Lantern Clock

Step 5 Closing her up

The components are now together,  using a multimeter check continuity from tube circuit board to wire end.
circuit boards (seen in step 1 pic 4) have a lot of traces in a small are, each tube has 12 terminals, the old board i had from pete required all 12 wires to connect to the board, his new prototype board has GREATLY simplified this, cathodes all tie in to the corresponding number cathode across the set of nixies for example cathode 1 tube 1 connects to cathode1 on tube 2 and so on, only the anodes (6 one per nixie) have to be connected one by one, not that hard at all

in picture 3 you will see the three pairs of wires to power the blue leds used for tube illumination, since the clocks board has a power in range of 9VAC to 15VAC. I chose a 9VAC transformer, allowing me 3VAC per led, so I wired the leds in series and connected the two wires directly to the AC input jack. since with AC polarity isn't an issue at 60 cycles they illuminate the tubes perfectly....
try and find an adapter with a 90 degree plug so you can drill and mount the power input plug facing down on the bottom cover plate.
the cover plated can be any thing from plywood to fiberglass circuit board material, i chose the later.bear in mind the recess you milled this depth will be your material thickness for the cover plate.
