    Most of the projections are not geometry-critical so I think it’s just about projector placement and adjustment.

    What’s more interesting: what projector is it and how is it powered? It’s crazy bright for a portable setup.

    Also, did you write this?

      Powering it is the hard part. I use a lithium battery in constant danger of melting.

      Yes, I did write that. More to the point, I wrote a solarpunk mystery novel, which I’ll post about on Monday.

      Given the great response, I will post more relevant projections here. What community tag should I use?

        Still, what kind of projector?

        You could try going old school and using something like a slide, overhead or film projector for static images (with a modern mercury/LED lamp): you’ll get 3x higher light efficiency than colorwheel DLP (color filters lose ⅔ light each) and 2x higher than 3LCD (prisms divide light efficiently but polarization loses ½ of it).

            It’s how it works when you reply to a Lemmy comment from Mastodon. It will automatically tag the comment you are replying to and it’s parent.
