A snapshot of the Exp1' hardware in bench testing configuration. At right you can see the finished structure awaiting anodizing and coating. In the middle of the frame are the HCX12 flight computer and the CC1000 radio. The radio is connected to a Ham radio (left) through an attenuator. Behind everything is our custom-built Ground Support Equipment that provides power, charging, programming, monitoring, and indicators.
In the second picture we have on of the Geiger tubes in the circular test harness pointing at a radioactive source in the center. We are trying to find the best tube to use in the spacecraft. The technique and equipment (amplifier and counter in metal rack at right) have not changed much since the days of Explorer 1.
