Pulsar Kites Pulsar kite video It is fun to play with kites in Helsinki since there is a good wind current during most part of the year.
The interface has a wireless system that measure the speed and rotation of the kite, thus this data is transformed into sound on real time.

Guilherme Martins : The beginning of a Timeline. Arduino and watchdog timer. Have you ever encountered situations when your Arduino-based device hangs? There are many reasons for this - from millis() overflow in 49 days to moisture in outdoor sensors (causing them not to respond)... But what if your device is not easily accessible and\or works for long periods without human supervision? Such situations should be prevented in this case. You don't want your plant watering system that you left to look after your plants and flowers during your vacation to hang on the second day, leaving your loved plants without water, really? Most MCUs, including those used in Arduino, has a special feature, called Watchdog timer. Once it is configured, it checks for 'heartbeat' signals (or commands) that your MCU should issue. As soon as the time since the last pulse exceeds configured treshold, watchdog initiates reset sequence. I once encountered sudden hangs of my standalone arduino-based device.
I don't know, why there's not even a word about this in Arduino docs. Wdt_reset(); Practical Arduino: News. My Arduino. Motoruino | GUIBOT. Home | OpenEnergyMonitor.
