uh, I don't read Arabic. Is there a better translator than the Google translator?

Or maybe I didn't guess the correct language?

 

[Mikebits]

Maybe it is Farsi?

 

[mneary]

I pasted a few phrases from the website. The Persian and Turkish translations made even less sense than the Arabic. And Google won't import the whole page so it's just one phrase at a time.

no it is not pharsian it arabic i can helb you to traslate it my name is maher this site is named electronic village or القريةالاكترونية in arabic if you want to know the mean of any word tybe it and i will translate it to you

Out of the 37 links, only 14 produced a page with a circuit that could be built. The other circuits had no coil details, or just unrelated photos. Where are the 100 FM transmitter circuits?

Thank you for the offer. I cannot type it because my keyboard doesn't have those characters. The owner apparently doesn't allow Google to read his pages. Google Translate can also also give me one word or even phrases if I copy pieces into their little window. Either way it would take years for me to read a few pages.

It looks like the list was written three years ago. Thank you colin55 for sorting through the list and identifying those that still might be useful.

I admire people who can speak many languages, but I am not among them.

 

[maher2030]

you are seriously colin55 i took them from this site but i did not count them by any case thanksfor posting them

Leave the guesswork to Google if the whole thing is in one language. Usually, the outcome is based on the right language but what comes out from the translation tends to be in the funny side.

Anyway I would say, "better this than nothing").

Did anybody notice that most of the FM transmitters have the same problems:
1) The antenna is connected directly to the tuned LC of the oscillator so anything that moves toward or away from the antenna changes its capacitance and changes the capacitance of the tuned circuit so the frequency changes all over the place.
2) Most circuits do not have a voltage regulator so the frequency also changes as the battery voltage runs down.
3) Most circuits do not have pre-emphasis (treble frequencies boost) so the de-emphasis in every FM radio will play them with a muffled sound like your stereo with its treble tone control turned all the way down.
4) Most circuits are mono, not stereo. The BA1404 IC is stereo but it is obsolete and its RF frequency drifts all over the place.

The BH1417 circuit is modern, has a quartz crystal controlled frequency synthesizer for a rock solid RF frequency, has pre-emphasis and is stereo with fairly low distortion. Throw away 99 of those old poor performance circuits.
