JL94 DUAL MODULE
IN 2012 I HAD THE OPPORTUNITY TO SEE A VIDEO ON YOUTUBE IN WHICH A YOUNG MAN PRESENTED A SMALL CIRCUIT THAT LIGHTED UP AN LED, WITH ONLY 1.5 VOLTS, AND THANKS TO THIS VIDEO I HAD THE IDEA OF DESIGNING A SIMILAR CIRCUIT BUT FROM 12 TO 18 VOLTS, FROM THERE MY JL94 CIRCUIT WAS BORN USING TWO POWER TRANSISTORS MJL21193 AND MJL21194, SINCE THAT DATE I HAVE USED THIS CIRCUIT FOR MANY OF MY PROJECTS. IN THIS PRESENTATION I AM PRESENTING MY NEW JL94 DUAL MODULE WHICH CONSISTS OF TWO TWIN CIRCUITS CONNECTED IN PARALLEL, FOR THIS TEST I AM USING A 12.5 VOLTS POWER SUPPLY. THIS IS MY FIRST TEST.
