“…In this project, we use MOSFETs because of their high switching speed and low RDS resistance for low heat dissipation. H-Bridge configuration requires both P and N type MOSFETs but since N-type MOSFETs have improved electrical characteristics, using only N-type for four of the transistors will be ideal…”

“I find the CPU/Memory/HDD/Net stats as something I regularly take a look at. But these stats live a virtual life….The desire to somehow free the stats from their virtual world and have them on my desk is what made me create the ReCoMonB – Real Computer Monitoring Block.”

“The SudoGlove is a gesture controller that can be easily interfaced with hardware or software via a wireless connection. The glove implements an array of sensors plus filtering circuitry and mathematical analysis firmware to derive state values for each sensor and transmits them to an authorized receiver.”

“We decided a few weeks ago to use the Android as a remote controller instead of building a remote control from scratch. We had started developing our android controller with Google Labs App Inventor but one of the guys over at LMR did the same thing and put it on Android Market for $2. So we decided to use Chris the Carpenter’s RocketBot Controller.”

“This is an article from an electronics amateur, experienced in embedded design and programming. He has utilized the BPS-5-3 breadboard power stick, LC04A Logic Level Shifter and WIZnet Serial to Ethernet Gateway, to show a basic interface between WIZnet gateway, Graphic LCD, PIC microcontroller and the setup.”

“My wife recently asked me if I can make a digital clock from all the microcontrollers and electronic parts I’ve been playing with. She wanted to teach our son how to read the clock, and so she goes, ‘if you can make something useful out of your hobby, I’ll be pretty impressed’. :-O them challenging words..”

“Craft is a demo running on its own minimalistic demo platform. The demo platform is based on an ATmega88 microcontroller. Having successfully built a soundchip out of a microcontroller together with my friends in kryo, I wanted to tackle the greater challenge of generating a realtime video signal along with the sound.”
