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?

Erosion as a sculptor in c/photography@lemmy.ml
[–] xurxia@mander.xyz 2 points 2 months ago (1 children)

You're right. In fact, in the place there are many more eroded stones with shapes that recall strange and ancient beings (or parts of them). Although the pareidolia will have a lot of the blame 😅

Yes, it is the same kind if stone and the same “sculptor”

CircuitPython: Python for microcontrollers, simplified in c/python@programming.dev
[–] xurxia@mander.xyz 2 points 2 months ago

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

Tonight’s Moon in c/astrophotography@lemmy.world

You're right. It was taken a day before but it gave me an error when uploading the photo (it happens to me with some frequency in Lemmy lately) and it stayed in the pending queue

Perseverance rover find intriguing Mars rock (mander.xyz)
 

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

Digital Panel for your old car in c/raspberrypi@lemmy.ml
[–] xurxia@mander.xyz 7 points 3 months ago

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.

Communication between Raspberry Pis on different networks in c/python@programming.dev

There are free IoT cloud solutions to send and receive data and that work with MQTT protocol for this purpose.

Lunar Halo (mander.xyz)
 

It is a bad quality photo taken from a mobile. The circle that surrounds the moon is formed by the refraction of the moonlight when passing through ice crystals present in the atmosphere. At times surrounding the moon itself you can see a circular rainbow (they all are, but we see only half of the solar rainbow). This phenomenon is called a lunar halo.

Question - Tips for Polar aligment (mander.xyz)
 

Tonight, if the clouds allow me, I wanted to take pictures with my Skywatcher Star Adventurer mini. As I'm going to set up a small telescope (a Celestron C90) I need a very good alignment to the Polar so that I don't have any traces left. Tips to make an alignment as accurate as possible? Thank you

My first photo with a telescope. It is not a incredible shoot but I am very proud of it.

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.

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

BUG - Preferences are randomly ignored (mander.xyz)
 

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!
