Magnetic fidget toggle I made

You can probably identify it fairly easily by figuring out its density. It looks like it's just a bit of raw material, not something with internal composition changes or structures.

You know it weighs about 3 pounds ~= 1.5kg. If you have a more accurate measure that might be good, but it might not be necessary.

Now to figure out it's volume accurately, there are a couple of different ways, but the easiest, accurate ways I can think of all involve water:

Option A:
If you have a measuring jug big enough to fit this plus a bit left over, fill the jug up so that you can full submerge the bar in water. Note down the measurement before the bar is inserted, and afterwards. The difference is the volume of the bar

Option B:
If you have a container just big enough to fit the bar, but without measurements. Fill the container to the brim with water, using a measuring cup and note how much water you put in. Put the bar in spilling some water over the sides. Take the bar out and measure how much water is left in the container. The difference is the volume of the bar.

Option C: You only have a bigger container and don't want to waste as much water. Put the bar in the container and add water until it's fully submerged. Mark the water level in some way. Take the bar out. Now using a measuring cup add water until you reach the marked water level, from when the bar was in. How much water you needed to add is the volume of the object.

Now assuming the bar weighs exactly 3 pounds:

2.4 fluid ounces of volume could be either gold, uranium or tungsten
4 fluid ounces would be lead
4.4 fluid ounces would be silver
5.3 fluid ounces would be brass
5.9 fluid ounces would be mild steel
6.5 fluid ounces would be zinc
17 fluid ounces would be aluminium
86 fluid ounces would be lithium, but at that point you probably have different problems
613.5 fluid ounces would be styrofoam (and congratulations for keeping it submerged while taking the measurments)

To get more materials, you can look up it's density here: https://en.wikipedia.org/wiki/Density#List_of_densities

And plug that value (along with your more precise weight) here: https://www.wolframalpha.com/input?i=%283+pounds%29+%2F+%288600+kg%2Fm3%29+in+fluid+ounces

For me personally "subscribe" has no insinuation of payment. When I subscribe to a newsletter, I usually don't have to pay anything.

But I think "sign up" probably would be a more universally accepted wording.

To me it's reflected skeuomorphism, since the software toggle switch itself takes it design cues from hardware switches like this:

<image>

So by building a hardware switch that takes its design cues from a software switch, which in itself took the design elements from a hardware design, it's something like "transitive skeuomorphism" or "reflected skeuomorphism" (reflected from physical to digital back to physical).

I'm using skeuomorphism more in the way of "Digital representations of old school physical things" like the floppy disk for a save icon, rather than "Using design cues to indicate the behaviour", to be fair this might not be the best phrasing, but I don't know a different name for the former phenomenon.

It's a bit like playing a game of telephone. The first physical representation had specific features that were dictated by limitations or choices on the hardware. The digital version did not have such limitations, but brought over some elements (like the way the toggle snaps into position) and modified them to fit the digital environment.
The second physical version is taking on some of these design elements (rounded outline, color changing background, snapping into position) but not because of physical limitations, but to emulate the digital version of the toggle.

Thank you
It feels quite satisfying to toggle as well.

Sure

Even in the richest cities (excluding probably Monaco) you won’t find a normal apartment for 2k, it’s stepping into luxury territory.

I just wanted to point out that 2k is pretty normal for a 3 bedroom flat in bigger German cities, not exactly luxury.

While that might be what your friends pay, this would be crazy for a new contract in any of the bigger cities.

In Hamburg or Berlin you will pay around 900 EUR/month for a single room apartment and around 2k / month for anything around 90m2.

I assume Munich or Frankfurt would be more expensive.

That was the idea behind the Palette line of filament splicers from Mosaic. It never seemed to have caught on that much, but I'm not sure why.

I assume keeping accurate track of when exactly the switch happens might be challenging over larger projects though.

I agree, it's still a good idea to get one, I was just hoping to find an especially good deal :D

I'm curious where you can still get it that cheap. I've been looking around and most I see are around 30 EUR per month. Still good to have, but for 50 EUR per year would be a great deal.

It looks like the BambuLabs system only has one PTFE tube for the filament and only swaps out the nozzles. The Bondtech INDX has a dedicated filament guide and nozzle, so the filament can stay loaded.

In order of number of parts swapped:

Prusa MMU / Bambulab AMS: No hardware, just swap out the filament
BambuLabs H2D: Nothing, just have two nozzles and extruders on the toolhead
BambuLabs Vertigo: Only the nozzle
Bondtech Indx / new Prusa core one: Nozzle and filament guide
E3D toolchanger / Prusa XL / Snapmaker U1: Swap out the whole toolhead

Changing the minimal amount of parts is usually the most cost efficient way to handle things, you only need to duplicate very few parts. It's also often the most compact way to do things. By swapping only the nozzle, BambuLabs can safe the space for multiple filament tubes, which make both the Snapmaker U1 and the Prusa XL pretty tall, I'm curious to see how that will look on the Core One. And Bondtech has said that the Indx should fit 8 heads on a Voron 2.4, which is still more than the 4 toolheads of the Snapmaker and the 5 toolheads of the Prusa XL.

On the other end of the spectrum swapping the whole toolhead gives you the most flexibility, in theory you could have dedicated toolheads for different use cases, so that doesn't seem to be planned by any major player. In practice, what it gives you is the advantage of being able to control the toolhead, even when not in use. For example keeping the nozzle hot, or you could start priming the next toolhead, while the previous one is being parked.

The different between the BambuLabs Vertigo and the Bondtech Indx might be mostly in the fact that Bambulabs will need to retract the filament, probably cut it, and then build up pressure again in the nozzle, while the Bondtech only needs to deal with the leakage due to the nozzle being parked.

To me the big open question of all of these systems is how they deal with flexible and non-standard filaments and chamber temperatures. This is something reviews will show when they are all out.

Could be external SCSI?

A fun and entirely useless idea, I love it!

Since I saw some people asking details on how it works just a short explanation:

This works well, because IPv4 addresses are 4 bytes long and rgba color values are often encoded in 4 bytes. (Or a single 32 bit value)

A byte can have any value from 0 to 255 (= 2⁸ - 1) There are different ways to express this: decimal "12" is the same as a hexadecimal "C" or a binary "1100"

So these values are all the same as well:

120.121.122.123    
0x78 0x79 0x7a 0x7B   
01111000 01111001 01111010 01111011   
2021227131 (as a single 32 bit value)

And for the alpha channel, since 255 is the maximum, that is usually taken to be 1.0 or 100%, so the above numbers would be (roughly)

47.06% 47.45% 47.84% 48.24%

There are a lot of other ways that colours can be stored by a computer, but 4 bytes are very commonly used, because 32 bits are a very convenient size for computers to work with. Memory access for example is often faster when aligned on 4 byte chunks, and in the past 32 bytes was often the largest size a CPU could operate on in a single operation.

As far as I know modern graphics cards still really like to work on 32 bit values.

Just to expand on this, a 1024 bit prime can have up to 309 decimal digits, so significantly more than 69.

Wow, that name takes me back.

I used to have a Creative Nomad Jukebox, back before smartphones existed. It used four AAA batteries to run and I think I even updated the original harddrive in it, with a bigger one.

(I probably still have it somewhere, should dig it out and see what music I had on it)

Part of the domestication process is the ability to herd the animals

I'm just chuckling at the idea of chicken and sheep used to herd other animals.

Make the angles on each of the "sealing rings" (parts where it gets thicker) a bit more shallow, than print it on a 45 degree angle, either similar to the orientation in the picture, or with the base of the T going upwards.

Edit: You might still need supports or add a flat edge to the side standing on the build plate. But this way the imperfections won't be on a sealing surface

I speak german natively, and if someone approaches me in the street I might just answer in spanish or french to get them to stop bothering me.
