Mireia created a new topic ' Voice assistant?' in the forum. 3 months ago

I am lately reading a bit about voice assistants and found mycroft around and inmediately thought it could be a nice thing to have one (or several) of these voice assistant systems hooked to INDI. Imagine something like...

Hey mycroft, begin 2 star alignment
Alexa, move eqmod to Andromeda Galaxy
Ok google, take a 30 seconds ISO 5000 exposure.
Hey mycroft, start brewing coffee.

For some actions, if you use it with a RPI or stellarmate + usb mic / mini speakers it could even remove partially the need of a phone/tablet/computer. And it is cool anyways :)

I'm right now traveling and have no way to test it because I don't have the RPI 4 with me. I will check it in a few weeks.

Thank you, I will have a look.

In the meanwhile, gdb prints these last lines

Maybe it is something specific of the RPI Pi4?

I recompiled making sure that there were no missing packages (not even the optional) during compilation, but the segmentation still pops up as soon as the Ekos window is created.

Hi,

I just finished compiling indi and kstars in Raspbian Buster. Kstars works fine until I start Ekos, which triggers a segfault. Has anyone experienced the same? This is the log I get in the terminal...

Mireia replied to the topic 'Preemptive corrections on tracking speed based on astrometric solution' in the forum. 5 months ago

Or even, more refined and cool, if we know how the stars trail, estimate the polar alignment error and just adjust the tracking speed in both axes to compensate it, so only the field rotation remains. For short focal lengths I think it will remove the need for a super accurate polar alignment or guiding

Totally. I still need the new guider to arrive, until then I'm basically stuck with underexposed 180s ISO2500 subs.

But the mini should work too no? It is what they sell by default with asi air.

Well, the mount has very mixed reviews in Cloudynights. But don't get me wrong, I think the mount even for astrophotography has an outstanding design and I wouldn't hesitate to buy it again (although I would have chosen the package with the mak127 to also do some visual ;). If you get a decent unit is like having a Star Adventurer on steroids for almost the same price and the same weight/volume. Of course, if it would have targetted the astrophotography community there would be things to improve a bit, like more consistency in the backlash and some little details like a better clamp. But its price would have skyrocketed for sure. And anyway, my unit is pretty good, the backlash is not very noticeable visually and the gotos leave me the objects pretty well centered.

I would really love to see how hackable it is in the long run, how tunable it is to reduce the backlash in those units that need it (or even how possible it would be to convert it to a belt driven system) and what other crazy ideas people come up with.
