These are what got me started in electronics. My dad would make them for presents. One of my uncles gave me the one my dad gave him when I was like 6 years old.
I have pictures of the original my dad made one as well as a new one I using the same circuit, just laid it out differently. The schematic is in there as well. https://www.dropbox.com/sh/2v5wr5vmf3ksafu/KYN2r0qa4x For power, I use a little power supply board from allspectrum.com http://www.allspectrum.com/store/nixie-power-supply-high-voltage-switch-mode-dc-dc-converter-kit-95-190vdc-25ma-180vdc-p-521.html -joe On Thu, Apr 3, 2014 at 2:26 AM, petehand <[email protected]> wrote: > Does anyone remember these things? > > Brits will deduce the era of this device from the currency.
