Hi,
Having discovered the world of Raspberry Pi type processor boards, I tried to experiment with the different components I would like to use for a mobile and autonomous observatory.
With the new RPi2 it became possible to install also Kstars under Ubuntu but this device is pushed to the limit as far as the available resources are concerned.
I power my mobile setup with a 12V car battery with 74Ah capacity but use the own battery for my DSLR and the Tablet used as monitor and keyboard.
For the time being the following services need to be provided.
1. A Hotspot Wifi network allowing my different components to communicate over the tcp/ip stack (RPi2, tablet).
2. Time service synchronising the clocks of different components. A stratum 1 ntp time service using the gps time signal from the high performance satellie clocks.
3. Indiserver integrating all services.
4. Kstars with ekos for controlling the HEQ6-pro mount including alignment and guiding (using indi features, astrometry plate solving or phd2).
For the future I would like to add a filterwheel, an autofocusser and first of all a filserver sharing discspace with Camera's, logs, configs, observation schedules etc.
Via gphoto I would also like to power my dslr on the single battery based 12V power supply and remot control it.
I would like to ask members of the forum about their best experiences with the different processing boards available on the market. RPi2, Odroid, intel PC, .?.
Which hardware is according your experience best performing for running the services you need for observing in an autonomous and mobile way?
Many thanks in advance!!!
Stefan
