are there any other downsides to using too big of a cap?
Quoteare there any other downsides to using too big of a cap?Cost and bulk are pretty big ones :-)
I think I am going to use a ceramic .1uF for this
I am kind of embarrassed, but I really don't know how to use an oscope, or the one she bought me in particular, came with no instructions. I am going to have to do some learning and digging.
What is a "PUT"?If the DVM was seeing a rising voltage then this is typically too slow for an O'scope to easily see.Try a 555 timer chip wired as a multi-vibrator running at about 1kHz to 10kHz. This will show up on the scope as a square wave when the scope's time base is about 2usec per division. Set the scopes vertical to about 1/10th of the voltage powering the 555.
