555 Timer RC Calculations For Strobe
This is for an extreme high intensity LED strobe intrusion deterrent. Extreme strobe disorients burglars even when they have flashlights. Calculator broke and cannot seem to access online RC sites....

Mex,
Why use an opto isolator? Why not just trigger the solid state relay directly (or maybe hit a one stage driver) (I think the 555 will only source 20 mA or so)- and eliminate the isolator and MOSFET?
It's a pretty tough device
