Breathalyzer Firm Outage Halts Calibrations, Stranding Drivers

A cyberattack on Intoxalock disrupted its breathalyzer calibration services, leaving drivers unable to calibrate their devices and stranded; the company is offering 10‑day calibration extensions and occasional towing, with no disclosed data breach. The WIRED security roundup also covers the FBI resuming purchases of commercial location data, an Iranian-linked hack disrupting Maryland hospitals’ Stryker medical devices, an AI agent security incident at Meta, and the takedown of several botnets used in major cyberattacks.

DIY Nuclear Event Detector Recreated, Seeks Gamma Calibration Help

Hackaday covers Bigcrimping’s BHG-2000, a pin‑compatible DIY replacement for the now unobtainable HSN‑1000 nuclear event detector. The build uses four BPW34S PIN diodes coated to block visible light, aiming to detect the characteristic gamma pulse that signifies a nuclear event, with a two‑stage amp chain to output a warning. Calibration remains unverified without exposure to gamma sources, and the creator is seeking European testers with Cs‑137 or Co‑60 sources. The project is open‑source, and Hackaday cautions that nuclear explosions are best avoided while noting the detector concept could in principle warn of blasts.

NASA’s Perseverance Rover Continues Exploring a Tiny Maze on Mars

NASA's Perseverance rover is repeatedly photographing a tiny, intricate maze on a metallic calibration plate on Mars, which is part of the SHERLOC instrument used to search for signs of ancient life. The maze helps calibrate the rover's laser and imaging systems with high precision, and the plate also tests materials for future human missions, blending scientific purpose with hidden storytelling elements.

NASA's Perseverance Rover Focuses on Mars' Mysterious Maze

NASA's Perseverance rover repeatedly photographs a maze on its SHERLOC calibration target, which is used to calibrate its spectroscopic instruments for detecting organic compounds and minerals on Mars. The maze, made of chrome lines on silica glass, helps ensure precise laser focus and positioning, and features a Sherlock Holmes portrait as a fun nod and functional marker. The calibration target also includes materials for testing spacesuit durability and supporting science for future human exploration.

"Overwatch 2 Player Surprised by Massive Rank Improvement Without Playing Main Role"

In Overwatch 2, a player was surprised to receive a significant rank progress despite not playing their main role in Competitive mode. The game's latest rank changes include a "soft reset" to players' MMR, leading to adjustments based on performance. The player's confusion was addressed in a Reddit thread, with some users explaining that the game's modifier "Calibration" is responsible for the unexpected rank progress when playing a different role, as it assesses uncertainty and aims to determine the player's true rank.

Enhancing the CH32V003 MCU with Temperature Sensor Capability

A low-cost CH32V003 MCU, lacking temperature measurement functionality, can be improvised to include a temperature sensor by measuring the drift between two internal clocks and using it to calibrate a temperature graph. By utilizing the automatic wake-up unit (AWU) and accessing the LSI clock source indirectly, a temperature plot was obtained, although the absolute accuracy of this method may vary per MCU. This crude temperature measurement solution could be sufficient for basic applications.

"ESA Develops Artificial Star for Groundbreaking Research"

The European Space Agency (ESA) has developed an artificial star-like light source to test the optical performance of startrackers, which are used by spacecraft to determine their position in space. The test bench, located at ESA's ESTEC technical centre in the Netherlands, combines a rotating table with a single star simulator to simulate the light from a star. The purpose of this facility is to calibrate startrackers in terms of distortion, chromatic aberration, and other optical variables, aiding in spacecraft navigation.
