Who knew you could build your own digital computer out of paperclips? EMSL did a great feature on the guide which was published in 1968.
Trying to keep your Raspberry Pi from overheating? Make it log its core temperature on the web.
[Lennart] must be some kind of Eagle CAD guru. Check out these PCBs that incorporate his logo in a very artsy way.
No need for a tripod when you can just strap the video camera to your safety glasses for some POV project videos.
Turn your Pogoplug E-02 into a Shairport (Airplay clone) music hub. Just follow this guide which installs Arch Linux and all the supporting packages you need.
We don’t have the background to judge the quality of this build. But you have to admit it’s pretty neat to see a radio telescope built using a tin can and an umbrella.
Dead rodent email: get a notification every time your mouse trap springs.
Induction cook top provides power too
We’re familiar with induction cook tops but we never thought to power a microcontroller with one. [Thanks Hadez]
We’ve been big fans of the chain reaction demonstration using ping-pong balls and mouse traps ever since we saw [Mr. Wizard] do it back in the day. If you don’t know what we’re talking about, check out this demonstration that is analogous of a fission reaction. [Thanks nateL]
Phone tripod enclosure
If you’re interested in using your smart phone for some photography, [Mike] has a nice wood and elastic mount for an iPhone which you might try yourself.
Bicycle snow tires
Admittedly we’re a bit late on this one. But keep it in mind for next year: you can use some zip ties for added traction on your bike when it snows. [Thanks Rob]
Now you can BE mario
A little Kinect script lets this gentleman play Super Mario Bros. with his body. Now you can have all the fun that goes along with being a pixellated character stuck in a two-dimensional environment (plus, there are shrooms). [Thanks Das_Coach via Slashdot]
[Ned] had a mouse problem in a very uncomfortable place.
No, not like the back of a Volkswagen, in his ceiling. He wanted to put a mouse trap up there to take care of the critter, but knowing how nasty a tripped trap can be after a few days, he was hesitant. He recalled a project he saw online where a mouse trap was wired like a dead man’s switch and he got to work putting together a trap of his own.
He scavenged some parts from around the house and wired up the mouse trap so that a pair of LEDs were lit so long as the trap had not been sprung on an unsuspecting mouse. Once a mouse is caught in the trap, his circuit is broken, and the LEDs go off, letting [Ned] know it’s time to poke his head back up into the ceiling and clean things up.
While his trap is decidedly low-tech, we always enjoy seeing a cheap and easy solution to annoying, everyday problems.
[scott] had a need to capture a mouse and wanted to learn about how to program an arduino, so he built an Arduino controlled mousetrap. It is made from things he had laying around the house, like some Tupperware containers and wooden rods. The program is pretty simple, when a trip wire is touched, the servo jerks the wooden rod out of the way, closing the container. You can see it working after the break. The trip wire seems like a big failure point. he states that it is just a wire, slightly above a tin foil strip. That seems like it would only be a tiny area that the mouse would need to touch to trigger it. What better switch could he design as cheap and quick as possible?
