Kiteboat Logger Power Control
Return to News
We can now start and stop the kiteboat logger and verify that it is powered on without opening its protective waterproof case or connecting from a remote device. This has involved running the power switch and LED from the internal PC to a waterproof switch on the outside of the case, a job which was made trickier by the miniaturization of the PC. This operation also opens the way to making an external supervisory circuit that can control the PC power and monitor the battery state on longer excursions.
Other recent improvements to the logger include auto-detection of removable media, software to assist with calibration of the wind sensor while we are on the water, and an independent charging port. When a miniSD or USB drive is attached, the logger automatically writes to log data to the external device, and we are working to make it possible to directly import the data into the KAIView software. This will make it considerably simpler for anyone to operate the logger and analyze test results.
