If you’re a real geek, you know that cathodes are super cool! The Nixie Tube Alarm Clock is truly a conversation piece, and its modern/vintage look is extremely impressive. Seven upright tubes that sit on top of this clock display the time in LED numbers.
Four of these tubes show hours and minutes, while three shorter tubes in front of them display seconds.
This is a great gift for engineering students, amateur radio enthusiasts or buy it and keep it on your night table.
