For those unfortunate few of you who don’t already have a plasma cutter sitting around, [jandgse812] is here to help. He walks you through the process of building your own plasma cutter from scratch. Adding up the list of parts brings the total project to roughly $300. He has included visual diagrams for all the wiring as well as specific part numbers and where to get them. Be careful, this is potentially very dangerous, but also very cool. You may need to get a copy of the mission impossible theme to play whenever you use it. At least, that’s what [jandgse812] recommends. You can see a video of it in action after the break.
