The guys from NerdKits have come up with a neat way to drive a small RC car using their iPhone. The video below goes through some of the details, if you have some similar ideas you can use their code as a starting point since they have made it available! "Layering different simple systems together to perform one complex task is really at the heart of what engineering is
If you are looking to make a cool Water Bottle Launcher that can launch 2 liter pop bottles with some good force have a look at this one at Science Toy Maker. Have a look here for full build instructions. "2-liter soda bottles turned water rockets are as shrieking good a time as a water park and a lot easier to build! They streak into the air faster than
This DIY Wind Turbine looks like it would have been lots of fun to build. This is just one of the cool creations that Mike Davis has put together. Have a look at his main page only if you have an hour or so of free time to look around. 🙂 "I started by Googling for information on home-built wind turbines. There are a lot of them out
Funky Alex has come up with a cool Dual Speaker Laser X/Y Mirror Display. I think with just a bit more volume or some speakers with a longer throw the display would be big and bold. "I have accomplished with laser show program for mac(is also possible with a frequency generator program)and music cool effects. The vibrations from the 2 base speakers (with 1 mirror an each speaker) makes
With inspiration from this Sprites Mods hack, Bidouille.org has done a cool new version of the hack. Using an Arduino Microcontroller and some custom code the data from the Agilent technologies chip is retrieved. Have a look at this document (PDF) for some more details on what makes the technology work. "Relationship to Object Motion The relationship between the optical flow in the image plane and the velocities of
Gary Eneberg has made a great looking pair of speakers and documented the steps. For a total cost of $430 US it is a fantastic deal for such a nice piece of work. "The enclosures were made using 3/4" Baltic Birch plywood except for the front baffle which consists of two pieces of 1/2" plywood laminated together. The inner piece of the front baffle fits tightly into the cabinet
Tim Robinson wanted to know how much energy his household was spending on gas and electricity. How convenient was it that the gas meter that was installed has a rotating magnet! A switch that is commonly used for door alarm switches looks like the perfect match. Have a look at the project site for some details of his gas and electrical monitoring solution. "The goal was to find a
