Unfortunately I've had to cancel the 10/17 class, right now the next class is tentatively scheduled for 11/14 pending confirmation of the room availability.
I'm also not happy with the light sensor so instead of the one we are currently using, we'll be switching to another one that has better range and functionality. I'll have them for everyone at the next class.
I'm also still working on the Raspberry PI documentation, they've just released an updated version called "Jessie" so I'm going to download it and work through the configuration using this latest version.
Thanks
