A PCB badge featuring the iconic brain chip from Terminator 2: Judgment Day. This is a tribute to the Terminator's 40th anniversary! (1984-2024). Terminator 1 was the first movie I ever saw in a movie theater when it was released in Germany in 1985. I lived in a small town at the time, and the theater still had the flair of the 1950s. It was this movie that got me interested in robotics.

$Powering a Geissler tube by hand #wimshurst #geissler #helium In this video, I show you how to operate a Geissler tube with a Wimshurst machine. The Wimshurst machine is from AliExpress, and the Geissler tube is from eBay. Geissler tubes are filled with various gases at low pressure, with metal electrodes at each end. A high voltage of several thousand volts is applied between the electrodes. The high voltage ionizes the gas, causing it to give off light by fluorescence in a glow discharge. The color of the light depends on the gas used. To give it a vintage look, I made a new base from lime wood and tube holders from turned wood. I also made the brass wire connections myself and paid attention to other historical details. My Geissler tube is filled with helium. I checked this with a diffraction grating by looking at the spectral lines.$
