2025-09-12 (F) Weekly Summary

I received some new boost regulators and tested one, but the power system failed. While I contemplated the next step, I left the battery installed, and I worried that I had depleted it, so I swapped it with a fresh one, and the system worked. The battery was probably the issue all along. I finally had a self-contained tagger.

I revised my screen footprint by drafting it in 2D, confirming the dimensions with a paper copy, then drafting with the confirmed dimensions. The model was large enough to have some wiggle room on all sides and still fit the header pins. Since most of the space will be unused, I added square windows for the infrared sensors through the sides.

I corrected my print settings and immediately improved the quality. I reduced the slopFactor variable to nearly zero, and my prints stopped lifting off the platform as severely. I printed a screen base for a NERF rail and a Weaver rail, then attached them to a couple of foam-dart guns.

I created some rail adapters attached to chassis pipes using a curved face and fastened with countersunk 1/4" bolts. I printed a handful of necessary parts, including a lens cap and backplane, but since I did not have any more printer slop issues, I needed to secure the nuts, so I dripped uncured resin on them and cured it on the spot with a UV laser.

I decided to convert two toy guns at once to save time, and they will each have different shapes and issues. The second one used plastic Weaver-compatible rails, similar to those found on an Airsoft gun. I printed a focusing array, but it had no parts that stuck out, so it could fit into the barrel end.

We talked about the first Enola Holmes movie, and we all enjoyed it, with only a few minor exceptions. Although some of the messaging was clunky, we will gladly feature this franchise again, given how fun and easy to watch it was.
