Fresh hacks every day
[Electorials] actually makes working with a flyback inverter sound rather easy. This comes hot on the heals of the huge high voltage collection we saw the other day, but slows way down in the presentation of information. This makes the project very approachable for the newbie, especially considering that the majority of the testing is done with low voltages. He's using a flyback transform for … [Read more...]
This 5-axis CNC router could soon be an open source tool. [Mike Calvino] built it for the School of Architecture at the University of Arkansas. It can be used as a router or as a plasma cutter/welder. Now he's trying to raise some money that will underwrite his time and effort to develop and release instructions, design files, and specifications to make it an open source hardware project. It … [Read more...]
While there are many ways to produce audible sound, Plasma Speakers have to be one of the coolest. Usually very complex and expensive, we received a tip for a beginners guide to making one of these impressive novelties. Handily included are a set of schematics (one very simple schematic, the other with a few artistic illustrations). There are also a set of warnings, which include sound advice to … [Read more...]
[Todd Harrison] put together a welding cart that has all kinds of tricks built-in. The carcass is a cheap rolling cart that has been reinforced with steel plate and beefier wheels. The top tray can be loaded up with fire brick for oxygen-acetylene welding or with a grate for cutting. That grate lets the slag fall through and into the red-rimmed fire-box below. Finally, there's a steel plate to … [Read more...]
Winscape will let you replace that garbage-strewn ally view with just about anything you want. The two windows above are actually plasma screen televisions. In between them you can spot a Nintendo Wii Remote that is used to track an IR badge worn by the person in the room. As they move, the images on the screens are changes to simulate the change in perspective you would see out of a real-world … [Read more...]
This one came out over a year ago and we missed it. [Daqq] has made a plasma ball out of a nixie tube. All that was required was the transformer from a cold cathode meant for computers and a nixie tube. He did have to do a tiny bit of modification to the power supply, which you can see on the project page. This isn't the most useful project, since you can't really see much of the plasma, but it … [Read more...]
Some of you probably have plans to build your own spaceships, we know we do. Well, the propulsion system can be a bit tricky, especially if you plan on using plasma drives. This breakdown and build of a simple plasma thruster should help you on your way. All you really need is some Argon, a large capacitor bank, and a custom nozzle. You've already got most of that right? As usual, be very careful. … [Read more...]
