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
Matt Meerian hacked an old intercom into a masterpiece by stuffing it with some electronics.This Ferris Bueller’s Day Off Joke Intercom System has the ability to play MP3 audio tracks with the touch of a call button. The entire thing is controlled by a central microcontroller and the attention to detail by using the old NuTone intercom helps pull off the effect. If you are interested in playing with
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
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
Nuxie1 has a new Frequency Counter project kit called FunCount, looks like it would be fun to put together. If you act now you can get it on sale for only $20! Kit Page "This kit includes everything needed to build a frequency counter capable of measuring frequencies from 1Hz to over 2MHz. Perfect for use with the FunGen also available. The kit uses the ATTiny2313 Atmel Microcontroller. The
I could use this unit that Kevin Timmerman designed! I have the same digital caliper that he designed the serial interface for. Project Page. "The caliper sends a burst of data approximately three times each second. Each burst contains 48 bits of data as shown in timing.pdf. The first 24 bits are the position relative to the zero point set on the caliper. The second 24 bits are the
