Gillian's Diamonds LED crystal remix. Full build.

Long video, so feel free to skip bits if you wish. This was a project to make a small PCB that fits onto the bottom of a glitter lamp bottle and uses resistors to provide thermal liquid flow with LEDs powered via the resistors to provide the illumination. It works well with the common plastic diamonds sold as wedding scatter table decorations. The buoyancy of the liquid is adjusted with common table salt.
I'm toying with making a USB powered version for safety.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
