Two phones donated components; a Nokia 3210 for its voltage-controlled oscillator and a Nokia 1611 for the rest of the parts.

That box you see on the side of the trash-can housing countains a starting circuit that shoots 30 kilovolts through the xenon lamp to get it started but it is separate from the power supply. [Ben] started experimenting … Read the rest

Panaplex displays are closely related to nixie tubes, but instead of layering individual numbers and lighting them separately, it uses pieces to build the numbers like a digital display. [Lindsay] managed to make one at home, using a jam jar as the vacuum tube. Argon as the gas in the tube gives … Read the rest
