Coilgun is like a slingshot from the future. Whilst it’s kind of useless it’s a lot of fun to play with. I’m going to show you how to build one without using huge and expensive capacitors. My design powers coils directly from batteries and yes I mean coils since you can add as many as you want to make it more or less powerful. Be sure to check out the video I made. There are many details but more importantly TESTING at the end. I mean shooting stuff. It’s the same thing when you’re building a coilgun :D I’ll be going into details of the electronics here but I’ll not be making any fancy case. That will be my future video so subscribe if you want to see that. For now my coilgun is taped to a scrap piece of wood but hey, it works.”
