| Feb 24 at 21:20 | comment | added | JSK | OK, thank you! One more question, which resistor could be used as a potentiometer to control the delay? | |
| Feb 24 at 20:55 | comment | added | Jens | @JSK The circuit is perfectly symmetrical, so if it works in one polarity it must work in the other as well. | |
| Feb 24 at 20:52 | comment | added | Jens | @JSK The embedded CircuitLab simulator in this site has no problem with this circuit, try it here and look at the time domain simulation. Did you set a GND reference in you simulator? | |
| Feb 24 at 20:13 | comment | added | JSK | Thank you for so descriptive answer! I simulated both circuits, the first one works fine and the second one gives me an error "Convergence failed" (in one current direction it's also fine). Is it only a simulation error which I shouldn't worry about? tinyurl.com/28ev67kq | |
