How to make a simple chaotic flasher for any number of LEDs

This is truly the simplest flasher, which gives a simply stunning lighting effect in total. Take and use any quantity LEDs and they will all flash differently. On the eve of the holiday, you can decorate anything with such a lighting installation.

Scheme


As you can clearly see, there are 4 identical cells in the circuit. They differ from each other only in the color of the glow LED, and everything is identical.

You can use any number of cells from one to infinity.
The transistor is turned on in reverse order, and the base hangs in the air - this is not an error, but the concept of how the circuit works. The transistor plays the role of a threshold guard. A charge goes through the resistor to the capacitor, and as soon as the threshold is reached, the transistor opens and all the voltage flows to Light-emitting diode. As soon as the capacitor is discharged by the LED, the transistor will close again. This sequence will be repeated ad infinitum.

Making a flasher


The entire circuit can be completed without a board by surface mounting.
Let's take it LEDs.

    Will KT315 be suitable?

    Tell. I assembled everything according to the diagram, it just glows and does not blink. What could it be?
