So my kid getting into #rockhounding means that I'm starting to look at getting a rock #tumbler, and thinking I might #DIY with junk I've got around. But the search results that I'm finding with DDG are all either videos, very incomplete instructions, or clearly AI generated.

So if you've built one or just have one, what advice do you have? How fast should it rotate? Can I get away with a 36oz peanut butter jar for the drum? Can I really use sand instead of buying special grit?

My son, the CS major, helps me program my #linux based #raspberrypi pool controller. We use #nodered because it gives a really nice little dashboard and controls all the GPIOs well.

I was looking into the code and spotted this lovely little bit of type coercion. 😃 I can completely relate to what kind of mood he was in when he probably found some stupid bug because it was dealing with the letter "0" instead of the number 0.

A diagram of boxes and arrows. This is how node red programs. You have boxes that do stuff, and lines that represent messages passing from entity to entity. There are things like "pool pump timer" and "pool status". In the center is a node labeled "Convert to an integer god dammit"

The glider winglets have been sanded and buffed/polished...well enough.

I did not use the polishing machine. These are small parts and somewhat fragile, so I buffed by hand.

The winglets have electrical connections (spring loaded car door jamb connectors, lol!) and a molded receptacle for these nav/position/strobe lights:

The 2nd and 3rd photos show a progression from ugly runs and drips...to a scraped surface that is almost ready for sanding.

Glider winglets, buffed reasonably well. They are removeable and feature electrical connections for tip lights.
Ugly runs and drips on the paint stand tall in low-angle light.
Scraping the paint with a single edge razor can smooth the runs and drips so that they stand only a couple thousandths of an inch (0.05mm) tall. Then they are ready for sanding for final smoothing.

I did my first Mouser Electronics order in quite a while. I bought some special Pots to fix and restore my original, American made Mackie 1202. It's been a back-burner project for quite some time.

I also paid my first Tariff that I'm aware of. They had a line-item for it. It wasn't a huge order and the estimated Tariff was about $2.50, but still...

FUCK THE CHEETOH.

The average Apple iphone is supported for 7 years, & a minimum of 5 years after the product is discontinued, which is better than androids. Imagine if your car was not supported after 7 years. I manage to keep a 2012 airbook useful, nothing wrong with the hardware, but in the software world its days are numbered. I also manage to keep a 2003 car running.

I've been looking into tinkering with old game boys and stuff and found this: kickstarter.com/projects/jamet

Amazing, a raspberry pi zero in a GBC shell 😍

It's reportedly in fulfillment phase, and a couple days ago I read on its website (reboi.io) that additional preorders are available outside of the finished kickstarter campaign. There was no preorder link on the website then.

Today, reboi.io is giving 403.
Does anyone know what's up?

Defencestration.

Most of the fence posts pulled out easily, with a few exceptions. The fence itself however was ingrown like a bad toenail. I had to pull really hard and then clear a bunch of soil, roots and weeds off the bottom.

A young maple (those really like to self-seed around here) and some thorny monstrosity that had incorporated several fence links got extracted, too.

Now there's room to expand the garden with some no-dig beds :)

A garden on the left, a former goat grazing area on the right, separated by a chainlink fence that is now laying down and partially rolled up. A lot of soil has been torn out where the fence was deeply embedded in it. If you look closely, you can see another overgrown concrete beam that was missed at the last harvest. Also one of the many pieces of galvalum sheetmetal laying around everywhere.
A pile of former fence posts laying on the ground. Most are galvanized steel pipes, a few rusty ones, a large steel beam with concrete footing and some weird profiles made of weird material with weird gunk stuck in them that I have no idea what they once were, but they're lousy fence posts. Behind a few tractor cab windows that were leaning on the fence, a bucket to collect various trash found in the process and an upside down beer crate with reclaimed ceramic tiles.
