You still need to know how to read the datasheet and make sense of it after some fashion. Now simulation isn't reality and parts vary widely (especially these parts.) But at least in the simulation world you can see how closely my use of the datasheet and theory was able to predict what Spice plotted out. Pretty amazing, actually. Of course, Spice uses ideal wires and power supplies, etc. And parts vary. So while theory tells you why and the datasheet tells you approx. behavior, reality may sill need addressing, too. | |

| Apr 2, 2019 at 10:19 | comment | added | jonk | Thanks for the update! I'll take a moment when I get a chance and test out my own work. If it also fails, I'll work out the issues further and let you know what I find out. If it works, I'll just say so. Yes, pujt devices aren't used much and I stopped using them years ago, despite having lots of them here. But being relaxation oscillators capable of using high impedance results, they can be quite efficient when they work. Thanks again for the update. | |
