Home made FM transmitter experiment.

Yep, CoolDudeClem is now on the air! And all it needed was a bigger coil. I couldn't beleive it, i decided to try a bigger coil, just to see if anything would happen, thinking this is never going to work I'm just wasting my time, but lo and behold when I tuned the radio I heard the transmition, I just could not beleive it worked!

Lol why waste your time just buy a transmitter i got a 10 Watt Fm transmitter for £50

@buzzn2011 That is true, but I wanted to make something that could fit in my pocket so as I walked around the house and talked I could be heard on any radio in the house. Besides, making something yourself and having it work really gives you a sense of accomplishment.

Respond to this video... man,can u tell us what was the modifications u made on that coil to make the setup working?

[CoolDudeClem]

@riky22lou I cant remember the dimensions of the coil, sorry, I know a lot of people have trouble when it comes to this part, I certainly did. All I can rememebr was that I wound about 6 or 7 turns of wire round a screwdriver, the best thing would be to experiment with different coils and see whitch one works.

Very Cool Clem!

What's the range of the transmitter?

Great work.(-:\>

I'm not sure how far it will transmit, i does seem to be able to go about 2 rooms away, maybe more. If you're talking about the requncy range, I can get it to trasmit on any normal fm frequency from 88 to 108 and it can go outside of that, but it works best at the lower frequencies.

how many watts per speaker does that boombox give, looks like it goes load with the size of the speakers, do you still have it ?

@CoolDudeClem Learn about dipole antennas mate, two 750 cms lengths of wire, one connected to where your existing antenna wire is on the circuit board, and another connected to the 'earthy' side (the - terminal of the battery) to act as a counterpoise will dramatically increase range, especially if you could get the thing up high or at least in a window. Pull one 'leg' of the antenna up and the other down, you could dangle it rom a curtain rail. Note: in some countries it's illegal to transmit.

@CoolDudeClem bro, u said in ur video description that "u needed BIGGER coil". what did u do to the coil, man, did u modify the winding diameter or the wire diameter, man?

CHEESE!! YOU SMELL OF CHEESE CLEM!!

I attenuation network with a few resistors might be a quick and easy solution...
