Small portable PIC16F84A driven Nixie clock

Most of Nixie clock designs end up with at least four indicators that display time at once. More Nixie indicators require more space and power. But pinomelan decided that single digit IN-12 Nixie indicator is more than enough for building small portable digital clock. He put small PCB with PIC16F84A which drives single Nixie with discrete transistor. Nixie tube needs high voltage to light up, so he used HV supply from disposable camera. Clock displays time by periodically flashing all digits in series. During display each digit can be set up by pressing button at the right moment. Nixie clock along with battery could fit in to 35mm cube enclosure if needed. Continue reading

Arduino Nixie tube clock

Clocks with Nixie tubes always look great and old school. Building one isn’t that hard. Tom has been building one around Atmega328P with Arduino bootloader. His clock uses six IN12 nixie tubes along with 74141 driver chips. Data to digits are passed through three 74HC595 shift registers. Correct time is kept using DS3232 real time clock chip with battery backup. Clock is covered with acrylic sheet that makes it look good. Three push buttons allow easy setting of time.

Nixie clock lacks PCB

We’ve seen lots of interesting Nixie clocks but this one definitely leaves impression. The fact itself that it is build without using a PCB draws attention. Its a free-form wiring creation. Its driven by Atmega8 microcontroller which drives high voltage transistors. Of course there is a high voltage circuit floating and as someone is joking – its second feature might be bug zapper. Author claims that schematics and firmware has been lost so enjoy the action video. Continue reading

Nixie clock with RGB LED backlight

Nixie clocks add nice touch to living or working place. They look, great especially with unusual design. Akafugu brought new breeze in to nixie clock club. He decided to add RGB LED backlight that adds even more beauty. He’s chosen Russian IN-12 Nixie tubes that as we know require about 180V to light up. So he made a step-up voltage regulator that rises voltage from 9V DC to high voltage. Clock circuit is based on Atmega328P microcontroller. It reads time values from DS3231 Real time Clock (RTC), drives RGB LED backlight and reads rotary knob and button for controls. Clock building process is well documented and is open source. IF you like it – shouldn’t be a problem to build one. Continue reading

Open source nixie clock v2

Thax has been busy on improving his open source nixie clock. He made first version of it some time ago but found few things that needed to be improved. So here it is a second version of “Warm Tube Clock”. Clock is run by Atmega328 microcontroller. But to make it more precise and easy to manage timekeeping is done by DS3231 RTC IC. It also has ability to measure temperature which is also included in feature list. Continue reading

Ice Tube Clock – The Coolest Vacuum Fluorescent Display Clock

Some people are craving for the coolest stuffs/gadgets, as a part of them didn’t even care to spend money out from their wallet, just want to buy the coolest digital stuff for their loved ones! Well, for those who enjoy making their own gadgets, maybe this Ice Tube Clock is going to be your next cool electronic project! As you see on the above figure, the icy blue-color ice tube clock is simply amazing. Look on the stylish and sophisticated design! Isn’t it the high-end digital clock that you’ve looking for all the time? Well, the journey is ended here, as you can now start to build a spectacular Ice Tube Clock immediately. By the way, there are several things that you need to careful, before you start the building project. The Ice Tube Clock is operated on a high voltage, which is ranging from 40V to 70V DC. Therefore, if you’re not familiar with the electronics, then it’s good to learn the fundamental electronics knowledge first. Please take note that the assembled unit must be properly enclosed. It’s to… Continue reading
