Tully shared his Doomsday clock Arduino shield in the project log forum: Here I would like to log new innovations that can be done using the Doomsday Clock Arduino Shield. A recent innovation completed by Devin Sean McCullough, is a web-based … 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.
Tobias Floery built this RGB pixel clock and wrote a detailed explanation describing the build. These RGB Pixels look like they are fun to work with since they are so versatile. Tobias Floery is having some fun building an RGB … Read more
Markus shared his QR clock in the project log forum: being inspired by ch00ftech’s QR clock I made my own variation of this nice idea: A PIC32 decodes the time signal from a DCF77 receiver, calculates a QR code containing … Read more
Mats continues his challenge of designing one PCB every week. In week 4 he came up with RetroTime, a digital clock with RGB LEDs in 12 tentacles extruding from the body of the PCB. Next week I’ll do a slightly … Read more
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
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
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
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
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
Haris built this handsome IV-11 VFD clock and wooden case. VFD tubes are similar to Nixie tubes, but use much lower voltages. Via the forum.
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
Luca is designing a nixie clock that will be run from an Arduino. In the latest development he shows to to implement a real time clock source and a port expander to drive the nixies. In this third blog post, … Read more
Mick decided to build Vetinari’s clock based on WaitingForFridays project. Lord Vetinari, from the Discworld book series, has a clock in his office that is designed to make his visitors feel uncomfortable by having the second hand move at irregular … Read more
Ok, so you burned all the memory chips you had around, and now a nice 7-digit display is standing on your desktop just taking up space. This hack turns your unused Flash Destroyer into a clock using a real time … Read more
Matt’s entry in the Open 7400 Logic competition: Discrete logic POV clock. This persistence-of-vision clock was built entirely out of discrete logic chips. The design consists of three boards, a LED array and a drive motor. The digit board keeps the time while … Read more
Our 7400 competition is heating up, Andrew form Ajax Electronics entered his New Earth Time digital clock into the competition. NET is a new way of telling time using earth’s rotation in degrees and minutes. 24 hours is 360 degrees, and each … Read more
DolceVii posted his old clock made with only gate ICs for the 7400 competition. Via the contact form.
