would this IR sound transmitter work probably ?
i was looking for an easy and good circuit to transmit sound over IR
i searched using Google and found some circuits
the first one
i found it on many sites and they say that it's working
but the problem is that i can't find some essential parts in the stores where i live
(the transformer ,bd140 or sk100)
the second one
is very easy and i have all the parts except for The UM66 which i think can be replaced with a 555 astable circuit to produce some sound
but i want to know if it's possible to replace the UM66 with some sound source (TV , Mp3 player ,PC sound card output) ?
if you have a tested circuit please post it here
