Arduino Wanderer v1


Back in April I got an Arduino Duemilanove and a variety of sensors and actuators, which promptly caused me to go order a rover base from RobotShop.ca, and a few days later, I had put this little guy together! Truly, Arduino is an easy-to-use platform for this sort of thing. I went on to put together an iPad-controlled version as well as a wireless Wii-Chuck-controlled version but I'll post about those later.

OpenMyEWB

OpenMyEWB

From October 2005 to May 2010, myEWB.ca was Engineers Without Borders Canada's official online community system. During that time, tens of thousands of people used myEWB to participate in thousands of online conversations, send millions of emails, schedule hundreds of events, share files, apply to serve overseas, register for conferences, pay their membership dues and otherwise collaboratively work towards eradicating poverty. As the team leader and major contributor to the myEWB project, I am proud to be able to host a small page for OpenMyEWB: the now-open-sourced software that powered myEWB.ca.

Context

Context

I always have trouble remembering what famous people were alive when, and more importantly, who was alive during, before or after who’s life. It’s easy enough to remember which philosopher came before which other philosopher or which scientist came after which scientist, but often harder to remember which scientist came before which philosopher etc. So I built a PHP script to automatically lay out an HTML timeline to help keep all this stuff in context. I then decided to learn how to use XSL and rebuilt my little experiment using that. Click here with a modern browser to open the timeline.

BitNorth 2009: myEWB

I did a 'short bit' presentation at Bitnorth 2009 about my feelings on myEWB and its history.

The presentation is available as PDF, PowerPoint and MP3.

PHPTab

PHPTab

The Problem

You're part of a small-to-medium group of people who trust each other and have some reason to spend time and money together (e.g. you have a few housemates or you work in a friendly office environment). It's a huge hassle to constantly be requesting separate bills or lending each other money and losing track of who owes who how much and for what. You waste time quibbling over small amounts and people in your group don't like lending each other money or picking up the tab for lunch.

The Solution

Using this simple web application, a group of people who trust each other can keep a running tab of how much they owe each other. This is handy for figuring out such things as who should pay for groceries next time (e.g. whoever owes the most) and generally makes people more easy-going about spotting each other money or picking up lunch, as they know they can keep track of it. With PHPTab, any member of your group can be as lenient or penny-counting as they want, without ever having to actually be constantly be trading small sums of money. It's just a matter of "putting it on their tab".

Bridge-Optimizing Genetic Algorithm in Excel VBA


In the fall of 2003, my classmates and I were given an assignment in our Bridge Design course, to model the Salginatobel Bridge as a truss and analyse it using the Stiffness Method in Excel (ignoring buckling effects). As an additional challenge, we were to be awarded bonus marks if we could improve upon the efficiency of this, our professor's favourite bridge, by moving the members around.
