After mounting the components for the chaser circuit, the next step was to mount the LEDs to the Nixie tubes. The instructions warn that the dry time for the superglue on glass is quite long. After testing each LED, I used a "helping hands" component holder to keep the LED in contact with the nixie glass while I sprinkled some baking soda on the exposed superglue. This helped reduce the cure time and the process was slightly easier than I had expected. After drying for several hours, I cleaned off the remaining baking soda dust with a swab and water.
Dealing with all the nixie wires and the associated colored heat shrink was quite fun actually and I found myself soldering these to the board fairly quickly. Unfortunately, once I had finished and tested the circuit, I noticed one of the LEDs was malfunctioning. Not sure if I had screwed it up or it was defective. That was a real bummer because removing the nixie was a real PITA but it was child's play compared to reinstalling it once I received a replacement LED. Ladies & gentlemen, check those LEDs carefully before you solder to the board! For those interested, acetone melts superglue so removing the LED from the nixie was easy, only required patience.
I wanted to mention the great service I received from the seller, Spongeface
. I contacted him, explained the issue and he sent me a replacement LED. He really stands behind what he sells... even when the buyer is a dummy. Doug is real pro.
I don't have much in the way of assembly photos but I was quite pleased with how the LEDs and nixies turned out.
