This is so simple circuit But you can use this circuit as a Christmas star.Here I have used famous transistor 2N3904.If you are unable to find this transistor you can use D400 instead of that.This circuit operates with 9V.I used this circuit for the last Christmas If you used Blue color LED s It would give inexpressible attraction.
Note
# If you want to change the speed of this circuit You can do it by changing the values of 10uf and 100k
# This circuit can be operated with 9V power supply
# Fix this circuit on a pcb
