The article criticizes the inaccuracies of AI-generated electronic circuit designs, highlighting a flawed example where a diode is rated at 10 nanofarads, which is nonsensical. It emphasizes that current large language models lack true understanding and can produce misleading or incorrect information, drawing a parallel to past tech failures like the Intel Pentium FDIV bug, and warns about the risks of relying on such flawed AI outputs.
[mitxela] has created a tiny volumetric "electric candle" display using the persistence of vision concept. The display, made from salvaged parts including a motor from a CD drive, features an 8x10 array of surface-mount LEDs controlled by an RP2040 microcontroller. The project also includes a 3D-printed holder for a sensor and explores generating volumetric data and fluid dynamics calculations for a realistic flame effect.
Researchers at the University of California, Riverside have developed a new imaging technique to visualize the flow of electrons around sharp bends in nanoscale devices, similar to how air flows around airplane wings. By designing an "electrofoil" device, the team was able to contort, compress, and expand the streamlines of electric currents, allowing for the measurement of heat generated by electron flow. This research has the potential to improve the design of integrated circuits and optoelectronic devices by identifying areas where heat may cause damage and suggesting the use of gradually curved wires instead of sharp bends.
The Nashville Grand Prix will continue beyond 2023 with a new layout, despite the construction of a new NFL stadium that will impact the current location. The event's CEO, Jason Rittenberry, has confirmed that a new three-year extension with IndyCar is being signed, and the city is backing the promotion team to reimagine the layout in 2024 and beyond. The process of mapping out alternate courses has already begun, and will continue until the next design is finalized and approved by the city and series.
