The anemometer for autonomous buoys is now functional

The first version of the anemometer is finished. Positioned on one of the autonomous buoys, it allows the wind speed on the body of water to be measured and transmitted to the remote display, which is located at the level of the radio control of the boats.

The wind speed display is shown in real time to compare boat speeds to wind speed. Pressing the "Record" button saves the data to an SD card for later viewing.


On top, the anemometer has a magnetic switch, which allows it to be turned on and off without any sealing issues.


When opened, the anemometer provides access to the various components, including its battery and USB charger.

Planet clicker unblocked came up when I was searching for something to play during a study hall period. The interface is fairly clean, upgrades and stats are separated clearly enough that nothing feels confusing. Tried it on the library computer and it ran fine, no lag or crashes during the short session.

Does this setup capture speed and direction or only speed? Could this low cost speed and direction sensor be integrated with the tech? It seems so as the sensor uses Hall Principle so should just output a voltage for speed and another for position. An electronic compas would also need to be integrated to calculate wind direction relative to buoy (and sensor) orientation and output true wind direction. A starting marker with speed and direction sensor would allow for precise course adjustment. https://es.aliexpress.com/item/1005010408060710.html

This setup detects only speed but all the buoys position themselves in the opposite direction of the wind, linked to our asservisment strategy. So we have the wind direction on multiple location of the regatta course. We record all these information for replay. I prepare a video showing that.
