Head shape matters. I only wear sports stuff for cycling and do not care what others think of that. My old Smith's saved an eye once. I only like to ride with frameless because roadie. The cheap Chinese NRC frameless are half decent. They have a full range photochromic version and their plasma metal sputtered coatings are good quality, but the lens shape is a basic flat. People think they are high end but mostly due to my other older riding gear that is very high end. Still, when casual I wear aviators.

This is how we all looked through a translation app from 2017

[–] j4k3@lemmy.world 1 points 2 hours ago

They are working to include Whales Dolphins and Elephants. Recent breakthroughs are on the verge of translation. I know google is mostly in that space but I think I recall meta was mentioned by Anton Petrov a couple days ago.

Put words to those looks. What do you think she was thinking?

eBay. Selling at 6 figure levels and they still have no support for sellers, treat you like crap, obfuscate what you're actually paying in all combined fees. Mine never got below 39% including all fees combined, shipping, tax, transaction, and platform with a perfect account. For the actual work they do, they are not worth half of that. If they were not a monopoly, a competitive market would be half from all involved. Taxing used goods is criminal. Logistics is a scam of ridiculous bureaucracy, and online transaction processing is more like a skimming operation with a government piracy charter, while actual eBay is mostly automated.

We don't need any more furryGPT, we already have diffusion at home.

All the best researchers went to Anthropic and elsewhere. The difference between proprietary and open weights is meh now. SolarRoofGPT burns the Sol, and tech bro digi slave traders. Long live open weights Chinese AI.

Looks legit all the way down to the goat. Screams tribal dogma

My goto brain game is how many digits of long division I can do just in my head. Usually only like 7-10 cause I'm dumb.

Get into writing your own fiction stuff you're really interested in. My science fiction universe is about the first stage of interstellar colonization. I love working out the technology and what the experience might be like without any fantasy magic involved. The best part is the positivity that comes with imagining a distant future and what is actually possible. It creates perspective about where we are actually at now and how limited it truly is.

I'm the blackest of black sheep but also the smart one so they are as conflicted as I am and unable to argue without getting wrecked...small victories

You mean the Epstein fulcrum that leveraged political support for a Palestinian genocide and forced the USA to bomb Iran because Epstein was mossad and collected leverage using pedophilic prostitution that Donald Trump regularly solicited?

It tries but the value is floating until it actually has a full charge cycle. There is no way to know what the entire voltage range is. You're getting into how efficient the chemistry is over time and that is impossible to measure. It can be estimated, but that is all theoretical and not real. When the battery is fully discharged, the time, temperature, and current can be used to determine Coulombs and that is the actual energy capacity.

I'm not an expert, but I have built many circuits. My main experience here is in reverse engineering some gaming hardware that had an advanced battery management chip from Diode Semiconductors. That had such a Coulomb battery meter. The board was a 3 layer PCB and I took that as a challenge. The batman chip was also a small ball grid array (pins are inaccessible on the back side. I didn't have xrays when I did the first trace of all pins, so I had to fully understand the chip to trace all connections only using the vias. I think I have a chip or two in parts drawers that do the same thing, but I never built anything with them, or at least haven't yet.

I just watched a Geology Hub upload on the Cerberean Caldera super eruption in what is now Australia. It happened over 300 million years ago, but in terms of the total age of the planet, even 300 million years is a relatively tiny blip. So have there been any significant epics to truly say events like x, y, or z will never happen again – in any statistically significant way? Will there be another Deccan or Siberian Traps or Columbia River Flood Basalts – one geologic timescale day in the future and countless more in the eons to follow?

I have heard the term news aggregator too. What do these definitions mean to you? How would you define the category?

 

This has been through many days of iterations and designs. Most involved over center mechanisms or wheel levers before this design dawned on me. The bottom right is how it prints. The "spring" is a double forked 10mm bridge in the last few millimeters inside the enclosed print. The visible "clamp" is connected to the spring by forking into two paths that branch beside the tube that the spade terminal is inserted through. The clamping force is not great but it is sufficient for a reliable basic electrical connection for bench testing. The pictured driver is a very small tweeter and is barely held in place with both wires inserted between the print and spade terminal.

I wanted something that would fit on the faceplate of the little hacked audio amp enclosure I have been designing. I think 6 of these will barely fit across the front and under the actual circuit board assembly.

This one might be worth the hassle of setting up an account and sharing on printables if it does not require the goggle server connection like it did in the past when I tried.

The thing is, I dial in my prints to 0.3mm clearances and this absolutely requires that clearance. I do not care to print other people's designs because most are really terrible for things like supports, designing for 3d printing, clearances, and general slop. I'll occasionally toss someone else's STEP or STL in FreeCAD and rebuild the thing but I usually just use some conceptual idea of anything I see elsewhere. I think with this one, I could share it as a negative Boolean STEP file to be most useful. Then it would only require others to import and do a boolean cut operation to use the design. Maybe I will do so if it works out well in my enclosure with 6 of these all resolving well and functional. What do you think, would you ever care to find and print something like this in one of your designs? Do you think anyone would even understand the value of printing such fundamental componentry instead of buying hardware and gluing it together with a 3d printed design? Like, this could easily be configured to use a loop of solid core copper wire as the connector terminal for a low voltage bench power supply that requires no other hardware.

Also, I had a rather irritating encounter with Dessalines (the Lemmy Dev) on ML a few days ago. I want to move off of Lemmy but I kinda like the rest of you, so maybe piefed is an option. I haven't looked into it deeply as I thought rust was worth supporting more, however empowering these guys as authoritarians is not on my list. I'm in a position to move this community if people want but like I always say, I'm just the janitor here. I do not matter. I would just as soon give this place to someone else if that is best for the community. I only want what is best for all, which is probably stability first and foremost, but if you feel otherwise, maybe mention it, maybe we'll make it happen.

 

Posted in good faith and got the extremely cowardly and totally incompetent response of a ban with no name attributed to the log and no message of any merit or value. Fuck that incompetent stupidity. I want nothing to do with this. No excuses.

Found out about this website from today's Geology Hub uploaded on YThttps://www.youtube.com/watch?v=v75f530yFOY

This crystal doubles images, meaning that if you look through it that anything on the other side whether that be text, a person, or a photo of a volcano will appear to be doubled. But, why does this unusual optical property occur when utilizing a crystal of calcite? The answer is a fascinating phenomenon known as birefringence, which this video will explain through the expertise and analysis of a geologist.

This is the about-page of which text continues past the posted image on the left side:

And as a further aside, the image was made with an F-Droid app that is new to me but popped up 3 months ago apparently and has a lot of great features for stitching images and creating content:

lassitude (lemmy.world)
 

Noun

lassitude

  • Lethargy or lack of energy; fatigue, langour, listlessness

(countable and uncountable, plural lassitudes)

example"There was a time when he was a rebellious and unpromoted captain of the First Foundation's commercial empire, when it would have been himself rather than Channis who would have taken prompt and daring action such as that. Was the Mule right? Was his controlled mind so concerned with obedience as to lose initiative? He felt a thickening despondency drive him down into a strange lassitude."
Second Foundation by Isaac Asimov p33

In this video we learn how to recycle cardboard into durable, waterproof projects that can be built nearly for free!

Wheat paste based glue, UV protection, and non biodegradable alternative demonstrated.

Still planning on using cardboard molded stuff in my present projects, so this recent upload is very apropos. As a former pro automotive painter, I could easily use several finishing techniques to make far better surfaces than this video, if I was not so physically limited. The cardboard clay is begging to become heavier body filler, and a newspaper pulp would likely make a finishing surface.

 

Intending to reach anyone here with some product or industrial design chops but anyone with an input is welcome. I spent the day looking at all of the components I want to fit into an audio amplifier. It is somewhere around the size of a typical router. My ideas thus far are ehh at best. I just abstracted the realization that this is an issue common to most electronics products, so who does it best or what ideas do you like most for shapes and design?

 

0.25mm nozzle, clear PETG, Prusa, 6mm standard headphone jack, upcycled broken bluetooth headphones, three times larger battery, snap fit with no hardware, FreeCAD, 2nd print iteration, listening to it now, no tricks - it holds together firmly and is usable and actually sounds better than the original by a long shot from better headphone drivers I guess or proper soldering, oh and power button built into the flex of the design, OC only posted on Lemmy

Stupidity Epidemic? Are critical thinking, intelligence and civility on the decline?

Dude is not getting the views his content deserves for the quality and questions he asks and researches.

 

The info wore off the grip and I do not recall what it was. I think it was a German brand. These have been one of my favorite tools for a decade. The jaws are much more narrow than what is typical for side cutters and these handle like a surgeon's scalpel. Best of all, they can be sharpened many many times. Unfortunately, these are getting close to end of life from all of my sharpening and pivot pin wear. I want to get another set, but I have never been able to figure out the brand to find them again. They were given to me by a tech for a computerized Guru bicycle fit machine we had installed in one of our bike shops in 2012.
