Method of Make

A demonstration circulating online shows how solar cells can be produced using a standard microwave oven, an unconventional approach to a manufacturing process normally done in expensive industrial furnaces. The technique is drawing attention among engineers and clean-energy enthusiasts, who are debating whether simplified, low-cost methods like this could make photovoltaic production more accessible to hobbyists and small labs.

A new explanation of making solar panels using a microwave oven is drawing wide attention online, with hundreds of thousands of people engaging with the idea. The piece walks through how microwave heating can be used in processing the materials that go into photovoltaic cells, an unconventional twist on solar manufacturing that has sparked curiosity and debate about whether such low-cost methods could ever scale beyond the lab or hobbyist setting.

Researchers at Binghamton University say imperceptible audio trigger words could be used to manipulate AI-powered robots into unsafe behaviour, effectively hijacking their actions without operators noticing. The team has also developed a defensive method to detect and block such attacks. The work highlights growing security risks as robots with large language models are deployed in homes and workplaces.

A new method has been presented for detecting tampering with AI model weights directly in GPU memory, targeting so-called Rome attacks. The approach aims to catch attackers who modify a model's parameters while it is loaded in memory, a scenario where tampering would otherwise go unnoticed. The technique is drawing attention from AI security researchers and practitioners concerned with supply chain and runtime integrity of deployed models.

Researchers at Chalmers University of Technology in Sweden have outlined a method for coordinating large fleets of self-driving electric taxis, addressing how thousands of autonomous vehicles could be managed together as a shared transport system. The work targets the operational challenge of orchestrating driverless electric fleets at scale, a key step toward making robotaxi services practical in cities.

A German-language discussion is underway about basic authentication and when it might still make sense. The argument: for portals where use is time-critical and operators trust their user base, a simpler auth mechanism could be preferable. Foodsharing, a food-rescue platform, is cited as a possible candidate, with the comment touching on PHP and remote code execution concerns.

Researchers report that using a stiffer coupling between a human operator and a bimanual robot makes the teaching process faster, allowing demonstrations to be given more quickly. However, the stiffer setup did not improve how accurately the robot reproduced placement tasks. The finding suggests trade-offs for anyone designing physical human-robot teaching interfaces, where speed of instruction can be gained without any gain in task precision.
