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 ...

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 ...
