[Laser] daytime receiver

[Jim Moss]

Andy,
One of the things you can do with that circuit, is change the pullup resistor
on the phototransistor for different gains.  Its not a great weak signal
detector, but it works nice for fooling around.  I've added red filters in
front and long tubes to cut down the field of view.
