I bought a cheap mini-PC board at a street market. The seller said, without confidence, that he was told it’s an “Intel Nano”. But he had a stack of different boards so it’s dodgy info for sure. When I do an image search for “Intel Nano”, nothing quite matches.

I would normally run it and probe for the hardware, but I don’t know how to power it. It looks like there are two pins in a green box that probably need DC power.. likely 12v but I would rather not guess.

Any help identifying this thing would be appreciated!

The “1820” possibly corresponds to “G1820 Celeron”, but that’s a far cry from identifying the model of mini PC.

Normally tubes do not give a pressure spec, just a size. Tires always give a max pressure figure. Exceptionally, I bought a universal innertube for a range of sizes: 26—27.5″ (only because it was quite cheap). The box for the tube has a chart listing all the sizes and widths it can support, and a pressure for each size. for 26×1.75″, it gives a pressure of 3—3.5 bar. My tire gives a pressure of 4.5 bar. The chart on the innertube box indicates 4.5 bar only for the largest smallest size (26×1.50). As the air volume increases, the pressure is lower.

e.g.

|--------+-----------+---------|
| 40-559 | 26×1.50   | 3.5—4.5 |
| 47-559 | 26×1.75   | 3—3.5   | ←
| 50-559 | 26×1.90   | 3—3.5   |
|      … | …         | …       |
| 57-584 | 27.5×2.25 | 2.5—3   |
|--------+-----------+---------|

So this is annoyingly confusing. I pumped to 3.5 bar because I’m afraid to exceed the limit spec’d for the tube. Is that the right move?

I have a collection of innertubes that can no longer be repaired because either the valve broke or the break was on the seam of the valve. The old tubes give a lifetime supply of rubber bands cut to your width of choice. The whole tube also functions as a bungee cord.

But I have to wonder, can they serve us better by preventing future punctures? Two things to consider:

• A tube could be sliced lengthwise (not cross-sectionally), and it could give an extra lining between the tire and the inflated tube. As tires develop cracks that expose the tube, an old sacrifical tube could perhaps mitigate a puncture. Might it make sense to glue the old tube to the inside of the tire?
• Tubes are wasted when they break near the valve seam. What if a section of old tube is cut and a hole is made so that it can wrap around the valve of the new tube? Would it help reinforce the area around the valve? Might it be practical to do this to repair one tube with another where the valve seam is broken? I just wonder if the glue (vulcanizing?) would have a significantly negative effect on the elasticity of the area near the value. OTOH, perhaps that’s just what is needed.

Posted this. Got censored. Rightfully so, or trigger happy mod?

In !askelectonics@discuss.tchncs.de, I posted the thread “What did I buy? Need help identifying mystery board.” The mod censored it instantly. It was removed so fast I thought it never posted in the first place. I thought a broken network connection caused a dropped message and data loss. Luckily I could use the browsers back button to reach it.

Then it became clear: the Alexandrite client is not working for the user. It’s working for the mods by disappearing the user’s own work when the mods nix it from the timeline. It’s obviously a disservice to the user to be subjected to data loss. The data loss is chaotic and arbitrary. These are the original posts:

• https://discuss.tchncs.de/post/69059793 ← gone
• https://a.lemmy.dbzer0.com/lemmy.dbzer0.com/post/76800419 ← still there

Notice the discuss.tchncs.de copy is completely destroyed, not merely removed from the timeline. Incidentally, I got lucky by posting on a host other than that of my account. So there is still a cached copy on dbzer0.com. But despite the persisting copy, Alexandrite neglects to give the link to its own user. Had I closed the browser before noticing the removal, it would effectively be data loss because there would be no way to notice and no way to obtain the link.

There is a recent trend where it has become acceptable for apps to not work in the interest of the user who executes the app. This misplacement of duty by inverting who is being served is mostly an erosion manifesting from web apps, not user-installed apps (though Firefox is an exception whereby Mozilla often takes decisions in the interest of webmasters). Regardless of whether a removal from a timeline is justified, it’s not okay to subject users to data loss and deny them transparency.

The interesting take-away for users is to avoid posting on the same host as your account. If a community is local, use an external account to post there to avoid data loss.

I have a couple DAB radios with a dial that spins mechanically. The dials spin in steps, not smooth like a variable resistor. They also have a push-button so if you push the button it serves as an /ENTER/ button. What is that kind of knob called? I am struggling to even search for my problem because I don’t know the terminology.

I previously posted about how Beko kill-switched two of my washing machines to block me from using them -- to force me to throw them away. I happened to be on a site of an e-waste manager or something, and found this astonishing claim that Beko/Arçelik is:

“working together to build a sustainable cirular solution for the washing machines manufacturing industry”

If they want a sustainable circular economy, why not just publish their kill switch reset codes?

I used a 10mm masonry bit to drill for a 10mm plastic anchor like that pictured. The anchor spins freely in the hole, which I think is expected. I thought I read somewhere that the screw size should be 2mm less than the anchor. Thus 8mm for a 10mm ø anchor. But an 8mm screw is fat enough to rub sides of the anchor as it is inserted because I suppose the anchor is only 1mm thick at the opening. The guy at the shop confirmed that 8mm is too big. He said a 6mm screw matches and sold me those. After installing and loading, the anchor started to pull out.

Do I need a 7mm ø screw? Odd sizes get decreasingly common above 5mm. Yet 10mm sleeves are very common.. so it’s not adding up.

I would like to have a reliable PDF chart of bore,anchor, and screw sizes -- in metric. It seems there are plenty of such charts for Imperial/English units, like these:

• http://nfaspace.com/services/Forms_files/Anchor%20Classification%20Guide.pdf
• https://anchors.dewalt.com/anchors/_documents/uploads/DWANF_ICDWANCHSG_r01.pdf?1659150839

I’m not sure what a “#10” screw or anchor is (sometimes also written as “№10”). Does that refer to the metric size despite being in an imperial system?

(update)
The brick is rendered over with ~10mm plaster. The anchor is flush with the wall so about 10mm of the anchor is wasted. I think the anchor needs to be pushed in to be flush with the brick. But that’s a struggle. I think the proper approach is to screw in the screw just a couple rotations and then to hammer on the screw. But the anchor is either too big for the hole or something. The screw drives in but the anchor does not go with it. I think I will try softening the anchor with a heat gun and then try to push it in deeper. Or maybe I need a fatter screw just to drive the anchor in more.

The problem is worsened by the fact that as I screw, the anchor is coming out by about 5mm. So it’s even shallower than when I start screwing.

(update 2)
Now I see why I cannot get the anchor to be flush with the brick: I only drilled the hole deep enough for the anchor to be flush with the plaster layer.

So one theory is that I need to drill 10mm deeper so the anchor can be flush with the brick not the (useless) plaster. OTOH, the collar of the ancher seems a bit useless anyway for about 10mm.
