Windsond graphics

So far I haven't talked much about the computer software that controls Windsond and visualizes the data. The software is still not completely polished but I can give an idea of what it looks like. For each launched sond, there are three views. The first view shows individual data updates from the sond and gives control over sond settings such as detach altitude, radio output power, LED blinking and loudspeaker output. This part is receiving an overhaul right now so I'll show a screenshot...

After the Balloon World Championship

The Balloon World Championship is over and I've made my way back to Sweden. It was a great experience and I'd like to thank all the people that made it possible. The locals were also very hospitable and cheerful. Windsond worked out well. It provided detailed wind readings to an altitude of our choice and immediately provided the pilot with a clear visualization. When other teams gazed in concentration on a pibal forming a dot in the sky, we could release a prepared balloon through the...

Balloon Worlds 2012

I'm now at the World Ballon Championships in Michigan, USA, helping the two Swedish balloons with weather observations using the Windsond system. It's a day and a half left of the week-long competition. It's a wonderous sight to see a hundred giant balloons suspended in the sky while the rising sun slowly dissolves the morning mist. So far we released eleven Windsonds. There's a lot of practical issues to consider and we learned some good lessons along the way. The first lesson was that corn...

Field testing Windsond

Last Friday evening we made the sixth field test of Windsond. We obviously already have some experience with it but this was the first test of the final circuit board and there's always usability kinks to work out. We connected the battery to the sond and closed the plastic bubbles that protect the electronics. The computer with connected radio dongle picked up the signal directly. The computer program made a sound every time a data packet was received to let us know the connection was good....
