A hobbyist salvaged vacuum fluorescent display (VFD) tubes from an old calculator and built a custom clock. The project involved reverse-engineering the tube pinout, designing a multiplexed driver circuit with a MOSFET and microcontroller, and using a 32.768 kHz crystal for accurate timekeeping. The finished clock was mounted in a CNC-milled wooden enclosure.
Researchers have restored and digitized previously lost images from the 1945 Trinity nuclear test, the first detonation of an atomic bomb. The newly recovered footage provides clearer and more detailed views of the historic explosion and its aftermath.
The article describes a redesigned voltmeter clock that uses analog panel meters as a visual display for time. The author details the build process, components used, and improvements over previous versions, focusing on achieving a cleaner and more polished aesthetic while maintaining accurate timekeeping.
A computational restoration project uses conservation research to digitally reconstruct famous paintings, aiming to reveal their original appearance based on scientific analysis and historical data.
A project details the construction of a custom clock using vacuum fluorescent displays (VFDs) salvaged from old electronics. The build involves designing a driver circuit, microcontroller integration, and a custom enclosure to create a functioning retro-style timepiece.
