Hey friends, does anyone know what either of these objects are?
(They were found in a deceased relative's jewelry box.)
Please boost for added eyes, thanks! 😊

The lettering on the object on the left says:
Hadley Made in USA
Both ends open up to 90⁰ and the main body expands and contracts about a centimetre.

A clever person has said that the object in the right is a Writescope telescoping mechanical pencil. Thanks!

I'm failing trying mitxela's trick of wrapping a wire around an ironbit for SMD soldering, any one got any ideas? This is a traditional 25W Antex iron it's wrapped on, but it's not getting hot enough on the wire, it boils off flux, melts low-melting point paste but doesn't do anything to existing components:

@penguin42
The wire is a bit thin, do you happen to have a ~1.5mm copper wire?

This is the ideal truck body. You may not like it but this is what peak performance looks like.

Those who write such pearls will not even understand what is wrong here.
These are the same ones who draw pictures of Trump against the backdrop of devastation - they do not realize that the shit they are in is the result of 4 years of rule by a completely different party😉

BUT IT WAS FUN!

There was once such a simple program as Dia. But it didn’t know how to rotate an already installed primitive, which infuriated me a little🤣

A fully soldered board, three dozen wires later, worked from the first launch.
Not very surprising - I’m usually precise and methodical :) But I won’t show the other side, it’s very difficult to neatly solder all these wires.

What's next? firmware? No!
Next I will design and print the enclosure for this thing. Well, because I haven’t printed in a while and because the last thing I want is to touch and damage one of this pile of wires🙃

yrabbit,
@yrabbit@mastodon.sdf.org avatar

Enclosure will be simple, but I'll try something new: I've never used heat inserts before🙃
I just need to figure out what diameter the holes should be.

yrabbit,
@yrabbit@mastodon.sdf.org avatar

@aeberbach
Yes, you're right, it's an M3. Thanks, I'll try to design holes like this👍

yrabbit,
@yrabbit@mastodon.sdf.org avatar

@aeberbach
It turned out well!
Yes, I understand that usually these inserts are made on the other side, but I don’t really trust them yet, and in this way the mechanical strength increases many times over.

I'll have to sort out this drawing around the edges - apparently Linear Advance is playing pranks.

@aeberbach
The upper half of the player enclosure.
A disgrace, although readable.
I can't smudge the PLA well on the first layer (let's say a line width of 0.6) because then the letters become unreadable.
It's probably worth doing such things on the last layer.
Or change the nozzle to a smaller diameter.

The top half of the box with inscriptions. Lots of shortcomings.

Can you drive a stick shift (manual transmission)? 🚗

Answer yes even if you haven't driven one in a while.

Please boost and reply with where you are from

@dancinyogi

Two rules:
0. The gear changes when the clutch pedal is pressed.

  1. The clutch and gas pedals work like a swing: one is pressed and the other is released.

Keeping this in mind, you will be able to drive with some success. Mastery, as always, will come with repetition.

!!!And I’m saying this, who won’t even come close to the car. But in life anything can happen and you need to know very simple rules that will allow you to drive (badly, but drive) in an emergency situation!!!🤣

This thing burned out after being unable to withstand a couple of CDROM activations - and it’s not like it was working with a laser and so on - I haven’t learned how to give such commands yet.
So now a 600W computer power supply is used.
Just a note - these little power supplies are a joke.

I don't mean Meanwell and Co - but it's hard to find a 5/12 combo model there

You probably haven’t come across Apple USB-C chargers: they’re full of all sorts of beasts - 14.5V, 5.2V etc

We need a breakthrough, so make yourself useful - rewrite all Fortran libraries in ! 🤟

"...bashing their huge matricies to bits without Fortran."

This reminded me of the old saying about science: new theories win not because they are true, but because the defenders of the old ones die 🤣
Perhaps those who write AI are young and simply do not know what Fortran can do. (not that I know, btw)

Hollywood vs. Reality: space station edition

A photo of the interior of a real space station: cramped and cluttered, wires and tubes running on every surface (walls, ceiling, and floor), zero windows, circular hatch leading to the next module because real space stations are fitted out more like U-boats than five star hotels

@cstross Are those fluorescent lights at the top? And two of which have already died?
I thought LED things are used in space - you know, saving energy, weight, lack of a glass balloon, which, if damaged, turns into a bunch of deadly glass fragments, etc.

Emotions? None - it has long been said that there are no silver bullets (by the way, I need to re-read The Mythical Man-Month at my leisure). But it will be funny to watch how a crowd of celestials will swarm into the comments and start saying that you can’t write like that in Rust, that it’s correct to do this and that.🤣

It's true. And besides, there were about 50 of them riveted together so far.
Let's look at the situation in December.😉

:raspberrypi: Raspberry Pi 5 is coming :raspberrypi:

With more than twice the speed of Raspberry Pi 4, and featuring our brand new RP1 chip, we’ve refined the Raspberry Pi experience.

It’s the everything computer. Optimised.

Priced at $60 for the 4GB variant, and $80 for its 8GB sibling, units are already available to pre-order from many of our Approved Resellers, and will ship at the end of October.

Announce the list of licenses that need to be purchased. Do one still need to pay for MPEG-2?

Well, yes, a simple trick from the seller - in the catalog there will be a picture of the board at the price of sdcard😀
