is there any other transistor you could substitute for the pn2222

Comment Authorbr1 / Apr 12, 2008

The pn2222 can be easly found at www.amazing1.com, they also sell the variable capacitor, they use a 6-35pF variablecapacitor. They also sell the full kit. By the way were would you put the white noise circuit?

Comment Author / Apr 30, 2008

what range of frequencies will this work for? Could i push it to arouns 3Mhz? Thanks

Comment AuthorRich / May 3, 2008

I like cheese

Comment Authornone / Apr 18, 2008

like say could you substitute the pn2222 for 2n4401 or the 2n4403 ????

Comment AuthorDan / May 20, 2008

I couldn't find all the parts I needed so I made some substitutions: 10K + 4.7K instead of a 15K resistor 7pf cap instead of a 6pftrimmer cap - NO CLUE WHAT VALUE 2n2222 instead of pn2222 However, mine my circuit doesn't seem to be working! Ithink it's because I have no clue what range my trimmer cap is. Could someone suggest a fixed value capacitor to target afrequency in the FM band? Thanks!

Comment Authorschutze / May 31, 2008

what variable capacitor do I use to jam fm and tv? what does #16 wire mean?

Comment Authorapk / Jun 12, 2008

I like this.Is it applicable to loudspeaker jamming? If anyone ideas about loudspeaker jammer plz help. could you mail mecircuit or idea if u have abt loudspeaker jammer? Thanx

Comment Authoranonymous / Jun 13, 2008

Hie is it possible to use the same circuit for high frequency jamming?

Comment AuthorJammin' with Bob / Jul 12, 2008

Loudspeaker jammin? Tell me more. how to, where to and how far? I need about 150 meters of reach.

Comment AuthorUnknown / Jul 18, 2008

How can we increase the frequency up to 900-1800 MHZ?????

Comment Authorfaize / Jul 22, 2008

I think that is incomlete circuit there is input and out put not defined...........

Comment AuthorNick / Jul 22, 2008

Is it possible to use this to jam cb freq 27mhz to say 27.900mhz...Basically i am after a small jammer to hide close to an idiotso he cant hear anything hoping that he gives up CB.....Thanks

Comment AuthorLinas / Oct 25, 2009

who can help me,i need 900/1800 Mobile Phone Jammers schematic,thank for help :)

Comment AuthorLoudspeaker nuisance / Sep 13, 2008

Hi, more than TV or FM jammer, what we need is a loud speaker jammer. Some stupids play old bring songs often in thestreets in the name of functions and the volume is ear deafening. Plz come up with a loud speaker jammer which reallyworks...

Comment Authortrasistor replacment / May 25, 2009

can i used another type of transistor instead of pn2222?

Comment AuthorhkBattousai / Aug 11, 2009

Poor schematics. Some circuit elements are not defined. There is no specification (Output spectrum & waveform, etc) for thecircuit.

Comment Authorgiueseppe / Jul 31, 2009

how what is radio tv! I think my cicrcit make work but my light go off? Could maybe used 1N34 for 2pn2222!

Comment Author440herz / Aug 13, 2009

'loudspeaker jammer' LOL...sure, and after I send you a schematic for loudspeaker jamming I suppose you'll want the circuitthat turns taffic lights green as you approach, or the lawnmower jammer that shuts down petrol lawnmowers from up to 50

meteres. Sorry but I am not giving out that information.

Comment Authorsos / Nov 24, 2009

avariable capacitor from 5-45pf and when we want to jamming on TV we must turn capacitor

Comment AuthorUSSR / Aug 19, 2009

"This device can be very illegall" - why? This is tipysh oscillator shematic and it is as illegal as knife on your kitchen! Samecircuit you can find in old FM radios.

Comment Authorendorfun / Aug 22, 2009

I loud speaker jammer? I think the only way you are going to get an rf type jamming device to jam a loud speaker is not likely

to happen unless the loud speaker source is a radio broadcast which this device will use anyway. Jamming a wired speaker isnot possible with any RF device of any wattage!

Comment AuthorEndorfun / Aug 22, 2009

As for the antenae. I silver soldered a 20 gauge copper wire of approx 25 cm to the fourth winding of the coil, and it workedrather well. Any wire really between 12 and 30 cm attached anywhere on the coil will do.

Comment Authornemo / Sep 26, 2009

Anyone knows what "#16 wire" maens? 1.6mm or 0.16mm or something else?

Comment AuthorJohnny English / Nov 24, 2009

why have we used capacitors here? isn't it used to eliminate the DC input? as i've used in my FM transmitter circuit? i havemade this circuit at home, don't know the exact frequency at which it operates!

Comment AuthorGermanico / Dec 4, 2009

#16 wire means wire that is at 16 in the AWG, the american wire gauge table. Google it up. It would be around 1.2 mm.

Comment AuthormR.HornY / Nov 10, 2009

This circuit is incommensurable. and i believe have short-range out and simple. I need a REAL!


4/9

Comment AuthorSaqib Ahmed / Dec 8, 2009

BC 547 is a good substitution for PN 2222. #16 wire means 16 gague wire. I think it will be SWG i.e, Standard wiresystem.Instead of 6 pF 4.7 pF performs best. 10 K instead of 15K and 4.7 K instead of 3.9K will give best results. Remainingcircuit is quite good to introduce with wave jamming.

Comment Authorzeeshan aslam / Jan 8, 2010

can any one help me by sending me the theory about this circuit i mean the principles and basic concepts about the jammer

and also a little description abt the function of components used in the ckt... my email id is [email protected] plz dorply as soon as possible

Comment Authorsignalknight01 / Jan 19, 2010

you can order cell phone jammer online from www.???.com ,if you have any question about cell phone jammer,you can talkwith workers online too

Comment AuthorOmni_squirrel / Mar 12, 2010

Very simple, constructed it, and successfully jammed two radios in my electronics class! Have yet to try it on "TV" but itdefinitely works as a radio jammer! Thanks for the schem!

Comment Authorvk6fssa(swastik) / May 2, 2010

can this be used for other frequency bands if yes how (bit new to electronics myself 13 years old)

Comment Authorsalman / Mar 21, 2010

plz tell me what frequency range is best compatible with this circuit?ASAP

Comment Authorsurojit / May 18, 2010

whats that #16wire can some one plz tell me tha diameter of the wire i will be very thank full to that one . Thanks.

Comment Authoranyone / Jun 21, 2010

ive got a great idea... instead of jamming one station, why not jam all! romove the 3.9k resistor and replace the 15k with a 10k,

i used a 0-180 Vcap. tune to 107.3 and tune it till you hear the most interference without blocking it, then change the stationand you will hear nothing but fuss!

Comment Authorpete / Sep 11, 2010

Has anyone put a frequency counter on the output of this? I can only get mine to a max frequency of 80mhz - it still jams FMradio when I tune it, I guess by harmonics.

Comment Authorwhatever/ Aug 19, 2010

#16wire is 1mm2 wire

Comment Authorasdf/ Aug 14, 2010

Can anyone build one for me? I need to jam all FM. My neighbor is driving my baby crazy with the high volume and I need thebaby to sleep. Thank you very much.

Electronic Mosquito RepellentJuly 29, 2010P. Marian4 comments

This electronic mosquitoes repellent circuit is easy to build but is kind of hard to adjust on the exact sound

frequency which will reppel the mosquitoes. With frequencies between 2 KHz and 2.5 KHz which mimic male

mosquitoes buzz, it seems you can get the best effect.

Read more: http://electroschematics.com/5930/electronic-mosquitoes-repellent/#ixzz1AWa6pyDg

But sometimes you may need to readjust the potentiometer so the freq. be as high as 10 KHz. Anyway, the fact is

that you may need to make a lot of experiments until get the best result. You can read this article about insects

and how do they react to ultrasounds Ultrasound and Insects.

You may add an audio amplifier but dont forget to connect the small filter (damper) between the electronicmosquito repellent and the amplifier.

Don't like your little brother's TV channel selection? Hate the volume your wife sets the

stereo at? Want to just annoy someone? This circuit does all that and more by jamming

most IR remote signals. The circuit releases a flood of pulsing IR light that confuses the

reciever by corrupting the data stream.

Notes

1. Email Carl with questions, comments, etc.2. You may need to adjust the value of R3 for the right frequency. A pot can be

used.3. You may only need one IR LED.4. It goes without saying that this circuit should be used with descretion.5. The value of R5 depends on your supply voltage and LED. For a standard

4.5V supply and standard IR LED, use 22 Ohm as specified on the parts

list. This forum topic covers this resistor as well as a few other issues withthe circuit.
