• Adafruit Editorial Standards

  tl;dr: Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. This document is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community.

• ESP32-SBC-FabGL How to work with the expander module I2C from FabGL library and apps

  In this post I will show you how you can work with the I2C from the PC Emulator application and read Nunchuk position and buttons QBASIC and TURBO PASCAL 7.0

• Desktop steel marbles mood lamp

  This build falls firmly into the category of “I don’t know what it is or why I want it but I need it.” Twiddle the steel marbles (sounds nicer than “ball bearings”), and curate your own desktop disco according to your mood.

• My Commodore 16 keyboard is fixed!

  The replacement stem arrived, so over the weekend I set about finally fixing this keyboard. The VIC-20, C64, and C16 all share the same keyboard mechanisms, despite having subtly different layouts. This is very fortunate for C16 owners, as those other machines sold in huge quantities. Sourcing replacement parts for the Plus/4 and C128 are much more difficult.

• Fanless Thin Client supports 4x DP...

  Radeus Labs launched today a fanless Thin Client based on a low-power processor from the AMD Ryzen Embedded V1000 Series. Additionally, the device offers dual Gigabit ports and it can also be configured with multiple operating systems including Redhat, Ubuntu, Windows among others. 

• Do more with Vulcanexus snaps; your all-in-one ROS 2 toolset

  A surprise is awaiting all ROS developers in the Snap Store with the release of the Vulcanexus tool kit. They are one command away from getting eProsimas’ new contribution to the robotics community. From monitoring the performance of ROS 2 networks to integrating microcontrollers into ROS 2, Vulcanexus snaps offer developers easy and personalised development of robotic applications. 

• Open-Source Firmware For Soldering Irons

  For most of us, the first soldering iron we pick up to start working on electronics has essentially no features at all. Being little more than resistive heaters plugged straight into the wall with perhaps a changeable tip, there’s not really even a need for a power switch. But doing anything more specialized than through-hole PCB construction often requires a soldering iron with a little more finesse, though. Plenty of “smart” soldering irons are available for specialized soldering needs now, and some are supported by the open-source IronOS as well.

• Get MOST Into Your Pi

  When looking the modify a passenger vehicle, the Controller Area Network (CAN) bus is a pretty easy target. In modern vehicles it has access to most of the on-board systems — everything from the climate control to the instrument cluster and often even the throttle, braking, and steering systems. With as versatile as the CAN bus is, though, it’s not the right tool for every job. There’s also the Media Oriented Systems Transport (MOST) bus which is increasingly found in automotive systems to handle multimedia such as streaming music to the stereo. To access that system you’ll need to approach it slightly differently as [Rhys] demonstrates.
