Topic: A very simple ir audio transmtter and receiver help. (Read 849 times) previous topic - next topic


I was thinking to build a very simple Ir audio transmitter and receiver for a very short range. My question is can it be done, the following is my plan:


A simple amplifier circuit, this will take my iPods input and amplify it to drive an ir led (audio pulses).


A simple amplifier again, it would have a photo transistor as its input and would amplify it to drive a mini speaker or headphones.

Is all this possible with a simple amplifier chip and a few components?

Basically, yes.
[Depends on how "a few" is defined.]

Here's just one example, the result of a web-search for "IR audio link" --

"You gotta fight -- for your right -- to party!"
Don't react - Read.
"Who is like unto the beast? who is able to make war with him?"
Hey, it's "bipolar transistor" or "junction transistor" - "BJT" is just stupid.
