econcon··on Amazon is handing out 'Thank you' t-shirts to warehouse workers as it cuts pay
It's not about any of them being evil.

I've limited money and I choose to spend so that I get maximum spending least within the legal framework.

And most of the Amazon basics item come from china too.

So doesn't matter who you choose, china is benefits either way.

If people are against Chinese currency manipulation, they should be against what Germany does.

Yes, I look for one that ships with Gati.cn it usually takes 7 days to arrive here.

Amazon India usually has same product listed for 2-3x the price.

Replying to the-dude

>For EU citizens, the EU is a labor transfer union by design. These 'imported laborers' were not forced, they took their chances

No it's not that simple, other EU countries had to open their market to technologically superior Western European nations who had better quality highly skilled labor and capital.

If it was simple, labor movement - I wouldn't even be bringing this up.

>Are you seriously suggesting it is a problem foreigners are not making up the board of directors of German companies

Yes it based on the fact number of immigrants Germany has.

>As a direct neighbor of DE ( I am in NL ), DE seems to have been very generous accepting refugees. A bit too generous for some.

It's just a knee jerk reaction to their aging population.

>Do I think this person likes, respects, and would vouch for me?

But do you know who else does this for you? A dog.

I've never promoted anyone who likes me or respects me or vouched for me, I promote those who are reliable and have have skills to achieve the task at hand, one who will not betray themselves or their company for some kickback.

>Bundestag MPs gave standing ovations for care workers. Meanwhile those continue to slave away for pennies, now more precariously than ever, while the next items on the MPs agenda are bailouts for airlines and fucking car manufacturers.

Slaving away for pennies and immigrant workers, anything sounds familiar?

Amazon atleast in India is not the cheapest option.

I usually buy stuff from Chinese e-commerce websites where you can find things much cheaper.

econcon··on Coronavirus Is Making Universal Basic Income Look Better
If prices will go up, some of the UBI receivers might want to capture that price increase by launching new businesses.

I think more serious threat comes from existence of global market. It means, the local supply does not need to react to local increase in demand but people elsewhere can capture that demand by shipping cheaper goods.

To make UBI work you possibly need to become an island or already have huge exports to offset whatever your population might be interested in buying from other countries.

This is not a fact/experiment based, it's merely a hypothesis.

>The more government is injecting money to businesses, society and people, the more expensive everything is getting.

It only matters to people who have lot of cash saved up. Value of their money might decrease.

But vast majority of population does not have cash saved up, they do not care about money losing its value as long as they are able to get more money today and buy the stuff they need.

Isn't it like dead cat bounce, where once demand goes down producers stop producing then supply is reduced even below demand levels, creating hyper inflation?

Usually when production decreases, cost of production increases - operation becomes less profitable and investor might pull their money and take it elsewhere. In some industries, margin might be so thin that once they lose economies of scale which comes with higher production, they simply may go bust or choose to stop, citing higher cost of inputs. This is what pushes the supply below demand level.

Also demand is usually established at some specific price, if cost of production increases, producer might have to increase the price and this might also put downward pressure on demand.

econcon··on Ask HN: What's your quarantine side project?
It's made up of 38CrMoAlA and treated with nitriding gas treatment to improve wear resistance and hardness. And it includes free shipping from china, it's probably 5-10kg. And includes machined nozzle too.

Wood drill has continuous flight depth while extrusion screw has 3 zones. In compression zone, flight depth is gradually reduced to compress polymer.

Other than this, I think you'll have problem with finding reasonably straight wood auger drill.

With precision machine barrel and screw, screw will not touch barrel wall.

You can experiment with wood drill and steel tube but I doubt you'll get consistent diameter filament with it.

If you fancy making cheaper one for small scale/personal use, try this one:

Wow that's great, I wonder how they modify the PET polymer, as I've been researching it's not an easy polymer to print with atleast not without the glycol modification which is usually sold as PETG.

Any idea how they are doing it?

I buy shredded waste plastic.

Which means = they take car dashboard, wash it with water/solvent then shred it into very tiny pieces.

I take it and dry it in oven then I put that in an airtight jar, and let it cool to room temperature over next 24 hours.

I mix it with some virgin plastic (also dried and stored in airtight container)

Then I pour the plastic into hopper and extrude it into filament.

This filament is made from recycled blue ABS: https://youtu.be/Xirli3qDJlU

econcon··on Ask HN: What's your quarantine side project?
I've a video in my post where I am creating filament and I also sold the filament on e-commerce websites.

As I read some women in the article are making as much as a talented ivy league graduate who joins a tech company.

It seems amoral to prevent them from making money, why don't we see it as a talent as we see "tech jobs" as talent?

Can it really do more damage than what tech companies specially one who pedal ads and sell customer data and give people anxiety?

Converting Plastic Waste into 3d printer filament

Project: https://medium.com/endless-filament/make-your-filament-at-ho...

Hopefully, this will reduce the use of virgin plastic for creating art pieces in 3d printing community and you might be able to create beautiful and useful things out of waste plastic while cleaning plastic waste from the environment.

It's a profitable business.

I worked on this in my free time during quarantine.

I want to make the project more accessible so people around the world can develop local recycling unit. There is lots of work which needs to be done including making parts more standardized, demonstrating how parts fight together in a visual way and also have a microcontroller firmware to control diameter of filament.

I need help from someone who can write Arduino code, mostly includes reading diameter from a guage and then change the motor speed of puller roller so that it stretches the filament if filament diameter is more than target and slows down the stretch if filament diameter is less than the target diameter. This needs PID control.

It's possible to do this if you've a shredder and sorted plastic waste.

econcon··on Role of Vitamin D in the prevention of Coronavirus 2019 infection and mortality
Isn't it that when someone is sick or their health is detriorating, the first thing that happens is that their body stops producing Vitamin D? And since they are not able to go out from that point it further reduces vitamin D?

Life is a open book exam. You are free to take any idea from anywhere, spin it around and make use of it.

And really what's the point of getting grade/scores in school, when we can teach kids to collaborate with each other and create great new things.

Not everyone will be good at math, not everyone will have same drive to study physics. But everyone of us might find smth interesting in a project.

We shouldn't be pitting students against each other.

My wife is much less anxious when I am around here. She's a kind of person who easily gets tensed and helpless when she comes across some stressful situation.

To change his all I've to do is just listen to her and offer her my view and usually she is able to fix all problems on her own.

I am one of the lucky people to have great wife who loves me so much.

300w*3 power usage is below 3kW.

It's in this article:

“Building Filament Extruder” https://medium.com/endless-filament/building-filament-extrud...

I didn't accurately measure it. My way of measurement is simply to run the extruder use current rating from clamp meter and multiply that by line voltage. So I guess the power usage goes down once heater reach target temperature. It's by no means accurate, only guarantee there is that the power usage will be below 3kilowatt.

Unfortunately I don't have good meter, the ones I order from AliExpress didn't arrive yet due to Coronavirus lockdown issues.

>Beside insulation, could waste-heat from cooling the filament

I've no idea. I've a water bath which in which there is a motor which simply moves the water from bucket into the bath then back the bucket.

>PS: the video was reversed, right?

No, the filament goes behind the spool so it appears as if the spool is unwinding.

I am recycling plastic into 3d printing filament with my home brewed machine:

https://medium.com/endless-filament/make-your-filament-at-ho...

Anyone who needs help building one for their community can reach out to me.

Plastic usually degrades when recycled, it loses its properties like strength. But 3d printing is a good area where recycled plastic can be used as lots of people use it for printing a show piece with artistic value, not for high stenght tasks.
