We have seen how transformers are made before but how do they actually work? Fileark gives us demonstration video about the magic that is happening inside the transformer. “The transformer is based on two principles: firstly, that an electric current can produce a magnetic field (electromagnetism) and secondly that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil (electromagnetic induction). Changing
Most of us have used high power LEDs in our projects. It’s getting quite common to see 1 Amp LEDs used for lighting applications. Even though when you normally think about LEDs you envision something that is cool to the tough these high current models need heat sinking to keep their die temperatures at bay. Our friend Carl from Sweden has been doing some experiments with a super high power
Andres Guzman-Ballen, a Senior at the University of Illinois studying Computer Engineering sent us an email about his latest project. It is a Wireless Electric Mountainboard. You can see the video below of the hard wired version that he built when he wanted to debug some issues he was having with the wireless setup. “I chose a mountainboard because the truck design allows the rider to carve more since the
Fresh off the assembly line… We have a new kit that is being released today. It’s a universal IR Jammer which can be used to jam any infrared remote control device. The Infrared Remote Control Jammer allows you to render all IR remote controls inoperative! The microcontroller in this design allows for all 6 of the main IR frequencies to be targeted making this unit universal. It works by corrupting
I thought I had seen it all. If you want to do some scuba diving this is not the way to go about it… Some ideas don’t need to be invented. It looks like the user is tethered to a boat on the surface and probably just hangs on for the ride. It would have been so much better if it was at least an underwater motorcycle.
If you have ever wondered what the inside of a TV Factory looked like you are in luck. Looks like there is very little brought into the plant in a finished form. Everything from the styrofoam packaging material to the plastic housings are made in-house.
Automated robotics is has always fascinated me. Kiva Systems makes a Robotic Warehouse system that is simply amazing. Just imagine not having employees needing to go out to shelves to retrieve product but rather have the product come you the employee. That is a cool concept but it does take a ton of technology and equipment. I have always wondered how long one of my Mouser order takes to get
