Does anyone have some links or projects of jammers that are powered by an arduino?

NOTE: Before you come posting on this thread about it being illegal. I know the laws and where I'm from (USA) it is not illegal to use a jammer on your privet property as long as the jammer does not exceed your property line. Go look it up if you think I'm wrong!

Not much to jam at 100hz ?

No you prove it, post a link. I think that is rubbish.

It's illegal.

What transmits at 100 Hz that? I think you'd see more noise from power lines than anything else.

Given that a 1/4 wavelength antenna at 100Hz is 750km long, you must have a pretty big property.

Maybe it is the privet that keeps the EM signals in.

Yes they don't stop EM radiation nearly as well.

Nothing, as well as not knowing the law the OP knows nothing about RF transmissions either.

I meant  around 100Mhz  or so.

where I'm from the federal laws say its illegal, but the state laws point to it being legal. Even laser jammers are legal where I'm from.

Isn't it funny how the state of California legalized a federally band substance? Then told the federal government that law dose not apply here. That's because the states tell the federal government what to do its always been like that and it has to stay like that. Unless you want to be a slave.

The FM radio band is around 100MHz.

So lets say for sake of argument that it is legal to jam radio frequencies on your own property, which it's not, state laws are superseded in these situations.  For instance you can be arrested by a DEA agent in California for smoking marijuana even though is it legal there.  How are you gonna keep the jamming to just your property?  I'm gonna go ahead and say it would be very difficult to do if not impossible.

That being said if you wanna brake the law that's your prerogative.  By definition a radio jammer decreases the signal to noise ratio of a given broadcast.  You do this by increasing the noise as you have no control over the signal.  So you need a way to create noise and a way to transmit that noise.

The FCC regulations preempt ANY state attempt at regulating federally licensed communications systems.  You are being fed patently false information that your state/city/county/dog catcher/mayor or ANY other entity can regulate federally licensed communications systems.

As for your failed attempt at equating marijuana laws, I will just leave this here for your perusal http://www.sbsun.com/ci_22532373/authorities-raiding-multiple-san-bernardino-medical-marijuana-dispensaries

Good luck with your jammer.  I'll be watching the FCC enforcement logs for when you get your arse handed to you for using a jammer.  BTW, the fines START at $10,000 PLUS jail time.

You want to block FM radio from being received in your house. I assume that you just don't want your kids listning to that evil rock and roll music.
