It's definitely 2000-vintage, but where are you getting Pentium III? It clearly says celeron on the sticker. The Pentium III's with a comparable clockspeed had a 50% higher FSB and twice the L2 cache.

What does equal population mean and what does the different widths indicate?

Are the widths just the original area? Because why then introduce the "equal population" information?

I'm sorry if I'm being a bit thick, but I really don't get it.

Nogen her der har en VW ID et-eller-andet? Jeg prøvekørte en id3, og AC var gemt væk i undermenuer. Da jeg forsøgte at sætte temperaturen, blev jeg mødt af en besked om at jeg trykkede for hurtigt under kørsel, og nu skulle vente 10s for at kunne trykke igen... Inden jeg kørte i den, ville jeg super gerne have haft den bil, på papiret stod der +200hk, baghjulstræk og en pris havde råd til. Men nu kører jeg Renault i stedet.

Jeg håber vi får en periode, hvor alting er tilbage i rigtige knapper, inden vi går over til autonome køretøjer.

Buh-frigging-huh! Jeg gætter på at en stor andel af de prostesterende borgere købte deres huse mens fabrikken stadig var aktiv, så at komme nu med protester er lidt for søgt.

Den fabrik skal ligge et eller andet sted, og alle andre steder skal man til at bygge først, for at have bygninger i samme standard. Stik piben ind og klap hælene sammen venner.

There was a time when all you needed to call in a prescription in Denmark, was the doctors authorization number... Which was publicly available. Sure if you called in a prescription at a pharmacy across the country or sounded suspicious, the pharmacy would make a call back, but other than that all you had to do was pick a doctor in an area with lots of other doctors and near a large pharmacy, and you'd get whatever you liked.

It must have been so for +10 years before a journalist and a doctor blew it up, by having the journalist phone in prescriptions for morphine, barbiturates, and other recreationally applicable substances. I don't know if a doctor can still phone in prescriptions, but the immediate stop gap was to only accept prescriptions accompanied by the doctor's personal, and crucially private, SSN.

What a mighty warrior, he'd be dead with the first chemical strike.

As was mentioned last time this was posted, it's a matter of being able to use gas masks properly. If the masks don't form a seal with the skin the wearer is dead.

When was the last time the US fought an enemy with a credible chemical stockpile? That's why it hasn't been important the last 30years. But Russia has shown to still possess chemical weapons and the will to use them. North Korea is known to have CW in their arsenal, and it would be naïve to assume that the PRC doesn't.

At the moment allies for WW3 are still blurry, but I guess it's better safe than sorry. So it's not a rule intentionally targeting black people, it's protecting all soldiers. The rest of NATO should probably enforce the same rule.

Tourism is down? No shit!

I'm in a situation where I might have to travel with a group of students, and big boss is dead set on the US. We're talking overtime, plane tickets, car rental, hotel, and a per diem. But still I'm resigning before I'll go to the US right now. If ICE or CBP sees 10% of the stuff I've said about TACO, and politics in general, online, I'd be lucky to just get shipped home.

IDK why you're getting downvoted, a large cargo ship can emit the same amount of co2 as 50 million cars https://maritimepage.com/cargo-ship-co2-emissions/

Perhaps the people downvoting you are the same kind of people without a sense of proportion, who think that turning off an LED light bulb saves the environment.

It could also be that you don't provide a solution. So here it goes: want to cut co2? Buy locally produced goods. If you live in the northern hemisphere strawberries aren't in season in January, and it's a good chance that neither are tomatoes or avocado.

Some media not showing (sh.itjust.works)
submitted 2 weeks ago* (last edited 2 weeks ago) by [email protected] to c/[email protected]

Seeing as I don't see others mention this, I'm gonna try and see if I'm alone in this.

Some pictures and videos won't show for me. It's not that the files have been removed, because I can download the files, but boost won't show them. Sometimes the pictures will load fine, if I choose the original resolution.

I figured that it was because I had an elderly phone, a OnePlus running Android 13, but now that I'm on Motorola running Android 15 I guess it has other reasons.

Anybody else have this issue?

Here's an example of a video that won't load it's NSFW https://lemmynsfw.com/post/27180424 come to think of it, I guess most of the stuff that fails is NSFW

Suggestions for birds? (sh.itjust.works)
submitted 2 months ago* (last edited 2 months ago) by [email protected] to c/[email protected]

I'm looking for suggestions on fowls.

We have a small flock of chickens, about 10, but we have another run with the capacity for about 20 more birds. We also have a small flock of ducks, a single muscowy lady and some indian runners. The ducks are our counter slug squad, but also provide us with some prime eggs as well.

Anyway, we're considering adding some quail as a pesticide in our ant infested greenhouse, and a few geese as lawnmowers for a very soggy part of the garden.

Besides the utility of the birds, we do expect to eat their eggs and come autumn fill up the freezer.

I think we've diversified quite a bit, but what do you think? Something that we should consider keeping as well?

Edit: removed the artifacts of my initial pre-posting edits

Question: If you have tried a dodgy dual input hotend, what were your experiences?

Background: As with anyone else who have a single extruder, I've been contemplating upgrading to something with a bit more flexibility. But the idea of getting a whole new printer doesn't appeal as much to my wallet, as it does to my mind :-)

Scouring aliexpress for weird filaments with the mrs - you know, normal Saturday-evening-and-the-kids-are-sleeping couple activities - we fell upon a dual input hotend for creality cr10. It looks an awful lot like the hotend we have, and it comes with either 24v or 12v heater. It's only about 15€ so I might just give it a try, but it's pretty stupid when I don't even have a plan for an extra extruder as well. And I don't know how I would go about wiring that part up on my cr6 at the moment.

In search of a dedicated small engine community I come here.

I have an older husqvarna frontrider with a hydrostatic transmission. While checking the transmission oil I noticed that the fan had broken of most of the blades.

Looking at the transmission cover I can see that it has been grazed by the blades, suggesting that the fan has been pulled sideways.

The oil check was part of a small service, that I was doing since I had to replace both belts going to the cutting deck as well as the belt in the deck. Those belts died when the belt tensioner, in middle of the mower, came loose and dangled beneath the mower.

My questions are these:

  1. WTF?
  2. If the belts have pulled that much in the engine driveshaft, as to do this, what else would you look for before starting the mower again?
  3. Given that it's about 10°C outside, would you run the mower without a fully functioning fan?
  4. Have I missed something? Any wisdom you wish to impart?

As the title states really. I need to refer to this diverse group of people, who somehow have gotten put in the same box labeled "sexual minorites".

I'm a boring CISHET vanilla white male, so I don't really know. I want to include as many as I can when I refer to "lgbtq+ people". I've been studying various flags, trying to find the one flag I need. But I can't really figure it out.

Is lgbtq+ the preferred term, or what should I use? Is a flag better? I don't want to hurt someone by not including them.

I apologize for the links below being vendor specific, but the linked products are the specific products I have used. I have no affiliation with the shop other than they offer to bill my job instead of having me pay upfront and then get the expenses redeemed. (I have tried making this both subscript and super script with respectively ^ and ~, but none works on lemmy)

I seek advice on proceeding with the setup and acquiring an acceptable printing quality.

Background

I have recently "upgraded" a creality cr6 se at work. I installed a spider steel/PEI plate (https://3deksperten.dk/products/spiderflexiplate-double-system-255x245-ex-cr-6-se), a bimetal heatbreak https://3deksperten.dk/products/3dsupreme-titanium-alloy-bi-metal-heatbreak-cr6-se) and a hardened steel nozzle (0.4mm from this kit https://3deksperten.dk/products/creality-3d-3d-printing-up-market-nozzle-kit-8-pcs)

Findings

Testing this new setup I used the PLA spool I had been printing with days before without issue. The new and old nozzles are all 0.4mm.

What I discovered was that I couldn't get any adhesion to the built plate, some spray glue (this exact make and model https://3deksperten.dk/products/printafix-100ml) fixed that. Then layer adhesion was an issue. So I upped the temp to the max for this PLA and increased the extrusion rate. First 10 layers or so were somewhat ok, but the rest delaminated instantly.

I then opened a brand new spool of PLA, thinking that the old spool had moisture issues. Cranked the temp to max, 210°C, added 5°C to the bed and applied a strong shot of spray glue. This time the print actually got done, but the parts where Cura's tree support was supposed to be supporting, the layers seem to come apart. The rest of the print was somewhat ok, though not great.

Current considerations

  • Maybe I attempted too much at the same time. I may try swapping the nozzle back and only deal with the plate and heatbreak.
  • The heat break may be install wrong. The nozzle was screwed in all the way, loosened a few turns, then the heat break was screwed in all the way. The nozzled was then tightened. No heating was done. I may try giving the heat break a few turns before installing the old nozzle again.
  • Should I have heated hotend before tightening the nozzle?

Simply put, our slate countertops are uneven, creating issues in daily activities. I've considered using an angle grinder with a grinding disc, but I'm hesitant. Seeking advice on practical solutions for making installed slate slabs even.

The slabs in question varies in thickness by at least ±6mm, in some spots the extremes are within 80mm of each other.

Looking to maybe upgrade my kid's creality cr6-se, so we can move into the more exotic materials.

It appears that I have two options for an all metal hotend, but I can't find any comparisons. Not besides a reddit post from 2020 stating that the Prima Creator is a knock off.

So have anybody tried one or both and care to speak about the experience?

UPDATE:

Never before have I seen an entire maker community go "WTF are you doing you MANIAC! Just frigging buy it instead". I'm impressed :-) Normally I have to solicit such a strong response, this was pure ignorance.

I don't know whether we'll go forward with the 3d-printing part of this project anymore. If we do, I do hear you on the PETG, and it's not out of the running anymore. I may take the project on in a much smaller scale, on my own dime, so I can still try out some exotic materials (ie not pla).

In response to the cost per wand. I've found mailbox red TPU72d from kungfuflex for about 43USD per kg. I made a mock-up of the wand with 2mm walls, and at 220mm length it comes out to about 54g per wand. That's about 2.5USD - if nothing goes wrong and I don't waste a spool by printing unattended.

I think there's still something to be said about being able to form the wand to fit snug on the specific flashlight. Maybe the solution will be purchasing wand attachments and making an adapter for them.

ORIGINAL POST:

I'm designing a wand attachment for a flashlight. The wand attachment will be about 170-200mm long, slightly cone shaped, and fit securely onto a given flashlight. When attached to the flashlight and the flashlight is turned on, the flashlight will illuminate the wand giving of a red glow.

The purpose of this is to use the wand for directing traffic at night. Don't worry, we're licensed to do so and typically asked by the police to do it.

See the picture for an idea of what I'm trying to explain. Disregard the tape and the fact that it's white PLA. The white PLA is what I had open and the flashlight is not the same as will be used with the final device.

The attachment will be produced in 70-150 copies and handed out to volunteers of my national guard company. The final attachment must therefore be able to take a beating, ie scratches, impacts, temperatures and various rough handling.

I have at my disposal a pool of +10 Cr6-se, one ultimaker s5 and one stratasys uprint se plus.

I'm considering a couple of material choices. TPU or PETG in a couple of the cr6s or PC in ultimaker. The uprint strictly uses some proprietary ABS spools, and all the filament I've got for that is ivory white. A buddy of mine has offered to print a release candidate in flexible tough resin. But I don't think that he has any idea about the scale of the project. So it really narrows down to TPU, PETG or PC. If I'm going to make this rigid I'm going to go for PC, for durability, or TPU for flexibility and durability.

I've found a source for PC in transparent and white and TPU (72d, 95a and 98a) in transparent, red or white.

I like the TPU72d in red, but is it the right material? I can't find anything on the translucency of opaque TPU. In the picture it's just 1 mm of opaque white PLA, but what about 2 or 3 mm of TPU? Should I just drop the illusions of red opaque TPU and print in clear PC and spray a coat of red paint on the inside? Or clear TPU?

WYD?

Flooded chickens (sh.itjust.works)
submitted 2 years ago by [email protected] to c/[email protected]

We had a bit of rain these few days. 110ish mm over the last 14 days, 25 of which decided to check in on us yesterday. So our run got flooded.

Not having the space for a truck load of woodchips, nor the time to spare, I got a couple of 23kg bales of sawdust. BTW .6USD pr kg for sawdust, what's wrong with the world?

The chickens were quite perplexed as to the bale when it arrived, and definitely not sold on it either when I had spread it out, pic in comments. I'm going to see how it works before spreading another one.

Usually I don't have to pump water from this area before November, but I guess that life ain't fair and the world is mean, so we started the pump this morning. Next 5 months (we'll I guess it'll be 6 months if luck be) we'll be pumping about 26m^3 from this area daily.

There's a Danish children's song that starts with something like "The farmer is always busy on his farm" and then lists the chores. I wonder why I that was stuck in my head as I wandered about the hardware store looking for bedding material.

Questions:

  • Can you test 450V high ripple current caps with a any old desktop RCL meter?
  • Has digikey shipped me faulty units?

Background:

I've gotten a couple of 660uF (not a typo, it's some weird high ripple current caps for an outdoor AC unit) 450V caps to replace some that I decided were duds. Normally I only measure components when troubleshooting, but this being 20USD with vat devices I thought "what the heck, I better".

The caps in question are chemi-con EKHJ451VSN661MA59M https://www.digikey.dk/en/products/detail/chemi-con/EKHJ451VSN661MA59M/17728502.

Method:

I'm using a Phillips PM6303A, which is a 1kHz RCL meter. Ambiant temp is approx 15°C. The caps have a 20% tolerance, so capacity should be >528uF, but when measuring both caps settle at approx 450uF after a little while. After 16hours it hasn't deviated for the one cap I've left in over night. The dissipation factor, tan(δ), settled at 0.57, while the datasheet states that it shall be no greater than 0.2.

For comparison, the caps I thought was faulty, have been running for about 20years, with the same specs, but came out to 550uF and 0.3, and as the spec said 0.2 I decided to change them.
