Fire up the soldering irons and grab your Nixie tubes! Time to heat up the cathode and bask in that cheerful glow of warm electronics. Before you ask what the heck a Nixe tube is let me tell you. Long ago back when ‘solid state’ meant frozen, if you wanted to have an indicator lamp you used a neon bulb. You pass electricity through a glass tube that has neon in it and you get light. Very nifty. Even more nifty is that the light tended to cling to one of the electrodes and some brilliant guy thought to make useful shapes with them and thus the neon multi display was born.
Some of the voltages here are a bit high, so if your not sure about your 733t electronics skillz you might want to get some help with this. Once you have the hang of getting these old gems to light up you can interface them to things other than clock circuits and add a bit of warmth to your projects. After all, it’s not a real electronics project unless something glows.
