Fm Transmitter for MP3

[John]

Wife just got me an MP3 player for b/day.
Does anyone have any ideas or schematics for a low power transmitter that I
can connect to the player and receive on my car stereo in an unpopulated
part of the normal FM band 88-108Mhz.

Thanks.

You can get one ready made for $17.95 (which is probably much cheaper than
you could build one for).

Exchange it for a rubber suit and some vaseline.

Do a Google on crossdressing and ask the Woodgate about washing up.

You can get one much cheaper and more stable than you can make home made.
Radio Shack and many of the home audio stores sell these. Some of them call
it an FM sender, or FM Transmitter. Just tell them what you want.

I use one from Radio Shack, and it works very well.

Wouldn't the procedure make a Dirty bottle?

Well, what do you know, nice to see you intelligent, intellectual and
supportive guys that make the world 'tick' have something constructive AND
of interest to mumble, I am so glad to have posted here.

John.

Nothing prevents you from persuing your project.
But the fact remains that this device already exists, and volume production
has pushed the price down lower than you could buy the components for.

Stereo encoding isn't simple. You'll also have a bit of a time with the PLL
design, since FM transmitters are wideband FM, and the PLL will "fight" you.
FMing the reference osc works, but then the deviation changes as you change
output frequency.

Do you think you can solve all these problems for less than the price of a
good lunch?

 

[John]

Thanks Dave.
No, but now you have been gracious and polite enough to advise me on the
difficulties I understand the reasons and can find another project. But
unless someone advises (teaches) then how is one to know.
John.

I like that.

Interesting, I thought my head was so far down my neck it had popped out of

John.

If you want to do it to learn about PLLs, and stereo encoding, then by all
means go for it.
Frequently, my projects cost way more than it would to just go buy one.
But if you're doing it to save cost, you're barking up the wrong tree.

My current "project" has been quite educational, at the expense of >$1.5M


There are some FM transmitter kits that might do the educational end, while
allowing you to start with a design that is known to work. Look on the
Ramsey website.

I've always said, "When I'm done learning, get a shovel".

The problems have already been solved. See the Rohm BH1416 data sheet
for a schematic.

Maxim/Dallas Semiconductor has a chip that does what you want - if
your eyesight is good enough to solder it onto a board!
