> Just out of curiosity, are you:

Yes, I did.  I was trying on a 6 degree collimator.
> b) using lenses to focus your receiver?
> c) using long tubular light shields on your receiver?
Yes, to both.  I think it is quite a decent set.
> d) using modulation of some sort on your LEDs?
> e) using AC coupled, high gain, demodulation stages on your receiver?
Not yet, when I tune the receiver to be insensitive to daytime light, it 
can pick up my beam 10m away.  If it is tuned to be sensitive to my 
beam, the daytime light saturated the Rx.

> What baud rates are you hoping for?
Have not reached this state yet.
