The Science Behind Making the Fastest Possible Pinewood Derby Car

You wouldn’t think that a four-wheeled car would go faster if one of its wheels didn’t touch the ground. Or if its axles were bent. Or if it was designed to grind against a wall. But you’d be wrong, and here’s the science to prove it.

NASA Engineers Built an Insanely Complex Bullet-Time Rig For Fun

Back in May, our friend and ex-NASA JPL engineer Mark Rober, figured out a way to shoot "bullet time" videos on the cheap, with a ceiling fan, a pair of flashlights, and a GoPro. Pretty damn creative, but the rig had its limitations. So Mark set out to find a way to create a similar set-up, this time using a high-end Phantom camera. Thank goodness.

Your Ugly Christmas Sweater Just Went Digital

Mark Rober has been wowing us for three of years now with his innovative, high-tech Halloween costumes. In fact, he got so good at it that he quit his job at NASA to devote himself to "Digital Dudz" full-time.

The NASA Engineer Who Made iPads the Future of Halloween

Two years ago, NASA engineer Mark Rober blew YouTube’s mind with a video of his Halloween costume: a hole in his chest. Or at least it looked like a hole in his chest. In fact, it was an optical illusion made possible by two iPads, a little duct tape and a lot of ingenuity. Well, you won’t believe what he’s been up to since then.

Hacked NES Boots Unwanted Chatterboxes from Your Office

Sick of people coming into your office and talking your ear off? There are plenty of ways to get them to leave, but I’ve never thought of using an old NES system to hurry them on their way.

8 bit nes annoying person remover

Mark Rober and his pal Chad Grant hacked together this NES console – dubbed the “Annoying Person Remover “- which plays classic sound effects from the game when a person enters your space. When they first come in, it plays Mario’s pipe sound, and then the familiar level music and sounds as they hang out. But they only have 400 seconds to complete the level before they’re booted from your office, with that lovely Hurry Up tune that plays when you’re running out of time, and the Game Over tune when it’s time to GTFO.

The build is actually pretty simple, using an old NES, an Arduino board (with Music and Sound add-on), a motion sensor, and a clock display. You can grab all of the information you need to build your own over on Dropbox, including a parts list, and Arduino programming files.

This 8-Bit Annoying Person Remover Has Great Prank Potential

If you start wasting somebody’s time at NASA, this is how they’re going to get you out of their office. Or, it’s how JPL engineer Mark Rober will, anyway. This hacked Nintendo console will definitely put you on notice. More »

Fireplace Ugly Sweater Won’t Light Your Torso on Fire

Just how many ways can one guy use the video capabilities of his mobile devices to entertain us with? Well if you’re tinkerer Mark Rober, I guess the answer is “plenty.” After amusing us with his iPad Halloween costume and Gorilla Cam, Mark is back with another fun hack – the animated ugly sweater.

By mounting an iPad inside of a sweater rigged with a fake fireplace surround, Rober created the illusion of a warm holiday fire burning in the middle of his gut. Here, check it out in action:

You can grab the fireplace animation as part of Mark’s DigitalDudz Christmas iOS app. Be sure to keep an eye out on Mark’s youtube channel in the coming days for a video showing how to make your own ugly fireplace sweater.

The Scooby Doo Picture Frame Gag Gets a High-Tech Spying Twist

Are there any here among us who didn’t watch Scooby Doo as a kid, see a villain spying (with blinking eyes) behind a picture on the wall, and secretly wish we could do that? We may never be allowed to carve holes in our walls, but we can still make that dream come true. More »

This Year’s Best Halloween Costume Is Cheap, Easy, and Awesome [Video]

Last year around this time, a NASA JPL engineer blew us away with a Halloween costume that used two iPads to create the illusion of a gaping hole in his chest. Cool, if you could afford two iPads. For the 99 percent of us that couldn’t, he promised that his 2012 costume would be equally awesome and infinitely more affordable. More »
