Engineer builds gingerbread house using CAD and lasers, aging droids approve

It’s not that often we see the worlds of baking and technology mix, but when Johan von Konow went about making a traditional gingerbread house for the holidays, he added a laser to the recipe. The engineer and tinkerer first went about designing an accurate, miniature 3D representation of his summer house in a CAD program, with the help of his wife. He then printed outlines of the necessary building blocks onto sheets of baked gingerbread, and used a 50-watt laser engraver to cut them out and score icing guides for the final touches later on. Burnt edges rendered the confectionary inedible, but as its final destination was no longer stomachs, raw lasagna sheets were added for structural support, and hot glue used to bind it all together. If you’ve got all the kit and are feeling inspired by the picture above, the design layout and project walkthrough are available at the source link below. Hansel and Gretel needn’t be worried this time around — the tech used creating this particular gingerbread house has attracted a different kind of aged tenant.

NASA accidentally improves weather forecasting with lunar dust-measuring lasers

NASA accidentally improves weather forecasting with lunar dust-measuring lasers

Anyone that’s ever tried to plan an outdoor activity in advance knows that weather forecasting is not an exact science, but the perpetual sky-watchers at NASA may have inadvertently found a way to improve these guesstimations. They have been testing a laser system for measuring lunar dust and soil kicked up by rocket exhausts, and while using precipitation as a substitute to calibrate the laser, they found they could measure the average size of raindrops passing through it. This value is estimated in current forecasting models, so plugging in some accurate numbers should make those predictions more reliable.

The original mission hasn’t been forgotten, though. Particles whipped up by landing rockets on the moon’s surface could damage what was left behind by the Apollo missions, ruining its scientific and historic value. One of the laser sensors may find its way onto a craft vying for Google’s X Prize, with the results used to determine where vessels can touch down whilst keeping a safe distance from Apollo landing sites. Although an accidental discovery, the system’s other potential career in weather forecasting will also continue to be explored. Now, if only there was a way to make it rain and speed up the testing.

Watch This Laser-Cut Map Appear Before Your Eyes, Block By Block

Not super into cartography? Add some lasers into the mix and see what happens. This video features a laser digging into some metal to create a map of Atlanta, Georgia and it’s mesmerizing to watch it come into being before your eyes. More »

The Military Has Enlisted a Laser-Wielding, Paint-Stripping Robot

Anyone who’s ever done any home renovation knows what a messy job removing paint can be. But imagine that instead of a flat wall you were tasked with stripping a curvy streamlined fighter plane. And the paint you were removing was designed to endure the stresses of supersonic flight. It’s a daunting task, which is why the Air Force wants to hand the job to laser-wielding robots. More »

This 40kW Missile Defense System Will Pew-Pew Missiles Clear Out of the Sky

The wall of hot lead thrown out by a Phalanx system may be effective against inbound artillery threats, but spewing hundreds of rounds to knock out a single bomb isn’t exactly efficient. Instead, one German defense contractor aims to simply fry them out of the sky. More »

How NASA is Making Rockets By Welding Metal Powder with Lasers

Normally, rockets are made of a whole bunch of small parts that are intricately attached to each other to form the body that can actually fly into space. If you could build complex geometrical parts out of a single piece of material, however, things would get much easier. That’s where metal powder and lasers come in. More »

Scientists Can Use Kinect To Pick Up Microscopic Balls with Laser Tweezers

While gamers are off writhing in front of Kinects to control virtual objects on the screens in front of them, scientists are using the same tech for almost the same thing. They’re also flailing in front of sensors, but it’s not Dance Central 3; they’re manipulating real-life microscopic objects with a set of laser tweezers. More »

Laser Cutting Table For Amateurs Slices What You Sketch

In the not-too-distant future home manufacturing will be as commonplace as home printing. Devices like the Makerbot will fuel the revolution, but only when they become as easy to use as this Constructable that precisely cuts materials based on doodles made with a laser pointer. More »

This Clunky iPhone Accessory Measures Distances With Laser Accuracy

The carpenters of the world might want to consider adding an iPhone holster to their toolbelts. Because Prexiso’s new iC4 iPhone accessory promises to make tape measures obsolete, replacing them with an iPhone laser measuring accessory that works alongside an accompanying app. More »

Careful With That Laser Pointer, It Could Put You in Prison

Laser pointers are no joke, and neither is shining them at planes. You may recall that the FBI recently set up a national laser attack task force, and they aren’t kidding around. One laser-happy moron just got sentenced to 18 months in prison. More »
