Although the piece presented here attempts to merge lid and neck for a glass jar of crystal preserves in order to make Caesar's experiment published on December 23, 2015 at:\n\n\n\nTerrazocultor should also be recognized as the first to perform this type of experiments with seawater + oxygenated water, copper, zinc, and magnesium, which he perfected.\n\nOctober 31, 2011 \n\nMarch-2014 : \n\nApril 10, 2016 : \n\nApril 24, 2016 \n\nThe contribution of the "El Angelito" channel should also be acknowledged for using caustic soda as an electrolyte.\n\nJuly 25, 2013\n\nApril 28, 2014\n\nOn August 17, 2017 I added a piece that combines the lid with a Julio's latch in such a way that it can directly screw onto the crystal jar. The LED, switch, and potentiometer are all on the exterior face of the lid. The potentiometer replaces the 2.2 K resistance to better grade the voltage value at the base of the transistor according to the voltage. The transistor is of type BD137 NPN. On the underside of the lid, the component connections should be made following the scored tracks. The positive cable input is made through a lateral hole that connects with the track marked with the "+" sign. The other lateral hole is for the negative pole entry. The latch output coincides with the LED's terminals. The short leg (negative) must be placed on the side of the switch.
