Nixie Tap: Minimalist Wi-Fi Nixie Clock

Nixie Tap is a compact and simple Nixie clock. It's powered via a micro USB connector, so you can power it from any USB port or an old phone charger. It also has Wi-Fi, so it can automatically synchronize with an NTP time server once connected to a wireless network. We made the Nixie Tap look good on our desks, and we hope it looks good on yours.
