NACKO T12K sting after several years of use, took it and cut it up

But everything seems to be of good quality. I have never regretted my choice, I think this is the best choice for T12 stings. As you can see from the saw cut, there is copper in the shell inside. I want to present for you a small review of the opened NACKO T12 K sting after several years of work. Well, it looks like the time has come. On the label, the designation HAKKO made in japan, the fonts are not erased, it is clear that it is a fake, there can be no original for such money. Everything there is done very well. At the same time and see how it works. But the price has become lower, I once bought for 328 rubles. I have been using NAKKO T12 soldering stations in my hobby for a long time. Apparently warmed them up for copying. looked, bent, tried to solder, well, it works, but somehow it is not stable. Remove the cap, it can be removed easily, just glued on As for the patient. The resistance of the heating element is 8.4 ohms, which is typical for these tips. So the thermal conductivity is good, which actually shows the operation. But then I defeated him, everything turned out to be not difficult, more on that below. By the way, now this seller sells stings already under his own brand. The metal casing is not magnetic, hard. At first I failed to separate from the metal part and remove the heater. and a set of tips, the most popular ones I have are BC2, D24 and K, for sealing multi-leg micro-wave BCM2 chips.
Magnets a little and then a small belt. Of course, inductions are all competitions, I hope this is the next stage, but so far they are too expensive for me. But the other day the station, when working with this sting, began to throw an ERROR error, this indicates a violation of contact. A well-known disease of these stings, a dump of welded contacts to the heater. There is no mention of Japan as well as the brand name HAKKO. Maybe nickel, did not understand.
Well, it worked for several years, you can say it paid for itself. I put another one, everything is fine, I bent the contacts in the handle, at first it was normal, then again an error. Now I have the main one on the STM32 chip, I somehow did a review on it. Number 1 sheathed copper, apparently nickel. Actually, a sting is a metal casing for protecting wires with a pen connector at one end and the sting itself with a built-in heating element and a temperature measuring element at the other. A soldering station on the STM32 controller, and not only me, there are probably a dozen reviews here.

This belt with the number 2 is magnetic, the rest of the parts are not magnetic In my work I use two pens for T12 It’s worse on the piece of iron itself Sting itself

Reviews of cordless angle grinders

Nickel-cadmium – heavy batteries with a long service life, can be used at low temperatures and charged up to 1500 times. In addition to the type of battery, the cost of wireless grinders also depends on the power of the device https://jiji.co.tz/51-soundcards/focusrite-scarlett-2i2, battery capacity, type of nozzles in the kit and some other parameters – everything is the same as with conventional wired angle grinders. The main difference between nickel-metal hydride batteries and nickel-cadmium batteries is their smaller size and weight, the technical parameters are the same. To do this, the device has a built-in battery, so you can work with it in places where there is no access to the electrical network. The most important part of such an angle grinder is its battery, as it determines the operating time of the device on a single charge. There are three main types of batteries in use today.

Reviews of cordless angle grinders

A cordless grinder is a type of angle grinder with the ability to work autonomously. However, you can charge them only when fully discharged and until fully charged. The most common are lithium-ion batteries, they have a long operating time, they do not have a “memory effect”, they can be charged and recharged at any time.

VGA>LVDS MT561-B adapter. How…

Pre-assembly before
inclusion.
Where would you start the process of making a display based on it? In reality, ADJ always has 3.3V when power is supplied to the adapter, 5V appears on BL during operation, and the brightness is regulated by means of the matrix, so the LED_EN and LED_PWM contacts on the backlight control board can be connected together. LVDS interface adapters are not uncommon these days. We begin to bring the device into a decent form.

VGA>LVDS MT561-B adapter. Matrices from new laptops, Macbook Pro and iPad. If you are not embarrassed by the lack of digital inputs and a somewhat strange backlight control logic, you can buy it.
When there is no input signal, the adapter draws approximately 210mA of current. To get a working monitor, it is enough to connect a matrix, a keypad, a 5V power supply to the adapter board and ensure that the backlight is turned on … and just with the backlight, nuances are possible.
We are looking for LED_VCCS points on the board – we supply 12V to it from the power supply, LED_EN and LED_PWM signals for a general check First of all, we are interested in the "Features" item of the "General descriptions" section. Turn off, rearrange the jumper, turn it on again. The simplest and cheapest ones process only a VGA signal, those that are more expensive can digest DVI / HDMI and play a movie from a flash drive. The current draw jumps to about 350 mA.
At this stage, the product looks like this: If someone will solder: We disassemble both matrices (I recommend before that wipe the table with a damp cloth and wash
hair so that dust does not fly from them). Finding a replacement lamp is almost impossible – the size 12.1" 4:3 is slow, there are no donors, it makes no sense to bring it to order too.
We take a file and saw through a slot in the tray from the gas discharge lamp to skip the leads of the LED strip. The adapter supports matrices with resolutions from 640*480 to 1920*1200 pixels. TMDS interface.
The remaining pins of the connector are used for the I2C interface, which provides data transmission about the display. In any case, supplying only power to start the backlight is not enough, control signals are also needed. At the same time, the load capacity of the BL output of the adapter is not enough, therefore, to generate a backlight control signal, an emitter follower with a voltage divider had to be used as a load. They connect without much difficulty, there are LVDS adapters for every taste and budget. In general, our case. This makes it difficult to use them, because the selection of the firmware is not obvious, and the procedure itself is not always complete without a programmer. Judging by the current consumed, the inverter immediately goes into protection.
The red 6-pin adapter board connector has a pair of pins labeled BL and ADJ. from the point of view of logic, a high logic level must be maintained on the BL pin during the operation of the adapter, and on ADJ, the PWM signal or constant voltage, depending on the brightness level set in the menu, must be maintained. In today’s review – an adapter that does without such difficulties. 1. TTL interface. Perhaps this artifact will be useful to someone. The following picture is circulating about this board on the Internet:
And we https://jiji.co.ke/computers-and-laptops/acer set the jumper incorrectly, and the adapter is trying to push the 8-bit signal into the 6-bit interface. 3. eDP interface. Such a backlight rarely fails, its power is separate from the matrix itself, although it is supplied through the same connector. After that, the backlight board can be isolated, and the wires in the bundle to the keypad can be replaced with MGTF 0.12. Its configuration comes down to installing several jumpers on the board. For other matrices, the number of lines involved may be more: The vast majority of used matrices are from laptops and monitors.
When placing the jumpers, keep in mind that usually matrices from desktop monitors use 8-bit color coding and 5V power supply, while matrices from laptops use 6-bit and 3.3V. In the first versions of VGA, they were absent, so if you suddenly have to solder such a cable yourself from the old one, make sure that the connector has a full set of contacts, and there are enough cores in the cable, otherwise Plug
jumpers for specific matrices. On old matrices, the backlight is provided by a gas discharge lamp, which is powered by high voltage from a separate inverter, which is located next to the matrix and is connected to it through a two-pin connector.
Conclusion: the adapter is fully functional and easy to configure. An example of use and some difficulties that you may encounter in this case are under the cut.
You should not be guided by it, because the names of the contacts in the connectors are distorted on it.
We glue the LED strip onto it along with There is no single standard – the control board was designed for a specific matrix. Outwardly, the picture looks like colors with a greatly reduced bit depth (for example, if you set the color depth in Windows to 4 bits instead of 32).
We assemble the matrix and check the operability of the backlight assembly. The donor board with buttons turned out to be overcomplicated, so I decided to transfer them to textolite. Oh, it’s alive! The source material will be a matrix cable from a laptop. Matrices with this interface, as far as I know, were used in the Apple iMac G4, iMac G5 and early iMac Pro. 4. LVDS interface. If you apply an 8-bit signal to a 6-bit matrix, the matrix will show a brutal kaleidoscope of colors, but there will be no correct image. They are almost identical in length.
It shows that in our case, to transmit an image, it is enough to connect the wires for power, ground and 4 differential signal pairs – 3 for data transmission, 1 for clocking. We cut off the connector from it, which was connected to the motherboard, we clean and service the wires, then we read the description of the matrix further. As a tester for LCD matrices, for its price, the adapter is almost Yes, the LED strip from the 11.6" wide-format matrix is ​​almost the same length as the lamp from the 12.1" square one.
It looks much better this way. On newer matrices, the illumination is carried out by an LED strip, the control electronics of which are almost always located in the matrix itself.
Among other things, it will describe the type of interface used by the LCD matrix. Both the lamp and the inverter can fail both together and separately, and without a working backlight, you most likely will not see the image on the matrix.
We are looking for a technical description for a 11.6" matrix. The numbering of the contacts on the comb and the areas for soldering the connector for a flat cable goes in opposite directions.
If after a while the signal does not appear, it falls asleep and reduces the current consumption to 12-15 mA. First, let’s take and cut off the extra textolite from the backlight control board, otherwise it won’t fit in place of the old inverter. An interface adapter is not needed – such a matrix can be connected directly to DVI or HDMI. Replacing it with another did not bring any result – most likely, the matrix backlight lamp is to blame.
We collect the adapter, the matrix and the backlight inverter together, connect the power … and do not see anything. It will not work for its intended purpose, the only thing that can be done in this case is to sell it at a flea market. Matrices are very different, so adapters usually need to be flashed for a specific matrix. The main problem will be the cable between the adapter and the matrix.
Firing a signal to the VGA input. There are options here.
The backlight is powered by 12V (allowed from 5 to 25V), controlled by the LED_EN (general on-off) and LED_PWM ( brightness control) with levels of 3.3V (the maximum allowable is 5.5V, but it’s better not to). How to make an LCD monitor with your own hands.

It uses an analog signal to convey color information. There is no proprietary keypad in the adapter kit, but in The Internet has photographs of it from both sides, from which it is possible to reconstruct the circuit diagram. Here you can still click the menu buttons, but there is nothing to see here by and large. Be careful – the matrix from the laptop will not survive the 5V power supply. The matrix once stood in a very ancient monitor or laptop. I don’t have combs with a pin pitch of 2 mm, the experimental matrix is ​​old, it’s difficult to find a ready-made cable for connecting it to the adapter board, so you have to solder it. The VGA video interface was released by IBM in 1987 and has been in production for more than a quarter of a century – it only began to fall into disuse in 2015 (but there is still a lot of equipment using it). In the "Interface connection" section, there will be something like this table.
We solder (preferably under a magnifying glass), rinse. 2.
The main problem was the search for a textolite 1 mm thick, I had to glue from 2 to 0.5.
nothing complicated – just five buttons that close to a common wire, and a two-color LED. They allow you to turn a separate matrix into a workable display or bring a monitor with a failed scaler back to life.
Serving food.
Oh, what’s going on with flowers here? In fact, such an interface consists of only 6 wires – three color signals, two synchronization signals and a common wire.
We take a tester and look for matching contacts on the board. This is explained by the fact that, according to the above picture, part of the complete picture does not reach the matrix (because the RX3 pair is not connected) – accordingly, part of the video information is lost. Of course, with the search for documentation.
Flip the matrix screen down, drive in the name found on the label into Google and carefully read the datasheet. But there are broken matrices 11.6" 16:9. So, you have found a lonely LCD matrix. If a 6-bit signal is applied to an 8-bit matrix, the picture will be correct, but too dark and no adjustments will be able to pull the brightness and contrast to the desired level
Everything works, you can go further. You can connect to DisplayPort through a passive adapter, to everything else – through an active converter that costs about $100.
