Recently I had a discussion with someone from the South Riverdale Community Health Centre on Air Quality monitoring in Ontario (AQI). I learned a number of things, there are only 40 Air Quality Monitors in Ontario and they test for six key indexes. Toronto runs a slightly different test, the ...

Recently I've been experimenting with online coding tools, wonderfl and Bespin. Essentially both are IDE's enabling you to write code with syntax highlighting. Wonderfl enables coding for the Flash environment, while Bespin works in the HTML/JavaScript spectrum. There's some pretty immediate differences, Bespin is an attempt at building an environment ...

After a round of clarity (read: beer), Noel thought up a good way of maximizing the EEPROM memory in the data logger. Unfortunately it didn't quite work, I'll demonstrate below.
To reiterate, the RPMs I was recording off of the Hall Sensor would increase to a rate of over 255 revolutions ...
Lately much of my work has been dealing with getting Flash to talk to the Arduino. There's no real functionality to do this on its own, so you have to rely on some other components to host the conversation. There's a whole host of methods you can use here:
Socket Connection ...

Playing with code is fun, but when you do it all day for work it's nice to come home and build something tangible. I picked up some scrap Hard Maple from the baseball bat manufacturer that happens to make Barry Bonds' bat of choice (purportedly). Now ...
When I last left the data logger project off I was having quite a few issues with managing the size of the data in the allotted EEPROM space on board the Arduino. I built up an SDCard writer based on several specs I found in the messageboard and it worked ...

The Arduino EEPROM is a useful thing to have available for those times when you need to store small samples of data. In my initial data logger prototype I managed to record the Hall Sensor data into two bytes worth of space per minute interval. This gave me around 4.25 ...
I made the first successful run with the data logger yesterday. I've wired up a hall sensor to the wheel of my bike and recorded 60s intervals of my ride into work and back. Ideally I'm looking for increased resolution over a typical bicycle computer; where a ...
Been working on a data logging application lately with the intentions of recording my biking sessions and displaying them on a mapping API. The general idea is to use the Hall sensor common in many RPM applications to record revolutions to the EEPROM onboard the Arduino.
I'm having a few issues ...
I've had the Solenoid project working for about a week and a half now, but the rain and lack of sunlight was getting in the way of making a video of everything in action. It worked out well because it gave me the chance to demonstrate the project to a ...
