After a couple of frustrating days trying to get the SPI interface to work, I ran across a post by Brett Wilson about using the shield with an I2C interface.
In his post he plugged the shield into a proto-board. I wanted to keep it attached to my FezPanda (.NET Micro, Arduino clone).
The attached PDF details the hardware mods to use the shield with the I2C interface. I will post NETMF C# code soon.
I’m finally getting around to working on the anemometer. I had originally planned on building an ultrasonic anemometer but finding a source for the transducers is proving to be quite difficult. Instead I’m going to build my version of a “rotorvane” anemometer (original can be found here).
Doing a bit of software development today. I have found an occasional error coming from the temperature / humidity sensor. It will sometimes output a value a few hundred degrees below actual temp. I’m working on an algorithm to trap and discard the bad data.
This wonderful little piece of metal helped me start off my day in a wonderful way.
It managed to embed itself in my tire all the way up to the little bolt.
Wow, less than one day. That is all it took for spammers to find this blog and start submitting comment spam.
I’m currently working on my weather station. This has been a work in progress for several years and I’ve finally taken the time to actually build it.
Currently it only has Temperature, Humidity, Barometer, and a partially working rain gauge.
The rain gauge is being problematic. It randomly has stay counts. I need to work on that next.
