7-segment Mini Clock using PIC16F628A and DS1307 RTC
https://www.electronics-lab.com/7-segment-mini-clock-using-pic16f628a-ds1307-rtc/
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 other displays […]
Elektor Article: DCF77 Emulator with ESP8266
https://www.electronics-lab.com/elektor-article-dcf77-emulator-esp8266/
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 derived timebase. Over many years the clock has […]
Vintage VQB 71 Seven-Segment LED Displays Make GPS Clock Both Brilliant and Attractive.
https://www.electronics-lab.com/vintage-vqb-71-seven-segment-led-displays-make-gps-clock-brilliant-attractive/
Stephen Holdaway recently announced his project, a beautiful vintage VQB71 7-segment display based GPS Clock. Inspired by the fantastic appearance of the LEDs, Holdaway explains that the clock was built with a handful of vintage VQB 71 seven-segment LED displays and an u-box NEO-6M GPS module. “There are only so many applications for a 7-segment […]
Big digit 7-segment Clock using ATtiny3216
https://www.electronics-lab.com/big-digit-7-segment-clock-using-attiny3216/
This is a giant digital clock, featuring four large LED displays that provide the time in a format you can read from the other side of the room. by David Johnson-Davies: This clock was inspired by some 2.3″ one-digit 7-segment displays I saw on AliExpress [1]. I decided it would be fun to have a […]
Inside the digital clock from a Soyuz spacecraft
https://www.electronics-lab.com/inside-digital-clock-soyuz-spacecraft/
Ken Shirriff published an interesting article on his blog. He writes: We recently obtained a clock that flew on a Soyuz space mission.1 The clock, manufactured in 1984, contains over 100 integrated circuits on ten circuit boards. Why is the clock so complicated? In this blog post, I examine the clock’s circuitry and explain why […]
Network Clock using ESP8266 and OLED display
https://www.electronics-lab.com/network-clock-using-esp8266-oled-display/
There are several situations where using an RTC could adversely affect your project by increasing cost, size, time accuracy or IO requirements. To prevent this, especially in ESP/WiFi-based or other clock-reliant projects, makers usually turn to obtain time information from NTP servers. I recently came across a project by BitsandBlobs which used standalone NTP Servers […]
Arduino IN-14 Nixie Clock with a DS1307 RTC
https://www.electronics-lab.com/arduino-14-nixie-clock-ds1307-rtc/
GreatScottLab @ instructables.com shows us how to build an Arduino Nano based Nixie clock that features DS1307 RTC clock and 4x IN-14 Nixie tubes. He writes: In this project I will show you how to create a retro nixie clock. That means I will show you how you can control nixie tubes with a high […]
Arduino Wristwatch
https://www.electronics-lab.com/arduino-wristwatch/
This simple digital watch is inspired by the Eiriks Binary Wrist Watch from Sverd Industries! Check it out if you didn’t already. by Marijo Blažević Watch uses the same microcontroller as one on Arduino UNO – super hackable and easy to use! In this tutorial, I’ll be showing how you can make your own programmable […]
GPS Clock using uLisp
https://www.electronics-lab.com/gps-clock-using-ulisp/
David Johnson-Davies writes about his experiments with interfacing a low-cost serial GPS module directly to uLisp, to create projects such as a GPS clock. He writes: I’ll also describe a GPS speedometer and odometer, and a simple navigator, in later posts. The module I used is the GP-20U7, a small GPS module available for under […]
Arduino Clock on IN-18 Nixie Tubes with a LONG Service Life
https://www.electronics-lab.com/arduino-clock-18-nixie-tubes-long-service-life/
Build your own Nixie tube clock/thermometer/display with ease. by Grisha Anofriev @ www.hackster.io We set out to create a Nixie clock or just an information indicator on the largest ex-Soviet IN-18 tubes as an Arduino shield-compatible with both Uno and Mega boards. After a long reading of lots of information about IN-18 tubes on the […]
