=> ↺ Arduglasses - Hackster.io
The glasses are made out of printed circuit boards from OSH Park. The electronics driving the two displays are entirely on the right side stem of the glasses along with a small 100mAh rechargeable battery that will run the glasses for a little more than an hour. The left side stem is the same PCB, just unpopulated.

=> ↺ BlueSCSI v2 Pico announced for retrocomputing storage
BlueSCSI is an open source, open hardware, and open design SCSI solution for vintage computers.
The original version 1.x devices use a “Blue Pill” microcontroller board based on ST chips. Due to the chip shortages, clone ST chips have often been used.
=> ↺ A tiny “AT” (modem/communications) command parser
The AT/Hayes communications command set has been in use since the Hayes 300 modem in 1981. It’s a set of commands sent to a controller, setting parameters for communications. Being ubiquitous, it helps not to have to learn yet another set of commands for a new piece of hardware.
=> ↺ Harlow College students build CubeSats using Raspberry Pi Pico
The CubeSat platform is based around the Raspberry Pi Pico, consisting of three parts to the design: an acquisition board loaded with a camera and various sensors and storage; a master controller board with a radio link; and a ground station containing a radio link and decoder software. All three boards use the Raspberry Pi Pico, and the software is written with a mix of MicroPython and CircuitPython across the three boards.
=> ↺ A secure LoRa Mesh communications network
Thomas has built a secure communications network leveraging the plug-and-play qualities of the Raspberry Pi 4 and the Adafruit LoRa Radio Bonnet. It is the software side of this system that really turns these parts into something useful.
