I find a fairly simple explanation:

I am hopeful to get pulse rates from 120Hz to 1200 Hz with a lot of interest near 530Hz the current w/b about 650ma as with the 635nm 300 mW it is about the limit. -Glenn

One question I have -
We get a square wave out of the 555, but does that translate into a square wave after the DDL ?
I was bored so I drew up the 555 pulse circuit (I hope that Sigurthr won't mind) in Eagle and designed a pretty SMD board for it - it is 1.5x0.7 mm and the pot is 5 turn.
