postmarketOS Linux Mobile OS Supports Over 100 Devices

postmarketOS

postmarketOS is a Linux operating system that was first unveiled in 2017, with the developers aiming to provide long term support in order to extend the life of existing phones.  The operating system is based on Alpine Linux with touch-screen optimization, and the goal is to provide updates, including security updates, for at least 10 years just like you would get on a computer. The project was really getting started at the time, but now the community has provided an update for the first 600 days of development, and over 100 devices are now supported, mostly smartphones such as Google Pixel 3 XL or Motorola Droid 4, but also some SBCs, for instance, Pine A64-LTS and various Raspberry Pi boards. “Supported” means the 112 devices listed can boot postmarketOS, but the operating system is still considered to be alpha software, and for example, if you look at the features matrix in the list of the device, you’ll find only LG …

Minnow Server is a Secure Web Server for Microcontrollers

Minnow Server Secure Websocket

Many embedded systems have a limited amount of memory, which would normally run programs with smaller footprints than on desktops or servers. For example, nginx and Apache2 are the common web servers, but on hardware with limited memory, smaller footprint web servers may be required, so that’s why I wrote a list of web servers for embedded systems running Linux/uClinux many years ago. But now, even platforms based on microcontrollers often need to run web server usually for configuration. We’ve already shown how to use Arduino to serve a simple web page and did the same in Getting Started with NodeMCU Board Powered by ESP8266 WiSoC but using Lua programming language instead. It may be more convenient to run a proper web server however, as it’s easier to change the interface, and we previously covered MicroWebSrv lightweight web server that works on platforms running MicroPython such as Pycom boards. Real Time Logic offers another open source alternative with their Minnow Server …

PSLab Electronics Lab Board is Now Available for $65

PSLab Electronics Lab

Pocket Science Lab (PSLab) is an open source hardware USB board that aims to bring electronics labs to the masses, as it can act as an oscilloscope, voltmeter, programmable voltage and current source, logic analyzer, or signal generator when connected to a PC or mobile phone. This is not professional equipment, and instead designed for STEM education. When we first covered the board in August, it was still in development, but I’ve just found it is now listed and in stock on Seeed Studio for $64.90. FOSSASIA and OpnTec are the organization behind the board’s development. Here’s a reminder of PSLab board main specifications: MCU – Microchip PIC24EP256GP204 16-bit microcontroller @ up to 70 MHz with 32KB SRAM, 256KB flash Wireless Connectivity Footprint for ESP8266 module (ESP-12E) for 802.11 b/g/n WiFi (on bottom of board) Bluetooth extension slot 4-Channel, up to 2MSPS Oscilloscope 12-bit Voltmeter.
