Manuel Azevedo did a review of Akafugu’s modular VFD clock: I discovered this wonderful tiny VFD clock by chance, while browsing Tindie for novelties. As I’m a newcomer to this Nixie/VFD world, I was not aware that Brian Stuckey already did an article in 2014 on a previous incarnation of this clock (Akafugu Modular VFD […]

Single tube Lethal Nixie clock
Andrew Moser made a lethal nixie tube clock: Clock 1: Single tube Lethal Nixie clock — you know having all the high voltage lines exposed and un-insulated. Inspiration for this design was from this clock. Unfortunately I built mine right after having surgery. I think the painkillers had something to do with the aesthetics… Anyhow […]
Adjusting clock with alarm, hygrometer & thermometer on 1.8″ ST7735 display
Nicu Florica blogged about his adjusting clock with alarm, hygrometer and thermometer on 1.8″ ST7735 display: I use feature from article Another adjusting clock with alarm & thermometer using DS3231 on 1.8″ ST7735 display and change reading internal temperature of DS3231 with DHT22 senzor (AM2302), but you can use a cheaper and not very precise DHT11 […]
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 […]
Linux alarm clock
Benoit Frigon wrote an article detailing his alarm clock running Linux project, that is available on github: This is the display i made for my alarm clock project. The first version was a 24×7 LED matrix but later changed the design for a four digits seven segment display. I decided to keep the drawings for […]
MSP430 VFD clock – Manhattan style
Daniel has a nice write-up about building his Manhattan style VFD Clock based on the MSP430G2553 microcontroller and the MAX6921: I know that and IV-18 based clock isn’t anything original. In fact, Adafruit used to sell a kit for this exact purpose. I don’t really care that it’s not original, because all vacuum tubes are […]
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 […]
PIC24 bedside table alarm clock
Markus Gritsch posted pictures of his PIC24 bedside table alarm clock in the project log forum: Another year, another clock, but for the first time for my alarm clocks, I am not using an MSP430 but a PIC24 instead. During the development process, I came across some interesting discussions about betting sites not on BetStop, which led me […]
Mini 7-segment clock v3
Kevin Rye has written an article detailing his new Mini 7-segment clock v3. We previously covered version 1 and version 2: I hope the LEGO minifig gives you a good sense of scale. This clock is pretty small. It’s amazing how small the Mini Clock has become after just 3 iterations. Just look at how […]
Open source binary wristwatch
Jordan aka njneer made this cool binary watch project, that is available at Github: I’m pretty proud of this project; the clasp is a ribbon cable that doubles as the programming interface for the PIC microcontroller that drives everything. The time is displayed with superbright LEDs that are blinding at 15 mA, which means that I’m able to […]
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, […]
Free fun flexible watch
F*watch team writes: The F*watch, a fully open-source electronic watch project with an integrated GPS receiver, was initiated at CERN as an after-work endeavor to create a special retirement gift for a colleague who enjoys hiking and timing. Inspired by the transparency and flexibility that characterizes no verification casinos, the watch’s entire design—including electronics, mechanics, […]
Flashing a Nixie with an Arduino
Kevin Rye writes: I’m in the very early stages of prototyping a nixie clock. I picked up some MJE340 power transistors to switch on some IN-3s. I can then use a digital pin on my Arduino to turn on the IN-3s through the transistor. I’ll then have myself a blinking colon for my nixie tube […]
MSP430 propelled pendulum clock
DickB over at the 430h forum built this cool MSP430 propelled pendulum clock: This pendulum clock is not only regulated by the pendulum, but it is driven by it. A hidden magnet in the pendulum swings past a hidden coil and induces a current. This is detected and then a current pulse is fed into the […]
Hard disk drive clock with Arduino Uno
ACVoltage wrote this instructable detailing his DIY POV clock using hard disk drive and Arduino Uno: This is a fun project that can be done easily and also cheaply. In this instructable we will explain step by step how to make this beautiful POV clock. Used material: -Arduino Uno, -Tiny RTC modul, -ULN 2003, -IR diode and IR transistor […]
DIY word clock
Want to build your own world clock? Check out Wouter’s DIY word clock instructables: …I have found one DIY project that really stands out: Elektronika.ba’s wordclock, proving that it is possible to build your own wordclock that is as pretty as the original. Also, here is a video of the manufacturing process of the original: […]
Voltmeter clock project
Here’s a voltmeter clock project based on a multimeter clock design by Alan Parekh: I have used three voltmeters and mounted them on a wooden plinth with a clear Perspex cover to give the clock an industrial look. I have modified Alan’s code to run on PICBasic Pro version 3. I have also added the […]
DIY Binary clock in an old hard drive shell
x2Jiggy wrote a post on his blog detailing the build of his DIY binary clock: This clock uses a minimalist design constructed in the shell of an old hard drive. A DS1307 Real Time Clock (RTC) module keeps accurate time while an ATMega328 (with Arduino bootloader) microcontroller determines which LEDs should be lit to display the current […]
Nixie tube clock
Tom Cousins of DOAYEE made this DIY nixie tube clock: Below is the schematic for the project, as you can see I’m using 6 IN12 nixie tubes, each with it’s own 74141 nixie tube driver. These drivers are great! They simply connect directly to the nixies and display whatever 4 bit binary number you give them […]
