大巻き取り棒

Next weekend there will be a Zoom gathering for folks who bought the baby takadai, to share tips and show off their braids. I’ve only made three braids so far, because I got caught up in epicycles of projects on how to improve it, including of course the full tinkertoy-takadai project.

So I decided to just strip off the tape, glue it together firmly, and start braiding with the new koma I made two weeks ago. Then I found myself staring at an empty filament spool…

Okay, now I’ve got a firmly-glued frame with an extended take-up spool, so I can make braids an inch wider than before, and approximately 90 feet long!

(and, yes, I could have printed a more practical spool at the same time I made the stand, but this one will be a lot more amusing to show off on Saturday…)

Black Ducks Matter

I know, I know, why wasn’t this the first thing I made on the 3D printer? Because I didn’t stumble across the model until yesterday, of course.

I need to try it again at higher resolution, in a more appropriate filament color. Or else buy new mini paints; the old ones are all dried up now.

Minkowski means never having to say your CPU is too fast

After I finished printing the new filament-spool makitori-bō, I grabbed something simple to try, namely a strain-reducer for masks. It included OpenSCAD source for precise sizing, so I opened it up. And waited. A lot. As I watched, the 38-line file chewed up more and more of my CPU and memory without even displaying a cheap preview.

Because for no good reason I can see, he implemented the shape with minkowski(). I left it running for a few minutes, and the only change when I got back was that it had passed 2GB of in-use memory with nothing to show for it.

Dear Apple,

When you’re through figuring out why your new releasebeta OS is bricking customer laptops, could you maybe explain how the brand new Time Machine full backup I made on my NAS “does not support the required capabilities” for an incremental backup. I ask because after the last Catalina security update, my USB Time Machine backup drive won’t even mount successfully…
