Polar Aligment (mander.xyz)
submitted 1 year ago* (last edited 1 year ago) by xurxia@mander.xyz to c/astrophotography@lemmy.world

I'm thinking about an IoT Polar Aligner. The main idea is to use a Raspberry Pi W with the camera module to find and detect the North Star and display it on the mobile phone. The final goal is to connect it with servos so that it can automatically align itself. Does anyone know of a similar open source project?

I have used CircuitPython in some projects, especially with my children. Python was easier for them than C. For small projects (domestic sensor, remote control car,...) there is no difference in performance. For those use cases that are more demanding and squeeze the possibilities of the SoC to the maximum, obviously, it is not worth it. Taking this into account, I think it is an alternative for many DIY projects that are being done out there

As always with these news it is still too early to draw conclusions: more analysis and tests are necessary.

I agree. It is more a curiosity thing than a real life project. But it helps to show the potential of this SoCs and it is a good practice for a lot of things.

I found this tutorial about how to use a raspberry pi to add a digital panel to old cars (canbus port needed)

Yes, you can. Python has Email package to manage email through STMP protocol. I use it daily in my scripts. Attached link is a tutorial of Real Python:

Yes, the idea is use in the future Output.status as a way to route to different pages depending of the model result. For example, when /list endpoint is called I could return 1 to show the feed list, and 2 to render a page with a message and suggestions when the feed list is empty. The same with negative numbers but for errors.

I have developed a project in #python to follow #RSS feeds and send an email with daily news. It is more an excuse to practice python, git and design patterns than a real project, but feel free to use it if you find it useful. Suggestions, opinions and feedback are welcome.

Thanks! I will try it. I was an user of this sw but recently I have moved to Pyto as it has more libraries (OpenCV, etc), pip support and a newer Python version. Pythonista has its pros too.

[-] xurxia@mander.xyz 4 points 2 years ago

I find it very interesting and I want to do one with my kids. The guide is good from a step by step point of view about how to make one, but I think a couple of examples about what kind of data can someone get with it and what can someone expect to "view" could be very helpfull too

I have just created a new community in Lemmy about Generative AI like GPT or Midjourney. The subjects are diverse: from news to development

After preview it will be a paid subscription additional to Office365, the same strategy as Office Copilot. I hate this policy of pay for a product then still paid for more functionalities... at the end of the year you will have paid a lot.

Microsoft says Python in Excel will be included in a Microsoft 365 subscription during the preview, but “some functionality will be restricted without a paid license” after the preview ends.

I fully agree with the post. Except for a fast prototyping or a short personal script where it could be not necessary, type hint is a must. The subject is not only to guarantee that the program now runs without errors, but it will be still working right in the future too, even after a developer (either the original or other) make changes to the code.

Since the last update, half of the times I open the app I see All posts but in my preferences I have set Subscribed. The rest of the times it woks fine.

I want to thanks one more time to the developers who are making this great app 👏🏻👏🏻👏🏻 I really love it!

Hi,

I have used goto instruction a lot when I started to program in Basic ( an Amstrad CPC 🥹). In this context goto had logic. But in modern languages like python I think it is a very bad idea:

  • Understand the logic is more complex
  • Functions and methods are a better and more powerfull alternative
  • It is dangerous: add or remove a new line of code could have bad consequences

Regards

The most probably! Thanks a lot!

I have just installed the last version and it comes with some errors:

  • I can't set NEW as default option for sort posts in config
  • I can't see communities wich I am subscripted
  • When I search the communities section is always empty

You can use global variables, it is true, but I prefer singleton because I have all config variables and logic encapsulated in a class. The first time the singleton object is created it reads all the config variables from a file, and with its methods get and set manages them. The Config class doesn't know the parameters names of the config file neither the number, it dynamically reads the file and creates the attributes, so It is a very reusable code that when you program using OOP is a more natural way than implementing like a module.

Related to this, I group config variables by sections so it is more clearly for me, then the singleton object dynamically creates an array for each section, and a variable into the array for every variable in this section of the config file. Access to the config info is as easy like this:

   conf = Config()
   conf.get('DB', 'server')
   conf.get('DB', 'login')
   conf.get('DB', 'password')

I use a singleton class called Config (some times I use it as a Cache too)
