Glen Akins’ PoE-powered vintage VFD tube clock: This is a vintage VFD tube clock that uses Ethernet for both power and data. The power is provided using 802.3at PoE+ and a Molex PD Jack that contains both integrated magnetics and a PoE Type 2 PD controller. The IP stack runs on a Microchip PIC18F67J60 microcontroller […]

WiFiChron alarm clock
Here’s a cool WiFiChron clock with 8-character alphanumeric LED display by Florinc: For WiFiChron, two cascaded modules make an 8-character display functionally similar to HDSP-2534, but bigger and more visible. With the “Display Abstraction Layer” already in place, software support should be easy to integrate, since controlling it with the HT16K33 breakout allows the re-use of […]
Neopixel clock, v2
David Zweben published a project writeup showing how he built a Neopixel clock powered by an Arduino Pro Mini clone and a real time clock module: After building my first Neopixel Clock, I decided I needed one for myself. There was no way I was going to solder 90 lengths of wire onto 180 tiny […]
Yet another Arduino clock
Sverre Holm blogged about his Arduino clock project: Its main features are: Controlled by a GPS module outputting data over an RS232 serial interface, and handled with the TinyGPS++ library Shows raw GPS data such as UTC time and date, position, altitude, and number of satellitess Shows derived GPS data such as 6-digit locator Finds local […]
Binary clock
Frederick Vandenbosch made a binary clock with Raspberry Pi Zero and Unicorn pHAT. He documented the whole process on his blog: At the center of the project are a PiZero and a Unicorn pHAT. The PiZero fetches the time, converts it to binary and controls the Unicorn pHAT with a Python script. The Unicorn pHAT’s […]
T-baneklokke – coundown clock
Joakim made a coundown clock for his wife and documented the whole process on his blog: The clock is built using an Arduino, and has a battery powered real time clock to remember the time while powered off. To make it truly stand alone I added the possibility to set the time and time-to-leave using buttons. The […]
GPS clock assembly, part III
An update on Kevin Rye’s GPS clock project we covered previously: I’ve been working on this clock for a long time, and a lot of effort has been put into it. I’ve learned so much from this project. I do have to admit some parts of the code aren’t as elegant as they should be, […]
Linux-based clock radio
An open-source Linux-based clock radio from SpriteMods: Ofcourse, a nice PCB with a powerful processor and a nice display only is scrap without the software: especially in this case, it pretty much defines what the device does. While developing the hardware, I already had made the decision to go with Linux and OpenWRT as an OS, as that’s […]
Simple xtal oven for accurate clocks
From the comments on our earlier HP 5350B OCXO repair post, a temperature controlled OCXO xtal oven: This is a very simple and easy to make temperature controller and heater to be attached to a xtal (crystal). The xtal is normally used to clock a microcontroller (PIC or ATMEL etc). Normally xtals provide an accurate clock to […]
XMega series: Clock system
Shawon Shahryiar’s second post of the XMega series is about the clock system, he writes: There are several clock sources that XMega micros can use as clock. These are both internal and external clock sources. As stated earlier, clocks are not set by fuse settings unlike traditional Mega AVRs, they are controlled by software and the […]
Bubble display alarm clock
Markus Gritsch build another bedside table alarm clock, the schematic and source code is available here: recently some vintage bubble displays popped up at various places [1][2], so I felt the urge to build another bedside table alarm clock, this time a really tiny one, roughly the size of an AAA battery. Check out the video […]
LCD clock version 2 – part I
Kevin Rye posted an update on his LCD clock project: Now that I’ve spent some time working with SMD Atmegas, I decided to redo the PCB to make it all SMD. By moving the Atmega to the SMD version, I picked up some additional space on the PCB. That allowed me to add a 4th button […]
A small GPS Arduino watch/clock
Here’s Oscar Liang another Arduino GPS project, he writes: Garlow stands for GPS Arduino Rechargeable Logger OLED Watch. The device gives GPS information which is logged on SD card and shown on a OLED display. It can be carried as a watch or simply used as a GPS data logger. The whole system is based on Arduino […]
Battery powered LED Matrix clock project
cburns shared his LED Matrix clock in the project log forum: My latest electronic project, the LEDC which is a LED Matrix clock. It’s the size of a standard business-card, and battery powered. I wanted something that would sit on the desk and I thought, why not use business card holder? It works great, and it’s […]
Add functions to your Dotklok: Remote control
Boris Landoni from Open Electronics writes about the Dotklok’s new feature, the addition of a remote control. We wrote about it previously here: The latest variation is the addition of a remote control, implemented with a few lines of code. This function allows you to read the signals sent by the common IR remote control used in TV, […]
Color wordclock project
EverLost shared his color wordclock in the project log forum: Display: It is now 2:45pm (Simulated, the RTC part is still WIP…) I am always fascinated with exotic clocks. You may have came across a DIY word clock before (if not, google it). This is my own flavor of word clock. Color, Traditional Chinese character, with a […]
Time plotting clock
A clock that plots time: The Time Plotting Clock mechanism is fantastically simple, 3 tiny servo motors allow the erasable marker to be moved along the drawing surface and raised when no contact with the surface is desired. This allows the pen to write the time. There is also a tiny eraser located in the […]
Turning your Flash Destroyer into a clock
voidptr writes: So ! …. 2 years later, here an update on living with my dangerous Flash Destroyer hack ! First off, front and back picture :o) I added few things since its birth … A battery for the real time clock, really handy when you reprogram code and you don’t want to lose the […]
Mini 7-Segment clock V2, part II
Kevin Rye writes about his Mini 7-Segment clock V2 project, we wrote about it previously: Now for the moment of truth. I crossed my fingers and connected a battery pack. Woo hoo! It works! I love that feeling you get when you spend weeks working on a project, it all comes together in the end and it […]
504 Segment clock, a 7-segment clock done differently
Bertho has designed and built this cool 7-segment clock, the 504 Segment clock: At some point I was being silly and got the idea of making a 7-segment clock, but then a bit different. The result became this. Features include: 72 7-segment displays in three rings; inner (hour) ring 12 displays, middle (minute) ring 24 and outer (seconds) ring 36 […]
