"In 2005 I spent a few months playing around with a persistence of vision (POV) circuit for a bike wheel. It was my first foray into electronics and micro-controllers so, while it worked, it was a hack."

"Often we don’t care about our posture which can result in back pain and worse. If someone tells you to sit upright this is easy to do, but it won’t hold on for more than a few minutes. Now wouldn’t it be great to have a device that can remind you to improve your posture?"

" I started generating concepts for a small robot late in 2007. Once I had finally settled on what I was going to build, work started on my robot in the summer of 2007. This page is devoted to the robot I ended up creating. Since then, it has undergone several revisions, reflecting my increasing knowledge and skills from my coursework."

"In this tutorial, I’m going to harness the awesomeness of Raspberry Pi to build a moisture sensor for a plant pot. You will be able to monitor the sensor locally on the LCD or remotely, via ControlMyPi.com, and receive daily emails if the moisture drops below a specified level."

"This project demonstrates the ability to navigate a user based on synthesized directional audio which allows the user to move to a known location without the use of a visual aid. The module uses a GPS, a digital compass, and an ATmega32 to generate sound based on the direction that the user must turn in order to face the correct direction."

"Designed and built during October 2000, this was my first ever microcontroller based project. This one was inspired by an Edmund Scientific instruments catalog. I didn’t see anything like this in that catalog but there were a lot of nice, year 2000 modern multipole cable testers, that made me think and imagine what would be the simplest possible network cable tester that I could quickly build."

"The objective is to use readily available ‘off-the-shelf’ low-cost consumer components where possible, and to design electronic subsystems where such components are either not readily available or are too expensive. In terms of affordability, the overall goal is to design a robot that can be made for around the price of a PC."

"Mister Gloves is a wireless USB gesture input system that enables a person to use a computer by performing intuitive hand and finger motions in the air. While wearing a glove controller on the right hand, the user can move the cursor by forming a pointing gesture and click by curling the index finger or thumb."

"As a result of building something for Red Bull’s Creation contest a team consisting of Jeff Waeglin, Chris Horne, Justin Griggs and Greg Needel (me) Built the ‘Pour Master Pro.’ The intention of this robot is to pour a perfect beer in any size glass automatically."

"Lately, I’ve been working with different sensors as part of my day job at TI. TI happens to have recently released a booster pack for the Stellaris and Tiva launchpads that contains (among other things) an accelerometer, a gyroscope, and a magnetometer. I figured I’d use my recent experience to do something fun with sensors in my free time :)."
