Thanks for all the info. I just looked at the Raspberry Pi website and they say here http://www.raspberrypi.org/introducing-raspberry-pi-model-b-plus/ that, “We think you’re going to love Model B+, but to ensure continuity of supply for our industrial customers we’ll be keeping Model B in production for as long as there’s demand for it.“
It looks as if you do not need to redesign your board in the immediate future (unless you want, of course). Just specify that you only support the model B and not the B+. For OSPi there is no requirement for the B+ whatsoever.
SInce you are looking for feedback on the product, here a couple of thoughts.
1). One thing that I have done on my 1.4 enclosure is to drill a number of 1/8″ holes along the long sides with the intent of increasing airflow. My OSPi is mounted vertically on an outside, East facing wall in the waterproof case you suggest. Doing this has lowered the CPU temperature by about 5 degrees. It is difficult to measure this accurately since the weather here in Charlotte NC is currently highly variable.
2). Please consider a built-in update option in the software. A button in the Settings page that, when pressed, would go off and download and seamlessly update the OSPi (just your software, not Debian) without having to dive deep into Linux.
My OSPi is now becoming boring since all it does is to sit there and just work. This is a very good thing since all I want it to do is to water my yard.
Thank you for an absolutely brilliant product.
