• CNX Software ☛ Macintosh emulator works on ESP32-P4 display devkits from M5Stack and Waveshare

  ESP32 chips have been used for retro gaming and computing for years, but Austin McChord (Amcchord) adds to that with a Macintosh emulator ported to a couple of ESP32-P4 display devkits. His project is a full port of the BasiliskII Macintosh 68k emulator, bringing classic Mac OS (System 7.x through Mac OS 8.1) to portable ESP32-P4 embedded devices with touchscreen, USB peripherals, and WiFi support through an ESP32-C6 on the boards.

• Nicolas Fränkel ☛ Two nasty surprises in Home Assistant's config

  Last year, I motorized the rolling shutters on the southern façade of my apartment. My idea was to manage them via Home Assistant. I had a couple of automations in mind: In the evening, roll down the shutters of my bedroomIn the morning:If it’s too hot outside, roll down all shuttersIf it’s too cold outside, roll down all shuttersIn other cases, roll up all shutters but my bedroom’s Living in France, I added the official Météo France integration.

• ROS Industrial ☛ ros2_canopen: Natively Integrating CANopen Devices into the ROS 2 Ecosystem

  CANopen has long been one of the most widely used communication standards in industrial automation. Built on top of the CAN bus and standardised by CAN in Automation (CiA), it connects motor drives, I/O modules, sensors and other field devices across machines, robots and vehicles. The ros2_canopen stack, maintained under the ROS-Industrial umbrella, brings this ecosystem natively into ROS 2. It lets developers describe a CAN bus, bring up a CANopen master, and talk to every device on the bus through standard ROS 2 nodes, services, topics and ros2_control interfaces.

  • Chuck Carroll ☛ Installing OPNsense

    So there we have it, an open source FreeBSD-based firewall and router on this appliance. I had made a small attempt to get a RHEL-based distro to run, but getting everything configured properly is surprisingly difficult to do without a display. This is something I'm still tinkering with.

    I've also read that using a different SSD other than the original will trigger a "no boot drive" error.

  • Josh Lospinoso ☛ The Badge That Would Not Become Small

    There is a badge on my phone right now, red and ordinary, sitting on top of an app whose whole job is to keep me from trusting my own memory too much.

    I pick up the phone for something else. That is how these objects get me. I am not opening the task. I am looking for a confirmation code, the name of a portal, the message with the link, the one little door I have already turned into a private ordeal, and there it is again: the number, bright enough to interrupt me and too small to respect.
