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

BD139 transistor
16v 4700uf capacitor
1kohm ¼w resistor
5mm led

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

The circuit is given above and I have made it in a different manner and made it in the form of a Skelton circuit
