In the latest edition of Business 2.0 magazine there is an article about a company that is making underwater MP3 players. It is called the SwiMP3, I was expecting it to use something like watertight headphones or something simple like that. Well it actually uses bone conduction to play the music by vibrating your skull! Nothing is in your ears, instead the system uses cheek pads to get the vibrations
I have seen all sorts of remote controls, but I have never seen a cushion remote before. Only thing I don’t get is how can you use the cushion without accidentally pushing the buttons? “A new generation of remote controls: a bunch of different cushions each having its own function: one for the channels, one for the power, one for the volume and so on. These remote controls can be
Next time one of your gadgets breaks don’t toss it in the trash, engineer and construct a housing so that it can’t break again. At least that is what Russell Jones, an engineering student from New Jersey did! “The aim of this project was fairly straight forward. The keychain ring on my Corsair 1GB Flash Voyager USB drive from Newegg broke, which left the poor thing prone to be left
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.
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
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
Here is a simple design for a DIY metal detector that uses a beat frequency oscillator. “BFO ( beat frequency oscillator ) metal detectors use two oscillators, each of which produces a radio frequency. One of these oscillators uses a coil of wire that we call the search loop. The second oscillator uses a much smaller coil of wire, and is usually inside the control box and is called the
