Most ski lifts are pretty simple systems: they use big ol’ motors to pull cables with chairs or hangers attached. More advanced detachable designs let the chairs come off the cable temporarily while in the terminal, so skiers can hop on at a leisurely pace. But basic fixed-grip chairlifts don’t have that capability and skiers have to jump on while the chairs move at full speed. To help ski lift operators space those chairs properly, Marc Antaya designed the Ski Lift Spacer 2000.

Antaya was working as a liftie at a local ski area and noticed that it was difficult to attach chairs to the ski lift cable at consistent intervals that facilitate smooth operation. So he built the Ski Lift Spacer 2000, which measures the cable speed and distance traveled, calculates the spacing, and stops the lift at the right times to hang the chairs. It is wired in series with the lift’s existing controls, so it can’t override their safety measures. It simply provides a remote start/stop function, which it can perform when desired for attaching chairs.

The device consists of an Arduino Nano Every board, lithium batteries, relays, an LCD screen, and a control interface. That interface is important, because it lets lifties calculate the chair positions in several different ways based on the data they have available. For example, they can start with a certain number of chairs and the cable length. In that case, the device will calculate the spacing between chairs. Or they can enter the cable length and desired spacing, in which case the device will calculate the total number of chairs required.

To do its job, the device needs to know exactly how much the cable moves. To achieve that, Antaya built a wheel turned by the cable. It has magnets, which the Arduino can use for rotational encoding thanks to Hall effect sensors. This is all configurable in the device menu system, where the liftie can set the wheel circumference/diameter and number of magnets.

Antaya has already tested an earlier version of the Ski Lift Space 2000 at his local ski area. After updating it as shown in the video, it is ready for a second round of testing.

In areas that experience plenty of cold weather, icicles and ice dams can present a very real danger to the people and property nearby. In response, Eivind Holt has developed a computer vision-based system that relies on an Arduino Portenta H7, a Portenta Vision Shield, and a slew of AI tools/models to recognize this ice buildup. Best of all, the board’s low power consumption and LoRaWAN connectivity means it can be deployed almost anywhere outdoors.

Before a model can be created, it needs copious amounts of training, data which normally comes from manually-annotated, real images. But recent advancements have allowed for synthetic datasets to be used instead, such as with NVIDIA’s Omniverse Replicator. It was in here that Holt programmatically added a virtual house and randomized icicle models, as well as configured Omniverse to move the camera around a raytraced scene in order to snap virtual pictures and annotate them with the correct label.

Once the realistic, synthetic data had been created, Holt exported everything to Edge Impulse and trained an object detection model for the Portenta H7, although it was also tested in NVIDIA’s Isaac Sim environment via the Edge Impulse extension prior to deployment. Alert generation was achieved by connecting the LoRaWAN radio to The Things Stack and sending a small, binary payload every ten seconds if any icicles were detected.

More information about this project can be found in its Edge Impulse write-up.

In the rapidly evolving landscape of industrial technology, three interesting trends are intertwining to streamline processes, improve efficiency, and reduce downtime. They are retrofitting, remote control/monitoring, and power metering – and together, they make for a great strategy to upgrade and improve existing machinery, reaping all the benefits of connected things and data analysis without the huge investment of completely new equipment.

• Retrofitting industrial machinery
  Retrofitting industrial machinery involves updating existing equipment with modern technology to enhance functionality and performance. It allows businesses to extend the lifespan of their machinery while adapting to evolving industry standards and requirements.

• Remote monitoring and control
  Remote monitoring and control enable businesses to oversee their operations from anywhere in the world. This capability not only improves operational efficiency but also facilitates proactive decision-making and troubleshooting, ultimately reducing costs and downtime.

• Power metering
  Power metering entails tracking and analyzing energy consumption. By monitoring power usage, businesses can identify areas for optimization, reduce waste, and lower energy costs, contributing to sustainability efforts and improving their own bottom line at the same time.

Our latest demo showcases the seamless integration of these three crucial aspects into a single solution, using Arduino technology.

The demo in detail

We focused on retrofitting an injection molding machine – a common piece of industrial equipment – with advanced automation capabilities. By replacing the original controller with the Arduino Opta WiFi micro PLC, we transformed the machine into a connected device.

Now, integrating with the Arduino Cloud, users can monitor and control the injection molding machine remotely via intuitive dashboards. This connectivity allows for real-time oversight of production cycles, performance metrics, and equipment status from anywhere with an Internet connection.

Additionally, the Arduino Opta WiFi is equipped with RS485 communication capabilities, enabling seamless integration with an external power meter – in our case, a Finder model. This provides valuable insights into energy consumption, production output, material usage, and equipment health.

The collected data is then analyzed through dedicated dashboards, offering information about operational efficiency and potential issues. By leveraging this data, businesses can proactively schedule maintenance and repairs, minimizing downtime and optimizing production processes.

Retrofitting for a connected future

Many businesses today can retrofit existing machinery to embrace the benefits of connectivity and automation. Our demo provides a practical example of how common industrial equipment can become smarter, more efficient, and easier to manage. From remote monitoring and control to power metering and predictive maintenance, retrofitting offers a sustainable way to modernize industrial infrastructure.

Unlocking potential across industries

Moreover, the versatility of Arduino’s open-source ecosystem ensures that this solution can be adapted and applied to a wide range of existing machines and equipment, enhancing their operation effectively – whether in manufacturing, logistics, or any other industry relying on machinery.
