This post follows on at quite a distance from my last post on the subject, and until recently I had not realised quite how long this project has been languishing on the bench. Like many of the electronics projects I undertake they need to be able to withstand being outside and exposed to weather conditions,…
In this article I have a play with PyEphem and our local star, both as an opportunity to draw some pretty graphs and answer a few basic astronomy related questions, such as: what does the equation of time look like and is there a difference in the time it takes for the sun to set during the year.
This post follows on quite quickly (for me at least!) from my last one regarding my latest tests and reflections on environmental issues with some thoughts about how to measure ground temperatures in a reliable way. I am also going to take a look at the difficulties I might face in trying to automatically interpret…
Since the last part in this series I have continued to conduct experiments comparing and contrasting the two variants of MLX90614, the wide field of view BAA and the considerably more focused BCF. Whilst undertaking these ‘in the field’ tests I have also come up against a few, what you might call, environmental problems which…
This is the next installment on the cloud detection project. This time I am starting to test out hooking up an MLX90614 or two to an Arduino and try out pointing it to the sky in the aim of get some interesting results.
This project has its roots in a discussion I had a while back with a friend who is a keen amateur astronomer. He had been complaining to me about how he thought that there was a distinct lack of cloud free nights in our corner of Northern Lincolnshire. In fact, he suggested, the weather was…
