Dunno yet! No (and I mean NONE) costing has been done yet!

? - i Just borrowed the values from another circuit thart used the 555 to
modulate the IR for use in a IR extender

Send out the modulated IR, when there is an object near, the light bounces
off it and hits the IR detector (U60, or ratshack IR detector)
