Astrohat - An open hardware RPi Hat for astronomy equipment #47629
First board assembled with almost all components (since we have 3 identical double channels, I just soldered one to test it).

Initial tests look good, RPi4 booted OK, i2c devices responding, and channels seem to be switchable. Now I need to write a bit of software to drive the controllable voltage channel and test it :)

Please disregard the fact that the board needs cleaning after the initial assembly ;) (I know.. IPA... but the ultrasonic cleaner is yet to arrive) More updates soon!

Testing of board version 1.0 is progressing well. I have identified a couple of issues and changes needed to make things easier for testing/debugging and enhance functionality (you can follow development in the repo). In the meantime I am re-evaluating some of the assumptions around the needed functionality (especially for the presence of RTC since we will be having a GPS so...) but would like the input on those from as many possible users as possible.

If you can spare 2 minutes, you could help me by going to this survey link:

>> forms.gle/2hAYnpcskWXV3MWS9
and answer to some quick (choice) questions.

Thanks a lot in advance for everyone's input!

Thank you all for replying on the survey!

Here are some quick results from it:



Based on this feedback and fixes from v1.0 I went ahead and released a v1.1 version of Astrohat.

Major changes:
- Removal of RTC since it is expensive to do it right and people should connect a GPS (or get time from Kstars) anyway
- Formal adherence to the RPi HAT specifications to make software development and user experience much easier (EEPROM FTW!)
- Various component fixes on issues identified from v1.0

here is a pic of what v1.1 looks like


As I write this reply, v1.1 PCBs are in production and will soon be in my lab to continue testing.

I’m late to this party, but I am quite interested in the progress. I’ve been mulling over RTC vs GPS on my Rock64. I already made an Arduino GPS gadget for my Celestron mount.

Hi Folks,
I hope this promising project is still growing ! I'm very impatient to see the final version.

Hello everyone!

This is a bit of an update on my side:

Version 1.1 arrived and got assembled. All worked as expected and I can safely say that I am not expecting any major revisions for the schematic and electrical connections. There might be slight updates for component placement since I identified some things that could be done better.
Perhaps most importantly for version 1.1 is the fact that the EEPROM on the HAT works like a charm, meaning that the RPi on boot can identify that there is a HAT with specific needs present and assign quickly the right parameters on all peripherals and GPIOs. I am genuinely impressed by the cleanliness of the EEPROM solution for the HAT since it makes development and usage from end users so much easier.

Due to COVID-19 and some personal family priorities I had little progress on the software development for the past 2 months and things will be slow for the next month too. Since the hardware development is verified though I am inclined to send a board or two around to any takers that can commit on contributing for the software side of things. (@knro Jasem I am looking at you ;)

Thanks for all your supportive messages and thanks for tagging along in this journey. Hopefully we will have something that all people can use soon!
