  • Arduino MKR IoT Carrier embeds display, sensors, and I/Os for IoT projects

    Arduino Oplà IoT Kit was launched last fall as the first open programmable IoT platform from the company. The kit included everything you need to create your own IoT devices with MKR IoT carrier with a 1.3-inch OLED color display, environmental sensors, capacitive touch buttons, Arduino MKR WiFi 1010 board, external PIR motion and moisture sensors, a circular plastic enclosure, and various cables.

  • Open-spec Raspberry Pi CM4 carrier has M.2 and GbE with PoE

    Oratek’s $110 “Tofu” carrier for the RPi CM4 is equipped with GbE with PoE, HDMI, 3x USB, Type-C, MIPI DSI- and CSI, 7.5-28VDC input, and M.2 with micro-SIM and NVMe support.

    The Oct. 2020 launch of the Raspberry Pi Compute Module 4, which lacks pin compatibility with the RPi CM3, has attracted a new wave of companies selling carrier board alternatives to the official $35 carrier. The latest is Switzerland based Oratek, which has opened pre-orders for a Tofu board for 99 Swiss Francs (about $110), with shipments due in mid-March. The board ships with schematics, mechanical drawings, a STEP file, and other open hardware resources.

  • Now you can run Unix on the tiny $4 Raspberry Pi Pico | ZDNet

    Developers who have one of Raspberry Pi's latest gadgets, the Pi Pico, have a newly ported potential operating system to work with called Fuzix, a Unix-like OS for small things.

    "So you can now run Unix on a $4 microcontroller," said Raspberry Pi in its blog post about the project.

How I digitized my CD collection with open source tools

The restrictions on getting out and about during the pandemic occasionally remind me that time is slipping by—although some days, "slipping" doesn't quite feel like the right word. But it also reminds me there are more than a few tasks around the house that can be great for restoring the sense of accomplishment that so many of us have missed. One such task, in my home anyway, is converting our CD collection to FLAC and storing the files on our music server's hard drive. Considering we don't have a huge collection (at least, by some people's standards), I'm surprised we still have so many CDs awaiting conversion—even excluding all the ones that fail to impress and therefore don't merit the effort.

Hyperbola Linux Review: Systemd-Free Arch With Linux-libre Kernel

In the last month of 2019, the Hyperbola project took a major decision of ditching Linux in favor of OpenBSD. We also had a chat with Hyperbola co-founder Andre Silva, who detailed the reason for dropping Hyperbola OS and starting a new HyperbolaBSD. HyperbolaBSD is still under development and its alpha release will be ready by September 2021 for initial testing. The current Hyperbola GNU/Linux-libre v0.3.1 Milky Way will be supported until the legacy Linux-libre kernel reaches the end of life in 2022. I thought of giving it a try before it goes away and switches to BSD completely. Read more
