Fire Wire - Burning Steel Wool

  Fire Wire is a way to put on a simple but cool fire display. All you need to do is tie some steel wool to the end of some wire using a slip knot. Then using a lighter light the steel wool. Spinning the burning steel wool produces an impressive (and possibly dangerous) shower of burning metal particles.  

Steam Punk Tesla CD Turbine Skill Saw

  Here is a creative way to carve your pumpkin next year! Have a look at this Instructable for more details. “Pumpkin carving with the Tesla CD Turbine, Steampunk Edition. New design of the little turbine made from CD’s gets put to the test. Will the barely held on, magnetically-coupled, spinning Skilsaw blade, cut through the tough and messy flesh of the poor, tearful Pumpkin??” Thanks Rick

Tesla CD Turbine

  I don’t think this engine is very efficient or reliable but sure looks like lots of fun to build. 🙂 However I wouldn’t recommend spinning a saw blade at high RPM when it is magnetically connected to a plastic CD cake box. “The Making of the Tesla CD Turbine Prototype is the story of how the Tesla CD Turbine came into being. It starts with the initial thought process

High Power Demonstrations

  Mental note, don’t short out bus bars. 🙂 “Here arcs were intentionally initiated by bridging wires across three copper bus bars in a testing laboratory. Three phase 480 volt power was then applied across the bus bars for about 1 second. The wires immediately explode, forming a conductive plasma which forms high current power arcs between phases. The actual fault current in the demonstration is not known, but is

Huge Rubiks Cube Subwoofer

  If you are wanting to add some bass to your home theater why build a Huge Rubik’s Cube Subwoofer! It isn’t as big as this gigantic subwoofer but it looks a lot more fun.   "Sealed Enclosure: 3 Cu.

Halloween Light Show - Parallel Port Relay Controller Based

  Check out this cool Parallel Port Relay Controller Based Halloween Light Show it shows what some creative thinking and a bit of code and hardware can produce. “The most important thing you are gonna need is the controller. There are many out there, but for this tutorial (its easiest and cheapest) we are gonna use the kit74 parallel relay board. 30$, 35$ assembled. This circuit is going to interface

Computer Controlled Water Spray System

  Got kids cutting through your yard all the time? Is the solution a fence? No way that is what everyone else does and is so yesterday… What a true geek does is builds a Computer Controlled Water Spray System to get the job done! “As you can see I have met a bunch of my goals in prototype 1, I can shoot about 30 feet and can cover a
