The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
I've started working on this project about a week ago, and wanted to start posting about it. So here goes...
It's going to be a fully portable, 3 stage coilgun. I'm hoping to achieve a speed of 60+ meters per second with this gun. When i'm done with it I want it to be able to shoot through almost anything practical. The gun itself is going to be a rifle like design, being as small and compact as possible.
Yeah i know...for some reason youtube wont let me upload the video...it keeps failing...and i forgot to take that bit out of there x.x ill do that right now! and ill update it when i get the video uploaded....
I now have some videos uploaded up top there ^ and i've ordered pretty much everything except the capacitors and the triacs. I'll add more videos as i go...

Looking good! I just have a couple questions: First, the optical sensors on the first stage are there to trigger the second stage, correct? If so I assume all your coils will be pushed up against each other as close as possible. Second, I may have missed it but it seems like that brass barrel isn't slotted. You probably want to do that before you spend a lot of time on your coils as that will provide a noticeable increase in power. Or at least it did in mine. Also, are you going to actively monitor your cap charge and cut the power when charge is reached? Or are you just going to vary the input voltage to the point that it can't charge past the max ratings. Speaking of max ratings, you mentioned something about 550v caps in your videos I think? Is that correct?
All in all nice job. I love the point to point construction of your break beam sensors. Keep up the good work!
First, yes, they're there to trigger the second stage, and the goal is to move them around till they are perfectly aligned.
Second, i'm just working on test coils right now. Once I build the final coils they will be slotted and much neater than they currently are.
Third, I plan on using the regulator circuitry provided with uzzors2k's flyback capacitor charger, because i'll be using an 18.5v battery, which will give almost a 700v output (description says 14.8v but i've changed my mind)
Fourth, i'll be using 450v caps for the final design, if I said anything about 550v caps then I must of really been out of it O.o
