"PLC (Power Line Communication) is the technology that allows data transmission over the existing Power Line network. Power Line can be the home power network or the national electricity transmission grid. The data that can be transferred is as diverse as its speed. With speeds of nearly 200Mbps, video transmission, voice, data and any other services can be transmitted successfully."

"We are working to develop an open source hardware datalogger that can be placed in the field for extended deployments and measure common water parameters like temperature, conductivity, depth, and turbidity. There have been several iterations of the hardware, including a version based on an ARM chip."

"The controller uses an ATmega328P, the same as used on the ‘Arduino uno’. This makes it very easy to adapt the Arduino platform on the controller. You can upload your sketches via the usb port. The hardware and software is open for everyone, this makes it possible to program your own functionality into the controller."

"I will not go into details on how to control humidity. Instead I’ll describe what motivated me to design and create my own temperature and humidity sensor which reports its readings every minute to a central Linux server."

"This article describes how to build that wireless Bluetooth stereo audio system—one that’s also fairly low-cost—for outdoor use. The system, which maintains 20-WRMS output power, can be controlled either with a handset containing a Bluetooth connection and a music player or with an Apple iPod model."

"Basically, the system uses an accelerometer to measure g-force and a SD card to store the data. An Arduino UNO is used to process the data coming from the accelerometer and save it on to a SD card. The system was originally developed for setup tuning and performance optimization in RC cars."

"Ditch the key FOB and use your mobile phone as a passive key to access and authorize your car. There are many challenges with such a system but I believe this development is unavoidable. Whilst my prototype is certainly not the most elegant, it does proof a basic point, which is that dedicated physical car keys are a thing of the past."

"Who has not wanted to vacuum when being away from home? The technique I use is a hack to take apart the remote control of the robot and connect it to an Arduino UNO. To control the Arduino from PC via USB, I use Messenger and lets Eventghost manage all communication with Serial-plugin."

"This page outlines my project to home-brew a dedicated box for ‘tuning in’ these online stations…I wanted to make something to match the other stereo hardware I have. I also like that I can personalize every aspect of the design, and put to use some of the hardware I’ve collected over the years."

"Over a year ago I started to work on a small balancing robot. Between learning more about communication protocols and feedback loops I also had periods of schoolwork that kept me from this hobby. In the end my little robot was balancing on his own and I could send steering and throttle commands wirelessly."
