If you’re a fan of novel timepieces, then you’ll want to check out Christine Thompson’s VFD Alarm Clock.
The device features a USSR-manufactured IV-27V 7-segment tube, capable of displaying 13 numbers or letters via a 24V supply, though the MAX6921 chip used here means that only 10 grids are used.
10 characters, however, are plenty to show time, date, humidity, temperature, and pressure, plus the text “WAKE UP!” when an audible alarm sounds.
The clock runs on an Arduino Mega, along with an RTC module, a keypad, and secondary LCD screen on the back to assist with setting it up.
