The Classic Two LED flasher

This is a circuit that works in a way that is not obvious on first encounter. So a great one to help you understand how a typical circuit of this kind operates. How the BJT transistor works, how capacitors discharge and charge along with the reasons why we need to set different voltage levels at the base of the transsitors. The theory video below carefully explains these details.

You will also notice that if you just remove one of the LEDs and just make a short where it was, you will then have a single flashing LED.

All kits that you buy will all come with two detailed videos, one will describe the theory the second video will show how to drill and adapt the tin so your board fits within it. (both videos are displayed on this page below)


Kit parts are as follows:
  • 1 of Resistor 50K
  • 2 of Resistor 3.9K
  • 2 of Resistor 470 Ohm
  • 2 of Electrolytic Capacitors 10uF
  • 2 of BJT Transistors 2N3904
  • 1 of PCB board
  • 1 of Battery clip
  • The tin (95mm x 60mm x 21mm)
  • Assembly instructions

The theory behind the circuit

The theory video is not required to get your circuit running. Those who are not interested in how the circuit works can just use the assembly instructions and refer to the second tin installation video for tips and an example on how to install the circuit within a typical enclosure. The theory is just an extra bonus video for those who like to know how their kits work.

All kits that you buy will all come with a tin as an enclosure. (96mm x 60mm x 21mm) This short video goes through some suggestions on how to install your finished circuit into a typical enclosure. Often the tins used in the installation videos is a smaller tin for demonstration purposes. But you will always receive the larger tin version.
