Introduction: Bd139 Flasher
This is a led flasher Circuit made out of an BD139 transistor
Here is the link to watch the vedio(language-malayalam)- https://youtu.be/PApGB6Yrrm0
Supplies
BD139 transistor
16v 4700uf capacitor
1kohm ¼w resistor
5mm led
Step 1: MAKE THE BASE
The base for the flasher is made out of wood and cut into a square piece .and some holes were drilled in to wood and a small strong copper solid copper wire is inserted in to the wooden platform to so that the components could be soldered on
Step 2: MAKE THE CIRCUIT
The circuit is given above and I have made it in a different manner and made it in the form of a Skelton circuit
