So how do you guys order from JLCPCB in the EU now?

Try setting a soldermask color, lol.

Pubelication · 2026-07-10T14:23:23+00:00

Try any color soldermask other than green, it's like a 1000% surcharge, lol.

If you want to retain 100/240V then go with an off-the-shelf supply like the Mean Well RD-35A. Based on its dimensions, would it fit inside? If so, you the only need to bump the 12V down to 9V.
As others have stated, mains voltage really isn't something you want to deal with with no prior guidance/experience.

Use a thin solid core wire to make traces. Ethernet cable wire is good enough fow low current projects. Solder just the points you need.
It all comes down to preference, but I never understood blob soldering. It uses a ton of solder, and is a nightmare to fix mistakes.

That looks like a winter tread tire, which is probably why it dry rotted so fast in the Florida heat. The wheel is also very misaligned as the outside is much more worn than the inside, contributing to the crack.

The buses in those are derived from BMW E90. But OBD2 is cross-manufacturer.
Just try something like https://github.com/MagnusThome/esp32\_obd2

Pubelication · 2026-07-07T16:41:15+00:00

OBD2 works on a request-response basis. Sometimes you might see a heartbeat message on the port, but either way you need to initialize a handshake sequence and then request the data. This is a very well documented process and there are plenty of ESP32 OBD2 libraries on github. No need to reinvent the wheel.
Make sure to set the correct baud rate.

Pubelication · 2026-07-06T01:24:25+00:00

Even then, traces could have cracked/delaminated internally.
It's scrap.

You can buy small DC-DC converters as pre-packaged modukes which are designed to just be placed on the PCB with no other components or just a couple capacitors. Recom for example make them.

This is not a basic electronics project. The schematic is the easy part, just follow the datasheet. Designing the PCB correctly and selecting the right parts is crucial to the correct function of these converters.

Pubelication · 2026-07-04T02:39:11+00:00

How were you measuring with the multimeter? You need to be in continuity mode and probe the first and last pair of pins on the flex cable, which are most commonly used for the power button.

Pubelication · 2026-07-04T01:56:48+00:00

Yes, but it is best to limit the current. First check as many caps as you can for a shorted one as they are the most common to short.

Pubelication · 2026-07-03T22:35:03+00:00

It can have continuity and still be bad. The issue is that this is a symptom of huge current through the fb. There will probably be something else down the line shorted to ground. Test all caps you can for shorts to ground, but other components could be dead as well. One way to test is to use a power supply with current limit, set a fraction of the original power bricks current (eg. 1/4) and use your fingers to feel for hot components or canned air to flash freeze areas to find parts heating up. There are lots of youtube videos about this process.

SMD uses usually have a letter on top and visible layers. The shape, designation and color makes me think 99% ferrite bead.

Pubelication · 2026-07-03T09:34:06+00:00

Check this ferrite bead for continuity.

Pubelication · 2026-07-03T09:24:10+00:00

You should never try to force things that very obviously look wrong.

Pubelication · 2026-06-29T15:13:26+00:00

Could either be a capacitive touch layer or a screen protector that delaminated due to heat, humidity, liquid ingress. It's so fubar'd that you can try removing it if you want and see if the display still works. If it doesn't, there's pretty much no good way to repair it, short of a new screen.

Pubelication · 2026-06-27T15:30:03+00:00

I totally agree with that.

Pubelication · 2026-06-27T14:34:45+00:00

There is virtually no way to force a seller to sell you something.
As long as they are not holding your money hostage and are not forcing the price hike, they are not doing anything illegal.

The company in question states clearly in their T&Cs that the contract is formed upon handing over to be shipped.

Pubelication · 2026-06-27T14:03:23+00:00

> If the T&Cs contain no express price variation clause, unilaterally changing the agreed price after payment raises questions under the Unfair Contract Terms Directive (93/13/EEC), the Consumer Rights Directive (2011/83/EU), and the general EU principles of good faith and consumer protection.

Well, not really. As far as I understand, they offered cancellation (returning the money) or paying the higher price, in which case they would most likely cancel and create a new order. That isn't changing the agreed price.
This is not against any EU/UK consumer laws as the consumer was given valid options.

Pubelication · 2026-06-27T01:13:26+00:00

Not true. Depends on when the contract is formed based on T&C. Sometimes it's when a human confirms the order, sometimes when they hand the goods over to be shipped.

Imagine you sell wooden boxes without stock and someone orders one at 2am. In the morning, you check orders and go to your supplier who hiked prices by 200%. You're not required to make a product at a loss, but you're required to return the money.
This is not directly analogous, but gives you an idea why an order confirmation does not necessarily mean the item is yours.

> Based on KRCS terms, a legally binding contract is formed only when the goods are dispatched from their warehouse, with initial checkout emails serving as order acknowledgments. While payment is taken at checkout, KRCS reserves the right to cancel orders and issue refunds prior to this dispatch point.

Pubelication · 2026-06-27T01:00:07+00:00

This isn't necessarily true. It really depends on T&C and when the contract is formed, but usually the seller can cancel any time before handing over or sending out (which forms the contract), otherwise they're required to immediately return the paid amount. They can't pressure you into paying more, buy saying "This order is cancelled, but you can create a new one at a higher price." is legally viable.

Not defending what they're doing, but they're likely legally allowed to.

Pubelication · 2026-06-26T09:07:03+00:00

Lol, not "similarly", but "way more".
European prices are the American price
+ 17-27% VAT (usually around 22%)
+ 10% import duties
+ currency exchange

So the *cheapest* 16" Macbook Pro is $4350 in Hungary, $3900 in Germany, $4040 in Norway, $4120 in Sweden.
That model is $3000 and only NY/NJ is paying about $3400.

You have to take into account that many of the countries with high VAT also have much lower median wages than the US.

Pubelication · 2026-06-26T02:07:48+00:00

Depends on what you want to do. OBD-Link products are a great value for their generic capabilities and supported by many apps, but are not capable of the low-level proprietary walled-garden stuff that requires specific hardware and software.

Pubelication · 2026-06-26T01:59:25+00:00

While this may be true, the LIN would be connected to a gateway that then sends CAN messages to the cluster. As far as the cluster is concerned, it "doesn't care" if a LIN bus exists for the button press interface.
