"A polar plotter is a plotter with a rotating, extendable arm. Its characteristics differ greatly from those of a traditional plotter, which in most areas have a superior design. You could say the polar plotter is more portable or something, but mainly I made this one because it was more of a challenge."

"So I had an idea…’3D RGB LED Pixel Cubes…’ *sweeping hand wave for effect*… I think that combination of words pretty much sums it, yeah? The basic idea is to take a traditional 2D pixel and turn it into a 3D form. I haven’t really seen this very basic concept… but haven’t Googled it to death…"

"People often use ARDUINO platforms and other microcontrollers (pic, avr) for making a propeller LED display and it is a bit costly to have them. I am trying to make one using AT89S52 microcontroller. I’m using a 11.0592MHz crystal and a 7805 for power supply. LEDs are connected to the PORT0 of the MCU, 8 leds are used for displaying letters….the wheel is attached to 6mm shaft and 1000RPM metal gare motor."

"Another piece of my ongoing FPGA stereo-vision project. This board is, as the name suggests, a breakout board for Aptina’s excellent MT9V032 1/3″ VGA image sensor. The board’s main purpose in life is to connect the LVDS output of the MT9V032 sensor to my FMC-LPC to SATA adapter board, which would then route the LVDS data into one of Xilinx’s Spartan-6 FPGA development boards. Multiple camera boards would be connected to support stereo vision."

"HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone’s headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation."

"In this project we are going to drive a single unipolar Stepper motor M35SP-8 (5 wire) using USB interface from a PC Computer. This project is an application of the USB Interface circuit PIC18F4550 which was published here in the past."

"The Gloves are a cutting edge experimental gestural music ware being developed today for the purpose of Imogen Heap’s studio and stage work. Using a unique gestural vocabulary, motion data-capture systems, and user interfaces to parameter functions developed by Imogen Heap and her team, artists and other users will be able to use their motion to guide computer-based digital creations."

"The Science Tricorder Mark 2 was a wonderful adventure of discovery to develop. It’s my pleasure to be able to share it with you…..The Science Tricorder Mark 2 was planned during Spring 2008, and actively developed starting August 2008 until December 2010 — largely over my fourth and early fifth years of graduate school."

"There are many methods capacitive sensors can be produced. A simple one way to form an on-off output is by using two layers and a spacer in between. Through a voltage to conductive objects causes positive and negative charges to collect on each object."

"This little project will demonstrate how you can build NEC protocol based Infrared Remote Control to use with various NEC Protocol IR receivers."
