If by any chance you tried building KStars using "make -j4" or larger 'j' option, try running "make -j2" or "make" by itself. Smaller machines (Raspberry Pi, ODroid...) can't handle a high number of parallel 'make' jobs and exit with error after some time. I had it happen on me some time ago when I first tried to build KStars.

Mind you, I did not try buiding 3.5.3 but I built 3.5.2 yesterday. Was slow (few hours) but completed.

If you have the discrete version of the MLX90614 (not mounted on a board), as there is a 3.3 volt and a 5 volt version, you may not be operating it at the appropriate voltage.

The hard to read markings on the side should be MLX90614ESF-BAA-000-TU for the 3.3 volts part and MLX90614ESF-AAA-000-TU for the 5 volts one, or something similar (BAA - 3.3V, AAA - 5V).

Thanks!

I use an M,2 SSD connected vias USB 3.0 for storage.

Interesting! Did you drop the microSD and emmc to boot/run only from the SSD?

I got the same message, fortunately it does not seem to have an impact on the operation of the focuser.

I use the ODroid C4 with 64GB emmc on my C8 @ 2000mm and have most of the astrometry files for plate solving. It solves within a few seconds with the stellarsolver which is very nice. On your epsilon 130, it should be even faster as the solver should not have to go through huge files (small FOV).

Instead of

$ ps aux | grep indiserver
may I suggest using
$ ps aux | grep indi_
that way, you will know if indeed the indiserver is running, but also what INDI drivers are running thus, if indi_weatherradio is still/truely running. May help figure out the problem.

$ ps aux | grep indi_
is what I use to make sure my INDI distributed environment is functionnal.

Good luck

As I use dedicated focusers I can't help you with your specific focuser requirements but there is likely someone in the forum who can provide info.

You can look at this post from Jerry, it links to a document that may help you.

Nice write-up Jerry. Thanks for those who may want to try the ODroid route. One can also consider the newer 4GB ODroid C4 as a smaller (RPI size) and cheaper alternative to the N2/N2+ as, from benchmark, it is somewhat better than the RPI 4.

If I may add my comments (re: ODroid), I would like to add that I am running ODroids N2 and C4 for my 'transportable' observatory and telescope setup. The observatory runs a subset of the INDI suite (Dome Scripting Gateway, Weather Radio, Watchdog, GPS, DIY Flip Flat) on the C4, and the telescope runs the mount, cameras, UPB, astrometry, etc... on the N2, in a distributed INDI setup that I run from inside my house via NoMachine.

A big advantage of the ODroids I use is that they run on 12 volts with standard 5.5/2.1mm power connectors so, no need for voltage converters or special adapters to power them. Both have been working flawlessly, in our cold canadian winter, in < -20°C (-4°F) temperature for many hours, contrary to my RPI based observatory security camera that would not boot when it is -10°C or below. Another plus for the ODroids is that they generate less localized heat that the RPI as they have substantial heatsinks, making heat management one less thing to worry about.

Thanks again, from a "statisfied ODroid customer" :)

Regarding the new Polar Alignment Scheme and crossing the Meridian, my Avalon M-Zero OBS (with the motorized polar alignment system) went through the procedure without problems as it does not need to flip when it crosses the Meridian. It went from Pollux, across the Meridian, to an area close to the Pleiades, and the correction triangle help me correct in altitude very easily. I have a small problem with the azimuth control so I did not do the correction on it, but being about 20' from the Pole, I can live with that until the -20C changes to a more pleasant temperature so I can try to fix the problem.

Great work, thanks a lot.

I also use a "dark" filter for my darks and bias frames but, IIRC, as a filter is irrelevant for darks/bias as the telescope should be capped, you should select the dark filter via the INDI filter wheel tab prior to taking darks/bias as Ekos does not seem to change filters. That's what I do.

Maybe there should be an option in Ekos to use a dark filter instead of, or in addition to capping the telescope. This would make taking darks more automated for those who do not have an automated cap such as the Alnitak or similar.

Thanks for the great tutorial.

I have started reading it and it will likely help a lot if one wants to add functionality to a driver, or develop a new driver either from scratch or from an existing one.
