Nixie Tube Thing – Dirty PCB to the rescue!

Tuesday, December 30th, 2014

Crawford writes: I have been lusting over the Nixie Tube Driver that Ian brought to the 2012 World Maker Faire. When I met him there I asked about board production, but he explained it was a one-time thing. Fair enough. Well it's 2014 now and DirtyPCB exists. I grabbed the...

Designing a high voltage power supply for Nixie tube projects

Monday, May 5th, 2014

A PCB layout for the switch-mode HV PSU by Jan Rychter: I've posted a page describing the design of a HV PSU (High-Voltage Power Supply) that generates up to 220V from a 12V input. In addition to that, it also provides 2*Vout (so, up to 440V, for dekatrons), and two outputs...

WORKSHOP VIDEO #39: Magnificent Nixie tube thing

Thursday, September 13th, 2012

[embed]http://www.youtube.com/watch?v=29tT2knWV7Y[embed] This week we try out the IN12 Nixie tube blocks we've been working on. They'll be on display in the new workshop studio and at Maker Faire New York. We also light up a mini VFD we scored in Akihabara in Tokyo last year. Sorry about the poor lighting,...

Buy a vintage calculator get 8 Nixie tubes free

Thursday, March 15th, 2012

Philip scored a vintage Sanyo 4 function calculator in a local thrift store. He opened it up and was pleasantly surprised with 8 Nixie tubes. You guys wont believe what i just scored from a local thrift store [selling second/third/fourth hand stuff from japan] :) A good old 4 function...

Test Nixie tubes with a flip of a switch

Thursday, December 29th, 2011

[embed]http://www.youtube.com/watch?v=pSZMMpjQ5KU[/embed] This Nixie tube tester has an 11 position switch to change the displayed digits. A simple device for testing and/or healing Nixie tubes of IN-18 type. An 11-pole switch is connected in series with a 50 KΩ pot (+ 470 Ω resistor for safety), powering from an 180V DC...

App note: HV boost power supply for Nixie tubes

Sunday, December 18th, 2011

Here is a app note from Microchip describing how to implement a high-voltage boost DC-DC converter intended for Nixie tube designs. The basic principle of Nixie tubes is that they require more than 170V to function properly. This design uses the internal PWM generator of a PIC16 microcontroller to drive...
