Welcome to my blog where I share thoughts and insights on technology, startups, and life in Atlanta. Browse through the articles below or explore by topic.
G-G Surface Generation
June 19, 2012
Note: This post has been migrated from my old WanderTech blog. The original post contained example G-G surface plots which are currently missing. I’ll update this post if I can track down the original images. The G-G surface is a scatter plot showing all accelerations generated by a car or bike in the longitudinal (forward and back) and lateral (side to side) directions. They can be very useful i...
Introducing WanderDAQ: Versatile Arduino Data Acquisition
June 19, 2012
Note: This post has been migrated from my old WanderTech blog. The original post contained various product photos and diagrams which are currently missing. I’ll update this post if I can track down the original images. The WanderDAQ shield plugs directly into the Arduino Pro 3.3v board, and can collect data from any analog sensor in 2 different ways (Over serial or on a microSD card). The Pro’s 6...
Parameter Estimation with Virtual Elevation
June 19, 2012
Note: This post has been migrated from my old WanderTech blog. The original post contained various screenshots of the Virtual Elevation software which are currently missing. I’ll update this post if I can track down the original images. Virtual Elevation is a parameter estimation tool used to estimate constants associated with any dynamic system. Using Monte Carlo Methods and some proprietary opt...
Introducing AutoChung: Estimating Cycling Aerodynamics
June 15, 2012
Note: This post has been migrated from my old WanderTech blog. I have posted ad-nauseum in the past about parameter estimation, conference papers, bike parameter .exes and noise like that. It’s finally starting to be pretty concrete. There is now an overview of an early stage desktop application (maybe a webapp down the road) to estimate drag coefficient and coefficient of rolling resistance usin...
Miscellaneous MATLAB
June 10, 2012
Note: This post has been migrated from my old WanderTech blog. The original post contained various code snippets and examples that have been reformatted for this version. For whatever reason I have ended up doing a large amount of work in MATLAB. In school, with controls and simulation projects, prototyping for personal projects, and some finance work back in my glory days. Throughout all of it, ...
Mastering Data Acquisition with Arduino
May 29, 2012
As part of a larger project, I needed to gather some data remotely. In my case it was accelerometer and frequency data from a reed switch. Either way, I needed a robust way to log data from a variety of sensors onto a memory card of some kind remotely. I decided that the simplest way was probably with Arduino, and quickly hacked together something that worked well enough on a breadboard, then took...
Reflections on Bike Racing: Lessons from the Road
May 18, 2012
Note: This post has been migrated from my old WanderTech blog. The original post contained various photos from bike races that are unfortunately no longer available. So this blog is mostly intended to house my projects and engineering related endeavors, but I wanted to do at least one about bike racing. Racing has taught me a lot of mostly decent things, with a few admitted bad influences. Throug...
Home Again: Rediscovering Georgia's Trails After Racing Adventures
April 25, 2010
Note: This is an old post migrated from a bike racing blog I had for a time, GHBRA, or the Georgia Homeless Bike Racer Association. It was a pretty infromal log of our travel and experiences racing bikes as teenagers. So after 22 days on the road and couches/air mattresses, I have finally come home, and to amazing weather no less. I managed to get back to some singletrack, which was cool: Jack ra...
Conquering GMR: A Cyclist's Journey on Glendora Mountain Road
March 23, 2010
Note: This is an old post migrated from a bike racing blog I had for a time, GHBRA, or the Georgia Homeless Bike Racer Association. It was a pretty infromal log of our travel and experiences racing bikes as teenagers. So after being humbled in spectacular fashion at San Dimas, I found myself with an unexpected day off. Of course I had to go find the top of Glendora Mountain Road, and almost 2 hou...
Cycling Adventure on Glendora Mountain Road
March 17, 2010
Note: This is an old post migrated from a bike racing blog I had for a time, GHBRA, or the Georgia Homeless Bike Racer Association. It was a pretty infromal log of our travel and experiences racing bikes as teenagers. So I got to ride without leg warmers today. In fact, it was in the mid 80s, not a cloud in the sky, and downright pleasant. The ride for the day was to wander up the Glendora mounta...
