I will need the range of the IR to be somewhere in the neighborhood of 30-50+ feet.
I will only be using 1 gun so I won't need to worry about detecting different frequencies.
Too far for an IR LED, you might have to go for lasers.
Adafruit sells a device that transmits only the "OFF" code for every tv code known. You could use that and a photo... what a waste...
. A 2 - 5 Mw IR laser diode makes the gun.
I assume the non reflective tube will only emit a narrow beam
BUT the issue that I think every one has missed in a misguided attempt to display their electronics knowledge is that the OP has virtually no electronics knowledge and limited resources and is virtually incapable of following any direction provided here, as he has stated twice..
"virtually incapable of following any direction provided here" statement.
I did mean mW not Mw although it should have been MW had I intended Megawatts of energy..
