"Intrinsic optical signal (IOS) imaging is a functional imaging technique that has revolutionized our understanding of cortical functional organization and plasticity since it was first implemented, around 30 years ago. Even if IOS imaging lacks the ability to directly measure electrical neuronal function and track data at a fine temporal scale, it has some advantages on electrophysiological techniques, such as the capability to visualize functional architectures via the simultaneous sampling of a large cortical region with high spatial resolution."

"Libraries are files written in C or C++ which provide sketches with extra functionality, for example the ability to control an LED matrix, read an encoder, connect to a sensor, display, or module, etc. They are very useful to lower the barriers for creating amazing interactive projects and use a wide range of components. Libraries can be created by everyone and shared with the open source community!"

"My system doesn’t require plumbing alterations, and it transmits the information via my home wireless network, so I can view water use on a connected device anywhere in the house. Now when my teenage kids take profligate showers, I can berate them with quantitative measurements!"

"Remote garage door openers are great but there were times I need access to the garage and did not have the remote with me. I therefore designed a simple keypad with 4 digit access codes to allow myself, my family and friends to gain quick access to the garage when a remote is not at hand."

"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."

"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."

"In this post, I’m going to cover a new project I recently finished – creating a device that monitors a washer or dryer and sends a text message when it detects that a load of laundry has finished. Beyond the novelty and simplicity of receiving a text message when the laundry is done, I built this device for two reasons."

"Since ERNE was originally created as part of my Senior Capstone, I decided to compile some of the work I’ve done with the robot into a single video, along with some info of where this project has taken me."

"We designed and built a wireless computer pointing device with accelerometer based movement control. Our implementation allows the user to wear a set of hardware (a glove and connected armband) and control a cursor through different hand orientations and finger presses. Users can operate their computers with their hands in midair without the hassle of desks surfaces or wires."

"On this site we have published complete directions on how to make your own sentry gun, which autonomously tracks, aims, and shoots at targets…We are a unique project in that everything we do is completely open-source. This includes 100% of our code, as well as our electrical schematics, and even the CAD design files for our Standalone Controller. Our system has been used on six continents and in more than 20 countries (so far), and is even used by the Australian Navy in their training program."
