SMD Transistor LED Flasher Electronics Kit

With this kit you will learn to build a SMD two-transistor flasher that flashes two LEDs similar to train crossing lights. You will learn how to build a oscillator that generates a few pulses every second so that the LEDs flash. This kit is ideal for beginners who want to practice soldering surface mount electronic components to a PCB and learn how transistor oscillators work.
