Thanks IST,

What is so helpful for me is that it is just the same picture of a waveform that I get over and over. Sometimes close together sometimes tall or short and tall, but the pulse almost always looks like that.

I mean, now I know the scale. It is the pulse that looks like that. It is not just a part of a pulse, but the pulse itself.

I am still trying to figure out what I am seeing because I am so new to the scope.

thanks a lot,

EDIT add

the freq is 1.4 khz

when i intrupt it

In other words when you pulse the pulse?

@ pirate
i wonder if one of those little supercaps would fit in these canisters. that would be neat.
here is a pic of a jt flashlight conversion i did a year or so ago. i took apart the incandescent bulb and used its base to make a new led bulb with an incandescent screw in socket. i wasn't paying attention and soldered the bulb to the base with the polarities reversed so i need that silly little redwire that goes from the jt to the battery. i used a piece from the tip of a multimeter probe for the black spacer to make it the length of a battery and cut a section of drinking straw to make a cover for the circuit and filled the voids in it with epoxy. i can try and take a close up of it if you want. long story short, been looking for a nice sized thing to do this with and this battery case in the grizzly led light is perfect.
