555 Timer

[tooobiCH]

Hello

Ive some problems with the 555 Timer. I'm trying to get an defined pulswidth signal out of a current signal.

My problem is the circuit should work with 0.25 to 1 Hz on the current signal.  I've got it running at 1 Hz but if i try to go lower the timer starts to get crazy.

im a really noob in stuff like that and happy with every little help

i hope someone can help me

thank you
