roofing

It was too wet to get on the ladder this morning. It rained overnight and the tar paper was covered with water. Worked on the Tower Timer. The DS2408 seems to be unreliable with occasionally stuck bits which is not acceptable. Libbie needed some trays brought to the greenhouse. Went over there and looked at a rabbit hole in the back as well as a sidewalk with Joe's name and handprints in the concrete. Came back and started hauling shingles up to the new roof. This was killing me. By the end I was really winded and dizzy. Went inside and took a shower then started working on the timer again. I decided to throw the DS2408 chip overboard and wire directly from the AVR ports to the relay driver transistors. This seems to be much more reliable. I'm using the RJ45 connector that was going to be for One Wire and repurposing it for the relays. I can drive all eight relays with the RJ and use an external ground. Dinner was a bean burger. Talked to the Score card people about our missing score card. They said they will look into it.
