I have made use of the software to be found on the Embedded Linux Wiki website. The page detailing the software is to be found here. This seems to be an really neat program and I have nothing but extreme admiration for the people who spend a great deal of time and effort developing such good stuff and make it available for free to programming simpletons like myself!
There are so many features and subtleties that , so far, I have just scratched the surface! The software serves up the live camera feed and it may be viewed by logging page at the RPI’s address on a browser on any platform!
Below is a screen shot revealing a small section of the settings menu available. Clicking on the image gives a full screen view. You can take a still or a video at any time and download it.
Below is a screen shot of a more developed program running on the Pi, written in Python/Tkinter. The radiometer and the wind speed/direction units are plugged in. The various parameters are displayed using the dial gauges written by Roger Woollett. Clicking on the gauge title buttons resets the high and low values.
The nine buttons used to move the camera pan and tilt are bottom right. Pressing the “En” button turns the pan/tilt system on and off. As mentioned previously, unless the power to the servos is turned off (which is what the En button does) the servo can jiggle which can make the camera image unviewable. This could be spurious signals generated by the Feather or a problem with the rather elderly servos. I haven’t that investigated yet.
Below is a downloaded still from the camera. I have lightened the shadows using Photoshop. The dtail is quite good but not quite good enough to tell whether the tomato plants in the bed are slightly wilting. However, it is probably good enough to see whether the automatic watering system has sprung a leak and is flooding the greenhouse!

This is a view of the Pi remotely viewed on a PC using VNC. Life would be a lot less fun without it (alternatively, I should get out more!)
