wow.
I'm not sure how I feel about that.

I love EVERYTHING about this! Random just because projects are the best. In particular I love the line where he hopes it's reassuring to students that there are real life applications of y=mx+c! Right after 5 minutes of rotational matrices.... Which because I do not design control systems is the first actual application I've seen of those in over 20 years. Kiiiind of considering giving this a try.... Not that I need any more projects.

I'm surprised that he built a project involving lighting up a plane through a cone-shaped tree and didn't mention conic sections. Missed opportunity, really.

Speaking of missed opportunities:

I'm surprised that he built a project involving lighting up a plane through a cone-shaped tree and didn't mention conic sections. Missed opportunity, really.

It was a bit elliptic, so you might have missed it -- but, between the hyperbole and the circular references, he did offer a parable about a cone and a plane.

Greatest respect for the DIY spirit and the teaching orientation of the video, which I admittedly skimmed while watching It's a Wonderful Life...

For a little less than $200 you can get smart Christmas lights that have pretty darned sophisticated 3d mapping capabilities. Dare I say there's an app for that?

This is fantastic, thank you!

The LED strips with the clock line (as used in this project) are much more expensive but the ones without are notoriously hard to drive from a Raspberry Pi. Fadecandy has a solution for that.

This was fascinating. I really enjoyed listening to how he did this.

I looked into it a bit and learned that accessing the camera from Python on MacOS has recently become difficult (or maybe impossible?) because of fairly recent (and probably well-advised) security changes. So replicating this exercise on recently-updated Macs might not be trivial.

But I’d love to be wrong because I’ve been thinking of a very similar project and would appreciate any tips to get around the new security measures!
