@@justanengineer5599 I just have the exact same module as you and it didn’t really work out, I was thinking maybe the antenna wasn’t connected to the appropriate hole and couldn’t create a strong enough signal, is it possible to Build something with a stronger antenna perhaps? Btw, thank you for your reply!
Look at github page there is diagram how to connect github.com/mcore1976/jammer/blob/master/JAMMER-SCHEMATIC.png If you don't want to solder buy a "breadboard" or "protoboard" and connect ATTINY & FS1000A using colour wires and pins
The code will fit to ATTINY85 (digispark). The only thing you need to pay attention is CPU clock. On my ATTINY13 the clock was 8MHz with division to 1MHz, on Digispark there is 16MHz. The code will still work but the pulses will differ x2 in length. For the PCB - you have to connect"PB2" pin of ATTINY85 ( PIN #7 on Digispark) to Data on transmitter PCB.
hello , where did u get that solid copper wire which acts as an antenna ? i use stranded wires but they are much flexible and therefore it doesnt stand straight enough .. did u get it from any electronics component like an old pc ? because most devices use stranded wires
Yes, the green wire is 'whip antenna'. This one should have length adjusted to radio frequency of FS1000A module using this calculator : www.csgnetwork.com/antennagenericfreqlencalc.html For example for 433MHz it will be 16.5 cm length of green wire. For 315 MHz it will be 8.91inch / 22.6 cm
Hi, I have a problem with sniffing a car remote key output, my receiver is a RXB35 433MHz module, and my remote is also 433MHz, I tried lots of arduino libraries which people normally use to sniff rf remote codes but I get nothing on my output. do you have any ideas that why its not working?
Hi, the RXB35 is ASK (Amplitude Shift Keying) Superheterodyne receiver - so it can decode Amplitude modulated signals (pulses). In theory you should be able to receive on DO (Data Out) and SCLK (clock) information about an amplitude. The point is that it may not be exactly tuned to the frequency of car remote transmission. For car keys I would suggest to use ordinary RTLSDR usb dongle to see the base frequency of the car key (as I am doing on my videos). Then you can record WAV file from modulated signal with SDRSharp or SDRTouch and further analyze it. After you done it you can create a transmitter that sends same waveform using for example CC1101 chip. CC1101 can be programmed to work on particular frequency. You can always use already available products like Yardstick ONE for sending over the air.
Hi. You simply need to attach more modules FS1000A. Also better antennas could help (dipole for example). Be careful whem applying higher voltage to the unit. The microcontroler can work up to 5.5V only. You would need to provide higher VCC only to FS1000A while MCU voltage should remain 5V
i have 2 questions: 1.what type of connector is the black one (with three holes) in which u put the 3 pins of fs1000a? how much wires does it have because its difficult to see on the angle u showed in the video. 2-what type of soldiering iron do you use?what company is that because i want to order one online but im afraid i get a bad quality soldering kit. the project is very interesting indeed.
Hi Denis, 1) the connector I am using is 0,1 inch / 2.54mm - single row female header - there is plenty of them on ebay f.ex., but you can always solder cables directly to the FS1000A board ( 3 connections - GND, VCC and DATA). I do recommend to buy some 0.5mm color wires (on Amazon) and solder them directly between ATTINY chip and FS1000A. 2) I am using FERM soldering station SGM1013 with their solder wires ( you can buy it on Amazon ) it is about 30USD
Hey there , i tried to jamm my friend’s car and it did not work .. it is an audi a4 2017 year ,i checked his keyfob by using sdr sharp and there i saw that when i clicked the lock/unlock button it generated signals at 433,525 mhz ..and technically this frequency is jammed by your device when it is turned on , but when i try to block the signal i cant do it .. the car still gets the signal .. this is very strange .. do newer cars use keyfobs with dual frequency or something .. because i am very confused when i see the. sdr sharp because it tells me i actually have enough power to block the car from receiving the signal from keyfob .. thanks
Hi, the newest cars may use different modulation schemes with code correction. The jammer is most effective when key frequency is 433,92 so it may not work so well for your key. You may also try to send signals from 2 or 3 such jammers at the same time for stronger signal.
well I do not understand your question. Use better translator. The point is to connect the cables as on this picture github.com/mcore1976/jammer/blob/master/JAMMER-SCHEMATIC.png it is not hard to do it. If you dont know how to solder ask someone for help
thanks for the video , I bought f1000a (315 mhz) and ATtiny13a , connected all , like you show on schematics , but it's didn't work , I looked at scop and it's no signal from pin 7 of tiny13 coming out , any suggestion ? (I have a lot of experience , so I checked all schematics 4-5 times )
looks like you need to upload the program first... It doesn't work if the chip isn't flashed with the code... have you watched this video th-cam.com/video/7klgyNzZ2TI/w-d-xo.html ?
Or do we Just have to connect Attiny13 with USPasp and run ./compileattiny and after running that command Disconnect it from usbasp and connect it to FS1000A and power it. PS: Plz do reply
You have to use avr-gcc environment (not the Arduino IDE) on Windows or Linux and usbasp programmer connected to 5 pins of the attiny with some wires. To upload the code run compileattiny script from command line (cmd in windows or terminal in linux). It is shown on my other video with digital thermometer how to do it. Check my other video th-cam.com/video/r6nF1iJ2r-M/w-d-xo.html

Yes you can use ATTINY85, the only thing is you have to change delay function in the code f.ex. : Example 1 instead of : // Delay 5 cycles, 5us at 1 MHz asm volatile ( " lpm" " " " rjmp 1f" " " "1:" " " ); put : _delay_us(5); // ARDUINO UNO lub DIGISPARK Example 2 : Instead of : // Delay 20 000 cycles // 20ms at 1 MHz asm volatile ( " ldi r18, 26" " " " ldi r19, 249" " " "1: dec r19" " " " brne 1b" " " " dec r18" " " " brne 1b" " " ); put in the code : _delay_ms (20);

You buy FS1000A tuned to this frequency 315MHz and it's done. As simple as that. The cost of FS1000A 315MHz is 1 USD on www.aliexpress.com
@@justanengineer5599 I got some of the ttiny13 chips off ebay win day got here I opened them up to find out that they are not the same ones you have in the video day are ttiny 13 but not the same size as the one you have day are super small too small I think think you can point me in the right direction or do you think I can use them
Hi do you use a voltage regulator in this battery holder?
is it 4x aa batterie or 3x ?
there are 3x AA battery inside AFAIR
Hi friend, can It work for 24/7?
Yes of course
@@justanengineer5599 Hello brother, do you think that if I connect the 3 gpio ports of the rf jammer to the gpio ports of a raspberry pi it will be able to work and give it current without problems or not? or should I buy a switch with button like yours in your video? Thank you
i got the sdr dongle but it came without antenna,can you provide me a link where i can buy the antenna that u used in this video?
Hi, search for "SMA male telescopic antenna" on www.aliexpress.com or www.banggood.com or www.gearbest.com. You can always check www.amazon.com. Ensure that the connector fits first with the seller.
Nice video
Fajne filmiki instruktażowe ,
czy mógł bym poprosić kontakt
do ciebie .
Kontakt jest na GitHub.
@@justanengineer5599 No nie mogę Pana znaleźć
Link do strony github jest w opisie filmu. Na github w kazdym projekcie w pliku main.c jest moj email
Sprawdz w pozostalych projektach na mojej stronie github. W pierwszych kilku linijkach kodu main.c jest moj email.
Hello i just wanted you to know that i have reprogrammed the chip step by step like you did in the video you have send me except for the 'vi compileattiny' because i do not think i have that crystal since i am doing the 2$ car jammer project. Tonight i will test it and let you know if it works. For the antenna i used a 16.5 CM earth cable 2,5 mm2 (green yellow cable). If its possible id like to have your whatsapp or wickr for faster contact and sharing pictures. Thank you alot for your help, your a hero!
Hi. good luck ! Good that you didn't modify 'compileattiny" script because changing values there is needed only when using quartz oscilaltor (XTAL).
@@justanengineer5599 is there any way to have faster contact with you? maybe i can share you the project and some pictures. after doing everything right it still does not work.
HI look into the first few lines of main.c files on my GitHub projects (not the jammer but others). There is my email there within first lines of main.c Maybe your FS1000A is not well built (may be a cheap copy f.ex. can have single coil ) or the transmitting frequency of this module is different than the car keys you want to jam...

Not 100 legal
yes and no. If used to protect your own car from "copied" key senders then it's used for good purpose
