LED flasher with two transistors

Today I will tell you how to make a simple flasher on two transistors. This homemade will help beginner hams in the development of radio electronics. Materials for creating emergency lights can be found in any electronic store.

To create an emergency light we need:
2 LEDs (any color at 3 V)
2 resistors (at 330 OM) and 2 resistors at (at 22 KOM)
2 capacitors (at 16 V and 20 MKF)
And 2 transistors (KT315)
Well, a 5V power supply

We will collect here according to this scheme:
To begin with, we need to solder the pluses of the LEDs to the + power supply, and the minuses to the resistor (by 330 OHM). Next, solder the resistors (to 22 KOM) to the + power supply unit so that one “leg” is on the + power supply unit, and the second on the minus of the capacitor. Next, we must solder the + capacitor to the resistor (at 330 ОМ) .Then we must solder the transistors (be careful, the transistors quickly overheat). The emitter to the - power supply, the collector to the + capacitor and resistor connections to 330 OM, and the Base to the connections - the capacitor and resistor at 22 KOM. (in the picture BKE) Well, that's all it remains to do is connect the power supply to the network and enjoy the flashing LEDs. The flashing frequency can be adjusted by changing the resistance of the resistors.
