Then 1N4148 or 1N914 will work fine. 1N4001 is over kill current wise but will also work.

Why is your schematic as big as my entire neighbourhood?
I think you have pin 3 (output) of the 555 mixed up with its pin 4 (reset input). Then the output of the 555 is fighting with the emitter of the transistor.

The huge schematic is full of huge spaces that could be cropped.
