This instructional video shows how change traffic lights from red to green, using science, and without actually having to know anything about magnetic fields or properties! Save gas, time, and frustration in your car and during your commute! Works great! See the test results! ...more
This is the third part of my electromagnetic pulse series (see Part One and Part Two). By now, I've covered the hardware and general concept of electromagnetic pulse generators, but how exactly do they disable electronics? How can an invisible field of energy have such a catas ...more
How to find your direction without a compass if you are in the Northern Hemisphere. Find cardinal points with an analog watch. It's more effective than a compass, because it's not affected by the earth's magnetic fields.
The widely used expression "free as a bird" intimates an enviable existence: delicate, yet mighty wings transporting to destinations no human could so breezily venture. But despite their fanciful, superhero ability, in truth, the avian race leads one of the most difficult exis ...more

Hello again, fellow hackers and electrical engineers! As many of you understand by now, knowing electronics is not really a required skill for hackers, but it will most certainly come in handy and may save you a lot of time! But before we can design cool circuits like an EMP ...more
It's time for a 'science is fun' video! Bar magnets put in a DVD case show how combined magnetic fields can be used to hold another magnetic object in place, even when it's an inch or so away from the actual magnet. You can even get mangnetic sand (iron, etc.) from the beach!
Want to learn about magnetic fields? Sometimes the best way to learn is through visual representation, and this video shows you some funs ways to manipulate and view magnetic fields in action using a large horseshoe magnet, a steel keeper, plexiglass and some iron filings. Fi ...more
Michael Faraday was awesome. He discovered electromagnetic induction, diamagnetism and electrolysis, and he invented the Bunsen burner (before it was the Bunsen burner). Because of his work, we can make suits that can withstand 1,000,000 volts of electricity and cases to prote ...more
Are you lost? This how to video teaches you a simple way to turn your watch into a compass. An analog watch is even more effective than a compass because it is not influenced by the earth's magnetic fields. You'll never be lost again as long as you have an analog watch with you.
Maglev trains. Why are they so cool? Well, for starters, they float. The idea of levitating trains have been around since the '60's. The first commercially available levitator was introduce in 1984, Birmingham, England. The fastest known floating train is Japan's JR-Maglev, ...more
This is a running demonstration of the water-pressure powered Tesla CD Turbine III and Magnetic Coupler, running smoothly and safely at up to 1000 rpm at the sink. The CD Turbine is made from recycled CD's and neodymium magnets. In this video, the Magnetic Coupler is seen lev ...more
Virtual, mixed, and augmented reality all provide different but compellingly immersive experiences that draw us in through sight and sound. But what about our other senses? A few strange inventions are already exploring the possibilities. Adrian Cheok, professor of pervasive ...more
