Quad LED blinking

Wait for about a few seconds to see them change(the last LED takes a while to light up). You can see them light up differently.  In a few minutes,  the LED combination is different.

Not too bad Voltran! You have it a new twist. I highlighted the connections after the LEDs and is got a pretty cool scope effect too. Why go with the Darlington pair tho? Not questioning the design- just curious.. =^°

No PROBLEM, your fine. Lol. It amplifies very well with the darington pairs, darington transistors interests me. Lol.

Study some sziklai pair aka compound transistor pair it perform better in some cases than darlington. (Not exhibit high voltage drop between base and emmiter like darlington)

Oh, I've done those before. They are a great idea. I never knew that there's a difference between darlington and sziklai. So, szikai uses a PNP instead of NPN for the main transistor.

Like that, with 10uF it would even a visual interessting effect for humans and 500ms trigger source

I know, crazy! Lol.
