Take your seats at your monitors, dear friends and colleagues, all who are interested in the history of optics. Assembly of a specialized low-noise amplifier on the IC LM386. That is why this time we have to get acquainted with such a lens. History and design. And when in Kyiv at the Arsenal plant a line for the production of Kyiv cameras was mounted with these lenses as normal, he migrated to this wonderful camera. The Jupiter-8 lens, nee Carl Zeiss Sonnar 2/50, has truly revolutionized small-format film photography. Who doesn’t remember the famous Zorki-4 with https://jiji.ng/accessories-and-supplies-for-electronics/startimes an imposing huge blue eye?

However…
When folded, the suit takes up 2 times less volume than my previous suit, and weighs only 750 grams. I needed a tracksuit for a long time, but I couldn’t find anything nice offline, but I didn’t dare to take it on the Internet, I was afraid to miss the size. The costume sold by the seller is presented in 3 colors and as many as 9 sizes, from XS to 5XL, according to my estimates, this is 42-58 size.

The costume looks exactly like the picture. Neither the jacket nor the trousers have lining. Therefore, the suit was in three packages: common for 3 parcels, individual for the suit, and also in a transparent one lined with paper.
Toli is not my topic, if there is really nothing to write about clothes in reviews, just look, but on this

At the 11.11 sale, I ordered 8 different items from 8 different sellers, 3 of them, including the suit, were combined https://jiji.ug/257-human-hair/curls into one package.
Hence the lightness and small volume of the suit.
The tights have 3 pockets, 2 on the sides and one on the back. For height 170 and 50-52 size (I’m smaller in summer, bigger in winter) I took size XL.
The waistband of the trousers has an elastic band and a drawstring for fidelity. What according to the seller’s table corresponds to size 54, but the note indicates that these are Chinese centimeters, and in the rest of the world they are different, 1-2 sizes smaller.

Quality Baseus 3A (Type-C) cable for $0.99

– for $0.99 short for 3A.
At a current of 2A, the loss was 0.111V (calculated resistance value 0.056 ohms). For a current limit of 3A, the voltage drop is no more than 0.2V, which is also an acceptable result. I was lucky, Baseus got the original one.
The connectors are made in such a way that there is a smooth transition to the bandage on the cable so that it does not bend at the base. Fast charging naturally works (9V / 1.5A). The phone determines and requests how much it needs. At a current of 1.5A, the loss was 0.085V (calculated resistance value 0.056 Ohm). The old Orico on 3A and 5A proved to be not very resistant to wear, I’ll check Baseus now
Here’s what was on the site:
Pay attention to the scratch code to check the originality Appearance – a simple cable, the sheath is not plastic, rubber, does not slip. It is convenient to take on trips, wear it all the time, put it in an organizer or bags with gadgets. So you can take it.

Quality Baseus 3A (Type-C) cable for $0.99

Given that this is a really good cable, more of these are needed.
It came without a track, with the Baseus information insert
At a current of 3A, the loss was 0.184V (calculated resistance value 0.061 ohm).
I check specifically with a power bank, since it does not overestimate the voltage, and you can honestly check whether this cable will work complete with a power bank.
Calculate the cable loss
The length is even more than 50 cm, just the length of the connectors.
For typical values ​​​​when charging a smartphone (up to 1.5A), the voltage drop is minimal, when charging a tablet or power bank, the loss will be about 0.1V, given that most charges overestimate the voltage to 5.1V. 5.2V, this is also not a problem. There is a logo and the necessary information An even better option is Baseus braided cables. Branded packaging, with a zip-package, sealed.
In appearance, there is nothing more to say, it is made according to standards, nothing dangles, it enters the Type-C and USB socket without play, like all other standard cables.
In principle, this is a very good result. There is an embossed inscription Baseus < /p> I took it for certain purposes – to carry with me with a power bank (a short one is more convenient, and there are less losses), to charge the power bank itself (less loss – faster charging of a large capacity), and for a soldering iron (very critical to power).
Scan the code, we get a link to confirm that this is the original Baseus, and not a fake Chinese .
Characteristics of the Baseus 3A cable Test QC 12V/1.5A This https://jiji.com.et/shoes/puma-roma is usually seen on good 20cm Orico cables, for a 50cm cable this is good. This is a simple cable for charging devices. branded. The usual price is about $2-3, they sell for a promotion:
View from Type-c side The cable is really compact, I usually stuff these with gadgets with me. There is no braid, this is a budget cable. Health tests. This particular cable is sent with the TS80 soldering iron
All types of QC work with this cable. Support for 2.4A is also declared. 3A for meter cables. – for $1.59 long for 2A,
