Our friend Daniel Eindhoven from Megavolts found a great price on some huge used capacitors. These capacitors normally cost around $90 each, Daniel was able to pick them up for around $2 a piece! That is one hell of a huge capacitor bank on a nice budget. He also designed an interesting mechanism to tie the batteries together. Instead of using wire or busbars he designed a few laser cut
Remember the Tool Carying Robot that we featured here many months ago? Well there is now a new remote controller for that robot, the controller is universal so it can be adapted to control other robots as well. The design is based on a Parallax microcontroller and Xbee chips for communication. Thanks for the tip John
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
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.
Hacked Gadgets Forum member Alexander125 from Romania is using his ioBridge IO-204 to help him secure his house. “I’ve been recently working on a sistem to keep my house safe while I’m away.Using the IO-204 module I’m building a simple sistem to monitor power consumption in the house, movement(if there is any) using PIR motion sensors and the doors or windows. For the interface with the IO-204 I decided to
