Do you know if you can trust GPS? I have a proper antenna mounted on my roof and position captured with a survey gps. This is connected to a gps sending data to gpsd, calculating horizontal and vertical error, and feeding it to influxdb. There i can easily graph and create alerts. #trustbutverify #collectyourowndata

My old weather station shield made in 2008 from plywood and epoxy has finally disintegrated. Printing a new one piece by piece. #3dprinting #collectyourowndata
