Thank you for the post man! This is exactly what I've been looking for! Just so happened to have the capacitors laying around, Great addition! Look forward to the Proto board build!
I've been curious about where these might be used in public in and around my city. A few years back I lived in an area where, every time I walked past a specific section of the road past a certain set of houses on my way to pick up some groceries, my bluetooth would cut out. I first thought it was a coincidence but it happened every time I went past that particular spot, so I believe it was either one of the houses, or one of the small businesses nearby. I even changed my route a bit to avoid it because not only did the bluetooth drop, but I had to disconnect the ear buds and reboot the phone to get it working again; really stringe. I've noticed it happens in a few other public areas on my travels, in particular spots, and I've always wondered if somebody is using a jammer in that spot. Anyway, pretty interesting project.
Yes I can imagine this could be the case. I have a future project where this will have a small solar panel and battery so essentially it can run indefinitely until someone finds it . However there are lots of reasons for signal disturbances - you’d be surprised what the local law enforcement has and use regularly
@DivineZeal tourists? Local Mexicans..... Most Mexicans have these fetish for constant noise. Also using these on my neighbors, they decided to build a party place next to my house. (I'm Mexican btw)
Hi Divine! As you write, for Arduino IDE, it´s necessary to install "RF24" and "ezButton" libraries. I´ve found that is necessary also install "esp_bt" and "esp_wifi". I am correct? Do you recomend some especific link to do that? Thanks
can I use tantalum capacitor instead of electrolytic? and also I saw others connecting 2 capacitor one is 10uF electrolytic and one is 0.1uF ceramic capacitor in parallel on VCC na d GND did you try it? and also what is the best the single 10uF capacitor or parallel?
Hello, I would use electrolytic. And yes you can use in parallel, a 10uF and 0.1uF is recommended and normal practice for better performance. The way I show with one capacitor is easier for people to understand 👍, good luck
hey i just built one as per your video but for some reason i have to stablish a connection from my PC to make it work! if I close the COM connection on my PC stops working! what do you Suggest?
A few things, did you edit the code at all? Try an independent power source, disconnect from com port could also cut usb power . And also check your wiring just to make sure. But I’d try using from a different power source with correct cable
Thank you very much from Brazil, it worked with esp32d. First I assembled it without the capacitors because I didn't have any at the time and it still worked. What is the function of the capacitors please?
The capacitor is there to help with extra noise, decoupling for burst currents, and overall performance. If you use for extended periods it protects the device
Hello friend, thank you very much for sharing the project, I found it amazing and very sophisticated. I have a question, is this LNA adapter of the Nrf24l01 module required in this project? Thank you in advance for your attention and a big hug from Brazil :)
Hello, my friend! Thank you so much for your kind words and support-I’m glad you liked the project! 😊 To answer your question: the LNA adapter for the NRF24L01 module is not strictly required for all projects, but it depends on your specific needs. If you’re working on a project that requires long-range communication or improved signal strength, then using an NRF24L01 with an LNA can be very beneficial. However, for shorter-range applications, the standard NRF24L01 module without the LNA adapter should work just fine. Thanks for watching!
Thanks for watching! I haven’t tested the max range yet, and I’m waiting on new antennas, but current can get about 10-20yards through some walls so I’d imagine it’s pretty good
I’d suggest starting with an UNO board like the esp32-s3 UNO. It’s super easy to use and a great place to begin. There are tons of awesome tutorials and resources available on Adafruit Learn, especially for beginners. When it comes to soldering, start with simple projects and don’t be afraid to experiment and make mistakes. That’s all part of the learning process!
Hi, I have a M5stickc and nrf24 with custom firmware. So jamming is working there, but I want to try dual nrf24 as you did. So did I understand correctly that I need to connect second nrf24 in parallel to the first nrf24 to make it works and makes noise signal stronger?
@@DivineZealI realized it’s unreal to connect two nrf to m5stick because I have only 5 gpio pins +gnd and 3v. So all 5 pins are taken by one nrf, so there is now way to connect the second one, even if I share one spi bus then I anyway need to have two extra free pins. The only one way is to connect second nrf exactly to the same pins on m5stick. But I’m sure it wouldn’t work or there won’t be any difference between one nrf or two parallels nrf. What do you think?
do I have to use nrf240l like that, I bought ( NRF24L01 Ultra Long Range 2100M E01-ML01DP5 Ebyte 20dBm 2.4Ghz +PA+LNA), can I use this Sorry, my English is bad
Hey, looks great and thanks fot the video. bunch of questions: 1) is there any way to increase range? Any other antennas i could buy? Btw have you tested the range? 2) could this be done with an Arduino uno r3 or the Arduino mega2560 Thanks
Thanks for watching. 1)Yes of course, this is a very simple setup. However it is basic RF engineering as well. Meaning: NRF24L01+LNA+PA. LNA= Low noise amplifier. PA=Power amplifier. Bother of these have settings in the code. Stock antenna is I think 3dBi? Research what dBi even means. More is not always better. I recommend getting various 2.4ghz antennas to test for yourself. Range? Every test is different, trees, walls, all matter. I get 10-20M with walls, but how could you have my same test variables? You must try for yourself. Addons? Well this is RF engineering and you will need to test different amplifiers, and band pass filters which will create safe testing. The more you research the more you will understand, and then it is fun. Unfortunately I cannot share more, however I do have consultation services for more advanced topics
I am using 10uf 50V which is good enough. Anything more than 10uF is perfectly fine, but 100uf is overkill. If the capacitor size doesn’t bother you then go for it! Also a larger one may take longer to charge/discharge but I dunno if you’d notice
With walls it can do pretty good, but without walls I’m guessing 50M-100+ meters. Especially if you swap the stock antenna. These are same antennas used for rc drones… so as high as the sky lol
Can be increased with better antennas and good line of sight. Capacitors help decouple and with power surges, not too much range. I use 9-12dbi antennas from AliExpress. You can also make your own. Also if you are creative try adding more amplifiers and better power source
So far I’ve got about 10-20+ meters but that’s with walls. I have some different antennas I want to try with the nrf24 so should be way more. The nrf24 claims to have like 100-1000M
My friend, thank you very much. Id love to buy your PCB but its not showing up in the link. Do you have a suggestion for a portable power supply? I see a few options out there but wouldnt nind a professional suggestion. Something to run off 9v.
PCB is not available right now you can get the hardware files on my GitHub: github.com/dkyazzentwatwa/cypher-jammer/tree/main/hardware I would suggest a simple solution for portable: 18650 battery and a battery holder like this: a.aliexpress.com/_msAGRdZ

why does the prototype take 10uF 50V Capacitor and the final version with the printed board does not take?

Hi Divine! As you write, for Arduino IDE, it´s necessary to install "RF24" and "ezButton" libraries. I´ve found that is necessary also install "esp_bt" and "esp_wifi". I am correct? Do you recomend some especific link to do that? Thanks
Esp_wifi and esp_bt should be standard
Cool project! The two NRF modules is to get more RF power? Both NRF works in parallel with the same transmition signal? Thanks
Yes it’s for more power, and you can transmit at different channels for each Net or in parallel
If I use a long coaxial cable, will it still work?
Wondering, what is the range of them?
Stock not too far, a few meters, but you need to add amplifier and band pass filters for best performance
@@DivineZeal what amplifier and filters ?
I think it'd be helpful to talk about the circuit and code and how this works.
Yes I am going to make a more in-depth video. I have the custom pcbs coming next week!

@DivineZeal thanks did you try the nrf24 of ebyte the green one they said that this is better than the black nrf24 in terms of range?
Hi, I have the same equipment and it works, but it has to be very close. What is the range at a distance?

Can I use esp8266 nodeMCU instead of esp32
No just be esp32! Esp8266 is much weaker
Help, I did everything like in github, the code compiled right, but it does absolutely nothing
Does your serial console say HP & SP started??
@@DivineZeal I don't think so. I got it to barely work, but now it doesn't do anything at all anymore.

@DivineZeal thanks!
what's the range of this?
10-30+ meters depends on your antennas. I don’t use the stock antennas

can i use display in this ESP?
Yes but currently not for this project

Yes it is best not to cross antennas. If using multiple, the nRFs can share the same SPI bus, just have different CS + CSN pins
@@DivineZealI realized it’s unreal to connect two nrf to m5stick because I have only 5 gpio pins +gnd and 3v.

Whats the range?
Depends on your setup, this is most basic and I get about 10m with walls
What is the range on this device?
The range for me is least 30 meters, however I use stronger antennas than the stock, about 9dBi
Could you post the link to the project with just one NRF24 antenna. + ESP32
You can use the non DUAL .ino files here

Is the capacitor effect the range? Becuz i use 50v and 47uf and seem like it work only 1-2 meter
You need better antennas. Find 9+ dBi 2.4ghz antennas
does it disconnect the device? and what does it do to wifi?
It stops the device for transmitting data, doesn’t disconnect. You change the channels in code to target WiFi or Bluetooth
Can you make a tutorial for the jumper cable
Yes I am going to make a more detailed video with the cables and soldering!
do I have to use nrf240l like that, I bought ( NRF24L01 Ultra Long Range 2100M E01-ML01DP5 Ebyte 20dBm 2.4Ghz +PA+LNA), can I use this
Sorry, my English is bad
Yes it will work. If it doesn’t work good you will have to add a 10uF 50V capacitor like I did
@@DivineZeal
terimakasih banyak, saya sudah berhasil membuatnya
Will the 2.4 frequency also interfere? (WiFi)
Yes WiFi is channels 1-14, Bluetooth 1-80, and drones 1-125
Thank you!
You are very welcome!
Can I do with esp8266 and nrf
esp8266 doesnt have bt
Can i use esp32 wroom 32d instead of 32e?
And without amplifier and with 9dbi how long can it support?
Yes, of course. You need amplifier though for best results. You can even source your or stronger amplifier
@DivineZeal thanks for the reply
Is it possible to use 3?
Yes I have a project with 3 coming really soon but it is more complex. I have the custom pcb that will be easy for people to make
@@DivineZeal The problem with me is that none of these companies makes deliveries to my state
