Here are some photos from the beginning of the month. Rick Wehr had called the flow diagram of the environmental methane sampling system that we will deploy in Brazil “The map to find Luke Skywalker”. If the diagram is the map, then following the diagram may be considered “Finding Luke Skywalker”. Left, pre-assembly of the calibration system manifold. Right, the completed manifold without the two-way solenoid valves. The system now has some working code as well.
