Fresh hacks every day
We see plenty of clock projects come through, but usually it is their visual or mechanical design that stands out. The DCF-77 LED PIC clock is fun because it is synchronized with the Atomic clock in Braunschweig Germany. The clock picks up the radio signal at 77.5 KHz known as DCF77, and that’s where it got its name.
The circuit … Read the rest
What you see above is a master clock. It is the center of a system that can run an unlimited number of slave clocks, keeping them on-time thanks to its ability to synchronize with an atomic clock. [Brett Oliver] put together the project back in 2005 using digital logic chips, and no programmable microcontrollers. This includes everything from the binary … Read the rest
We hope you paid attention in advanced theoretical and quantum physics classes, or making your own Open Source Scanning-Tunneling Microscope might be a bit of a doozy. We’re not even going to try to begin to explain the device (honestly we slept through that course) beyond clarifying it is used for examining the molecular and atomic structure of surfaces; but … Read the rest
[Chris Kuethe] shows how to scavenge what could be a pricey WWVB module from a radio controlled clock. WWVB is a special radio station in Colorado that transmits an atomic-clock-derived signal to RC clocks. The clock model he uses, the Atomix 13131, goes for less than twenty bucks. He also shares the link to another tear down of a … Read the rest
As purveyors of a fine hacks, we often get pitched on what are generally considered very bad ideas. Luckily, most of these ideas die on the drawing board due to a lack of time and energy or maybe having a shred of moral accountability. There’s nothing that government funding can’t fix though. Popular Science has put together a gallery … Read the rest
