Vintage-style clock made from individual LEDs
— November 6th, 2018
If you’ve ever wanted a vintage-style timepiece, or to test your soldering abilities, this clock by YouTuber Electronoobs will let you do both at once.
It features four display modules that resemble Nixie tubes, each made out of LED filaments soldered onto a steel wire frame. If you find soldering enjoyable and relaxing, this is likely a good project for you; though if not, there are of course other options.
The device is controlled by an Arduino Nano, along with a MAX7219 display driver to power the LEDs as needed. An RTC module keeps things “ticking” at the correct pace, and a pair of buttons on top of the wooden enclose allow the time to be adjusted as needed.
I’ve made some “Nixie” tubes. These are actually 7-segment displays made with filament LEDs but placed in a plastic bottle so it will have a more vintage nixie look. To control the LEDs I’m using the MAX7219 driver that could control 4 x 7-segment displays. To get the real time, I’m using the DS3231 module that works with an I2C communication so it’s easy to use. The project also has 2 push buttons to set the hour and minute. All is inside a wood case painted with varnish so it will look more vintage.
