NIXIE CLOCK DIY
Solder the LED ,plug the LED on the bottom side of PCB,the lighting side face on the top of PCB,sware the first leg of LED as shown on Pic.
LEDs are heat sensitivity equipments, if possible, use 130C low temperature soldering wire,or use a slice metal(the pic shows back side of a paper knife blade) as heat sink,the solder the LEDs,and if possible,protect the nuxie holes by using kaptin tape.
Solder the socked pins of Nixie tubes. First plug all female pins from the top side of PCB,then clip it on by using a small size PCB on the top with a clip.
Flip to the bottom and solder all pins on.
When done
Solder the HV module 5 pins female sockets.Same clip on skill.
