Plasma ball with nixie tube
We have already seen what nixie tubes are commonly used for and in that case all digits in nixie must be functional. In this case it is not important to have a fully working nixie tube, but the glass casing must still be in one piece. The tube will be used for pretty unusual purpose - plasma ball.
Plasma ball is nothing else than a glass sphere (or any other shaped glass container) filled with low pressure gas equipped with electrode in the middle. For operation, high voltage high frequency signal is supplied to electrode and plasma filaments extend from it to the outer glass insulator. As a power source, Tesla coil can be used or as in this project a modified neon lamp driver.
