Lesson learned master Sorin, never soldier connected to live board, doesn't mater the device!! Each error you do is error that your students will avoid. You have superior skill of teaching. Gratings :)
i love every posting you have done...such a kind and composed and humorous person
Guys, when sorin was in the army they were training on hand granades, and one of is soldier friend of Sorin, throws a hand granade and it doesnt explode.Then Sorin says "dont worry let me repair the hand granade, takes the grande and dismantels its ignition parts and replace the detonator and gives back. His friend takes hand granade, pulls the pin and turns and ask Sorin "what did u do" . Sorin's answer was as usual i replaced the detonator with a Properly Calibrated Detaonator. Actually these were the last words his friend heard. Then Sorin scratches his head and says What did i do wrong, i just replaced the faulty part with a properly calibrated one. 🤣🤣🤣🤣 Sorin it was a nice video just wanted to make you smile with a funny imaginary story. Lots of love from Istanbul.
Greetings. I thought that Mr. only works with properly calibrated fuses made by him. I honestly did not realize that he was into manufacturing and then calibrating detonators as well. Laugh.
im from Turkiye too. Greetings from Antalya . if i bought an NLBA to this price, i would get crazy when it get burned and then this seller whose nickname is NipEmbedded
would come and said " this is very nice device but you broken it. No more battery analyzer to you sir"
sorin would skip the detonator timer with a properly calibrated instant exterminator fuse :), then when you pull the pin, poof, no need to wait for a failure, it ll instantly ground the person pulling it :)
That's hilarious
Sorin has the biggest supply of specially calibrated fuses in the world.
There is no place on earth that can teach electronic like Sorin
15:14 - To identify component google "s-manuals smd". Then you pick from table and see data sheet. UL26 is ESD protection device.
19:42 - I am maybe 30 years younger, yesterday I tried to do something I did 20 times OK in past, I made single mistake and I bricked board worth 3000 eur. At least I am not one of those that are scared to even try. Yes I will repair that board because everything can be repaired.
I was going to say there was no need to add the "calibrated jumper" wires in because the board shows the connections go straight through, therefore the UL26 must be an ESD device.
I'm trying to learn and visited this website, found UL prefix and looked through all the datasheets. None show a UL26 or any component with 6 legs. How did you determine what this chip was using this website?
Good to see you again, ive always watched your videos and learnt a lot, esp with your lovely personality, wish you the best my friend.
You are amazing Sorin. I wish I had your knowledge!
me too
Ground leak from the soldering iron thru USB to PC..I burned a NanoVna like that..soldering while was connected to PC...I found later like AC 80V from TS100 power supply to PC ground..
I like the honest (unedited) way Sorin does the video. It could be the battery voltage running down the earth of the soldering iron into the mysterious world of earth loops, and then (because of Murphy) pop up in a place where it can cause damage.
Just have fun, you are your best customer, I'm too. Before to fix we need to spoil some thingys, and then just repair it. Nice video. Thanks for share.
Ground loop problem,rare but can be explosive.
The USBLC6-2SC6 and USBLC6-2P6 are monolithic application specific devices
dedicated to ESD protection of high speed interfaces, such as USB 2.0, Ethernet
links and video lines.
The very low line capacitance secures a high level of signal integrity without
compromising in protecting sensitive chips against the most stringently characterized
ESD strikes
your calibrated solder was absolutely pointless... look at the tracks on the PCB 🤣 those pads ARE connected already.. the UL26 is just an ESD protection, no signal is going through.
As always you are the best!)
699 in the US..... Even Sorin has continuing education. I thought I was the only one.
This was a great video on what not to do & how to fix when you break it. Always learning right?? 🤓🧐
Now put back UL26 which is ESD protection.
• 2 data-line protection
• Protects VBUS
• Very low capacitance: 3.5 pF max.
• Very low leakage current: 150 nA max.
• SOT-666 and SOT23-6L packages
• RoHS compliant
Benefits
• Very low capacitance between lines to GND for optimized data integrity and
speed
• Low PCB space consumption: 2.9 mm² max for SOT-666 and 9 mm² max for
SOT23-6L
• Enhanced ESD protection: IEC 61000-4-2 level 4 compliance guaranteed at
device level, hence greater immunity at system level
• ESD protection of VBUS
• High reliability offered by monolithic integration
• Low leakage current for longer operation of battery powered devices
• Fast response time
• Consistent D+ / D- signal balance:
- Very low capacitance matching tolerance I/O to GND = 0.015 pF
- Compliant with USB 2.0 requirements
It happens so quickly to not think about possible ground loops and the risks that may come with them. For that reason I always use USB Isolators for my USB Meters & Programmer.
I have also experienced that state of shock while I was soldering the mainboard with the charger plugged in, and I was shocked so hard, my whole body shook,, it was like I was put on the one that is placed on the chest for another shock, and I was not it was moving for a few minutes, it was like that happened there that the parts were shocked,,
the same happens with the oscilloscope, you can break it if you don't get another power supply that is separate from the mains .. there are special transformers
An example of these special transformers? Interested to see what ppl use to isolate oscilloscopes
@@waynetaylor2784 Isolation transformer ( just a 1:1 ratio transformer with two seperate windings)
Nice video
hi love your style and content.please could you test the V difference between the ground and solder iron tip.
You can't measure ground potential difference with a multimeter, it requires a so called electrostatic voltmeter.
Hi, If you look carefully there is no broken path under the chip UL26 ( esd protection ) , so your soldering wire is useless. Next time no need to rush 😉
I am always frustrated by having to repair the tool that is supposed to be used for repairing. I get so mad and start breaking everything.
"God heaps shit on those most able to shovel it"!
Sorin is teaching me not to panic, when I have cracked that, I'll try some electronics.
OMG I'm just glad that happened to you fixer of all fixable :)
We have a romanian customer, romanian custom unlock device, and everything is fixed by a romanian guy. WHAT CAN GO WRONG
😂😂😂
Exactly, i should keep my mouth shut next time :))))))
@@electronicsrepairschool but that update...what a troll... :D
Hi Sorin
This chip is a usb to rs232 converter to be connected to a microcontroller.
The battery sensor line is connected to directly to the microcontroller and not to 232 chip.
In first diagnosis when there is no usb response to the computer means that 232 chip is not communicated.
Like arduino boards.
Best regards.
By chance don't you know what kind of a microcontroller is used in the box? Thanks.
@@igorchemmykelly7202 unfortunately
No
@@anwaraddasi8892 It's a pity. If only Sorin would be kind enough to check it in his box...
Dear.. from where i can get software and interface of battery programming and analyser after putting new battery how to reprogram.please make a complete video on this topic. Thanks.
Hello....... can you share how to open the BMS circuits of makita, miuwaukee, etc. batteries with the chip reset software EV2300, CP2112,........
Dokładnie tak jak mówisz na końcu. Masa z komputera to nie jest ta sama masa co neutral w gniazdku do którego Masza uziemienie grota lutownicy. Powstało napięcie które zniszczyło chip od USB.
Siema widzę że nie tylko ja tu z Polski
👌👌👌
After watching your video, I would say your soldering killed the surge protection (the chip in the USB data lines). The Chip was probably fine until you put 5V on the 3.3V pin. That killed the chip. Anyway, Its working again and we were remembered to be carefully with different ground potentials. Did you check, why these were so different? Shouldn't both be connected to earth potential?
The chip was already dead, so there was no voltage.
I didnt see the video, but if you had battery connected to the device when you were soldering it - you had common ground connection between battery and usb chip. Afterwards, when you touched the fuse with soldering iron, you shorted VBAt through mains earth, through USB chip (USB GND) to main ground, which killed the chip (did that a few times.. :S )
For the chip itself, would strongly suggest not getting it from china, had quite a few arrive somewhat dead - Chip itself works, but the moment you install driver driver itself states "Chip phased out in 2010, contact your supplier" and does not work, simply because its counterfeight
Kind of late , but the usb data tracks under that esd protection they got continuity, you didnt need to use any proper calibratred soldering wire, lol,
Could you make a diagram of this device? so that everyone could make such a device?
plz try to remove UL26 usb protection part
Yeah, dont solder on plugged in stuff... I've made that mistake myself and payed the bill for it.
UL26 = Low capacitance, Two line, ESD protection.
Data sheet online.
Original PL2303 chip from China is hard to find. Bought from five different sellers and only one turned out to be genuine. If anyone wants, I can give a link to the AliExpress seller from whom I bought the original.
'dis iz da reason i turned to CH340 instead of PL or FTDI stuff, mon!
peace! :D
Hi do you have a schematic
Our NLBA1 DEVICE HAS BEEN DAMAGED AND IT IS NOT WORKING
WHEN WE PLUGED THE ADPOPTER IT WILL BE On and green light show in device
But USB is not connacted to the Laptop
Whats the solution?

Hello bro I need bq40370 EVM software
1:58 - "We"? Do you have a mouse in your pocket?
well iam alot younger than you Sorin and i already burn things i mean alot
What screwdriver is that
Es226
Es126 I mean
Hi
it wouldn't have happened if you used a wireless soldering iron. 😁
+So it was NOT your fault ?
man i swear you are unlucky :D
Cip cip cipcirip
Chirpy chirpy cheap chip. Opened up the box and ic chip was gone. Aka Middle of the road.
That device is too expensive. For what it costs I could buy 6 battery packs. Maybe a repair shop could use one but even then the cost is prohibitive.
NLBA1 is the most advanced laptop battery analyzer on the market, it is a real PRO tool, you pay once and you have it unlimited, lifetime. You can do tons of things with the analyzer.
Separately, if you want to repair batteries, you need a license per year which has a good price, the price of 3-4 batteries while you can repair hundreds or thousands.
To buy 6 poor aftermarket low quality batteries ? instead of repairing the original batteries ?
@@nipembedded9976 Do you need to have the internet connection in order to use the box or it can work on its own? Thanks.
@@igorchemmykelly7202 Internet is required.
LOL. blaming it on ground potential and electromigration
The whole machine has problems
Yes, people who don't have it says so.
hello soryn i actually have some god working devices , can you help me pleeease :=) lol I can relate , why me ! Greattings from françe .
Hello Sorin, I am from Kashmir India , i am an electronics engineering graduate and running the same business as yours and love to learn more electronic just like you. But the problem is that, here there are not many devices to fix and also earning is very little. Can i get a job in UK in the same field, can you suggest me something?
lol
finally opened it haha you are now been forced
Over priced and now we can see not the best of designs either
he broke it, it didn't just break, same argument for phone screens, "badly designed" because they break when you drop them
@@agutek proper octocoupler and it wouldn't have broken, common rookie design mistake to save few bux.
@@waynetaylor2784 I agree, it could've been improved, and it probably will with future revisions, but it's still user error regardless
i want this tool, but it is 700 bucks in the united states.....wtf
some people on here trying to tell you about electronics sorin .... !!! they couldnt tie your shoe laces ...
i got one never use it cant even sell it locked to my pc peace junk money making scam
You are wrong, the device can be used on other PC, unless you did dirty things :)
@@nipembedded9976 can you go into more detail about dirty things i dont get it
@@bitsnbobs1969 Like having sex with it. Not in the sence everybody would have thought.
Maybe it's time for you to retire.
UL26 is a Resistor Network
This device is so expansive but doesn't have optocouplers to protect the data inputs? That's stupid in my eyes.
@Ed Straker Ah right, very low capacitance ESD protection..
@@jonnygudman1815 a good reason for them to manufacture a second version of this useful tool :)
@@jonnygudman1815 if it were resistors , i think u will not get values and the chip doesn't function properly
@@jonnygudman1815 exactly you would have thought it was given
1:12 manufacturing in Romania maybe does the reason !!! ))))🤣
