Finishing off pinhole cameras

This morning I had two online critical thinking classes. Then after lunch I went to Wenona School to finish off building pinhole cameras with the students – which we began work on last Thursday. I cut out holes for the different sized lenses we had and got the girls to tape the lenses into place, and then add tracing paper as a screen for the projection. We ran out of tracing paper and had to use tissue paper for the last two which turned out to be not as good as it has more texture to it, making the image not as clear. I’m hoping they can replace it with tracing paper.

Here are photos of the resulting cameras:

The largest diameter lens is on the left, stepping down in size to the right. So the projected image should get darker from left to right. It’s a little bit obscured by the fact that boxes 1 and 4 have the tissue paper, which isn’t as translucent as the tracing paper. But overall the project worked really well!

The science head is going to try to get the boarding school girls to take photos of the moon over this weekend when we get a full moon, to use for the 3D stereo effect. Hopefully they can get that achieved properly.

I walked back home, and on the way I passed the shop that has 3D-printed D&D and gaming scenery. It’s always been closed when I’ve walked past before, but today it was open! And there was a guy inside painting scenery. So I popped in to have a look and chat to him. He was happy to have a chat and we talked for several minutes about miniature models and playing D&D. Turns out this guy is also running an Old School D&D game, using the Swords & Wizardry retroclone of the original 1974 D&D rules. So it was cool to swap some stories about our campaigns.

The weather was warm today, reaching 24°C, the warmest day since early May. On Monday the forecast is 27°C!

I got home and taught three more classes in the evening, and baked a sourdough loaf which I’d made earlier. Phew!
