Hackaday ☛ ESP32 Powers Custom Darkroom Timer
Developing your own film is an unabashedly analog process, which is one of the reasons people still gravitate towards it. After spending all day pushing buttons and looking at digital displays, spending some quiet time in the dark with pieces of paper and chemicals can be a way to decompress. But that doesn’t mean there isn’t room for a bit of modern digital convenience.

Arduino ☛ Easily build an energy meter with the Arduino Nano Matter
The Nano Matter is based on the powerful Silicon Labs MGM240S, which has an Arm Cortex-M33 processor and support for a number of wireless connectivity options, including 802.15.4 (Zigbee and Thread), Bluetooth® Low Energy 5.3, Bluetooth® Mesh, and Matter. That makes the Nano Matter perfect for smart home and other Internet of Things applications. To demonstrate that, Mr Innovative created an energy meter that would be useful to many people around the world.

Tom's Hardware ☛ Linux takes 4.76 days to boot on an ancient Intel 4004 CPU — CPU precedes the OS by 20 years
Programmer and hardware enthusiast Dmitry Grinberg has shared a video in which he boots and runs commands on an Intel 4004-powered PC running Linux. The video demonstrates the excruciating time to do anything or execute the most straightforward commands. Booting took 4.76 days, for example, and a simple directory listing didn’t hit the screen until 16 hours after inputting the ‘ls’ command.

Arduino ☛ Venderoo is an Arduino Mega-powered DIY vending machine
Constructing Venderoo started with a sketch that featured the dimensions, vending mechanism, and the electronics panel on the left. Then through a combination of a CNC router and a jigsaw, Grayson meticulously cut out each plywood panel and assembled them together along with clear acrylic sheets so students could observe the machine in-action. On the electronics side, an Arduino Mega 2560 is responsible for handling selections on the keypad, displaying commands/feedback to users via the character LCD, accepting money, and rotating the motors when it’s time to dispense.
