Hi everybody, It has been a long time since my college and I wish to brush up my learning that I once did. I am in need of a wireless headphone and would love to construct one of my own. I understand that the basic concept is that I channel the output of my music system to a FM transmitter and receive it in a small FM receiver that I can carry around in my pocket and listen to through headphones.
If I am right so far, it boils down to constructing a FM transmitter. I came across some circuits, the easiest of which appeared to use BA1404 chip. Unfortunately, I could not find the chip. I came across some other simple digital circuits that used a set of NAND gates but I could not get it to work. It appears that a breadboard (of the type I am using to set my components on) is not suitaded for such fast circuits. Could anyone please me point to a simple circuit which:
- does not use too many components,
- works with stereo transmission (what is music without stereo, right?)
- is easy to construct,
- works on less power (cuz I do not need to transmit beyond maybe 50 feet), and most importantly
- is hard to go wrong with.
I would be very thankful for your kind help in regaining my lost love of electronics.
Cheers Gaurav
