The entries for our Fubarino contest are slowly yet surely coming in. [James] already had an awesome VFD clock under his belt, and figured adding a Hackaday easter egg to his project would be simple enough.
[James’] clock is based on the TI Stellaris LaunchPad with six beautiful seven-segment VFD display tubes. The clock’s time is controlled by a DS1307 RTC chip, and a small switch-mode power supply controlled by the Stellaris boosts the power from 5 Volts to 50 Volts for the tubes. The tubes are controlled with a Max6921 VFD driver chip.
The easter egg for this project – displaying the Hackaday URL – is only shown when you power up the clock when the seconds display shows 37. That’s extremely subtle for an easter egg and just the way we like it.
All the code for [James]’ project is up on GitHub along with the designs for the tube clock’s enclosure. Really an awesome project, and a great way for [James] to earn himself a Fubarino.
What are you waiting for? We still haven’t passed twenty entries which means your chances of winning are pretty good!
