    Who would have thought that the perfect Christmas gift for you would have been a really good can opener?! (At least you didn't try to be too patriotic and use the one on a Swiss Army Knife.) A fun idea, and one I would never have thought of. And congratulations on not swearing at all those frustrating moments. Thanks for all the fun and instructive videos this year.

    That's pretty cool! It's showing not only the sun track and the clouds, but also the horizon profile as viewed from the deck rail! More detail than I would've expected! My house doesn't have near the view that yours does but I might try one on the roof as a set and forget project. (hopefully, I remember to set it next solstice and then remember to collect it next year...)
    Have a Merry Christmas and A Happy New Year!

      To be fair nothing would happen if you leave it longer than 6 months 😁 merry Christmas!

    All considered a good result, think I'll give it a try too. top tip, get a 3D filament cutter, quite handy to have for all sorts of cutting jobs.

      I never even heard of that thing existing I just cut PLA with the little clip that was included with my printer

    Thanks for sharing your results. Definitely worth another go.

    We have previously made a solar camera ourselves. As film we used a piece of printer paper with a red rectangle printed on it with an inkjet printer. You could clearly see that the red color had faded where the sun had hit the paper, but it is not as obvious as in your "pictures". Remember to close the can watertight so that the paper does not absorb too much moisture. To make the hole we used a 1 mm drill. Merry Christmas.

      wow I didn't consider using regular paper, that's great! 1mm sounds like it would be way too large for a pinhole camera

      @@the_space_koala Maybe the hole in the can is too big if you use real photographic paper, but the experiment was done with the things that were in stock in the workshop/house on a Saturday afternoon. However, I have a feeling that the homemade "photo paper" might not be sensitive enough if the hole was made smaller. I got the idea from an old hobby magazine from 195x where they used black/white photo paper as a photographic medium with subsequent development and fixation to see the final result. Incidentally, there was nothing specific about the diameter of the hole, just that it should be small. Now the idea is passed on if anyone wants to try something homemade. 😊

    Super. Not sure what I was expecting to see. Seems obvious now after seeing the result. You could move the location of the pinhole instead of tilting ? Inverted image so put pinhole nearer the top ?
    I've use kitchen scissors to cut the top aluminium cans. I guess ring pull cans aren't made for can openers.

    • @the_space_koala
      @the_space_koala  21 годину тому

      Yes I think I will use a longer tube next time and potentially placing the pinhole nearer the top as you said!

    Not so sure about your interpretation the angle of the can, I am no expert, but its funny how the light doesn't tail off towards the summer. It seems to me there is quite a jump. Also there is a brighter band later in the year so it might be good to keep, or consult weather conditions for your area, especially when you do this again..

    You like the dark! You vampire you.
    What about having a go at an analemma next?
