There are some projects that just take your breath away, this 555 Decimal Adding Machine by Alan Yates is definitely one of those. Via: EMSL “The quiescent device pulls 450 mA from its 9 volt supply. Yep, 4 watts! You can feel the warmth coming from the back of it. I could not find ICM7555s in quantity, so was forced to use LM555CNs, making it a rather power hungry device.
Check out this keyboard mod that Charlie Webb from NortHACKton came up with. You can never have too much automation, I love the big red button which allows a predetermined string of text to be sent to the computer when pressed. There are some additional pictures and schematics here. “NortHACKton member, Charlie Webb, recently completed this project based around an arduino and a keyboard. Fed up with the way Windows
Kevin Pineda, Theo Jeneotopulos, Victor Cabrera, Michel Sanchez and Sergio Martinez from the Florida International University developed this IR Mouse Pen Idea they call KeyMoTe. It uses a camera which is looking at the user who holds an IR pen. The camera is connected to an arduino which sends mouse information to the computer. An off the shelf blue tooth keyboards allows the user to also type from a distance.
Our friend Bob Davis has been working on a new version of his DIY Earthquake Detection which monitors magnetic fields to attempt to predict earthquakes. This new design is using UGN3503 hall effect devices and an Arduino. “I came up with this idea over 10 years ago because animals behave strangely before earthquakes. They know something is about to happen. I also know animals can navigate magnetically. If you put
Have a look at the Gunchuck, it comprises of a Nunchuck, an Arduino and a BB-Gun. This would be lots of fun if the gun was changed out with a super soaker and mounted on the peak of your roof. You could use a Web cam to watch the dot at night and terrorize the kids that might be out past their bedtime. I think Quicksilverhacks should use his voice
Wow camera technology is getting small! When attaching the wires to the camera is one of the main challenges you know you are dealing with something that is very small. These cameras are build using VSLI production just like chips are made. Awaiba has been working on perfecting this camera for a long time, it is best suited for the medical field but I can think of lots of other
Fellow Canadian Laurence White from Electro-MCU-Stuff has built a neat looking project which uses a piezoelectric element from a tweeter to detect vibrations. He is using a Zilog eZ8 series microcontroller which breaks the Atmel, Microchip or TI norm for the projects we have seen around. I remember Zilog seemed to be very popular years ago but in recent years I haven’t heard much from them. “The enclosure sits on
