough voltage to propel a bb pretty good, but my question is do they discharge fast enough?

Instructables member Phenoptix put me onto a fun event this weekend - two chaps from the Extreme Electronics (Derek and Dave) website led an informal workshop on how to build a classic Tesla coil, from power supply through to topload and breakout. They also brought along a few of their toys to demonstrate what they were talking about, and I grabbed a few (shaky) videos. Thanks to Derek & Dave, it was a grand night, and thanks to the "Lone Scout" for the supply of coffee.
