This was a 2 different Lowes day. In the morning I went to Lowes N Cary to get light fixtures. I need 4, they only had 2. Picked up some plumbing parts to work on the Tower Irrigation. In the afternoon Libbie went with me to Lowes at Crossroads where we got the two remaining light fixtures. We also stopped at Walmart in Apex to get containers for flour and rice in the cabinets. Finished up the remaining 2 lights. Tower 2 is completed with the exception of purchasing light tubes and building the power cord. I studied the needs of the controller for the tower and decided that in order to get 8 moisture sensors on a controller I need to build a custom PCB with relay switching of the sensors. This same controller will operate solenoid relays via a one wire interface to a Hobby Boards relay board. The dilemma is what to do for communications. I want to use a wireless Xbee but am unsure if i can get this working before we leave for Florida Sept 28. If I use RS485 for communication I will need to run wires. The Xbee however requires a 3 volt interface. Dinner was pork chops, sweet potato and apple sauce. We had a bottle of shiraz with dinner. The end of Labor day and the end of summer.
