The device provides a single non-isolated output from 1 to 32 V at up to 3 A, with a maximum output power of about 92 W when supplied by a 100-W USB-C Power Delivery source. […]

Software is being released at a pace traditional testing approaches struggle to match, while AI is moving from assisting with test design to generating, adapting, and maintaining tests across the delivery pipeline. The question facing software testers is no longer only how to scale testing, but how to guarantee the evidence automation produces. In this environment, the […]

They are blaming DRAM and eMMC shortages, with nothing coming back before mid-2027. PINE64, the open hardware manufacturer, recently posted an update on its Mastodon account, and it’s not great news if you were hoping to grab new Linux-powered hardware. The disruptions in DRAM and eMMC supply are to blame, as PINE64 says its Linux […]

People have been popping up in various maker forums asking about Raspberry Pi Pico 2 boards and adding an Apple Lightning cable. The reasons: jailbreaking/bypassing iDevices with Apple A12/A13 CPUs using the usbliter8 boot ROM exploit by Paradigm Shift. One X user (stacksmashing) even replied: “I literally have this on my desk right now”. The […]

Johns Hopkins University researchers have developed a system to continuously monitor blood pressure without the need for arterial lines. Familiar blood pressure cuffs that wrap around the arm aren’t invasive, but they only provide intermittent readings. The team created a system called MOSAIC based on two sensors—one placed on a patient’s chest, and the other […]
