Light LEDs in a Hot Dog

Have you ever seen LEDs powered through a hot dog before? Well Evil Mad Scientist Laboratories has been having some fun running some juice through a hot dog and lighting LEDs that were simply stuck into the hot dog. “If you’re *not* going to eat the hot dog, a neat trick is to stick a bunch of standard LEDs into it. (Yes, this really works!) Apparently the voltage between nearby

Exploding a Potato with Defibrillator Capacitor

  This video of a Potato Exploding with the discharge of a Defibrillator Capacitor is very impressive. The 54uF/4200V capacitor was charged up to 3000VDC prior to the discharge. If I ever have a heart attack I think I might just tough it out and hope for the best. 🙂

Holographic Video

Could the technology that MIT’s Michael Bove is working on change computer displays as we know them today? It wasn’t long ago that LCD flat screens took the market over. Are we going to see a similar change when Holographic Video technology matures? “The Media Lab’s video holograms appear to float above a piece of frosted glass. An electronic device behind the glass, called a light modu­lator, reproduces interference patterns

DIY Laser Engraver / Cutter

If you ever wanted to do some laser engraving, this project might be of some interest to you. The circuit is basically a variable voltage regulator that is powering a high power laser. I would highly recommend laser goggles when experimenting with devices like this. “This laser will immediately BURN AND CUT anything you put in front of it faster than a hot knife through soft butter. And, a laser

LEGO NXT Rubik's cube solver

Daniele Benedettelli made a LEGO robot that can solve the Rubik’s Cube automatically. Looks like the robot has been well thought of and constructed. Video after the jump. “A motor actuates a prismatic joint that pushes the side of the cube; another rotates the cube’s support; the third one has the double function to help the pusher arm to accomodate the cube on the support and to hold the cube

iPhone Taken Apart

Hacked Gadgets doesn’t normally cover off the shelf items but there has been so much buzz over the iPhone and the guts do look interesting. One of our advertisers, iFixit, bought a perfectly good iPhone and took it apart to see what makes it tick. By the looks of it Apple doesn’t think the battery will ever need replacing… Great job guys! “Samsung manufactured Apple ARM chip. Numbers: 339S0030ARM, 8900B

Jet Powered Sinclair C5

The Sinclair C5 doesn’t look like a vehicle that would turn many heads. Dropping a Jet Engine into the Sinclair sure changes that! Video after the jump. “I purchased the C5 from a nice chap called Ron, the entire chassis is going to be replaced and the power source will be a gas turbine. I’m going to drop the Turboshaft Kart and use the engine as a Turbo Jet conversion
