configuring ubuntu wireless there is nothing cool about a robot that needs wires plugged in — actually it vexes me to no end. running ubuntu in an embedded device can be a real pain when first setting up a new device. many robots are running linux on low cost itx boards these days and they all suffer from the same security hassle with initial network configuration. you just unboxed…

So, things break and need repairs. My Dad has always said.. “don’t repair, fit the spare”, but this part hasn’t been available a long time. I looked, made calls, sent emails, got calls back.. but no luck. The board is simple, just a few AC Power relays, but it is the controller for my bed and I needed it working as soon as possible. after an hour with the…

disk brakes for wheelchairs it’s been a braking with software (on board arduino or android). As a quadriplegic I don’t want to take my hands off the wheels to apply the brakes because this throws off my balance (especially on uneven ground or with muscle spasms to contend with). When adding power assist motors, a user must have the ability to stop even if that motor is malfunctioning. So…

wheelchair as a gopro dolly testing the camera on the seawall. this is simply the goPo handle bar mount attached to my wheelchair. I imported into final cut and shared to youtube directly. I did the colour balance step after a few basic edits. be sure to try it in different resolutions. the 720p and 1080p version look really good. youtube’s on stabilization took out most the bumps, pretty…

This page will hold data and evaluation of “boosting” experiments that I’m doing in order to get my heart and blood pressure to respond appropriately while climbing.  See ramp wheeling tests to learn more about post exercise hypotension (EH) , and why this limits performance in most quadriplegics.  First some background on what “boosting” is and why Doctors are trying to STOP this in sports. Basically put, Boosting is…

icord ramp fitness test I keep score of wheelchair races at ICORD. Here is an example video of Jaime and Brad on the ramp. This shows the difference between a T6 paraplegic (gold medallist) vs a C5 tetraplegic. You can record your own effort, or see the current statistics. current records: NAME ABILITY TIME CHAIR RECORD Pat Anderson Amputee 42 sec bb world record Katie Able Bodied 1:14 bb…

Networking with java These labs were written for UBC computer science in 2012. The content now has a few dead links and links and better ways of doing things, but they will get you going on java quickly. these labs go into details of using diagnostic networking tools and open source scanning software too. Lab1 — Introduction to Java Development Lab2 — TCP Sockets Lab3 — UDP Sockets Lab4…

a java based framework for sensors Zephyr Open is an open source code project to provide a framework for BlueTooth Physiological Sensors. Heart rate and blood pressure Monitors, gps and Wii Remotes are supported. What kind of mash-ups can you envision? Games for rehab? Distributed games and Virtual coaching? **This project is available on github, but has been replaced by by my tracks (google). With the framework is a…
