I spent a lot of the day working on the light sensor for the greenhouse. I can read the sensor, convert to footcandles and put the data out as a serial stream. I had trouble getting the device to work with the Xbee. The trouble turned out to be getting enough voltage to power the thing. I had to jumper the batt and input terminals essentially bypassing the battery charge regulator. While Joe and Libbie went to the Farmers Market I planted the butterfly bushes just before it started to rain which was a good thing and lucky timing. Joe made a lot of small and creative pizzas including a basil, a tomoat and a spinach pizza. He also made a BBQ pizza and a calzone type pizza. Lots of food. We had this with some Yuengling Black and Tan beer.
