Circuits Designed by Dave Johnson, P.E. :
LIGHT DETECTORS WITH AMIBIENT LIGHT COMPENSATION These circuits were taken from a few application notes on infrared remote control devices. They use a current compensation method to separate the modulated light pulses from ambient light.
They appear to have limited bandwidth and may only work at the 30KHz to 50KHz frequencies often used by TV and VCR remotes. I have not yet tested the circuits.

Mail's Here: A Deviceto Let You Know When Mail has Arrived : A year or so ago, the combination of an outside mailbox and a
cold, stormy New England winter gave me the impetus to build a gadget that would let me know when my mail had been delivered. 'After all' I thought, 'what good is an engineering degree if it
can't save me running outside half-a- dozen times a day to check the mail? Gadget Freak / Design News (Circuit / schematic design added 6/06)
