There is a core description about the idea, the data flow, the need for the partner stations including some cost estimations. This is the content of EarthLAT1200_Project.pdf:

• aim of the project
• core meeting point
• data flow structure
• short outlook of a single partner station
• different contribution levels for partner sations
• estimated costs of a partner station.

A more detailed description of a partner station - here KEPLERUHR - contains:

• outlook of a single partner station
• HW/SW-structure
• configuration files for automated readout
• estimated costs of a partner station.

Different approaches to the design of the camera and housing exist. Within our experience there are some points of common interest:

• keep the housing waterproof from top, but allow for a hole downside for letting humidity flow outside
• protect the housing from direct sun radiation by a separated shield of e.g. aluminium - which also keeps hard rain/snow from falling to the housing/the lens
• the housing should allow for WLAN signal passing into it if connected wireless
• at Sdcam-Raspi there are two external temperature sensors: one for inside the housing and the second for outside the housing; prevent them from direct sun radiation
• the Sdcam-Raspi must be plugged via a electromechanical switch to power in order to power on before sunrise and power off ca. 30 min after sunset; The Raspi goes to HALT/OFF modus ones a day and therefore does not need to operate permanently.
