Radio sniffer смотреть последние обновления за сегодня на .
More experiments with the 555 voltage controlled oscillator. This time connected to a diode and short antenna to detect the presence of RF. It can detect a 1w VHF/UHF handheld from about 2 or 3 metres away. Useful for testing radio gear, antenna directivity or for ARDF/foxhunting.

This is the third in a series of videos following my efforts to track down a source of local QRM / Radio Interference. Following the build of a successful direction finding loop, in this video I build an RF sniffer probe and track down the source of QRM and finally eliminate it! The sniffer is for pointing to suspect items up close when perhaps the loop might be overwhelmed or non-directional if say inside a building. Here is the link to the first video detailing the local area power-cut: 🤍 And the second video showing the build and successful use of a direction finding loop: 🤍 I forgot to say in the video, the end result is me buying a free replacement, and hats-off to the homeowner for helping me out!

When you build a tiny transmitter, the hardest part can be finding the correct operating frequency but when the lake of received signal is associated with the uncertainty of whether or not the transmitter is working at all a little bit of help is useful, to help establish that there is at least some life in the circuit I've come up with a simple little test circuit that is easy to make and it should be helpful to you. You can also use this device to show whether or not the 'local oscillator' in a domestic radio is running. There's nothing critical in the probe, its simply a matter of detecting the presence of an AC or RF magnetic field. An AC voltage is developed across the coil windings, this voltage is rectified by the diode and the resulting DC voltage is used to pump up a small capacitor. The voltage developed across the capacitor can then be measured and read with a digital DC volt meter. Things you should know... The diode needs to have a low forward volt drop, say 0.3V or less rather than 0.7V Any germanium diode should be OK, like you'd use in a crystal set receiver will give the best results. I used a BAT85 the spec sheet says the Fv is 400mV but I measured it as 227mV (which is good) The coil could have 2 turns or 100 turns, work with whatever suits your application. Essentially the pickup coil is the secondary of a transformer and so long as they all couple with the primary (the transmitter's) coil then they should add voltage. Again the capacitor could easily be anything from 0.02uf to 0.5uf or even a wider range than that, I simply used what come to hand. The last point is, you do need to use a digital volt meter, digital meters generally have a very high input impedance when compared to moving coil meters. The circuit can drive a very sensitive (50 microamp) moving coil meter but I figure folks are more likely to have a digital meter these days. I hope you find this interesting and hopefully helpful, if you do please let me know as I like to know I'm uploading stuff that folks like. Thanks for watching. Kind Regards ...

RF Sniffer - a very low cost Radio Sniffer you can build at home 🤍 Some people asked me to provide the schematic, I just made it for you and will be found at this link: 🤍 Here is a very low cost RF Sniffing circuit you can build at home by using Darlington transistor, Germanium diode, 220 ohm resistor, an LED, a 10 uH inductor (or close value), a 10 nF cap, a 10 to 15 cm wire, 3 VDC battery and an optional 3 VDC sounding element. It is basically a parallel LC circuit (MAX impedance at resonant frequency) where the RF signal is fed to the antenna then to the GE diode then to the base od the Darlington transistor. The Emitter of transistor is connected to ground and collector connects to the low ohm resistor (in parallel with optional sound element) and the LED then connects to the + rail of 3 VCD. It is that simple, and works perfect as seen on this video. If you want to know the Darlington transistor I am using, it is 2N5307. I got a bunch of them at less than a buck to use in quick prototyping such as this prototype. You can use an inductor that is around this value and then you change the frequency you tune to. Remember that an LC circuit has MAX impedance at resonance and thus will enable MAX delivery of the received signal from antenna to the Base of transistor via the GE Diode. You can add a transistor gain stage after picking the signal from the Collector of Darlington transistor and thus multiply the gain or add more sensitivity into the circuit and thus enabling signal sniffing at further distances. Refer to electronics books on how to DC bias those transistors - it is simple. Learn more about how this circuit works ... sorry I don't have schematic because those kinds of circuits don't need schematics, I have done many RF circuits that this front end RF design became common sense. Sensor detects motion and sends signal wirelessly to reporting receiver device: 🤍 Hope you enjoy this video. Firas

DVB-T dongles based on the Realtek RTL2832U can be used as a cheap SDR, since the chip allows transferring the raw I/Q samples to the host, which is officially used for DAB/DAB+/FM demodulation. The possibility of this has been discovered by Eric Fry History and Discovery of RTLSDR. Antti Palosaari has not been involved in development of rtl-sdr. The RTL-SDR software defined radio can be used to analyze cellular phone GSM signals, using Linux based tools Airprobe and Wireshark. The rtl-sdr combined with SDRSharp, and a POCSAG/Flex capable decoding application can be used to decode pager messages. With this setup you can receive pager messages from all pager users on the system. With the right additional hardware, the rtl-sdr can be used as a super cheap radio telescope for radio astronomy experiment סורק תדרים משטרה אמבולנס מכבי אש מטוסים ועוד..

This video describes a simple RF demodulator / detector probe that you can use with your DMM or oscilloscope to measure the relative amplitude of an RF signal in your circuit. It is very useful for tuning or adjusting IF stages during alignment, filter responses, peaking RF circuits, and examining amplitude modulation characteristics. The video describes the circuit and its operation, and demonstrates how to use it and the typical results you'll achieve. It uses a pair of 1N34A Germanium diodes, but could also be built with other low capacitance, low bias diodes. Notes from the video can be found here: 🤍

Wireless Alarm 433Mhz 866Mhz jammer and sniffer 🤍 A Baofeng GT-5R radio can be used to jam home alarm systems. Many home alarms operate wirelessly (window, door, hallway sensors) on either 433Mhz or 866Mhz. This cheap, $25 radio can transmit on 43Mhzwhile doing so it also sends out a frequency at double the Mhz...which just happens to be 866Mhz. You can see the little burbling waves of the background 433Mhz devices...and then see them all drowned out by the 5 Watt radio. Now, you have to remember that 5W is way, way more powerful than what all the little infrared wall mounted sensors and cameras are putting out, so the radio easily drowns out pretty much the entire alarm network (and all the neighbors too). This radio receives 144Mhz-148Mhz, FM radio and it can also TRANSMIT on 420MHz-450Mhz. This was tested on an installed alarm system and WORKED. Holding down the transmit button allows you to open doors/windows and walk past room/hallway sensors without setting off the alarm or even getting an interference warning from the alarm main box! The sniffer is an RTL-SDR dongle, hooked to a MooElec Ham it up box running into a laptop (running linux mint, but it works on Windows). The antenna is a simple telescoping AM/FM type antenna and the antenna on the transmitter is the cheapie one that came with it. The software to see all this awesomeness was CubicSDR with basically the default settings.

We will build a sensor which - Monitors its environment and detect all smartphones with enabled Wi-Fi functionality. This is possible because all Smartphones regularly send messages to detect networks around them - Uses the signal strength to detect how far away this smartphone is - Adds all newly detected smartphones to an internal database - Regularly connects to an MQTT server and sends the list of the detected devices to our home-automation or alarm system Theoretically it should be able to detect our presenceas well as the appearance of undesirable intruders. Let’s start to find out if this is possible. And we will learn a few interesting things about privacy in the age of Smartphones.
