In this video I show you my astable multivibrator with leds.
I used the schematic diagram from: [ Ссылка ]
The got the parts from a junk cassette-recorder. I had the LED's left over from another experiment, you can use LED's with other colors if you like.
The parts are: 2 NPN transistors, 2 capacitors 100mF/16Volt (use smaller caps for faster blinking), 2x 33kOhm resistor (orange, orange, orange) and 2x 2.2kOhm resistor (red, red, red). And don't forget to hook it up to a battery :)
