“A while back, a few friends and me were joking about what people would do when all the sudden, instead of going back and forth, the cat’s arm would start moving sideways. The idea had been stuck in my head ever since then, and now, we’re about to find out. So, let’s hack a beckoning cat.”

“The purpose of this project was to create a simple, portable device that would periodically read sensors and then store the sensor data so it could be retrieved later.The result is the HexiLogger, ‘hexi’ because it can support up to six different sensor inputs and ‘logger’ because it will store the input data on a removable SD memory card.”

“Last Sunday I gave a workshop in TOG as part of its Engineer’s Week 2011 activities. We spent the day assembling an 8×8 Red/Green LED Matrix Display circuit which I designed in strip board. The circuit forms an interface between a micro controller and an 8 by 8 Dual Color Common Anode LED Module.”

“I took a class on digital controls at the UW this summer, and the class included a project option. I’d wanted to build a balance bot for a while, so this was the perfect opportunity. ”

“For the past two days I have literally lost my patience with Qik 2s9v1 dual serial motor controller. I have referred so many website and I could not make this controller work. After hours of searching I found this library which was compatible with Arduino 1.0…..Once that got the issue resolved I jumped into controlling the motor using a Proximity Sensor.”

“The piano box is a (somewhat polyphonic) paper toy synthesizer with 12 keys, each triggering a tone and an LED. The keys are a set of capacitive sensors, made of copper tape, controlled by an Arduino Mega running the CapSense and Tone libraries.”

“I present this new Arduino project: A full MP3 player based on Arduino.
As you can see in the photo, the idea was to build a standalone player, in the style of antique radios or ‘tapes’, in the age of Iphones ….”

“The device works by sweeping a grid of points and assembles the image piecewise. The output consists of two images: [1] an acoustic images which tells the distance to the objects in view and [2] a thermal image that gives the temperature of the objects in view. I use gnuplot to assemble the images.”

“What if you had the audio control panel, the dialog in most PCs where you fiddle audio, right next to your PC in physical form? With analog controls, VU meters and input/output selection present for instant access on your desk, you will have the pleasure of controlling them by hand.”

“The idea of this project was to design and construct a robot that consists of a body and two wheels that would be able to balance on its own. This behavior is similar how a segway (a new mode of transportation) works. Our goal was to have a working finished product – a robot that, without human interaction, could balance on two wheels.”
