“I have a computer in my apartment which I mostly use for playing video games, but sometimes I like to access it remotely over the internet to do server tasks for me. The problem though is that gaming desktops use a lot of electricity when they’re running. So running the computer 24/7 would be too wasteful. Instead, I want to be able to turn on my computer from anywhere on the internet; whenever I desire to use it remotely.”

"My inspiration for developing this gas gauge was after purchasing a new car (Scion Xa) and wondering what MPG I was getting. After much research on ODBII protocols, and looking into open source software that already existed I delved into my first Arduino project."

"So what can one do with an ATTINY-85 and no other external components, an 8 pin package that leaves ONLY 4 IO lines after you feed it a clock?? How about 4 color rock solid VGA with stereo sound!!! I kid you not, with only 4 IO pins, this little AVR pulls it off."

"This is a motor driver board that can drive 2 DC motors in Forward or Reverse with full speed control. It can handle at least 25 amps per channel continuously at 24vdc. I designed it using a basic H-bridge with 4 switches, 1 switch going to positive (+) and 1 switch going to negative (-) for each motor terminal."

"A simple single-sided board that connects a RS-232 serial port to the Raspberry PI and breaks out some of the PI’s pins for experimentation. The interface board was designed to be simple and used for initial experimentation. It can be built on a single-sided PCB using home-made PCB fabrication methods."

".Anyway, Luke Miller over at FPGA Expert recently bought a vintage pickup truck and wanted to trick it out a bit with some custom electronics. He decided to use GPS to measure speed rather than hooking the speedometer directly up to the truck’s sensors, this way the project could be replicated on any make/ model of vehicle. Luke is using a Pmod GPS receiver which he is then running through his Basys2 Spartan-3E FPGA board to make this thing work.quot;

"Raspberry Potter is an open source project that lets you control things around your room or your house with a magic wand. Imagine if you had a magic wand to control everyday things. Once you make a Raspberry Potter, you’ll be able to do just that – by drawing simple gestures in the air."

"I have recently moved to a new apartment and was looking for a PWM dimmer to control some 12V LED strips. I thought that should be easy enough nowadays but it proved more difficult than I thought. All I found either didn’t meet my requirements, were uggly or expensive. So I decided to build my own, tailor-made to my needs."
