I finished off work on the logging and telemetry software for my balloon test platform.

Work has been busy so this has suffered somewhat.

I have done some work around integrating a EM406A SiRF III GPS with an Arduino compatible and displaying the results on a 2x16 LCD.

I went to DEFCON XVII. Of course I took a camera, but screwed up and didn't set the date/time. I snapped a couple of hundred pictures, imported them into F-Spot and later realized that they were dated in 2005! Doh! Here is how I reset them to the correct values.

Do you use F-Spot? At some point you'll want to move all those photos to a different drive or directory. When you do, you'll want F-Spot to keep track of them in their new home.

Ok - been playing with a few toys, the latest being the ArduPilot

Well my time at Canaca is done. The hosting rates were not that bad - but it really irked me that a Canadian company would charge in US$ and then fix the exchange rate at 1.3 to get back to CAD$.

I finally took the time to figure out how to tether my laptop to my phone. Yeah - I know, lots of people have done this but I couldn't find a straight forward walk through for my scenario.

You can find the walk-through here: BlueTooth tethering Ubuntu 9.04 to a Rogers N95

Today I spent a couple of minutes to add a read of the accelerometer and display it on the LCD. Not much to this really, code and pretty picture here: Displaying the Accelerometer

I'd read several articles that referenced data logging for model rocketry which I found really cool and interesting. I thought: Hey - I've got some accelerometers, PIC micros and other assorted uC detritus - I can do this!

I went to my electronics bench noted the dust on everything - I need to spend more time here!. I grabbed one of my PIC development boards and a 2D accelerometer (DE-ACCM2G).

Well it's now Monday after COSSFEST - all the hard work of everyone involved went towards an event with some excellent presentations!
