"…I decided to look into capacitive touch buttons. The big issue unfortunately for me was that you usually need a separate chip for capacitive touch sensing. With some tricks, you can however use a normal microcontroller to do the job. Even using only a single pin and resistor."

"The Micro Framework is one of the newest kids on the .NET block, but it does something really rather wonderful. It brings embedded development within the reach of any C# programmer. If you know C# and love Visual Studio, you can now get started building hardware and controlling it with your software. Moreover, it lets developers achieve one of their most cherished dreams, to control their festive lights using programs that they have written."

"We have designed a biometric sensing computer mouse that takes into consideration heart rate and galvanic skin response in order to detect the different conductance of the skin when a person is under stress or when not. In order to stimulate stress, we invite the user to play the Falldown game. As the user is getting closer to the end of the game, his/her stress level is expected to increase, the ball will start to move faster and the game stimulates the user to increase his/her concentration on the game."

"I wanted to make use of bluetooth capability somehow, and thought it would be neat to send a text message to the display. In addition, I decided change up a few things: receive bluetooth text message up to 64 chars and scroll it across the panel, set the time via bluetooth, consolidate 2 push buttons into 1 for manual time adjustment and make some noise with the piezo I put in there"

"Last week I finally got time to do a bit of work. I made my own PCB :). I wish I had learned this back in college. It have would saved me so much time. What PCBs did I make? An improved line follower circuit."

"Have you ever seen videos of those insane Christmas light displays? Those displays are usually controlled by large banks of solid state relays turning on and off each strand to time with the music. I bought a bunch of these relays on eBay and wanted to make my own general purpose controller that I could use in other projects."

"I wanted to create a truly personalized one without ruin me either. Two ideas immediately came: a microprocessor to control all the lights, but at the cost of a relatively large strand wire, even though the use of crossing wire and diodes, can reduce the number of son, this is not very satisfactory and place a microprocessor per lamp, but until the price of each processor exploded the price of the most basic garlands."

"Today’s tutorial is a bit different: I’m going to show you how to make your ethernet shield wireless! You can find many Wi-fi shields for Arduino: starting from the official one, up to shields based on Microchip’s ICs. Sometimes however it could be easier to connect an Arduino to the Wi-fi network using your ethernet shield in conjunction with a wireless router."
