CNX Software ☛ upyOS modular MicroPython-based OS for microcontrollers works with ESP32, RP2040, etc…
upyOS is a modular, lightweight MicroPython-based operating system (OS) that provides a Unix-like experience on low-resource microcontrollers such as Espressif Systems ESP32/ESP32-C3/ESP32-S3, Raspberry Pi RP2040, and others. Inspired by smolOS, upyOS offers remote development tools, OTA updates, and a built-in web server. Its modular architecture separates system functions into reusable components, instead of large, monolithic programs.

Hackaday ☛ The Entire Process Of Building An Open Source Analog ASIC
Our hacker [Pat Deegan] of Psychogenic Technologies shows us the entire process of designing an analog ASIC. An ASIC is of course an Application-Specific Integrated Circuit, which is basically just custom hardware. That’s right, “just” custom hardware.

Arduino ☛ SoilTile turns earth into an oversized touchpad
This works in a manner similar to conventional pressure-sensing mats, with cathodes and anodes separated by a compressible medium. In this case, that medium is soil. The top “cover” can be anything from real grass turf to a comfy toe-pleasing shag rug. The prototype SoilTile has four cathodes to create a 2×2 grid of pressure sensors and several tiles can be positioned adjacent to each other to produce larger arrays.
An Arduino Mega 2560 board monitors the cathodes through analog pins and their reported voltages correspond to pressure. When weight increases on a cathode, it compresses the underlying soil and gets closer to the anode. That lowers resistance and increases voltage. It isn’t precise or accurate, but it is good enough for a wide range of applications.
