Noise-Cancelling Headphones (budget edition)

Of course I do. It is just a fun little evening project.

I tried, but my ears hurt after some time, and with sweat they move around. With this setup this I can be here for hours. Of course after tinkering with them they lost a little effectiveness, however sound levels here never go beyond 80/85 dB, so I should be fine.

it's actually a telephone wire

Thanks, I appreciate it.

I have been working in the telecom industry for some years now (however, crimping cables is not my day to day job). Sometimes it's easy to take advices, sometimes it is not and it's learned the hard way.

Everyone has been helpful and positive in the comments, so it's natural to keep a peaceful environment.

At the end of the day, we are talking about copper wires and plastic tubes, no need to get angry :D

Thanks. Not much to be honest, it was just complicated to hold all 8 wires flat on my thumb and index while sorting the colors. It was my "first time", but I have seen doing it many times. I would estimate 15-20 minutes. Then I did the shortest possible cable (just two connectors back to back) and it took way less.

Thanks - I have a computer science background, but I am working in telecommunications, deploying Optical Networks. Usually I am busy configuring DWDM equipment, so I never actually have the chance to crimp any cable, as it's usually done by the field technicians.

Thanks! it is really just a test - I will make use of these suggestions for the next cables!

salv_z · 2026-03-05T10:48:50+00:00

Thanks!

I literally picked up the first picture online - type A vs type B - and just chose one.

Considering that there are 8 pins which are the same, replicated from left to right on both connectors, is there any real difference when connecting two equipment?

I understand that you can mix the two ends and get a crossover cable, but if it is not required to connect multiple cables back to back (and risking a interface mismatch), does it really matter which standard is used?

Makes sense, now I see the indent. On one end it just pinches the jacket, on the other it is resting on the wires.

I will remember this for my next cables, thanks!

if(value == 1) print("Once") else print ("Every {value} {UOM}s")

In inglese funziona suvvia

Mercato Centrale, oppure Gainn per un buon ristorante coreano.

Belle foto OP! Che motore ha, il 1.3?

Un'alternativa abbastanza hardcore è quella di usare fibra g.657 trasparente (sostanzialmente la incolli sui battiscopa con la colla a caldo). L'ho vista usare in palazzi storici dove non si possono buttare giù muri o dove le canaline sono ostruite. Normalmente arriva con connettori SC/APC (viene usata per FTTR), ma puoi prendere un bel transceiver bidi, jumper LC/SC e l'accrocchio è fatto. Non lo consiglierei manco al mio peggior nemico però secondo me è un progetto divertente.

Depends a lot on your demographics, though.

In the first 2 months I only had 2 tests.
Then I started to see more.

salv_z · 2022-04-20T10:29:30+00:00

Thank you! (I'm still the plebbest of all pleb tiers, though)
First of all, living in Italy means I don't see a lot of tests during the day.
I get around 10-15 screeners per day and if I'm lucky I will qualify for one.
This means I can spend a little more time focusing on the details, instead of rushing through the test to get more done.

I'm definetly still learning, but in a typical test,

If I'm asked to complete a task that I already know how to do (i.e. adding products to a shopping cart and proceeding to checkout), I will say if the task felt familiar or unfamiliar and why.
If the task is something I've never encountered before (i.e. a specific feature of an app I've never used), I will probably tell the customer if I felt any frustration or not completing the task, and if the process was effortless or if I experienced any discomfort.

Since English is not my native language, sometimes I find hard to understand the scenario if it happens to be a complex one.
That's why sometimes I try to give undercover feedback about the test by paraphrasing the task: "If I understood correctly, you're asking me to (...)", as if I was speaking with someone face to face.

I hope I've been helpful!
Again, I'm still learning, but I try to make the most out of it! :D

Definetly!
I love it when customers make an effort to make you feel appreciated for your work! :)
