Akafugu modular VFD clock review

Friday, July 14th, 2017

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...

Single tube Lethal Nixie clock

Friday, January 20th, 2017

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...

MSP430 VFD clock – Manhattan style

Tuesday, May 10th, 2016

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,...

PIC24 bedside table alarm clock

Thursday, October 8th, 2015

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. Standby current is with 5.5 µA only slightly higher than that of my MSP430...

Mini 7-segment clock v3

Monday, June 29th, 2015

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...

Open source binary wristwatch

Tuesday, March 10th, 2015

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...

GPS clock assembly, part III

Monday, January 26th, 2015

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...

Flashing a Nixie with an Arduino

Friday, October 3rd, 2014

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...

MSP430 propelled pendulum clock

Tuesday, September 30th, 2014

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...

DIY Binary clock in an old hard drive shell

Thursday, August 7th, 2014

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...

Nixie tube clock

Thursday, July 10th, 2014

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...
