Take a tour of the Mutex laboratories, where mutants are made and nothing could possibly ever go wrong. [Steve] directed us to these videos of the Halloween set up he did with his son this year. Neighbor kids got to go on an action packed tour where mutants break free from their cages and have to be neutralized with special ray guns. Wow, why didn’t this guy live near us when we were kids? Check out a behind the scenes walk through with some good technical stuff after the break.

Liquid Tree

November 11, 2008 by Kimberly Lau 22 Comments

Liquid Tree is decorative, functional, and green. It’s a liquid feedback display created by [Jia Yi Lin] that is designed to tell you exactly how much water you’re wasting in the shower. Behind the pretty tubes is some interesting hardware. [Lin] used an Arduino board, and based her code off the Unipolar Stepper example. She’s posted her own code and wiring for the project. When hot water is turned on, the motors decrease the amount of liquid in the tubes. This causes the pattern to slowly disappear, indicating water consumed.

Super Nintendo Clock

[Aaron] sent us this sweet Super Nintendo Clock that he built. When he found himself with a broken SNES, a friend challenged him to out do his previous NES clock. This time, the display would be located in the cartridge, and removable. Setting the time is done on the SNES controller and seems to work pretty well as you can see in the video after the break.

Kill A Watt Teardown

Come on, folks. If we keep tearing apart everything that’s handed to us, we’ll never get nice things. SparkFun got their mitts on two Kill A Watts and proceeded to plug them into everything and then dismantled them to see how they work. The Kill A Watt keeps track of how much power is used over time. The largest load they found was their soda machine using 500W (should probably add a motion sensor to that). They plugged a meter on either side of a UPS and found out that it uses 5W just to charge. On the inside of the meter, there isn’t anything too substantial. One unlabeled IC runs the whole show.

WaldFlöte: Midi Controlled Pipe Organ

November 10, 2008 by Caleb Kraft 7 Comments

Members of Dorkbot Edinburgh have done what most of us would do if we had a 19th century pipe organ. They hacked it to be midi controlled. The organ is located above a cafe owned by the university of Edinburgh. Students have been repairing and modifying it to get it back in working order.

The electronics are composed of an Xilinx Spartan-3E Starter Kit as the brains and a Microblaze processor converting midi events for the solenoids. The cool thing is that none of this required any permanent modification to the organ itself. It can all be removed to put the organ back in normal playing condition. Check out the video after the break for some classical Van Halen.

CatGenie Hacking

November 7, 2008 by Caleb Kraft 37 Comments

[ScottSEA] has six cats. As you can imagine, with six cats, a simple litter box just doesn’t cut it. [ScottSEA] uses the CatGenie. While a self cleaning cat toilet is a technical marvel, it has one major drawback. Much like an ink jet printer, it has disposable cartridges. Those cartridges, just ike some print cartridges, have a built in counter that disables them after so many uses. After adding up the totals for six cats worth of cartridge use, [ScottSEA] started hacking. He has posted directions on how to manually refill them, as well as reset the internal counter using an Arduino.

We suggest that he find a way to harness all that cat power for his home electronics. How many watts could you produce per cat?

Multi-Color Fog Spreader

Though we’re pretty sure this was meant for Halloween, we think it would be a perfect addition to your election night party. [marc92] shows us how he built a fog spreader with red or blue lighting. Fog machines generally spit out the fog from a single point, relying on the breeze to spread it around. [marc92] wanted it spread a little more evenly, as well as some nice mood lighting. He built a pipe system that would emit fog from a much larger area. Mounted on the pipe are red and blue LEDs. Mix this with some of the election lighting systems and you’re set for a party. We know this is an extremely simple project, so it should give you plenty of time to get out and vote before the polls close.
