Frustrated with IR repeaters that use RF links (like Terk)... ambient
RF noise too high for reliable operation :-(
It occurred to me that since I have a central "Great Room"
architecture, that makes for a wide open optical shot across great
expanses... as much as 60' per link... so a purely optical repeater
should work nicely... pick-up the IR from a remote and blast an LED
with an Ampere ;-)
Ceiling heights of 12' to 16' and door openings of at least 8' means I
don't have to contend with people getting in the way.
So now I need pointers on how to collimate/focus an IR beam so it
doesn't spread out too much at 60' range.
Ideas?
