Excellent idea. I don't have the Indi Dev experience to contribute but a couple of ideas on the hardware:
1. Add an external Wi-Fi antenna (signal strength seems an issue for my RPi inside a case
2. Fan location/position: dew falls downwards so ensure the airflow is drawing in from underside and expelled ideally through a side?
Yes, don't get me wrong, I'm interested with this "as-is", but as we're still in the stages of design, just thought that some suggestions might still be worthwhile. Even if it is space internally to house a 2.5" SSD SATA, and a hole (perhaps with a blanking plate) big enough to loop a USB cable back internally.
It does not need to House a full 2.5” SSD, there are much smaller versions available, like the M.2 or the mSATA drives, both much smaller....
Stellarmate OS on Raspberry pi4b
Skywatcher EQ8 pro, on steel pier
Takahashi FSQ85, FS60cb & Meade 8” SCT (de-forked)
Starlight Xpress SXVR H18, SXVR M25c, Lodestar x2 Guide Camera
Pegasus Ultimate Hub V2 for all USB & Power
Pegasus focus motors on all scopes
So the idea is really good, first I will do some small updates on the current design to prepare it for assembly with an SMD machine.
SSD, M2, or such drive would require a bigger design change, but this point is on the improvement list, thanks for the feedback!
That is a good idea, but unfortunately, currently, the Raspberry design has no option to connect an external antenna, maybe to hack the RPi would be possible, but one of the main points was during the development is to use the RPi as is, then everybody can attach it.
That is a really good point, currently, the GPS and the fan are on the same side, and to use the internal GPS antenna the top of the box should point upwards.
