Developing a product and supporting an open source project at the same time? In this interview, Lukas explains how and why he works on the Linux kernel for KUNBUS – because he doesn’t devote himself to it exclusively for the sake of the company. Can you give us a brief insight: How do you collaborate on the Linux kernel? Lukas: The team and I at KUNBUS work like all other developers in the open source project. For example, we make contributions for optimization or bug fixes, especially with regard to the Raspberry Pi. Because we have a focus on the industry, we have a special view unlike that ..read more

An essential part of our Revolution Pi development philosophy is to enable open source in industrial settings. This means not only providing an open platform, as exemplified by the Raspberry Pi, but also supporting the open source resources it contains. Product Owner Nicolai shares how he and his team anchor open source in the company and why we are also willing to show our hands when it comes to certain parts of our hardware. Why did KUNBUS decide to enter the industrial world with an open source operating system in 2016? Nicolai: Because the openness of open source was already the future in ..read more

A team of production staff, IT, and business development meets and shows how easy it is to install an HMI with Revolution Pi and Node-RED in our production. Our exemplary use case: the partial automation of our THT assembly. In addition to machine SMD assembly, larger parts must be attached to RevPis by hand (THT assembly). The advantage of this is that the components can be bonded to the PCB with sufficient strength. Which makes the RevPis particularly resistant to environmental stress. To simplify the manual process, the display of the assembly plans was automated – with a Revolution Pi Conn ..read more

Their knowledge is often based on decades of experience: Machine and plant operators are hard to replace – they hear and feel their machines. So, what can be done when there are no successors? One possibility is to imitate this know-how digitally. Here, Revolution Pis can support knowledge management without interfering with existing systems. Companies face that experienced employees are taking their accumulated knowledge into their well-deserved retirement. This loss weighs particularly heavily when machine and plant operators know their machines inside out. After all, if you know a plant lik ..read more

The showdown before each RevPi is shipped: the final test to see if a device will make it to the customer. With our specially manufactured End of Line testers (EOL-tester), each individual module is tested for flawless function – also by RevPis themselves. Each module family needs its own EOL-tester, because not all interfaces are the same across modules. Thus, there are separate testers for the base modules, the gateways as well as digital, analogue, and CON extension modules. Part of each setup is a permanently installed RevPi module: It tests the communication capability of the clamped modu ..read more

Use industrial applications with Microsoft Azure and profit from one of the big players: We are delighted to announce that our Revolution Pi base modules RevPi Core 3+ and RevPi Connect+ are now in the Microsoft Azure Certified Catalog. It’s a perfect match Collecting data is one of the RevPi’s strength. And Azure is widely used to create management and monitoring dashboards from machines and plants. Therefore, Revolution Pis are perfect to send data to the Azure cloud. Now, the certification shows officially that your RevPi-solutions will work smoothly in Azure. You can especially profit from ..read more

The Industry 4.0 era sees increased use of Linux based industrial PCs for automation systems, blurring the line between IT and OT (automation). Revolution Pi is an excellent example and that`s why CDP Studio pre-configured the RevPi range in their development platform (IDE), so customers can easily develop IT-based automation systems. CDP Studio is a software development tool for real-time distributed control systems. It’s goal is to bring the power and flexibility of C++ systems programming to the level where it is as simple and convenient to use as traditional OT software tools. CDP Studio a ..read more

Perfectly cooked food without stress while using the RevPi Core 3+? A team of barbecue-enthusiasts and budding technicians shows how this is possible within their semester project. In 1400 hours of work, they created a pellet smoker that fully takes over the cooking process. All the operator must do is to connect the appliance to the power supply, fill in the pellets and switch on the device. The type of meat and the desired cooking state are selected via the graphical user interface on a 16.5-inch touch screen. The operator chooses from 8 types and the cooking stages rare, medium and well. Sp ..read more

This article is not directly related to the RevPi. I wrote it as a by-product of the DMX article. Since I have done some research on dimming LEDs, I would like to share my current – probably incomplete – state of knowledge on the subject. What is the issue with dimming LEDs? LEDs are dimmed by PWM. This is not very complex and saves energy. The basic requirement is that the frequency is sufficiently high so that you no longer perceive flickering. But, you might run into EMC problems. This is simply due to the fact that a PWM is a square-wave signal. Therefore the signal contains a large propor ..read more
