The boost converter is a DC-DC converter used to created an output voltage that is higher than the input voltage. Boost converters are also used to drive LEDs placed in series in products like LED flashlights. The boost converter suffers from vulnerability to a short circuit load. Learn how to protect them from shorts!

Tesla Motors was founded in 2003 and is an American automotive and energy storage company. This article will focus on how Tesla's Roadster electric motor works. The basics of the car are pretty standard and straightforward, but the intricate details are much more intriguing. It will also detail the key differences between an internal combustion engine and Tesla's electric motor. At just about the size of a watermelon, the motor converts electricity into mechanical power and also acts as a generator, turning mechanical power into electricity.

I hear about it all the time: planned obsolescence. People can't believe that their computer parts are already breaking and their iPhone started to slow down just days before the next generation of the phone was released. Your TV seems to be programmed to have bugs whenever the manufacturing company wants to push a new product. Companies break their own products to get you to buy more of the same product: light bulbs, phones, batteries, cars, microwaves, computer screens, and even your car key transponder will all stop operating eventually. Either the marketing team or the designers wanted it that way, right?

Qi (pronounced as "chee") charging is an optimized inductive charging concept also known as “wireless charging,” allowing you to charge your devices wirelessly. Compatible devices’ batteries are charged by using induction transfer without requiring separate chargers, cables or adapters... Simply place your compatible device on top of the wireless pad and watch your device charge. Finally--an end to cords!
