Flying Foam Printer – Flogos

 

This printer uses helium to blow foam bubbles through custom advertising stencils. The resulting foam advertising flies rigt out of the printer and into the sky.

I love this concept, but when it comes to shapes, all I can think of is unleashing thousands and thousands of space invaders.

Robotic Bull for the Military

War is about to change in a way not seen since the invention of the missile. DARPA (the defense Department’s advanced research wing) is showing off a scaled up version of Big Dog they are calling Alpha Dog, or Bull Dog. It resembles an actual bull more than any kind of dog, which reminds me of a recent story on adaptive camouflage in which researchers were attaching panels to mask most the infrared signature of tanks, and could project what would look like a walking cow onto the siede of the tank to further remove suspicion. In the case of Alpha dog, rather than projecting the cow on the tank, they seem to be putting the tank in the cow.

More interesting though, is what this says about the ever present arms race. The United States has been the dominant military power in the world, but has had troubles of late with small decentralized terrorist groups. Imagine if they were to convert an auto manufacturer to pump out tens of thousands of weaponized robotic mountain goats. It sounds a bit far fetched, but I don’t see what is stopping them really. Just with the tech they have shown the public, they already show themselves to have the tech not only to do this, but also to make them mostly autonomous. The toughest part at this point might just be giving them a power source that wouldn’t give us problems if it were captured.

It makes sense that the U.S. has cut funding for some of its largest budgeted fighter jets and other new tech. The next war will be lost to the people with the best drone offense and laser defense. What chance does a fighter pilot have against a drone immune to G forces, or a ground based laser system that shreds it from miles away at the speed of light?

In related news, there have been reports that the U.S. drones have contracted some kind of computer virus.

Popsicle Stick Bomb

Why hasn’t anyone told me about popsicle stick bombs? These have so much more potential for mischief than dominoes.

For some simple instructions and complex constructions out of these frame bombs, check out framebomb.com

And if the thought of eating all those popsicles makes you blue, you can get a thousand popsicle sticks on amazon for under ten bucks.

SmartBird – Festo Robotic Flapping Bird

Not a year goes by lately without Festo coming out with some awesome new biomimetic toys, well, industrial automation really, but you can bet these will be in toy stores in some form within a year or two.

This time, they’ve created a bionic seagull, fully autonomous from takeoff to landing. It uses the same kind of active torsion to take advantage of vortices that flying animals use to get that extra edge in flight that has previously been hard to duplicate in man made devices. Turning is accomplished wit a tilt of the tail.

Rather than using lighter than air materials like in their past projects,the SmartBird frame is constructed from carbon fiber, polyeurathane foam and other lightweight but strong materials, yet they’ve still managed to keep it aloft even with the weight of the brains, batteries, motors, and even a radio transmitter. Video below.

Getting Through Math Class With ADHD

If you are anything like me, math class was only good for one thing: Quieting down that analytical part of the brain long enough to get in some good doodling, which is why, in order to pass a math class, I had to stop bringing paper and just hope I could absorb something from the lecture before passing out from boredom. Now I find I just had the wrong teacher. If Vi Hart were my teacher, I think I would have learned at lightning speed. Check out the videos above for a sample.

If you like the concept of learning math, but don’t relish the slogging through textbooks, I highly recommend her site. I actually learned some very helpful things in most of the videos I’ve watched so far, and I enjoyed it. http://vihart.com/

3D Alternative to Glasses

Johnathan Post has a very impressive new method for seeing 3D content on video screens without shutter glasses. While there are some obvious reasons why this particular method isn’t going to catch on, I really am vastly impressed with his ingenuity.

Thermochromic Pigment

I’ve been wondering ever since the Hypercolor days why no one sells a house paint that changes from black to white as it gets warm. The same goes for shingles, jackets, etc. I can only assume that the costs of production must still outweigh their value as an active thermal insulation, but now that I see this, I’m tempted to at least make myself a jacket. In the video below, there is a tutorial on how to make fabric that quickly changes from black to white as it gets hot.

Hologram Maker

ZebraImaging is by far the best hologram maker I’ve seen. Their ZScape™ holograms are huge, hi resolution, color, have a strong 3D effect, and are almost perfectly smooth in motion. These things compare to the bird on your credit card like an Etch-a-Sketch does to an I-Max. Check out the video below, it’s pretty stunning.

Zebra Imaging sells their pulse laser hologram printers, as well as selling and making hologram prints. Their pricing isn’t bad either, considering the quality and size. Most people could afford a print if they made it a priority in their life. Hopefully the price will come down further soon.

Rooster SteadyCam

If you want to avoid shakycam footage, there are a ton of ways to stabilize your camera, ranging from DIY projects, to a huge variety of devices (see here) ranging from simple and affordable, all the way to professional units where if you have to ask the price, you can’t afford them. All these options weren’t enough for this guy though, he’s taken the DIY approach to a new level, giving his rooster a helmet cam. If you’ve ever picked up a chicken, you know that when you move their body, their head stays in the same place (vestibular ocular reflex).

Why buy a fancy steadycam, when you can just carry a chicken? Video below.

It seems to me he has the camera pointed the wrong way. Chickens don’t look straight ahead, they look to the side. The real challenge here is to keep the chicken interested in looking at what you are filming, which could be a good way to make movies for people with short attention spans.

Skittering Table

This is a fun table design concept. I’m not sure what situations it would be better than legs, and it’s a bit cobbled together, with all the support braces and legs all over the place, but it’s quite a conversation piece. I’d love to see a more polished version. (via Thereifixedit)
