I’ve departed from conventionality in that I’m using two NPN bipolar transistors plus an N-channel MOSFET transistor to create a soft flashing sequence using two green LED’s. Obviously it could be argued that there are simpler methodologies which could achieve the same outcome but I like the uniqueness this particular idea presents. Enjoy...😎
* Close the SPST switch located just above the 10V voltage souce to begin the flashing sequence *
PS: This circuit resists noise and works at any simulation speed if minor component values are altered. For example: A simulation speed of 1 ms/s would require you to lower the resistance of the 70K resistor to just 1K, also lowering the capacitance of the 100uF capacitor to 100nF and likewise lowering the capacitance of the 10uF capacitor to 500nF.
