This handy mobile bug or cell phone detector, pocket-size mobile transmission detector or sniffer can sense the presence of an activated mobile cellphone from a distance of one and-a-half metres.
The circuit can detect both the incoming and outgoing calls, SMS and video transmission even if the mobile phone is kept in the silent mode. An ordinary RF detector using tuned LC circuits is not suitable for detecting signals in the GHz frequency band used in mobile phones.
Here the circuit uses a 0.22?F disk capacitor (C3) to capture the RF signals from the mobile phone. Op-amp IC CA3130 (IC1) is used in the circuit as a current-to-voltage converter with capacitor C3 connected between its inverting and non-inverting inputs.
Capacitor C3 in conjunction with the lead inductance acts as a transmission line that intercepts the signals from the mobile phone. Capacitor C4 along with high-value resistor R1 keeps the non-inverting input stable for easy swing of the output to high state. When the cell phone detector signal is detected by C3, the output of IC1 becomes high and low alternately according to the frequency of the signal as indicated by LED1.
Assemble the cell phone detector circuit on a general purpose PCB as compact as possible and enclose in a small box like junk mobile case.
Use the miniature 12V battery of a remote control and a small buzzer to make the gadget pocket-size.
Hi I completed this project on pcb but its not working, I tried with 9 volts power supply, cam anyone tell mw , what will be the problume, pl contact me my e mail. Electrosensitivity, like any chronic disease brings with it its share of hardship and suffering. Steve spent more than 40 hours a week building power microwave amplifiers for the base stations of cell towers.
Desperate to determine whether a link existed between her husbands exposure and his illness, his wife Carleigh Cooper began researching the effects of cell phone radiation on the human body. It is precisely these subtle adverse effects that we all, given that pretty much everyone on the planet is exposed in some way to EMFs, need to keep our eye on. Gary: “Our guest’s late husband, for 16 years, tested and repaired the power microwave amplifiers for the base stations of cell towers. Nobody wants to talk about this including those of us who use the phones because we don’t want to put our phones down.
I think one of the deceptions is that you are not being told what symptoms you need to look for prior to ever developing cancer. There is still confusion in the minds of many as to the adverse health effects of cell phone radiation. Looking at data from 1973-1988, a study was carried out in San Francisco to investigate how the risk of cancer was associated with the distance from the Surto cell phone tower that was built in the 1970’s.
The study found that the cancer risk increased 10 fold for residents who lived less than 2kms from the tower.
A study done in Salzburg, Austria investigated the relationship between a tower built in 1984 and increased cancer risk. In Germany, a study was conducted to access the relative risk to cancers for residents who lived near a tower built in 1993 in Naila. In Netanya Israel, a study investigated the increased risk to cancer from a tower built in 1996 for men and women. A meta-analysis of studies data on childhood Leukemia published in 2000 found that children were 2 times more likely to have leukemia if they had been exposed to more than 0.4 µT (microtesla) of electromagnetic frequencies. The interphone study was published in 2010 and was aimed at accessing the health effects of cell phone use. Data published on average minutes of cell phone use per month in USA shows that it takes colored people on average 6 years to accumulate more than 1640 hours of cell phone use and enter the “high risk group.” It takes Hispanics 10 years, Asians 12 years and Whites 13 years to accumulate 1640 hrs of cell phone use.
It takes on average 40 to 50 years from when you start smoking before you’re diagnosed with lung cancer, 30-40 years from exposure to asbestos before you are diagnosed with mesothelioma, and 20 to 30 years from exposure to occupational dyes before you’re diagnosed with bladder tumors.
A study published in 2009 by Moskowitz et al in the Journal of Clinical Oncology investigated the research bias in blinded and un-blinded studies. Another meta-analysis published in 2005 investigated the “funding bias” between industrial and independently funded research.
Images of the brain of a 5 year old, 10 year old and an adult reveal that children absorb far more RF radiation from cell phones than adults.
Data collected in 2000-2004 from different States in the US revealed that there was a strong positive correlation between the number of cell phone subscriptions and the incidence of brain tumors in the States. A study was conducted in 2003 to investigate how SAR (Specific Absorption Rate) affected the brain barrier leakage in rats. In January 2008, a study done on a group of men undergoing infertility evaluation that looked at the relationship between number of hours the men had a cell phone and their fertility. Senator Mark Leno: “I am Senator Mark Leno and I appreciate you joining us as we introduce this bill. In 1992 the Federal Communications Commission adopted the industry designed standards of the Institute of Electrical and Electronic Engineers, the IEEE, and the standard is that the maximum level of radiation emitted from a cell phone and absorbed by the human brain and body would be the Specific Absorption Rate.
Many recent studies in Denmark, Finland, Norway, Sweden and England have shown serious concerns and health risks in both extended use and especially for children. As a result of all this new information there were congregational hearings held in September of 2008.
And then I just want to share with you a couple of statements made by the United States National Cancer institute and this was updated in September 2009. Given the power of the cell phone lobby there is every chance that the Bill will be scuppered. But whether it is this Bill or another one I have high hopes that legislation along the lines of SB932 to make users aware of the dangers of cell phone radiation before they buy will find its way on to the statute books. In the US the Federal Communications Commission (FCC) has established maximum exposure limits to limit the health effects from this radiation.
Cell phone users who put their phones in their pockets or hold their cell phones directly against their bodies are very likely to exceed the established safe levels.
This fact, however, is typically buried deep in the cell phone’s user manual and sealed in the retail packaging. Senate Bill 932 requires that the safety information currently included in cell phone user manuals be posted on point-of-purchase display materials and on the manufacturer’s website.
Honeybees, of course, pollinate about a third of all the food consumed by first-world nations. Researcher Daniel Favre and his colleagues performed 83 experiment recording the reaction of honeybees to cell phones in their off state, standby state or active talking state. Worker piping in a bee colony is not frequent, and when it occurs in a colony, that is not in a swarming process, no more than two bees are simultaneously active. In Rome, the scientists manufactured the municipal water delivery canals and pipes out of lead, thereby causing the widespread lead poisoning of the population without even knowing it.

Whether it’s pesticides, cell towers, GMOs or some other technology, scientists always insist their technologies are harmless to the natural world, even while the sixth great extinction is now under way on planet Earth.
If we could turn off the cell towers, halt the GMOs, stop the spraying of pesticides and end the mass pharmaceutical contamination of our planet, then our honeybees (and other important animal species) might have a chance. And yet all the science in the world can’t create one scrap of real food that will keep you alive.
Now, I’ve involuntarily heard enough cell phone conversations tofully believe that too much time on the cell can rot the brain — atleast the brains of the folks who discuss their intimate lives inthe checkout lanes at WalMart. Still, the loquacious manifestation of cerebral insufficiency isa long, long stretch from glioma.
So when the New York Times starts running stories that implythat time on the phone with your brother-in-law could do more thanjust bore you to death, folks notice.
But this is a case where reading the whole story goes a long waytoward untying the knots in your stomach. So when the phone rings we can’t help but wonder if there isn’ta better reason not to answer than to avoid an unpleasant talk withanother bill collector.

So it can be used to prevent use of mobile phones in examination halls, confidential rooms, etc.
The moment the bug detects RF transmission signal from an activated mobile phone, it starts sounding a beep alarm and the LED blinks.
The lead length of the capacitor is fixed as 18 mm with a spacing of 8 mm between the leads to get the desired frequency.
It is a CMOS version using gate-protected p-channel MOSFET transistors in the input to provide very high input impedance, very low input current and very high speed of performance. This capacitor creates a field, stores energy and transfers the stored energy in the form of minute current to the inputs of IC1. As mentioned earlier, capacitor C3 should have a lead length of 18 mm with lead spacing of 8 mm. The unit will give the warning indication if someone uses mobile phone within a radius of 1.5 meters. He developed numerous, seemingly unrelated, symptoms, which eventually lead to Toxic Encephalopathy (brain damage due to toxic exposure), a brain tumor and cancer. He developed numerous, seemingly unrelated symptoms which eventually lead to brain damage, brain tumor, cancer. As you continue the exposure, then adverse health effects start to occur, you just can’t relate it back to what the cause or what the source was. There was a 2 fold increase in cancer risk for residents that lived 6kms away from the tower. There was little or no increased risk of leukemia if the children were exposed to less than 0.2 µT of EMFs. The study found that for subjects who had more than 1640 hours of cell phone use in their lifetime, whom they labeled as the “high risk group”, were 2 times more likely to develop a brain tumor in the temporal lobe. Infants who were exposed to radioactive radiation from the Chernobyl accident took on average 10 years before they were diagnosed with thyroid carcenoma. In blinded studies, the study is done in such a way that the patients or subjects do not know what treatment they are receiving to ensure that the results are not affected by a placebo effect.
The study found that most, if not all, independently funded research found an increase risk of gliomas.
The study found that as the number of hours with a cell phone increased from 0 to 4, sperm count and motility decreased in all user groups. This is a listing of 120 (the heading says there are 139 but I count 120) peer-reviewed scientific studies showing biological effects from RF radiation exposure of cell phones at levels below the recommended SAR levels. It is on a new subject to be discussed here in the capital so I hope you bear with me as we walk you through the thought process that led us to the introduction of this bill. I think we can say definitively that there are no industry studies that can prove that there are no health concerns for use extended over 10 years. Subsequent to those congressional hearings, the San Francisco department of Environment, which is represented here today, passed a resolution at the local level urging the mayor and the board of supervisors, which the mayor has now done and I want to recognize Mayor Garvin’s leadership on this issue, having introduced a local ordinance which does that which the bill we are going to discuss today will do. All of those are no doubt important factors, but new research carried out at the Swiss Federal Institute of Technology may have unveiled the real key: Cell phone signals. The induction of honeybee worker piping by the electromagnetic fields of mobile phones might have dramatic consequences in terms of colony losses due to unexpected swarming. If the honeybee population collapse continues for just a few more years, pollination of the global food supply may become nearly impossible.
Imagine the narrative of future historians: Humans multiplied and expanded their cell phone towers to the point where the pollinators all died. Science and technology has always come with a heavy dose of arrogance and willful ignorance. But human beings are too shortsighted to understand their role in causing almost anything that impacts the delicate web of life on Earth. Only Mother Nature can grow a plant from a seed, pollinate it, produce a flower and then a vegetable or fruit. The latest scaremaking the rounds — really, it’s just an old bugaboo revived andrefurbished — is the theory that talking on a cell phone will giveyou brain cancer.
The International Agencyfor Research on Cancer has classified cell phone use as a“possible” cancer cause.
We eat broccoli and drink green tea with anappetite fueled by hope and fear in equal parts.

It is also useful for detecting the use of mobile phone for spying and unauthorised video transmission. The disk capacitor along with the leads acts as a small gigahertz loop antenna to collect the RF signals from the mobile phone. The output CMOS transistor is capable of swinging the output voltage to within 10 mV of either supply voltage terminal. This will upset the balanced input of IC1 and convert the current into the corresponding output voltage. But 12V voltage make the circuit become too sensitive, it will trigger even if you switch on your room lamp, so I reduce the voltage to 9V and it work fine! I cant find the same capacitors with 8mm lead spacing and 16mm lead length as mentioned in the circuit. Desperate to determine whether a link existed between her husband exposure and his illness, our guest Carleigh Cooper began researching the effects of cell phone radiation on the human body and what she found is the basis of an eye opening book. I’m not holding it up to my head and the concern is about brain tumors, right?) Well there are a lot of deceptions and a lot of concerns. The study found that children who lived less than 2 km from the tower were 100 times more at risk of brain cancer. However, after 6-10 years of exposure, there was a 3 fold increase in the cancer risk for residents who lived less than 400 meters from the tower. The study found that men who lived less than 350 meters from the tower had no marked increase in cancer risk. The temporal lobe is the part of the brain closest to a cell phone antenna when it’s held next to the ear. It’s estimated that by the year 2030 close to 100% of the world population will have a cell phone subscription. In blinded studies, the meta-analysis found there was on average a 1.35 times increase in cancer risk for subjects who had more than 10 years of cell phone use. So when you hear the industry say that, “no this is safe we have looked at it and all of these federal agencies have.” None of them have worked with studies that go beyond 10 years and that is the concern because we know, especially with younger people who are starting to use them at 10 or 15 years of age, they are going to be using them for 3, 4, 5 decades and clearly even people my age approaching 60 have considerably been using them a couple of decades.
It will require that this SAR be disclosed to consumers at the point of purchase, both on their website and at the retail location; that this SAR will also be disclosed on the packaging, not on the cell phone itself, but on the packaging of the cell and also on all instructional materials.
The Scandinavian nations, Israel, Great Britain, Germany, France, and Canada have all taken steps to inform their consumers at the Federal level in all of these countries that parents should limit cell phone use for their children.
So humans will deny any responsibility for their actions, cover up the truth about what’s really going on, and even accelerate their own global population collapse. Cancer, I would venture,is closer to playing the slots: Hit on a certain combination offactors and claim the jackpot no one wants to collect. If we know the cause and can predict theeffect, we feel we understand, that we have some control, even whenthere’s little or nothing to be done.
We get scoped andprobed, irradiated and examined, hoping to tilt the scale just atad in our favor. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. Import charges previously quoted are subject to change if you increase you maximum bid amount.
Capacitor C5 (47pF) is connected across ‘strobe’ (pin 8) and ‘null’ inputs (pin 1) of IC1 for phase compensation and gain control to optimise the frequency response. The low-value timing components R6 and C9 produce very short time delay to avoid audio nuisance. The one that seems to be most prominent all the time is the work of brain tumor and brain cancer, and I think the reason why that has always been the focus is because that may never happen for 20 even 30 years. One of the deceptions of cell phones is that you can use your cell phone; you can be on it for 15 minutes, 30 minutes, an hour and there are no responses from your body for that use. The risk of lymphoma and leukemia increased 8 times for residents that lived less than 2kms away from the Surto tower. For residents who lived more than 400 meters away from the tower, there was no marked increase in cancer risk. However, women who lived less than 350 meters from the tower were 10 times more likely to have cancer.
The study also found brain tumors were twice as likely to be found on the same side of the head as phone use. They are in our lives to stay, they have enriched our lives, they have bettered our lives in ways that we are only beginning to understand.
This is the point I want to make, if there is reason enough for the FCC to have set an SAR standard 18 years ago and require in that SAR law that manufactures must notify the FCC what that SAR is, why shouldn’t we not require also that be disclosed to the consumer? Honeybees are absolutely crucial to the chain of life on planet Earth, and they are dying in record numbers. And in the end, when the history of our modern world is fully written, it will show how the scientists nearly wiped out the human race through their arrogance, their mass poisoning of the world, and their complete disregard for the value of life. Prior to ever developing damage, or brain cancer and most people don’t realize that there is a link. Over 4 billion people on the planet now are using cell phones regularly and that includes over 270 million Americans. So clearly if there is a standard, there was a concern that if it is above the 1.6 there is very serious or more serious health concerns.
Let consumers make informed choices and if there is no health concern whatsoever the question has to be asked why 18 years ago did the FCC set a standard? In France there is pending legislation which would outlaw marketing of cell phones to children. So although your brain has no pain receptors, and you are not feeling any kind of response, no headache, you assume that it is safe. This 1992 decision by the FCC was based on animal studies conducted in the late 1970?s and 1980?s. So, many of our trading partners have also already taken very significant steps forward, I think what we are proposing here today is very modest. So we are using tests that were done many decades ago, a standard that was set almost 2 decades ago.
So this standard was adopted decades before the concept of smart phones and devices so convenient that we carry them on our bodies continually and use them for hours on end and this standard has not been revisited since then.
