Are you tired of having your Ni-Cad batteries that refused to charge and simply die? So what do you do with them when they die? Just throw them in the trash - which harms the environment? Or just take them to a recycling facility for them to be recycled? Well, here is the best solution, bring your dead batteries back to life that can save you a chunk of change - By zapping them! Here is one great instructable, Revive Nicad Batteries by Zapping with a Welder .

This java applet is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. The moving yellow dots indicate current.
You can use WEBENCH to create customized power supplies or DC-DC converters for your circuits. This environment gives you end-to-end power supply designs and prototyping tools. WEBENCH tools enable you to solve switching-power-supply design problems before you build your prototype. This alleviates the time and trouble associated with traditional power supply, design methods.

I’ve just returned from a week long trip to Shenzhen, China in a “geek tour” trip organized by Bunnie Huang , with some assistance from the fine folks at PCH International . More than just a tour, this was also a tiny conference of open source and physical computing hardware hackers. The participants were (from left to right above): Jeevan Kalanithi , Eric Schweikardt , Bunnie Huang , Nathan Seidle , Leah Buechley , myself (Windell Oskay), Tom Igoe , and David Merrill .
