Want to get up before the sunrise? Here’s the money shredding alarm clock project by Rich Olson’s to help you get yourself up early: If you have trouble getting out of bed a bed shaker alarm might be a bit extreme, you might … Read more
John Boxall over at Tronixstuff posted a step by step guide of his Clock four build: Next in my random clock collection is this model, which displays the time in words using a Freetronics DMD via an Arduino-compatible board.
Tully wrote to us about his latest project, the Arduino doomsday clock shield. The board features six 7-segment displays counting down up to the end of the Mayan calendar. Hey Ian, I want to show off one of my recent … Read more
jokkebk from Code and Life wrote this short how-to on interfacing the Bus Pirate to communicate with the DS1307 realtime clock. A good description showing beginners how to connect a BP to components or breakout boards and establish communications quickly … Read more
Community at it’s best, one forum member helping another. Matseng sent a Rino3 clock PCB to Arup, which he populated even before the Matseng got a chance to build his own. They are now debugging it together: Few days ago … Read more
Looking for something cooler than the typical nixie project? How about a nixie project done entirely in free form, no PCB style. Matseng designed this nixie clock around a single IN-1 nixie tube. It periodically reads out the time, digit … Read more
Here is another open source Nixie clock. It’s built with 3 boards stacked on top of each other. One for the high voltage power-supply, one for the control, and one to hold the nixies in place. Uses an Atmega328P microcontroller … Read more
Trax designed and built this word clock with capacitive sense buttons (machine translation). Hours and minutes are displayed as text instead of the typical numeric representation. The firmware also has an alternate option that turns the entire clock into a … Read more
Chankster built a Nixie clock that uses the NTP protocol to set the time over an internet connection. For a final touch, it was encased in concrete. Time is synchronized using the network time protocol. An ATmega keeps the time, … Read more
Easton Elliott made this 4000-series CMOS 24-hour clock as a final high school electronics class project. Rather than using a MCU he chose to use CMOS IC’s including a 4060 and 4013 to generate the 1Hz signal. The writeup and … Read more
An Arduino-based clock with 180 RGB LEDs. The LEDs are driven via 12 TLC5925 1- channel constant-current addressable drivers. Its built on doublesided copper clad board using Toner transfer method. The routes aren’t smaller than 0.44mm and all vias are … Read more
The Binary Burst clock shows the time with LEDs: The clock uses 3 LEDs on each spire to count up to 5 in binary. The hours are displayed by the middle LED in RED (Its a Red/Blue bicolor, the others … Read more
Here is a DIY high precision clock that is synced to the DCF77 atomic clock long wave radio signal. The radio signal is broadcast form Frankfurt at 77.5 KHz and has a reach of about 2000 Km. DCF77 is the name … Read more
Terry built a LED bar display clock using only logic ICs: Although I’m way too late for the 7400 contest, I had built a chips-only digital clock from 4000-series IC’s The time was displayed by columns of LEDs i.e. first … Read more
James built a digital clock that displays the hours and minutes on an old Nixie tube multimeter. The multimeter functions as a voltmeter that is reading the output of an Arduino generated voltage. There are still some noise issues to … Read more
ezflyr posted his GLCD clock PIC project: The project is based around the 75×52.7mm 128×64 Graphic LCD. The time keeping is delegated to a battery-backed Dallas DS-3231 RTC. A PIC 16F876A is used to tie it all together. The PCB was designed … Read more
