I'm always happy to see one of my videos on HN! I'm really glad to be getting back into the habit of making new videos. Let me know if you have any questions or suggestions. See you at Open Sauce!

I may have the opportunity to use a much higher framerate camera in the future. Please leave suggestions for things that are fairly transparent to x-rays (no metal, or very thin small internal parts), and demonstrates the utility of high speed capture (typically things breaking, bouncing, shattering). The last requirement is that the object be very small, just 1 to 2 cm long. Since learning about ptycography, I may try that as well since x-ray ptycography is one of the real world uses for these sensors.

In Win11 as admin, take ownership of the following files, and remove all permissions for the system user. This prevents any updates and can be easily undone at any time. I turned off updates, and life is much better. I no longer feel guilty about having my system "at risk". It's no longer worth the pain of updates.

WSJ reported that many folks received "routine flood warnings" hours before the disaster but may have ignored them because they were... routine. I think "alert fatigue" is a real problem, and today WSJ highlighted this report which has some data on who opted out of wireless alerts, appartently five times more likely to opt out in Texas compared to Vermont.

I measured the pure iron powder as well. It shows no measurable area inside the BH curve, which at first seems incorrect since the textbook retentivity value for pure iron is fairly high. The textbook may be referring to a single iron magnetic domain. In a practical sample (even a solid piece of iron, let alone powder in epoxy), there are likely many magnetic domains that cancel each other out, and "soft iron" is used commercially for the very reason that is has extremely low retentivity in bulk.

You should definitely contact Kron Tech (makers of the system -- let me know if you want an introduction). I have some interesting image processing videos coming up -- nothing to do with color reconstruction, but that also sounds good. My project pipeline is pretty full, but I will let you know when I am adding new ideas.

I am a Patreon creator that is very happy per-creation billing will remain an option.
