Zip ties is what we call them. Flush cutters help to cut down the possibility of slicing your hand open if your hand runs across the cut edge. I use power banks like those for various things including nightlights
Good haul today. The ideal that someone is selling a diy power bank box is cool. I have so many18650 lithium extra cells here. This gives them a new purpose. And we get to repair the broken power banks they send also. Lol.
The micrometer caliper and flush cutter are certainly winners! I believe those CH chips, like the ubiquitous ch340g serial/usb bridge, use the ancient 8051 instruction set. Should be fun exploring. Let us know if you can do anything with it in the Arduino IDE. Ah, I found the quote: "There is no free C++ compiler for MCS51 chip, we can not use polymorph functions." My 8 battery 18650 was also a disappointment. Could not make it faithfully deliver power for extended periods, as it tended to go to sleep. Rather useless as a UPS for a SBC server, or such.
Re: the powerbank. I think the test position allows you to quick check the %capacity (by way of voltage) one-by-one before installing the cells. It's a good idea to ensure the cells all have the same voltage. Once they are checked, start by installing the lowest voltage first and work toward the highest one. Sometimes these powerbanks require connection to charging before they will start providing output. Also, the capacity display will only be accurate after one full charge/discharge cycle. To all the onlookers: BE EXTRA SURE to not connect any of the cells backwards. Otherwise, have your fire extinguisher ready! The benefit of the plastic calipers vs metal is they won't be as likely to mar the objects they are measuring.
Thank you Kent for another year of exploring the wonderful world of cheap stuff on the interwebs, always interesting. As well as all the other things you do . Take care and happy holidays 🎄
That powerbank is only rated 18W output, 9V 2A or 12V 1.5A... nowhere near enough to power a soldering iron. You need minimum 65W (20V 3.25A) or preferably 100W (20W 5A) to get decent performance. Hard to find in a DIY case as it needs series cells and a Buck converter, rather than the simpler parallel cells and Boost. There is a good 100W module by TZT that supports 4S and 5S with balancing, or 6S with protection only. The PCB is too large to retrofit into these cheaap cases, but I trying to modify a 21 cell box to run 3S6P which should work for 20V down to cell cutoff. For these levels of grunt you really need good cells, preferably at least (budget) INR power tool type with 10A min continuous discharge. You need to be minful of voltage droop under load, and harvested old laptop cells usually have too much internal resistance to cope.
@@pileofstuff - once you get it open you will be able to get the chip datasheet. Most of these cheap QC/PD ones use an "Injoinic" brand all-in-one chipset, usually the IP5328P. The chips work OK, and often have programmable battery cell charging and undervoltage cutoff. However the output inductor is often undersized so the voltage droops under heavy load.
I have one of those calipers .. 5 years old, still accurate. I prefer them over my metal ones .. lightweight .. non conductive .. precise enough for what i do ^^
You said 'The calipers measure in both metric and American units' Come on, let's get this right. You should have said 'Metric and Imperial units.' The word inch is most definitely British (but of Latin origin, uncia, 1/12th of a Roman foot) although no doubt Americans will say they invented it along with the English language ;-)
@@pileofstuff was looking too suspect for me, Tbh the PD technology don't cost a lot, but the fact that all the battery are in parallel is definitely a no buy for me. 4v to 12v you have so much wast of energy really not a good way to do, be sure the next time you go with only multiple parallel of 2 battery. But I think it can definitely be a good project to do yourself for the channel 😉
I'm with you on my calipers always being where I'm not. Thanks for another great year of mailbags and here's to many more.
@9:00 it’s a case for storing dead batteries
That's an optimistic view!

In polish language we call them "trytytki" :D

Clone, third hand, or playing with editing? 😆 All the times I wished I could take a sip of my beverage while I sort through a pile of something!
Happy Holidays and wishing you a great New Year. I have enjoyed your channel.
CH552 is mostly used in those AliExpress macro keyboard, I got one of them wanted to make a video on it, but never got to it.
Normally the powerbank is sleep, to wake-up you MUST to connect to charge
hahahaha That intro camera work is brilliant, like you got an extra hand for Christmas! ! Merry Christmas.
It's a Christmas miracle!
Have a rocking Christmas.

Ahh, yes, the mini flush cutter. I always got one in my back pocket. Nice to have when you work at a second hand store.

Thanks for the Christmas video and all others. Best wishes to you and yours.
Merry Christmas and Happy New Year Kent. Looking forward to another year of videos.
Merry Christmas
Hopefully that onecircuit guy knows what he’s talking about! 😬
Merry Christmas Mr Stuff! 👍😀

If it's even capable of living up to it's advertised rating...

Wait! Did I see 3 hands in the opening as you grabbed your beer and cleared the desk?
Check the mat for a line where you can see the lighting difference between the masked takes
This why we never see his face... And lives on coffee flavored beer.
He's a ... you ... know ...
think I will pick up a couple of cheap calipers.
You got a good haul there. I look forward to see what you will be doing with items. Hope you have a great Holidays .
Merry Christmas!
The stuff is cheap until you run out of space to put it, merry xmas.
All power banks needs to be plugged to charge at least once to initialize the chip
Merry Christmas🎄🎄
Seems that there is quite a few micro breweries arround you, not the worst place to live🍺🍺
I do enjoy exploring all of them (and their wares)

Can you lean me your 2nd right one? 🤣
That's my beer drinking hand.
A christmas Monday Yea 🙂
Merry Christmas Thanks for the great year of vids. Does the power bank need to be full ?
Don't think so. All the cells are in parallel with no way for the circuit to know how many are installed. It should work wit only 1 installed.
@@pileofstuff ok will check out mine later got a few exactly the same will let you know 👍
This one seems to be damaged. The push button is missing, which should kick start it (and hold to switch on the LED)
@@johncoops6897 That's my starting assumption.

I'm just poking fun at them for using an archaic system that most of the rest of the world has abandoned.
God. 99 cents for a set of flush cutters. I could break a set every month and still be ahead on the deal versus going to Princess Auto
The mini flush cutter are so good, but also very recommended to put it in your multimeter bag
Merry Christmas 🎁
The caliper are still way better In metal
Yes, but there are many instances when you want to measure something but don't want the risk of scratching it with metal calipers.
They are for battery measurement too, they don't short electrical things. I have many of them for different things.
Don't like this changer look trash
It was the cheapest one I could find that advertised PD function
