So I made this project for my dad for Fathers Day a couple of years ago, and thought i'd share it. The one shown is the Rev-1 design which is far from perfect, in fact it has several major issues I will discuss below, however it definitely works,

WarGames Clock

If you haven't seen the WarGames movie, do yourself a favour and go watch it right now. If you have, then you know just how awesome it is. One part, as a kid, I always thought was awesome was the WOPR computer. A key scene in the WarGames

Nokia 5110 - Back from the dead. Part 1: Nostalgia

I loved my Nokia 5110 and I wonder if it was possible to breathe new life into this long-shelved and still-memed mobile phone. As it turns out, not only is it possible, but it's going to be a lot easier than I anticipated.

WiFi Binary Clock

Who doesn't love a classic Binary Clock? I remember getting one of these when I was in my 20's from ThinkGeek, and it was pride of place on my desk. LED's are a thing of beauty.

IBM M13 Trackpoint USB Converter

Me, never not on the lookout for an opportunity to design something, whether needed or not, worked with @micon to design a module that could fit snugly in the keyboard, and provide a USB-C interface directly into the Keyboard/Mouse module.

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.

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.

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.
