High Voltage Switch Mode Power Supply for Nixie Tubes
This SMPS boosts low voltage (5-20 volts) to the high voltage needed to drive nixie tubes (170-200 volts). Be warned: even though this small circuit can be operated on batteries/low voltage wall-worts, the output is more than enough to kill you!

PIC16F84A Nixie Clock
That’s a very compact nixie clock based on PIC16F84A and 74141 driver IC and MPSA92 high voltage transistors.

Nixie Clock
The Nixie Clock uses the Make Controller’s Ethernet capabilities to go online and check what the time is, via a protocol called NTP (Network Time Protocol). Once it determines the current time, it uses the digital outs on the Make Controller to communicate with a pair of custom circuit boards that drives the nixies and updates the time. [via]
