All Sky Camera Revisited

Recommended Posts

That was it - now running Ubuntu Mate 18.04.2 😀  Thank you very much.  Now I have to hope all the rest of the firmware works.

Set up Ubuntu Mate fine including WiFi and so far so good but on trying to run the AstroPi3 script to install INDI etc. I got the "dpkg is currently locked ...)" error message.  Now I had this before and fixed it so now I'm off to scour my posts and blogs to see if I can find it.

Found it earlier in this thread.  The test for dpkg in use is not needed and is wrong anyway so I shut down the RPi and moved the SD card to my desktop for editing.  These screenshots show the script file location and the edited script - highlighted in green.  I just commented out the required lines (#).

Script finished.  Probably installed more than I need but easiest to let it just run 😁  A couple of questions to say y/n to but nothing critical AFAIK.  Most pretty obvious.

Next comes the testing.  Then I shall want to add my own controls for things like focussing, camera cooling and dew heater.

It works!  Logged on from Mint desktop and set indiserver to run the camera driver then ran KStars/Ekos, connected to the ASC and set up the camera for capturing and downloading image.  I shall be updating my Tutorial on setting up the RPi with INDI for astro imaging shortly.

Having changed the RPi from the last time I ran the ASC the system queried the connection so I followed the instructions for clearing the error as shown in this screenshot.

Finally, here's the first image from the new RPi 3B+

Now trying to install Astroberry DIY but have a problem.  Here's a screenshot of the Terminal display.  @RadekK I wonder if you can help, please.  This is on an RPi 3B+ with Ubuntu Mate 18.04.2

I ran

sudo apt-get install build-essential

and then followed the instruction in Radek's Astroberry DIY page and it all worked.

Tomorrow I'll replace some of the files with the ones I edited to suit my own hardware and maybe get it all working.

I'll just repeat here that the safe way to remotely shutdown the RPi is

sudo shutdown -h -P now

After that the only way to reconnect is to power down the RPi and power up again.

Now have my version of the Astroberry Board installed.  This provides control of camera cooling and dew heater plus a simple focussing system.

Here are my versions of the Astroberry Board source files :- rpi_brd.hrpi_brd.cpp

I replaced the original files in the astroberry-diy directory but found that just recompiling didn't use the new files so had to force it by deleting the build directory.  Then I recompiled using the following commands :-

cd astroberry-diy
mkdir build && cd build
cmake -DWITH_WIRINGPI=OFF -DCMAKE_INSTALL_PREFIX=/usr ..
make
sudo make install

This was followed by

indiserver -m 100 -vv indi_asi_ccd indi_rpibrd

to run the server.  Then to KStars/Ekos to Start INDI.

The reason for not having the focus controls on the main page is to avoid accidentally changing the focus after carefully setting it up.

Gina,

I surely hope you took some notes because I'm going to ask you a 'question or two' about this project in a few weeks...😁

No problem Chris.  In fact, I plan to write this up in a Blog when I've got it working.

Added the HAT and checked the camera cooling control which worked fine.  Seems to be a fault with the A4988 stepper driver as the focus motor got hot.  I'll replace it.

Replaced the A4988 but though the motor stays cool it doesn't work.  Seems the motor may be burnt out.  I'll check and replace with another if so.  I have plenty of them.  Very slowly getting there I guess!!!

Motor seems alright - or at least the windings show the right resistance.  More fault finding to do...

Hi @Gina have you managed to run it finally? I've been to Chile for Solar Eclipse recently so most of the time offline. I should be back next week so let me know if there's still any problem with the driver.

It's been on hold for a while - been concentrating on my widefield imaging rig.  I don't think there's any problem with the driver now.  Thank you.

Hope you got a good view of the eclipse.
