"Here is my project on interfacing of SD Card. microSD cards are available very cheap nowadays, a great option for having a huge memory in any embedded system project. It is compatible with SPI bus, so the interfacing is easy. SD card adapters are also easily available in market, one can easily make a bread-board adapter by soldering few pins on it."

"While many POV projects have been designed before, they tend to be very static. Often they only display one image or animation and usually have no interactivity. We set out to make a very modular multipurpose design. Our original goal was to make two different LED arrays, a 2D version with RGB LEDs and a 3D version that uses monochrome LEDs."

"I developed this WSN for a coursework on my MSc and I’m hoping others will find this useful or at least interesting 🙂 I’ve just installed the first parts of this WSN back home to collect sensor data from various outbuildings and it will be part of my new Arduino controlled greenhouse project."

"One day a friend (who is also a Mechatronics engineer) and I decided to build an ultrasonic rangefinder. Sure, you can already buy modules such as the LV-EZ1 from Sparkfun, but where would the fun be in that? Moreover, things get expensive when you start wanting several of these sensors."

"I got all the basic Arduino tutorials running, so I decided to try my hand at something a little tougher: a digital “faradmeter”, ie capacitance-measurer."

"Trash Talk is a prototype for an inexpensive, mesh-networked, democratic public address system. Each node contains a speaker, a microphone, a radio, and an easy to use single-button interface. To send a message, simply walk up to any node, press the button, and talk."

"We’re exploring a whimsical project to collect breathalyzer data from various locations for use in visualizing local trends in intoxication. This weekend I completed the first step by prototyping simple hardware that reacts to various amounts of booze on the breath."

"LED Flowers are a set of PWM-controlled RGB LEDs which get their settings via USB using obdev.at’s USB stack. Everything needed for this workshop is under a free license, so feel free to copy and modify."

"Jonathan Ward from the MIT Center for Bits and Atoms has designed a snap-together, desktop-sized CNC milling machine. The MTM Snap is made from 1/2-inch high-density polyethylene (HDPE) – itself milled on a ShopBot – and can be assembled for about $700. This three-axis CNC machine can mill circuit boards, wax molds, and harder materials in a 5x3x1.75″ working area. "

"A PID controller is like a kind of fancy thermostat, but can be used to control pretty much any kind of process, not just heating and cooling. This project was inspired by the osPID and its design is greatly indebted to that pioneering device."
