Jeffrey sez, “The renowned 360 photographer Andrea Biffi has posted complete instructions for building your own Nixie Tube clock, even including how to etch your own circuit board.
While the process seems to be slightly more difficult that ‘total noob’ difficulty (also, with nixie tubes, hazardous voltages are involved, so be careful!), it looks like loads of fun, with an absolutely beautiful end product.”
