Introduction: This is the hardware and source code for an Atmel ATmega48 based four digit Nixie Tube Clock. Description: This was my second Nixie clock project. I wanted something a little smaller / cheaper / simpler then my rather large B-7971 clock. I will post the design for that one of these days. I was …

Based on the Atmel ATtiny12L-4PI microcontroller -A real Time Clock/Calendar for less than US$1.50 in moderate quantity. This is the timekeeping test circuit. It includes a one-transistor circuit to switch in the 5V power supply when present and drop back to the 3v battery the rest of the time. That loop of blue wire-wrapping wire …
If your school, or kids school, or other location relies on a central master clock that is broken, you may have a use for this device. New master clocks are available of course, but school budgets are under extreme pressures, and it really is a satisfying project if you have the necessary skills. This master …

The great adventure that is building clocks continues. Points of interest in this build is that it was the first chance I got to play with the dot matrix display I picked up over winter break, and it’s the first time I’ve soldered and used a surface mount package (albeit I soldered it to a …
The Network Time Protocol (NTP) has revolutionized the world. Suddenly one could have anywhere in the world accurate time and date. NTP is a simple UDP based protocol and can be implemented in a Microcontroller. Using the tuxgraphics ethernet board and a LCD display we build a nice clock which gets time and date via …
Its a digial clock which make use of AT89C4051 to work as a Real time clock. Figure 1 shows the circuit diagram for the digital clock. Port 1 of the controller (AT89C4051) is used as the data lines for the LCD (starting from pin 7- pin14 of LCD). As you can see there is not …

Introduction The clock is one of the oldest inventions in human history and has been used for centuries as in instrument for measuring time. There are many ways to implement this ancient technology by simple and practical methods. However, simplicity and practicality were not among the goals of this project. Instead, the project is intended …

While exuding retro style, the alarm clock in its original state lacked many desirable features of today’s alarm clocks. The only controls consisted of a single on/off switch. It also lacked AM/PM indication, making it impossible to sleep for more than 12 hours. Our project sought to maintain the integrity of the original alarm clock, …
For our ECE 4760 final project, we designed and built a wirelessly programmable digital pace clock with a large format LED display and Android smartphone control and programming. This original design achieves the functionality of commercailly available pace clocks but with an intuitive user interface that goes beyond anything that is available in the current marketplace, all at a small fraction of the cost. The clock …

The goal of our project was to create a persistence-of-vision (POV) analog clock using an LED display. The clock has a visual alarm system which lights up the entire display for two seconds if it reaches an alarm time. The current time and alarm times are preset into the clock before it begins to spin. …
