EXPERIMENTAL NEXT-GENERATION CHIP-SCALE ATOMIC CLOCK

Physicists at the National Institute of Standards and Technology (NIST) and partners have demonstrated an experimental, next-generation atomic clock—ticking at high “optical” frequencies—that is much smaller than usual, made of just three small chips plus supporting electronics and optics. Described in Optica, the chip-scale clock is based on the vibrations, or “ticks,” of rubidium atoms confined in a tiny ...

Take a Break From Coding: How to Relax at Work

Employee burnout is becoming a more common problem than it once was. One study found that nearly a quarter of workers felt burned out often, or even always. To combat burnout, you need to learn how to relax at work. While it may be tempting to set a breakneck pace and push yourself every day, burnout will harm you in the long run. It can make you a less capable worker, diminishing your performance on the jo ...

A combined MSF/DCF atomic clock receiver

For this to work you must obviously live in an area that can receive both signals. My circuit is based on two modules taken from two radio clocks bought at Lidl’s supermarket. Originally both were for the DCF clock but by substituting the original 77.5kHz crystal with a 60kHz crystal, one of the modules was converted to MSF. Notice that both antennas are lined up in my photograph. This is because Anthorn an ...

How to Use PICKit3 to upload code to pic microcontroller

For programming PIC microcontrollers we require a piece of hardware that can communicate between the computer and the microcontroller known as a programmer. There are several programmers available out there but we will be using PICkit3 for this example due to its versatility. One important note before we start, is that if you plan on buying a PICkit3 programmer/debugger, make sure you buy it from Microchip ...
