Markus Gritsch shows off his Dot-Matrix MSP430 alarm clock. Via the project log forum.
Kerry Wong shows off his VFD clock he built after he completed the filament driver and the circuit to drive the multiplexed VFD segments we cover previously: After I completed the filament driver and the circuit to drive the multiplexed VFD segments, it is time to finish the VFD clock project I had in mind […]
Kevin Rye built this E-Paper clock and wrote a detailed explanation on his blog describing the build: I still have to put the finishing touches on the code. Instead of having the display constantly update, I’d like to set an alarm on the DS3231 RTC to go off once a minute, and only update the […]
Here’s a SevenBlocks project by Kiu, that is available at github: SevenBlocks is a digital clock resembling a classic red on black alarm clock, featuring a mechanic seven segment display of solid blocks moving into the viewers space. Via Hacked Gadgets. Check out the video after the break.
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 be just fine if there is a bit of money on the line if you […]
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 creations, the Doomsday Clock Arduino Shield. You can use it to countdown the final hours […]
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 and easily. Want to simplify hardware hacking? Get your own Bus Pirate for about $30.
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 I received one ringo3 PCB from forum member masteng. It’s having 60+60+12 LEDs (ss,mm,hh). The […]
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 by digit. It’s a clock made of a single IN-1 Nixie tube controlled by a […]
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 with Arduino bootloader and firmware preloaded. The firmware is written in Arduino, and is fully […]
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 large scrolling display.
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, controls the nixie tubes, and connects to the internet via the popular ENC28J60 Ethernet IC. […]
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 documentation can be found on Easton’s geekness website. Via the contact form.
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
