I made similar tv jammers in the 70's, got into a lot of trouble as well! this is just a "dirty" square wave oscillator that jams "dc to daylight" like the old spark transmitters, jams all frequencies, but as commented below, limited range.
I built a police radio jammer in a matchbox back in the early 80s using transistors for the oscillator rather than a 555. I tuned it by sitting in the coffee shop by some cops and used a flattened toothpick to adjust the Fq through a hole in the box above the PCB pot until their radio just went dead silent. 555/556/558 are one of the most useful ICs on the market though. I also built a super bright flashlight with a 555 to switch an LED on and off with 5vdc from the output pin so fast it looked like a solid beam but too fast to burn out the LED. Good old days.

It would work with modern phone, too. It creates a static signal, that is stronger than the cell signal and therefore blocks it. I haven‘t tried out the exact circuit, but i‘ve used a Raspberry Pi as a signal generator and it blocked the signal of my smartphone (however if it just jams the signal on a single frequency, most devices will just use another frequency or EDGE/GSM).
Great Project !, Now we need a 3G and 4G LTE version of this jammer. I would totally use one of these to mess with my sister, she always has terrible reception...LOL.

The fun part is making your own circuit board with a Dremel tool and working from the blueprint . The range on this version has better range than anticipated .
A buddy of mine years ago had one he got off Ebay and would love to walk around in a crowd with this in his pocket. Any call within ten feet would freeze up and loose audio or drop. Was funny, but damn I always told him if someone figures it out you are toast. They don't sell these anymore.

How significant does the guage of wire determine the amount of inductance of an air-wound coil if all other parameters remain constant? L= (d^2 * n^2)/(18d+40l) where: L is inductance in micro Henrys, d is coil diameter in inches, l is coil length in inches, and n is number of turns.
Thi guy is a liar!!! Not only is the 24 AWG wrong as you say, also the pc board when he shows you how he assembles it you can see there is no resistor for the LED the when he flips it over, oh magic you have the resistor. Also the pcb in his link has a mistake where the led goes... you have to modify it. I CAN NOT UNDERSTAND THESE GUYS!!!
A hairdryer is basically a fan (aka a motor with blades) and a heating element. The motor uses coils to rotate, which emits a fluctuating magnetic field. If you're close enough, the magnetic field will overpower the signal, but only on the frequencies it emits ( that would be the rpm of the motor * the number of poles of the motor, and multiples of this frequency, plus probably the 50 or 60 hz from the power grid)

to increase range you would need a Q2 with a bit more power, you could also reduce the value of R4 slightly to increase range, but if you go to low it will burn the transistor
@@goran-is6zr you should study electromagnetic waves to learn this stuff but its generally common sense to get more efficiency you should get a high output for any electronic device. in this case resistor protects some of the elements in the circuits while loads the circuit a bit which causes range to decrease. you can start learning with basic circuit theory and electronic devices like transistors, diodes, op amps and so on, after that study electromagnetic field&wave theory in order to comperhend the basic logic of antennas.

Yeah I never really understood this, is it a frequency multiplier? Or is it that the higher harmonics from this specific oscillator creates noise for the base band of 2/3/4G signals?
Perhaps the fact of being a square signal allows some of its components in high frequency to generate interference. You have to do FFT with an oscilloscope.

The oscillator works at 2.5 MHz true?
It is interesting that it disturbs the receiver even though it works on GHz frequencies.

No, the maximum frequency of the ne555 is around 500kHz, but the electromagnetic field can still disturb the cell phone signal, I think
Yeah I never really understood this, is it a frequency multiplier? Or is it that the higher harmonics from this specific oscillator creates noise for the base band of 2/3/4G signals?
IMO the oscillator is L1/L2 and varcap 30pf, the NE555 only excites this oscillator from time to time, its own frequency doesn't matter

Your schematic is incorrect; the schematic shows R3 and R5 between VCC and GND without a connection "dot" to the base of Q1 and cathode of C1. However the PCB layout mask clearly shows those points connected! This would certainly be an issue for anyone breadboarding or perfboarding this circuit without your PCB layout.
hello can you please provide the right circuit diagram for this as i will be running the circuit simulation via multism. hope you can see this sir
Most of the people watching this video scroll down to comments to see if it really work
And the effective range is? ... Unknown. And the battery lifetime is? ... Not important. I'm so very happy I know how to put a component onto PCB. Yes, the music was .....
please send me link of pcb which Download in phone
coils has different count of threads as described :D
I dont understand why you soldered the wires to the header pins. Also range on this is what 3 inches maybe.. whats the point of this.
Proof of concept I guess
How the hell do people know what to do with all these wires and components. I'm so confused
Creative science: Let's make signal jammer
Vodafone,Idea : Wait! we don't do that here!
Hey buddy ware did you get all of the parts for it
From shop and the plate he 3d printed
What Frequency range does it work on??
And is it just for 2G?
Probably 850 and/or 900 MHz. Because of that, it probably would also work on low band 4G and 5G.
Hi bro
Transfer this Signal jammer
You will make and give me for money
Very nice brother
Yes I will give you this project but it's very charge fully project you are interested take this project
bob an vagen
@@TechnicalYarana how much?
Dm me brother
@@samproductions7 yes bro
You used old nokia phone to demonstrate but does that jammer work in morden mobile like *red mi* and *Lenovo*😃😃😃
Pls answer
Remove the 555 and keep the Transistor. Then you have FM radio Jammer

@@seyedmahdiqazanfaree5234 depends on how the two pc's are connected to each other.
I like this one... So subscribe your chanal.. All the best...
thanks bro :)
