"Long-Range" sensor projecs?

Is the long range in the room with us? It is I2C not very well known for long ranges. Especially with motors and electric drives and their EMI I2C is not the best decision.

From the title I was more in "Oh, what type of long range wireless they have opted for?" and didn't expect I2C.

For long range wired I would consider more a RS485 or CAN. Short ranges like in a small robot arm, a small car, and alike I2C maybe enough.

All are moving from monthly to usage payments anyway.

You use the model you need. You don't need to use always the top tier model for anything. That is your decision. You can use a top tier for planing and then the agents can use cheap Chinese models. Much more cost effective.

Why not using some other coding IDE with OpenRouter? There you can also use the models. You can even switch models easily depending on your needs and spent.

There are OpenSource versions of CodeX.

For example:

Be careful messing with your (modern) car like this. It may work at first glance. In some time in the future you may not be able to unlock your car.

As mentioned in the article as part of the introduction, there were problems with those car regarding security. Especially with the Rav4 where a colleague, Ken Tindell, showed a very serious flaw: https://kentindell.github.io/2023/04/03/can-injection/

Because of this OEMs build in more and more security, like SecOC with Autosar and other similar things. More and more of those security feature depend certificates in the devices that have an expiration time. Those certificates needs to be rotated regularly. If the rotation does not happen, because of missing communication with the mothership, then the security will fail, which finally will lock you out of your car.

That will be true for all the coming luxury car models.

IRC, Tesla has something like this for years in their cars. They can be offline for a certain period of time. But when this runs out, you will be out of luck.

Yeah, and I have the feeling it is not tested at all.

It offers Word -> PDF conversion. Just for interest I tried it and it doesn't even get the simplest page right. It puts the filename into an header. The test page had 4 images, one svg, one pdf (from svg), and another variation of the first 2. The generated PDF only contains 2 of those images with wrong sizes. The later two are missing. So it's basically completely useless.

The free of charge LibreOffice gives much better results with its own caveats.

Actually, you can buy only the 2024 version of MS Office for Mac, while the subscription is more up to date. You cannot buy a packaged 2025 version.

I feel like some HN posters simply read news and don't work in the industry and have actual insights on what's happening.

Like Hydac moved some of there assembly from China to Germany.

A company in the district nearby, just moved their whole production from Thailand back to here. Yes, production costs are higher. But there is not transportation costs. They don't have long lead times anymore and can react more better to demand. So the overall costs assessment lead to the decision it is better to have production here locally.

I recommend to go to SPS, Agritechnica, and so and talk to actual people.

BTW: Even as Continental has layoff. There are other companies around that happily absorb those people. Because 2 years back, that had problems employing people.

I can't share the name. I don't know their prices. I know that they are in Eastern Europe.

From my knowledge, the last time (2022ish) we talked about that was, that they don't take new customers for now. They are working at capacity.

I work with companies, which have a more like small scale production. They are about 100 or so workers. Yes, this is also possible. They grew their business in the last 25 years, when it was even harder to produce something than these days. At least one of these business have PCB suppliers in the EU, which helped them in the post COVID crises where everybody struggled with supply.

I just named some big name brands. I also know mid-size and smaller brands.

Building your business and getting your stuff together is hard for any startup in any business field.

Funfact: If you are working in the industry, you know that there are many companies who produce electronics in Europe in general and some even in Germany.

Bosch, Continental, Siemens, Palfinger, FAUN, Webasto, Phoenix Contact, Beckhoff, …

For a long time many German made car like from Audi, Seat, VW, BMW hat just one reverse light. On the left side is the fog light and on the right side is the reversing light.

You should read the whole article before claiming things.

After the 2019 closure of the Puttgarden-Rødby service between Germany and Denmark and the seasonal Sassnitz-Trelleborg route linking Germany and Sweden in 2020, the Intercity is now the last one running. All the rest were replaced by bridges or tunnels, or proved too expensive to maintain as demand fell in favour of air travel.

Yes and no. The prices are increased about 1 month in advance. With that the average price of the last 4 weeks is increased and then you have your rebate, which is legal.

How is it the death of documentation?

You can start off just with documentation and then in the process check if the code is still in line with the documentation.

You can also generate documentation from the code. Then check yourself, if it fits.

The HTW Berlin has a autarchy calculator. Unfortunately only in German language: https://solar.htw-berlin.de/rechner/unabhaengigkeitsrechner/

They also test and publish yearly the latest battery combos.

I see their board uses a daughter board from Phytec, a German company too. This is based on very high performance NXP MCU, the i.MX 6UL, with additional external DDR RAM.

Actually it is. If you want to build a cheap sensor or actuator, than any additional component is getting expansive. Remember it is not only the external component, it is also the PCB space, is the production, and the testing after production. This adds up all to the costs.

When you use a µC to make it cheap, then you don't want to use additional components.

No, Apple push cannot use SMS/Text. You need a cell modem to have working SMS/Text. Except the phone itself, most of the devices have no cell modem. Then Apple would need to keep a directory of all the cell phone numbers, because that is the way how the cell modem is addressed.

Well, then would work for less then 50%.

The majority of end user devices are run from within private networks protected from the Internet. If you have connected to your cell provider, then in the majority the cell providers are running their own private networks. For one reason the IPv4 address space is limited as such, that there are no other possibilities. IPv4 is still the important protocol compared to IPv6. Second, it is that those providers, want to protect you. Some don't even allow cross communication.

If you devices are connected with Wifi, then there is the very same situation. There is almost no campus, commercial, and home network, that gives you public route-able IP addresses. I only know a view deployments were you get public route-able IP addresses at conferences like C3, EMF, and alike.

tl/dr: No, the end user devices is not easily to reach without additional infrastructure.

How do you think push should work?

Any push service works this way. The client contacts the server to be updated. The server gives a no data or a data response. The server cannot magically contact the client.

At least here in Germany, you shouldn't use your home address for your business at all, because of Tax obligations, at least when you are not renting.

Because if you want to move your business later, when it grows, the tax office will regard your home as part of the business. Things will get complicated that way.

This adds complexity and with complexity there comes a price tag. That would make the key fob more expansive. It also adds higher power requirements this then comes with new requirements for the battery.

Funfact: in the past Ford and Volkswagen had only a number of different variations for the coding of the physical keys. So that you could open and start several cars with the very same physical key.

I assume that this was also true for other brands.

There is another issue with all those growing 2FA/MFA protected accounts: managing your unexpected death.

How do you teach your beloved ones to access your accounts. And they need to remember what to do. For some accounts may it doesn't matter. For others that means to be able to end the subscription. Because not all subscriptions are associated with a credit card, which just expires.

But if you allow to contact a company by a third party to cancel and or change things then this becomes the go to for social engineering.

Nope, the GNAV message is not only the position of the sateellites, the almanac https://gssc.esa.int/navipedia/index.php?title=Galileo_Navig...

Spoofing of Galileo was possible as long as the authentification was not enabled. https://www.septentrio.com/en/learn-more/insights/osnma-late...

https://gssc.esa.int/navipedia/index.php/Galileo_Open_Servic...

Galileo was the ugly duckling for a very long time - but it turned into a shining one after it aged a bit.

Yeah, for some time I was also in the camp of "why we need our own expansive service". But the current development has shown, that it was a wise desicion to have our own system.

BTW: thanks for updating on some other details. I never followed up really, it was from the initial plans, that I was told there should be comercial service, that should pay. Also that for some emergency services there is a very limited possibility to have a back channel.

What I don't understand about this GPS spamming: we don't need to rely on GPS. We have Galileo, (GLONASS) and BAIDU. That is the reason we its now called GNSS.

Most of the chips and as such the receivers are supoorting all of these systems in parallel. While I understand that the Chinese use their own coordinate system, I don't if BAIDU is based on that or not. Galileo is available. Galileo is able to use authenticated signals. Galileo has much improved over GPS. I assume in (important) comercial applications like aircrafts, you could use the better Galileo service for which you have to pay for.

So how important is GPS spaming really?

BTW: Samwer didn't made there money with Zalando. They made their money with a copycat of eBay and then selling it to eBay. They made that with many business. They made copycats of successful US business in other countries and then selling it back. Then they made there money with the Ringtone business. All this was way before Zalando.

You could argue the same with Elon Musk. Just remember he was a given by his Fathers mining business in South Africa. He was doing imposter with Zip2. But he got in early with Peter Thiel and then finally became the Paypal mafia.
