We’re seeing a substantial turn towards online social interaction replacing in-person social interaction — especially among the younger generations. That was exacerbated and accelerated by the COVID-19 pandemic. But mountains of research show that physical touch is critical to a person’s mental wellbeing and online interactions haven’t been able to provide that. One solution may […] The post Could these VR haptic gloves replace human touch? appeared first on Arduino Blog.

A robotic hand with the dexterity to sign the whole ASL alphabet

Even if we ignore intelligence, humans are able to speak when other animals — even other great apes — can’t, because of our specialized and complex vocal anatomy. Similarly, ASL (American Sign Language) wouldn’t be possible without our incredible hand and finger dexterity. Like any other complex physiological system, that is difficult to recreate artificially. […] The post A robotic hand with the dexterity to sign the whole ASL alphabet appeared first on Arduino Blog.

Updated Arduino cores with ZephyrOS (beta)  

Last December we released our beta Arduino cores based on Zephyr. Today, we are excited to make another step in this beta program for Arduino cores based on Zephyr! ZephyrOS is an open-source, state-of-the-art, real-time operating system (RTOS) designed for low-power, resource-constrained devices. We are transitioning Arduino cores to ZephyrOS to ensure continued support and […] The post Updated Arduino cores with ZephyrOS (beta)   appeared first on Arduino Blog.

Is your heating radiator working? This system uses edge AI to find out

Heating isn’t just about comfort in very cold regions in the world, it is absolutely critical. If your home’s heat fails when you’re away, you might get back to find burst pipes. That’s especially problematic for large apartment buildings that rely on central boilers and radiators in the units. Manivannan’s Arduino-based edge solution leverages AI […] The post Is your heating radiator working? This system uses edge AI to find out appeared first on Arduino Blog.

This inexpensive adapter brings Apple Universal Control to vintage Macs

In the distant past of about two decades ago, one would need to use a KVM (Keyboard, Video, Mouse) switch to control multiple computers with the same mouse and keyboard — and even then, it would take a button press to move from one to the other. Today, Apple’s Universal Control feature lets users seamlessly […] The post This inexpensive adapter brings Apple Universal Control to vintage Macs appeared first on Arduino Blog.

How to run Uptime Kuma in Docker in an IPv6-only environment

I use Uptime Kuma to check the availability of a few services that I run, with the most important one being my blog. It’s really nice. Today I wanted to set it up on a different machine to help troubleshoot and confirm some latency issues that I’ve observed, and for that purpose I picked the cheapest ARM-based Hetzner Cloud VM hosted in Helsinki, Finland. Hetzner provides a public IPv6 address for free, but you have to pay extra for an IPv4 address. I didn’t want to do that out of principle, so I went ahead and copied my Docker Compose definition over to the new server. For some reason, Uptime Kuma would start up on the new IPv6-only VM, but it was unsuccessful in making requests to my services, which support both IPv4 and IPv6. The requests would time out and show up as “Pending” in the UI, and the service logs complained about not being able to deliver e-mails about the failures. I confirmed IPv6 connectivity within the container by running docker exec -it uptime-kuma bash and running a few curl and ping commands with IPv6 flags, had no issues with those. When I added a public IPv4 address to the container, everything started working again. I fixed the issue by explicitly disabling the IPv4 network in the Docker Compose service definition, and that did the trick, Uptime Kuma made successful requests towards my services. It seems that the service defaults to IPv4 due to the internal Docker network giving it an IPv4 network to work with, and that causes issues when your machine doesn’t have any IPv4 network or public IPv4 address associated with it. Here’s an example Docker Compose file: name: uptime-kuma services: uptime-kuma: container_name: uptime-kuma networks: - uptime-kuma ports: - 3001:3001" volumes: - /path/to/your/storage:/app/data image: docker.io/louislam/uptime-kuma restart: always networks: uptime-kuma: enable_ipv6: true enable_ipv4: false That’s it! If you’re interested in different ways to set up IPv6 networking in Docker, check out this overview that I wrote a while ago.
