Rick Hoadley (the Magnet Man) has put together a simple gaussmeter project that uses a hall effect sensor to measure magnetic fields. The video shows two meters, one that uses a PIC microcontroller to measure and show the values and the simple version. There is no plans for the PIC version that I could see. Perhaps if there is enough demand Rick will make some plans and code available.
Do you have too many remotes in your house? Well a few more can’t hurt, why not install a few of these LED lights that come with a 24 button remote control! With features like strobe and disco this device could double as an epileptic detection machine. “Specifications: – Led bulb to save energy – Over 15 colors (including white) to choose from – High/Medium/Low switch – Around 2.5 meters
Christopher Conte has created some wild pieces of art. I think the Robotic Needle Injection Machine is my favorite though. This would be great blown nice and big and hung in the lobby of my doctors office! What is your favorite? “Christopher Conte was born in Bergen, Norway where he began drawing at age 3. At age 6, shortly after moving to New York, he started taking college art classes
If you have ever wanted to build an underwater camera cheap this is a great project to reference. The Shark Cam uses a tiny security camera, some PVC pipe, duct tape and some other odds and ends. “Last year while shark fishing off the Dumbarton Pier and recording the catch on a 20 year old VHS camera I had an idea. I thought of how cool it would be to
Looks like there might be a breakthrough in x-ray technology very soon. This article is from the free Electronic Products magazine that is one of the Hacked Gadgets engineering magazines offered. “Removing a major obstacle in the quest to build a tabletop x-ray laser that could be used for biological and medical imaging, a team of researchers at the University of Colorado at Boulder has developed a technique to generate
It seems like everything in this hectic world is going digital. This Wireless Router with Analogue Utilization Meter project takes digital information and presents it in an analog form. Video after the jump. “There are a number of ways to find out how much bandwidth is being used. This being the first pass at a digital to analogue conversion of the utilisation, I opted for simply using the uplink LED
Guido Socher build this Ethernet Weather Station project that uses an AVR microcontroller to process data from weather sensors. Software and schematics are provided. “Using an add-on card to the already existing avr ethernet board we build a weather station. That is a weather station with a build-in webserver. My original plan was to have sensors for temperature, air pressure and wind. I started a prototype and it worked very
