We are working hard to install all 8 V2X nodes into their Smart City Boxes today!

This is just the beginning. We're testing the first batch. More V2X nodes will be placed into their Smart City Boxes, soon!

A first batch of V2X nodes is making its way into the field!

Specifically, it is going to our 5GoIng Smart City Boxes [1], which we have already set up at the IN-Campus [2] in Ingolstadt. They form the heart of the system and handle 5G mobile communications, V2X functionality and the control and monitoring of our solar-powered lighting boxes.

The boxes are approx. 1x2x1 m in size and have solar panels and lighting elements that are directed at the nearby roadway. This allows us to trigger various lighting scenarios on command - for example, if two road users are approaching at dangerous speed at the traffic circle.

Sometimes even the software developers at @zeroiee get really sweaty.

For example, when rolling out updates, before presentations to customers - or when it comes to carrying a 12 kg car battery, a V2X radio receiver, GPS antenna and laptop across the nearby terrain to perform a range coverage measurement.

We certainly got a lot of looks during the event. Hopefully we didn't scare anyone.

The results are not yet what we had hoped for. But that's why we do such tests: to ensure that the customer receives a product that not only meets their expectations, but also delights them.

Smart City Boxes in the wild!

In beautiful and sunny weather, we set up the first four SmartCity Boxes on the Digitales Testfeld "ErsteMeile" (test field "FirstMile") in Ingolstadt, 🇩🇪 .

We developed the boxes as part of the #5GoIng project and improved them in several iterations. They are completely energy self-sufficient and designed to visually warn vulnerable road users using a special feature of the 5G technology.

For this to work reliably, tests are still required and planned with the rest of the infrastructure of the test field.

As you might know, our website https://zero-iee.com is a static web site generated by Hugo.

We want to use symbols such as a check mark on our pages in the future. The easiest way to do this is to use the appropriate UTF-8 character code in our texts.

Unfortunately, however, web browsers display the symbols differently - the Edge browser on Windows, for example, displays them in purple (dark mode) and Firefox onUbuntu in gray. This does not always match our color scheme.

That's why we came up with a workaround for Hugo that simply replaces all UTF-8 checkmarks with an SVG graphic and replaces them in the text of the page ($content).

Hey Mastodon users!
Have you ever seen an Audi e-tron display Mastodon on its main HMI display?

Probably not!
This was enabed by one of our products - the ZERO FPDLinkNode, which is part of our AMPS (Advanced Modular Prototyping System). The FPDLinkNode is plugged in between the native vehicle display-/touch unit and the HMI controller. This way we're able to manipulate display contents and create a visual overlay.

The overlay enables us to display the vehicle's own content and at the same time show new content on the display without disrupting the native functionality. In this example, however, we have set the FPDLinkNode so that the native Audi user interface is completely overlaid.

Weißwurstfrühstück and get-together 🥨 🍺

Compared to English, the German language is infamous for long compound words like "Weißwurstfrühstück". But the latter actually exemplifies that sometimes it is just cumbersome describe something nonexistent in a language/culture.

Weißwurstfrühstück is a Bavarian tradition and can roughly be translated to "veal sausage breakfast with wheat beer, pretzel and sweet mustard"". And we had a great one last Friday!

To this occasion, Johannes Sendtner, whom we supported with his Bachelor thesis, came to visit and proudly showed us his bachelor's certificate. He was evaluated with 1.0 for his work on optical air quality sensors.

Congratulations and good luck with the next steps in your career! 🥳🎉

We are currently testing the use of Hugo with the Docsy theme for the distribution of manuals for our products.

Since we already use Hugo to generate our homepage and blog, it made sense to use a tool that we already know.

The biggest advantage of a static site generator like Hugo is that we don't have to worry about security problems in the web application.

❓ Which tools do you use - and why?

We try to share our new developments, discoveries and mistakes with you and look forward to a lively exchange!

From time to time we will also draw your attention to new blog posts on https://blog.zero-iee.com/en/. If you don't want to miss anything, you've come to the right place! :-)

With #LTE and #5g mobile connections, the demands on the voltage sources have also increased: In particular high peak currents of approx. 4 A @ 3.7 V and more can push some circuits and the voltage converters installed in them to their limits.

In the event of stability problems with mobile radio modems, it is therefore particularly worth taking a brief look away from the software and towards the hardware. Can the power supply really meet the high requirements? An examination with an oscilloscope shows even the smallest fluctuations in the millisecond range and can reveal possible problems.

In our specific case, we are investigating stability problems with a new modem, which can only be reproduced unreliably. In the video you can see that even small pings have a visible effect (voltage fluctuations of approx. 800 mV) on the voltage source.

A clean Git history is the key to successful teamwork and quick bug fixes. Errors can only be successfully tracked down if it is always possible to trace when and where code was changed by whom and for what reason.

🥴 However, in the rush of the battle, the changes that are packaged in a commit are sometimes not taken very seriously. Who has never experienced this? A change that is actually unrelated to the current work package has made it into the commit because the file has already been saved temporarily.

💡The solution: With an "interactive add" (git add -i), you can pack partial changes ("hunks") into a commit and specify line by line what should be included in the next commit.

We at ZERO GmbH have completed our first prototype to display our own content in vehicle on-board systems. The touch function of the display can also be used to write ZERO in the most beautiful font ✍️ 😅

So...why all this? With the help of our AMPS platform, our customer can easily show new designs or functions in a vehicle and bring them to life - without having to access the series components directly.

And "easily" really means "easily":
Connect computer viaHDMI => switch on via button or CAN => be happy 🥳

Curious about our ArtNet based light control system?

We've created a web GUI that enables easy access to various typical vehicle lighting scenarios. The operator gets instant feedback about the currently activated scenario.

Our layering concept allows prioritizing lighting animations and stacking them on top of each other.

By the way: Animations are provided as CSV files. You're free in choosing the tool to generate these.

We are making progress with our new ArtNet-based lighting control system!

The most important ArtNet frames are now implemented. We have also successfully tested the implementation of our new layering concept: Multiple animations (for example flashing and a "Welcome" animation) can now be prioritized and stacked on top of each other. In the video, the flashing has a higher priority and thus overlays the "Welcome" animation.

There are still bugs hidden here and there, but we are looking forward to presenting a first complete version soon!

Having power issues sometimes is the "It's always DNS" equivalent in the embedded electronics world.

When we wanted to put one of our customer projects into operation, we noticed strange problems with a Quectel modem that we had not had before. Of course, from a software developer's point of view, the software was initially suspected of causing problems. But slowly a different picture emerged ...

Read the full story and learn how important it is to always consider hardware when you're having software problems (and vice versa!):
