Went over to the greenhouse to tighten the fan belts. This didn't work so well - both belts on houses 3 and 4 have no more adjustment left. I found a fan belt in the garage that's 55 inches. I looked up what we've been using and it's anywhere from 53 inches to 55 inches. Took 2 barrels of dirt home from the greenhouse then worked some in the backyard. Put three wheelbarrows of clay at the base of the oak tree filling in stump holes. Walked to the top of the hill to check on the bird house - a pair of bluebirds are building a nest up there. The septic pumped this morning - there was another puddle at the base where the pipe was drilled. Dinner was chicken and broccoli with curry simmer sauce. After dinner we read our books and listened to WCPE playing the Chicago Symphony performance of Holst's Planets. This morning the Bonnard card arrived - everything fits mechanically!!!! Put the card together but did not power anything up yet. I ordered the missing voltage regulator resistor along with other parts from Digikey. In the meantime i will jump out the regulator and run the thing directly at 3.3 volts.
