Random number generator electronic kit from electronic goldmine

In this video I put together a random generator. It has 10 positions. You press the button and it will just go ahead and I would like to modify it to make it go a little faster and longer that’s the only thing but I love the kit and it was of a success for this YouTube video. .5 x 100 volts (squared) x x 40 pieces = 9.2 J 4000 V uF = 9.2 J
