Introduction Even in a digital world, classic analog clocks have a timeless style. This simple but universal technology is presented in the article. The implemented project uses a dual-rail GreenPAK™ SLG46121 which can perform all the active electronic functions needed in an...

This project is a clock with radio receivers that can receive the exact time from the GPS satellites or from the DCF77 transmitter. by hkdcsf @ hackaday.io This project is a clock with radio receivers which can receive the exact date and time from the DCF77 time signal transmitter or...

Most microcontroller implementation these days, use the traditional capacitor + crystal approach to generate their clock, this approach sometimes, however, lead to problems, especially when used in prototyping situations with a breadboard, jumper wires, etc., all of which have an...

As demand grows, precision and reliability in Global Navigation Satellite Systems (GNSS) is critical. With 5G networks on the rise, small, high-performing atomic clocks are becoming increasingly essential. Suntsu’s newest oscillator comes in a dimension of 50.8mm x 50.8mm that uses an...

This is a minimal and small clock based on PIC16F628A microcontroller and DS1307 RTC IC. It is able to only show the time on a small 7-segment display with a total of 4 segments. The display we used is a 0.28″ SR440281N RED common cathode display bought from LCSC.com, but you can use...

Replace over-air time by Internet time About twenty years ago I recycled and modernised a vintage clock with Nixie tubes built by my father in the nineteen seventies. I replaced the digital logic by a microcontroller and used a DCF77 receiver module instead of the original 50-Hz...

Driving multiple loads from a single oscillator output discussed in this app note from SiTime. Optimizing board space and managing power consumption of wearable devices is critical in sustaining competitiveness within this fast growing consumer segment. With less power consumed,...

The NIXLER is being built as an open-source project and designed with the DIYer in mind. I've included a USB to UART chip directly on the board making the NIXLER easy to reprogram. This together with the onboard ESP32 microcontroller with wifi/bluetooth, enables full customization. Hook...
