Dave Darko designs a 16-button keep-alive switch with a Nano Every
It’s generally not advisable to leave equipment running when unattended. As a safeguard against this possibility at hackerspaces and elsewhere, element14 Presents’ Dave Darko built a custom switch that requires users to intermittently push a button in order to produce additional ‘on’ time.
The trick here is that instead of having one keep-alive button, the unit has a matrix of 16 buttons that light up randomly to be pressed. The idea is to prevent someone from setting up a second device to simply poke the same key over and over.
The ‘unhackable’ switch, which resembles a MIDI sequencer input, runs on an Arduino Nano Every and uses a relay to directly control the power state. It’s demonstrated toward the end of the video below, where Darko plays a sort of simple button-based game to keep an LED fixture on.

UP Xtreme Lite SBC offers more affordable Whiskey Lake option
Aaeon announced a slightly scaled down “UP Xtreme Lite” variant of its 8th Gen U-series based UP Xtreme SBC that provides up to 16GB DDR4, 2x GbE, 4x USB 3.2, and 3x M.2 plus SATA, HDMI, DP, and 40-pin GPIO.
Aaeon announced a Linux-ready UP Xtreme Lite version of its Kickstarter-backed UP Xtreme SBC, which has also been featured as the mainboard for Aaeon’s UPX Edge embedded system. Aaeon claims the UP Xtreme Lite will be more affordable than the original. Yet, this is the first UP board announced without individual pricing or any promises of community support from its UP project. It is possible that both will be forthcoming.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
