Pi 5 overclocking: Silicon Lottery
Silicon lottery. Now that the Raspberry Pi 5s been readily available (at least in most regions) for a few months, more people started messing with clocks, trying to get the most speed possible out of their Pi 5s. Unlike the Pi 4, the Pi 5 is typically comfortable at 2.6 or even 2.8 GHz, and some Pi 5s can hit 3.0 GHz…

Battery-free self-powered sensor harvests magnetic energy
MIT researchers designed a self-powering, battery-free, energy-harvesting sensor. Using the framework they developed, they produced a temperature sensor that can harvest and store the energy from the magnetic field that exists in the open air around a wire.
