Some researchers from Oxford University have come up with a way to produce high-speed video from a one mega-pixel camera. They’re calling the method Temporal Pixel Multiplexing. This method adds a digital micromirror device in line with the camera lens. These chips house over a million mirrors and can be found in home theater projectors. By placing one in front of the digital camera, a longer exposure can be used while the DMD redirects the light. This way, one high-resolution image actually contains multiple frames of lower-resolution video. The video is still decent quality and, at a far lower cost than common high-speed video equipment, this is a worthwhile trade off.

Do you ever wonder what projects your neighbors have going on in their basements? [Will Jack’s] neighbors might be surprised to find he’s building a fusion reactor. The first step toward completing a Farsworth-Hirsch Fusor is up and running. The picture above shows heated plasma contained in a magnetic field. Next he just needs to up the voltage and inject some deuterium.
Yeah right! Deuterium, aka heavy water, is extremely rare and very difficult to refine. If you’re not familiar with the substance, you should get your hands on the NOVA episode: Hitler’s Sunken Secrets.
We’re glad to see that [Will Jack] is donning a lead vest for protections. [Will O’Brien] cautioned us about the stray X-rays these things produce when he covered fusors back in 2007.
[Brad] has continued working on the Super Pixel Bros game. We saw a glimpse of this a few months ago but he’s added a lot since then. The game now has enemies; one type is similar to Bullet Bill, another type drops from the sky and walks toward you, kind of like a Goomba. Game play is quite responsive and it’s amazing what he has accomplished with such low resolution. In the video after the break [Brad] mentions that a friend is working on sound effects for jumps and block breaking. We’re assuming that the audio track in the background is already coming from the LEDBOY speaker.
Which reminds us, if you haven’t checked out the hardware, do so now. That enameled wire mess makes us shudder just a bit. There many be a kit version coming that will save you the point-to-point soldering madness. If that’s part of the fun for you keep an eye out for the forthcoming release of the hardware schematics.

These boxes, called Flexi Knobs, work like a wireless Atari paddle and mouse rolled into one. Each has a rotary encoder that can also be clicked like a button. On the inside is a wireless optical mouse which controls an on-screen cursor which matches the color of the knob. In the video after the break you can see these are being used as midi controls. Each cursor can be locked onto a virtual knob, giving it a physical interface. Because there are several units being used on one machine this creates something of an abstract multi-touch system. This would make a nice interface for other applications with a plethora of settings, like Blender.

[thetanktheory] sent us his glove mouse modification. He has gutted his mouse and mounted the parts on a glove. This is interesting, as he doesn’t have to place his hand on the mouse any more, he just plops it down on any surface and starts mousing. He claims that it is helping his twitch reactions in gaming as somehow it requires less force, but we still see the circuit and batteries mounted on the back of his hand, so we’re not sure how it is helping. Maybe if he moved the laser to his finger tips, he’d be more accurate.
