While building some nixie clocks,[Blue_Metal] ended up destroying a few tubes. He found that having a tester sitting around would have been most helpful. Taking some pride in his tools, he put some major effort into building his nixie tube tester. It is quite visually pleasing, featuring hand cut brass framing, custom etched information panels. Scroll through his flickr set to see the build process in detail.

Stickybot has gone through a pretty radical upgrade. You may recall the gecko looking glass walking bot from all over the net. While it was pretty cool, the technology has gone much further. Not only is it designed to look like a gecko, the feet are actually made to adhere to surfaces in the same manner. They are using an adhesive system based off Van Der Waals forces. Though the stickybot 3 doesn’t walk yet, the feet are already impressive. Look how little of the foot is actually making contact with the glass. See how easily he can remove and re-adhere it? Simply amazing.

If you are anything like us, you are suddenly filled with childlike glee when you think of big fluffy poofs of cotton candy. The thought of making it at home has a certain appeal, but that machine is a mystery reserved only for those elite enough to get through cotton candy maker school. Or so we thought. As it turns out, it is actually quite simple. You can make one and be serving cotton candy in an afternoon with parts you probably have sitting around. The video above is pretty easy to follow, but if you want more information, there’s an instructable as well.

[Alan] noticed that his external hard drive was getting quite hot to the touch after a few hours. He says that it was probably designed to handle the heat sufficiently, he thought it would be fun to beef it up. He’s using a pic 12f675 microcontroller as the brain and an LM35 temperature sensor. The Fan speed is varried in 8 steps from 35 degrees C to 45 degrees C.

This cool mod brings force feedback to the Nintendo DS. There’s a motor with an offset weight mounted inside the DS for vibration and some nice SMD LEDs plopped in there for good measure. The force feedback is being controlled via a picaxe mocrocontroller and triggered from the analog audio signal. While using the analog audio may not be the most precise method, he says that the results are pretty decent.

Finally, a good use for those EEG headsets. [Andrew] has set up a system that will turn his TV on and off if he focuses hard enough. He’s got the software set to trigger an IR LED when the “strength” gets high enough. When the action starts, around 4:30 in the video, you can see that when he raises his arm the meter on the screen begins to raise and the TV turns on. Though not immediately useful, we can’t help but get a little excited seeing him literally turn his TV on with a thought.
[Adam] sent in this cool project. He has modified a Polaroid J66 camera to use modern film. Most of the initial modifications look fairly simple, but things get a little more complicated when they also convert it to a fully manual camera. There is a section that explains a neat little trick of using a cheap solar panel attached to your computer sound card to figure out what ISO the camera is shooting at.
