2 grab your chance now, build your own nixie clock. Limited edition! What are ‘nixie’-tubes ? Nixie tubes are the ‘led indicators’ of the past. In the 50’s, 60’s and early 70’s there were no led’s or lcd’s. Neon gas filled tubes were used to display numerical data. They were part of scientific equip...
3 assembly hints 1. Assembly (skipping this can lead to troubles ! ) ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 make sure you have the right tools: • a good quality soldering iron (25-40w) with a small tip. • wipe it often on a ...
4 assembly hints 1.3 soldering hints : 1- mount the component against the pcb surface and carefully solder the leads 2- make sure the solder joints are cone-shaped and shiny 3- trim excess leads as close as possible to the solder joint remove them from the tape one at a time ! Axial components are t...

8 test & display 16 4 solder the female header connector to the display board. Connections at solder side! Mount the nixie tubes as straight as possible take care not to bend the leads! First solder 1 connection of each tube align and straighten the tubes, then solder a second con- nection check the...
9 assembly & test cut the pin header at position 17 so that 16 contacts are left over. Insert the header into the display board connector. Assemble both pcb’s using 4 spacers and 8 screws, make sure that the 16 pins come through the main board holes. Solder the connector to the main board, and cut t...
10 configuring and setting configuring and setting your clock apply 9-12vac. The clock will display '50' or '60' for 3s, depending on the ac power frequency (hz) in your area. This indicates that the zero cross detection part of the clock circuit is working fine. (if the clock displays '00', you eit...
11 configuring and setting to save energy and extend tube life, the unit allows you to blank the display for certain periods (e.G. At night, while you are absent, etc...) the digits on the left hand side of the separator indicate the hours (00 to 23). By pressing the button briefly, you can toggle b...
