[Pixel_Outlaw] has been working on a method to capture 360 images with his camera. He’s using a shiny Christmas ball ornament to reflect the entire room into the lens of the camera. In the unwrapped image you can make out the three legs of his tripod. In that snapshot he laid the ornament on the floor and pointed the camera straight down from above.

What catches our attention is the post processing he used to unwrap the image. He loaded up The Gimp, an open source image manipulation program, and used just three steps to unwrap the image. First he cropped the picture so that it was square and the spherical ornament was perfectly centered. Then he ran the polar coordinates filter. Finally he scaled the image, setting the width to be Pi times the height. Works pretty darned well for something that doesn’t take much fiddling.

The ornament wasn’t perfectly smooth (or maybe it was a bit dirty) but you can get a much better starting image if you use a bulb with a silver reflector like we saw in this older hack.

We all love a little bit of multitouch, but we’ve seen so many setups that it is getting a bit less exciting. This one will get your attention with its unique shape. It is a spherical multitouch using all open source software. Well, since the poles are unusable, it might just be toroidal, or cylindrical, but it is still impressive. They are using a convex mirror mounted to the upper most point of the frosted sphere to reflect a projector mounted at the bottom of the base. A web cam pointed at that same mirror picks up reflected IR light from a few emitters. You can catch a video of it after the break.

SPHERES (Synchronized Position Hold, Engage, Reorient Experimental Satellites) are experimental robots made at MIT for the purpose of testing robot locomotion in space. As you can see in the video above, they are capable of maneuvering pretty well. They seem to hold formation fairly tightly. They are using compressed CO2, through 12 different thrusters for positioning. They should be capable of autonomously navigating around each other as well as docking to one another.

This wort cooler looks beautiful. No, it’s not for removing warts, it’s part of the brewing process for the nectar of the gods. Even if it wasn’t meant to create alcohol, we would be drawn in by those pretty copper curves.

We’re not surprised at all to see this remote-controlled bowling ball. We’ve seen remote-controlled spheres several times and this just seems like the logical conclusion. We wish there were some build details though. [via neatorama]

When [Anthony Toth] an aircraft enthusiast, decided remodel his garage, he shot for the sky. He has recreated the first class cabin of a Pan Am 747 circa the 1970s. It took him nearly 20 years to scavenge the parts and over $50,000 to pull it all together. [via makezine]

This super cheap simple cable tester caught our eye. There’s nothing complicated here, pretty common sense really. Why didn’t we think of it?

Over the years, Asimo has become a household name. At least in geek households. We’ve seen him go from crazy looking walking microwave prototype, to giant scary space man monster, to the lovable little guy we know now. You can see the full evolution of Asimo in this picture series.

Got an old box camera? Want to use it with modern 35mm film? Here’s a guide to getting it to work. It mainly just involves making a simple mounting bracket.

We like LEDs a lot, but this is getting ridiculous. This dress has 24,000 LEDs. They power it with iPod batteries spread throughout the dress. This cuts down on the bulk and helps distribute the weight.

Coffee cup technology hasn’t changed much in the last bazillion years. We’re pretty sure cave people carved them from stone, and now they’re made from ceramic which really isn’t that different. Some researchers are changing all that, and designing a coffee cup that is supposed to regulate its temperature in a new way. This mug is manufactured with internal convection channels and is made from a material known for its temperature regulation called PCM. Interesting, but it will probably cost much more than a simple insulated thermos. [via neatorama]

Spherical robots , or in this case RC vehicles are pretty versatile. They travel about the same on most terrains, including water in some cases. That’s not to say that they travel particularly well on those terrains though. The common problem is that they can’t really climb over bumps very well, until now. We’ve seen a few versions of sphere bots, but they all seem to need fairly level smooth surfaces, aside from that one that went in the water. We hadn’t seen any that really had the oomph necessary to climb stairs though. Actually, we still haven’t seen that, but he says it can in the interview you can watch after the break.

[prabbit22m] has written an instructable on how to build a radio controlled sphere. The mechanism is fairly simple, with one drive motor, one servo and a gyro for stability. To turn, the servo shifts the center of gravity off to one side. You can see that the system works pretty well in the video above. If it didn’t have that gyro, it would be insane, believe us, we’ve done our own experimenting. If you like this, but want more features, check out this one that has a camera and takes pictures wherever it goes. We can’t forget Swarm either. The autonomous swarm of robot spheres. Of coarse [prabbit22m] might have the best idea of all. Dress it up as a regular ball to mess with people.

Here’s the plot of one orb exploring a soccer field. Burning Man attendees will most likely see the whole SWARM in full autonomous operation.
