La Crosse Technology TX144W Wind Speed Sensor Troubleshooting

When the wind speed sensor fails, and it starts to groan, and the whole house echoes with it, it's time to have a look inside the unit and troubleshoot it. Join me to see how it failed. #engineering #electronics #consumerelectronics #arduino #robotics #weather #weatherforecast #lacrossetechnologies #weatherstation #atomicclock

Nice fix. I am glad you were able to save it from the dump!👏
What a drag to have to climb the roof just to change the dang batteries.
It needs a small solar panel and maybe a 3.7 V lithium rechargeable cell, perhaps harvested from a solar light?

Hopefully these bearings will last another season or two. You are right. Solar panels would work better, i’m not sure about lipo batteries though in a -20_F to +110F environment.

@@enginord No simple solution, I'm afraid. Our solar lights & automotive batteries take a beating here in the SW desert. CCA (cold cranking amps) are not much of a factor here!
Painting the housing/ battery box with white elastomeric roof coating may help.
