This is the home page for my VFD tube clock project, the TC18.
The TC18 is a clock built around an old Russian IV-18 VFD tube. You can read the story of how it came to be at this blog post.
I have a single clock for sale on eBay! This is the only one I will be selling, so please bid on the auction!
- IV-18 Russian VFD (Vacuum Fluorescent Display) tube for display.
- ATmega328P microcontroller running at 16MHz.
- Running Arduino bootloader for easy update.
- Completely custom firmware.
- DS3231 RTC (Real Time Clock) chip for keeping extremely accurate time.
- Lithium battery for keeping time during main power loss.
- MAX6921 VFD driver for controlling the 17 high voltage outputs.
- Custom high voltage boost switching power supply with voltage feedback; controlled by CPU.
- EEPROM storage of all configuration parameters.
- Rotary encoder with push to select for configuration menus.
- Custom aluminum enclosure designed by John Pfeiffer and realized by myself.
The enclosure of this clock was designed by John Pfeiffer at http://blog.giantpachinkomachineofdoom.com/
Some of the parts used in the schematic and board drawings are from the Sparkfun Eagle library at SFE_Footprint_Library_Eagle
