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 made for 0.8mm drilling (truly DIY). Just around 5 vias are under a component and […]

Binary Burst clock ticks away the time with LEDs
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 are just blue). Video, and links to the board and code repository are included in […]
DIY high precision clock synchronized with an atomic clock
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 of a german radio station on 77.5 KHz, which gives official time and date from […]
DIY clock based on 4000-series logic ICs
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 columnt was 1-12, and the led for that hour would be lit. The next column […]
Digital clock from an old nixie tube multimeter
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 clear up, but all in all it’s a cool looking clock. Check out the video […]
DIY GLCD clock project
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 to fit nicely behind the display. It is operated via two push buttons, which allow […]
