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 flawlessly. I successfully captured RPM […]
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 hours of recording data.
What if you […]
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 low cost CatEye gives you average speed over the course of a total ride, I’d like to see how that average speed changes in increments. I recognize I wouldn’t be able to compete with a device such as a Garmin, but I could definitely improve on the $30 devices you get at bike stores.
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 getting the readings I need, namely […]
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 number of visitors today, all […]
My brother, Neil has been playing with an Arduino too. Here’s his latest script for controlling 3DS Max via Arduino:

One of the devices I’m most excited about lately is the MaxStream XBee. The problem with this seemingly innocuous little device is that it wouldn’t behave the way any other tutorial I found said it would. I’ve been working through three different sources of information on the XBee. The first was the source was the […]
