What’s cooler than a Nixie Tube Clock? Maybe one that also has a WiFi-enabled Pandora radio. You may not be able to find exactly what you want in stores, but you could always build your own smart radio. jgroner has published a guide that shows you how to build your own Pandora’s Clock. This is a cool looking clock radio with WiFi, an amplifier, and speakers.
You are going to need a SPECTRUM IN-18 Nixie Clock kit, Adafruit Pi Plate, Raspberry Pi Model B+, WiFi USB dongle for Raspberry Pi, and a few other parts to get started. More information is available on Instructables.com.
