Original brand or Chinese copy

[WM6]

I think anyone who gets their product manufactured in China or the far east, risks having it cloned and copied, no matter what patent laws they have in the west.

True, but don't blame Chinese, they simply behave opportunistic way.

Better blame greedy profit driven Neo-globalist, who kicked their own workers into the Road of the poor and humiliation.

Now Chinese kick back globalist greedy profit sack.

Right Karma at work.

I think you'll find not all the companies that have had their products copied are using Chinese manufacturers. The copies are either just plain fakes with a virtually identical outward appearance, but with completely different circuitry inside, or the original product has been acquired and back-engineered to be as close as possible.

This is another reason why most modern metal detectors are microprocessor driven, with all the important processing stuff hidden in software.

I remember once visiting a UK IC company that were examining a copy of one of their designs. The circuit was exactly the same, but the layout was different. Ironically, it worked better than the original.

In the same way a pickpocket or a burglar behaves. It is theft, plain & simple.

I've worked at White's & First Texas, both employ a lot of local people. Garrett does, too. Chinese counterfeits and copies directly impact these people. We could easily move production to China and compete on price, but then we would be a greedy profit driven Neo-globalist, who kick their own workers into the Road of the poor and humiliation. So to speak.

The counterfeits I've seen are absolutely identical. They exactly duplicate the molded plastic parts, but you can see by the injection points and ejector pin locations they are not the same mold (also, White's & FTP both mold their plastic parts in the US). There are now 3D scanners that can scan in a part and create a 3D CAD drawing, then create a mold design. The PCBs are likewise identical, it is a simple matter to delaminate & scan a PCB. So comparing a real vs copy, they look the same unless the copy uses some component substitutions.

This is another reason why most modern metal detectors are microprocessor driven, with all the important processing stuff hidden in software.

That's the easiest piece to copy. I am not aware of a single micro that cannot be hacked and ripped. At FTP I once sent a competitor unit to China, for $300 I got back the ripped binary and decompiled it to assembly. We then found that it was exactly the same as our code, so we sued the company and won. But they were in the US. Can't do that if they are in China.

China is communistic system hard nationalistic mandarin colored (not same like comparty of USSR). you did not live in this, i did live, i sure know.
look on all soviet chips and you will see just copies around from US made. ALL ARE COPIES.
when Stalin needed in good bomber for first nuclear bomb carrier he gave a command to copy american one.
the craft was copied in all tiny details - there were a toilet (wow! you must know russians do not do a toilet in military crafts) and... all bolts and nuts with inch metric.
the pilots were surprised looking that.

After all the effort required to design and build a new detector, it must be heartbreaking to see it copied that easily.

On a related issue, there are so many scams and rip-offs going on nowadays, but it was good to see this in the news ->

ALL ARE COPIES

Are you saying this seriously ??? Here is what the Russians invented and then stolen by the Americans:
1. Leonty Shamshurenkov --- self-propelled stroller
2. Mikhail Lomonosov --- helicopter prototype
3. Ivan Polzunov --- steam engine
4. Nikolai Pirogov --- anesthesia
5. Yefim Artamonov --- bike
6. Alexander Lodygin --- incandescent lamp
7. Alexander Popov --- radio
8. Alexey Pazhitnov --- Tetris
9. Bass & Prokhorov --- laser
10. Arseny Gorokhov --- computer
11. Boris Jacobi --- electric motor
This list goes on and on. We must learn history, and not deal with empty accusations ...

ok. compare them.

Can anyone give me an isolated drive circuit because my microcontroller power supply and coil voltage are isolated, thank you

[SWL]

To кт315...What are these videos for? You again litter the forum with your absurd thoughts (((

[kt315]

again just private attack on a personality. seeking fleas on my body. its bad that people try that again and again.

no pleasure

В прошлом действительно вся советская промышленность была построена на воровстве технологий. Самой известной из которых была технология производства атомной бомбы.

Средства доставки к ней — своровали тоже. Первый советский стратегический бомбардировщик Ту-4 был сворован с американского бомбардировщика B-29 по причине того, что одна из этих машин после бомбардировки Японии приземлилась на Дальнем Востоке. Скопировали все, вплоть до отверстия под стаканчик из-под кока-колы, которой у советских пилотов не было. Копирование было столь рабским, что все детали считали не в сантиметрах, а в дюймах.

Советская серия компьютеров ЕС ЭВМ была скопирована, тютелька в тютельку, с машин компании IBM System/360 и System/370. Что, собственно, и предоставило нашим математикам и программистам неоценимые конкурентные возможности в 1980-х годах, когда они стали массово выезжать на Запад.

In the past, indeed, all Soviet industry was built on theft of technology. The most famous of which was the technology of production of the atomic bomb.

Delivery vehicles to her - stole too. The first Soviet strategic bomber Tu-4 was stolen from the American bomber B-29 due to the fact that one of these machines after the bombing of Japan landed in the Far East. They copied everything, down to the hole for a glass of Coca-Cola, which the Soviet pilots did not have. Copying was so slavish that all the details were counted not in centimeters, but in inches.

The Soviet series of EC computers was copied from top to bottom from IBM System / 360 and System / 370 machines. That, in fact, provided our mathematicians and programmers with invaluable competitive opportunities in the 1980s, when they began to travel to the West en masse.

liudengyuan - you do not need to post exactly the same question in 5 different threads.
I have removed the other 4 duplicates.

I have a copy of gpx4500 with very stable performance and full compatibility with original accessories

[jinbiao]

China's gpx series copies are all orders from abroad, China is only a production base. There are many factories with production capacity, so the quality produced will vary. Some products are great and some are flawed. My friend has a copy of gpx5000 and cannot use an 18-inch single-turn disk ...
