✅ Взял древние транзисторы + устаревшую микросхему и сделал классную ВЕЩЬ! ✅

Hello everyone! Today I'll be building an interesting circuit using some old components: MP26 (MP40) transistors and a K155LA3 microcircuit. This circuit is called a flasher. Groups of 4 LEDs will light up sequentially. The circuit is very simple and reliable! The flasher circuit contains only 7 components (not counting the LEDs). As usual, I connected all the components using point-to-point wiring. The result is quite compact and attractive. A properly assembled circuit requires no adjustment and operates reliably. The only thing that can be adjusted is the LED flashing frequency. This is done by adjusting capacitor C1 and resistor R1. You can watch all the details on building a flasher using Soviet transistors and a microcircuit in this video! If you liked this video, then give it a like and subscribe to the Invexlab channel!
