Now with an even longer light beam throw
883 ft from a set of two 10-watt lights!
CE approved for 2016+
Please check out the install and programing videos at the bottom of this page.
All LED Lights are not created equal!
Best value and long range performance in one package. Don’t fall victim to overpriced high lumen “rated” low performing lights. Put the light where you need it, not in the tree tops. No other LED light matches the long range performance of the Cyclops Long Range Optimus Series.
All Cyclops Long Range lights come with unbreakable polycarbonate lenses and utilize proprietary IRIS Reflector Technology. The Long Range series provides the ultimate focus for long range lighting by producing 883 ft. of usable light from a single 3.5″ tall, 10-watt LED. Compared to a standard 55 watt low beam headlight reach of 88 ft., and a standard 65 watt high beam reach of 153 ft.
Filters are also available for the Long Range Round Lights. These drastically change the beam pattern and offer a tunable lighting solution. You can run one wide angle filter and one spot, or two wide beam pattern filters. Mix or match for a very tunable system. Amber filters are great for fog or adverse conditions as well making a huge difference with conspicuous lighting.
The Long Range lights are available in three beam pattern options:
10° lights provide the most distance.
20° degree lights offer very good distance and a bit more fill than the 10 degree
The combo kit is one 10° and one 20° light. Use this setup on a Motorcycle with the 20° on the right side (USA) for an extremely good lighting setup.
60° lights are also available on special request
Cyclops provides very high quality wire harnesses. Several versions are available to suite your needs. A general UTV, ATV, Motorcycle or Automotive Harness is included with the base kit. We also offer a motorcycle harness with a handle bar switch.
For more control, check out the following options:
The Cyclops Raider CANbus Interface for BMW covers most wiring needs for the R1200gs, R1200GSA, and the R1200RT and allows for full integration and customization. Dimming, flashing, decelerometer functions, as well as additional outputs for heated gear or other accessories. Find more info here.
The Skene Dimmer option (for all bikes) offers the user several different operating levels from 0 to 100% in 10% increments. With the Skene unit you can use your existing headlight switch to operate the high and low beam with no other switches required, or choose the single pole handle bar switch option if you would like to turn the lights completely off while riding. 3 Dimmer harnesses to choose from:
- Dimmable Harness NO switch – Allows you to use your existing headlight switch to operate the high and low beam with no other switches required,
- Dimmable Harness WITH handlebar switch – allows you to use your existing headlight switch to operate the high and low beam AND/OR choose to turn the auxiliary lights completely off while riding.
- Dimmable Harness with alert feature – provides a short flashing sequence when the high beam button is pressed twice in quick succession.
- NOTE: 2013/16 BMW R1200GS, 2018 and newer KTM1290R and S with the factory LED headlight require the Cyclops Raider CANbus interface in order to get dimming features. The Skene is not used on these bikes. KTM CANbus version to be available in early March.
– 883′ of Usable Light from 10-watt LED
– Proprietary IRIS Reflector Technology
– PWM Integrated Dimming Circuitry
– Integrated Electronic Thermal Management (ETM)
– Available as 2 Light Set with Wiring Harness
A single Long Range Optimus throws 1 lux of light 883 feet.
For comparison, a motorcycle headlight low beam measures 1 lux at 88 feet, and high beam 1 lux at 153 feet.
Prime Drive runs the LED more efficiently while managing heat levels. This means more light from the LED and a longer lifespan. This is advanced LED technology in action. Electronic Thermal Management (ETM) monitors the heat output of the LEDs and makes use of integrated Pulse Width Modulation (PWM) circuitry to maintain safe operating temperatures and prolong the LED life span to its full 50,000 hour potential. PWM dimming circuitry works at managing heat levels by flashing the LED at a frequency faster than the human eye can detect, thus reducing the time that the LED is operating while still delivering 100% light output.
Compact and small design doesn’t mean weak either, as the Long Range Optimus doesn’t sacrifice light output to achieve an ultra-compact housing, in fact it’s the opposite. These lights outperform traditional halogen off-road lights in both distance and output while fitting within a housing that doesn’t look bulky and in the way.
Put away the huge, awkward looking lights, and get the driving lights that will amaze you every time you light them up!
Choose the light beam pattern you want, and if you want a dimming or non dimming harness. The price of the option will be added to the base price of $299.95

Howdy, y’all! I bet you thought you’d seen the last of me! To be perfectly honest, I thought so, too—I’ve been trying to draw illustrations of octahedral and tetrahedral interstitial sites for the past fifteen minutes, with basically no success. Because of that, I’ve returned to the part of inorganic that I’ve alluded to but glossed over for the past week or so: semiconductors!
Boring, you say? I thought so too, but then I really thought about it, and, well, I like my computer (and my phone and my calculator and…)
In my post on metals, I talked about why metals conduct electricity. It has to do with that lovely little thing called band theory, which my professor referred to as “solid state physics.” Altogether now! Uuuuuughh…
Now, if we undergraduate (or high school or…) students had our way, we would call it quits there and say, “Okay! Metals are hard! Everything else is nonmetal!” However, because the world is big and beautiful, it doesn’t quite work that way. You know from looking at the periodic table that there are a handful of these lovely, cringe-worthy things called “metalloids,” and, as you expect, they can’t make up their minds. Although indecisiveness is generally called something like “irresponsibility” or “you just want go wherever you’ll get food” in my house, when it comes to elements, these actually serve a pretty good purpose.
Take that, leadership workshops!
Yup, the metalloids are a very important class of materials called “intrinsic semiconductors.” Now, what does that mean? I’m so very glad you asked, because I have to tell you regardless. (I have a test tomorrow, you know.)
Well, semiconductors are solids with an energy gap between their filled band and their empty band. This is pretty much what you’d expect from something straddling the “metal” fence: metals have a single partially-filled band, nonmetals have separate orbitals, and metalloids have separate bands.
Now, the key here is that, while semiconductors do have separate bands, they aren’t that far apart in energy. Ideally (at 0 Kelvin), all of their electrons are in their lower-energy band (the valence band) and their higher-energy band (the conduction band) is completely empty. However, as you start adding energy to the semiconductors with heat, electrons gain enough energy that they can hop the gap.
This sounds really useful at first pass, but if you think about it, it’s tragically inconvenient; yes, semiconductors are very useful for use in electronics and such, but imagine if the conductivity of the semiconductors in your computer varied wildly with temperature. It’d make things a little hard to manage, really. For this reason, the only truly useful purpose that intrinsic semiconductors serve is to measure temperature—they’re put in temperature-monitoring devices called thermistors, in fact.
Add some impurities in, though, and it’s a whole different ball game. This is called “doping,” and it alters the electronics of the semiconductors just enough to make them actually useful and reliable at the temperatures they’ll be used in. This produces “defect” semiconductors of two types: p-type and n-type.
P-type semiconductors result from doping an intrinsic semiconductor with a relatively electron-deficient atom. For example, add boron to silicon, and you’ve got yourself a p-type defect semiconductor. These work by introducing atoms with empty energy levels that lie just above the valence (full) band in the semiconductor. Electrons can easily hop from the valence band to these isolated energy levels, generating positive (thus the p) holes in the valence band that will conduct charge.
N-type semiconductors, in contrast, are produced when a pure semiconductor is doped with an electron-rich atom, like putting phosphorus in silicon. This introduces filled energy levels just below the conduction band of the semiconductor; electrons easily hop from the dopant to the conduction band of the semiconductor, generating negative (n) charges that conduct charge.
It’s very important to note that p-type semiconductors are higher in energy than their respective n-type semiconductors. This is because the electron-deficient dopants experience a smaller effective nuclear charge than the semiconductor, whereas the electron-rich dopants experience a higher effective nuclear charge than the semiconductor.
(I can’t explain this better, unfortunately. The subject has been overrun by physicists online. If you find a good resource, let me know! Please! Pls. Pls.)
Okay, so that’s great, but what about it? Well, turns out, defect semiconductors have some awesome applications. If I have time, I might get into it. First, though, I have to go back and review crystal closest packing, which is sure to be oodles of joy.
Questions? Comments? A good (chemical??) explanation of band-bending across a p/n junction? Put ‘er down there, please!

Not so long ago, Bluetooth headsets used to be a complete flex. We only saw a separate group of people who used to rock this device about 10 years back. But, as time passed, a lot of better alternatives to Bluetooth headsets started showing up in the market. And these alternatives caused people to ditch Bluetooth headsets. One alternative to Bluetooth headphones is wireless earbuds. But, a lot of people who use a hands-free wireless headset solely for calling, and not for listening to music still seem to prefer Bluetooth headsets over their fancy and improved versions. This is mainly because they are usually pretty lightweight, affordable and less complicated.
Today, if you go out in the market looking for Bluetooth headsets, you will be left l overwhelmed by how many there are available. And among all the clutter, only several Bluetooth headsets pass the minimum usability test, so it becomes pretty hard for an average user to get a usable piece. Keeping this in mind, we have created a list of the 5 best Bluetooth headsets that you can find right now. Along with the names of the Bluetooth headsets, we have also reviewed them and listed their pros and cons so you can pick the one that suits you best.
With that said, here is everything you should look for in a Bluetooth headset when you are in the market for buying one.
- Call quality: Primarily, you would be buying a Bluetooth headset for calls. So, the first thing you should be looking for in a Bluetooth headset is its call quality.
- Battery: Battery should be a major concern for you if you plan on using your Bluetooth headsets for lengthy calls, or other high output work. What happens is that sometimes people do not focus on the battery size until they start using their Bluetooth headsets and realize that they are running out of battery fast. Small-sized batteries can come in the way of your important calls, so make sure that you keep the battery size into consideration when buying a Bluetooth headset.
- Noise-cancelling Bluetooth headsets: Noise cancellation is one of those features that one would not truly appreciate unless they have tried it. So, even if you feel like you do not need noise-cancelling Bluetooth headsets, we would suggest that you get them. The main reason for this is that noise cancellation just takes your calling experience to a whole new level. And, you simply can't have that in a Bluetooth headset that does not have noise cancellation.
- Comfort and cushioning: Some Bluetooth headsets have great call quality, battery, and noise cancellation. But, you just can't wear those headsets for long periods without your ear itching, and your head hurting. This is because those Bluetooth headsets have terrible comfort levels. So, if you wish to wear your Bluetooth headsets for long hours, make sure that the Bluetooth headset that you are getting is comfortable. Obviously, you can't wear Bluetooth headsets before buying when you are shopping online. So, I guess you will have to take our word for it. We have mentioned the pros and cons of each Bluetooth headset if it is comfortable and suitable for wearing for long hours. So, you get an idea about the comfortability of that specific headset.
- Range: Keeping the range of Bluetooth headsets in mind is very important if you plan on taking your headsets away from the connected device a lot. But, the problem with headsets having large ranges is that they are expensive and also bigger as compared to headsets with normal ranges. Most Bluetooth headsets work perfectly fine in 25-30 feet. This range should be enough for most people.

Buying Guide for the Best Bluetooth Headsets
Now that you have read reviews of the 5 best Bluetooth headsets. You are ready to make a decision. And, we are going to help you in making your decision with a buying guide. The buying guide below will educate you about the things that you should be looking for when buying a Bluetooth headset.
Audio quality on-call is definitely the first thing you should be concerned about when buying a Bluetooth headset. You would be primarily getting a Bluetooth headset for making and receiving calls, and if it sucks at doing that, then there is no point in getting one in the first place. So, always check the call quality of a Bluetooth headset before you go on and buy it.
If the speaker or the mic of your Bluetooth headset is not perfectly functional. Your whole experience will turn into a nightmare. You would not be able to hear your calls properly if the speaker is muddy or weak. And, in the same way, if there is any problem with the microphone, you would sound terrible to the person you are on call with. To avoid all of this, always keep call quality on the top of your mind when you are getting a Bluetooth headset.
Noise cancellation in Bluetooth headsets is essential. It lets you make and receive calls in crowded places. And, if you are someone who receives calls on the go. Then, you would be needing noise-cancelling headsets. So, check the noise-cancelling results of a Bluetooth headset before you make a purchase. Also, some headsets have noise-cancelling microphones. What these microphones do is that they cancel all the background noises in your surroundings. And only transmit your voice to the person you are on call with.
Also, you should know that there are two types of noise cancellations. Active noise cancellation and passive noise. Active noise cancellation is mightier and cancels more noise. But some people are fine with Bluetooth headsets with just passive noise cancellation. It is totally up to you depending upon how much noise cancellation you are okay with.
If you are a power user who is going to stay on calls all the time. And will not be having much time to charge your Bluetooth headset. Then, battery timing should be on the top of your priority list. Most importantly, get a Bluetooth headset that gives a long battery backup. One of the Bluetooth headsets we reviewed above gives a battery backup of almost 2 days. Getting a Bluetooth headset with such long hours of battery backup will never let you down.
Comfort should matter for you as headsets that have uncomfortable headbands and headpieces are a total nightmare to wear for long hours. And if you are planning to wear your headsets for hours, comfort is something you should not compromise on. When you are getting a Bluetooth headset from our list. See if we have added comfort to its pros, and mentioned explicitly that the headsets are perfect for wearing for long hours. And, then buy it because we really do not want you to get a headset that is a nightmare to wear.
Obviously, at the end of the day, you will have to take our word for it. Comfort is something that can vary from person to person. We might find something comfortable to wear, but there is a chance that you might find that same thing uncomfortable.
What we can suggest is that if you want to buy Bluetooth headsets purely for calls, and you plan on wearing them outdoors. Then, single-ear Bluetooth headsets can be best for you. They are super lightweight and do not add any weight to your ear. You can wear them for long hours without even knowing that you are wearing them. If you want to wear Bluetooth headsets indoors, then a pair with good cushioning can prove to be comfortable.
Most Bluetooth headsets offer a decent range of 25-30 feet, which should be enough for most people. However, if you wish to stay too far away from the device you are connected with. Buying a Bluetooth headset with a large range can make it possible.
Also, as I said, Bluetooth headsets with larger antennas are bigger in size and a little heavier so you will also have to compromise on comfort for the sake of getting extra range. In my opinion, there is no need to get greedy for a large range as you would not probably even need it. However, make sure that the headset you are buying has a minimum of 30 feet range.
So, think twice before you decide to get a Bluetooth headset with more than normal range because that extra you would pay for a better range would be no good if you do not actually need it.

How to install a Parking Sensor on the car by yourself.
Parking sensor – most drivers can no longer imagine parking without this smart device. The days are long gone when there were no other options to park your car except manual mode.
It is possible to install a Parktronic on your own, having basic concepts about the work and installation of electrical equipment of the car.
The display will be installed on the rearview mirror.
Preparing and marking for installing parking assist sensor.
Take a box with a parking sensor kit. And check its equipment. It contains a block of wires, a set of parking sensors, a central control unit, a frieze for drilling a hole in the bumper, ties, and tape for marking.
You need to clean and dismantle your bumper, remove all unnecessary things from it. Look under the bumper and determine the distance at which we have its amplifier.
Determine whether we have a reversing light (left or right) and depending on that we pull all the wires there. A wire from the mirror, and from the Parktronic display, pull into the trunk. The main block of the parking radar shall be installed in the same place. All of this will be connected to the reversing lamp on the left or right (determine where it is located).
With the laser level marking the middle of the bumper, it greatly simplifies the process.
In order to set the Parktronic, we make the marking to the right and left of the bumper center, with a certain interval. For two central Parktronics, it is wider than for the other two.
After we have made all the markings, we make holes in the bumper with the laser cutter. The distance between all sensors is symmetrical, approximately 40 cm each.
Go to the next stage.
The next step is laying the wires of the Parktronic.
Put the numbered wires to the letters A.B C.D.
Laying the wires through the drilled holes, each in turn. After we put all four wires separately through the drilled holes, coil all of them together into one wire. Get them into the trunk through a special hole.
Select a place for the central unit and fix it.
Because the wires are long, we twist them and hide them in the side hole of the car.
Now let’s go to fixing the monitor and laying wires from the monitor to the central unit.
For this purpose, we use a rearview mirror, on top of it, and attach our monitor.
As the mirror has a spherical shape, for fixing the monitor we use double-sided adhesive tape.
We fix the wire on the mirror’s leg and lead it under the car ceiling trim to the rack and further along the side surface to the rear of our car.
Connect the wire from the display, four wires from the parking sensors, and power wires to the central unit.
Check that the connection is correct. We are looking for positive and negative.
Let’s go to the last part.
Installation of parking car sensor
- Reduce the length of wires on which we attach parking sensors. A little squeeze the tendrils.
- Check all the parking system.

The WiFi Blues
by Jeffry Fawcett, PhD
Wireless broadband Internet access is all the rage. The noise is drowning out concerns for this technology's risks.
Philadelphia, the city of brotherly love is going to have it; many in San Francisco want it:
Wireless broadband Internet access (WiFi). It seems too good to be true. At relatively low cost, anyone can get on the Internet anywhere in a city. All the city needs to do is install a network of WiFi antennas.
An often-repeated argument in favor of citywide WiFi is that it will help close the digital divide: the poorer you are, the more limited your access to the Internet and its wealth of information resources. Cities like Philadelphia and San Francisco are actively trying to close the digital divide. One option is WiFi.
Yet in weighing the options, virtually nothing is heard about the potential health risks. Saturating an entire city with WiFi adds to the existing burden of radio frequency radiation (RFR). That burden, called electrosmog  by some, consists of long-term exposure to low-levels of nonionizing electromagnetic radiation in the radio frequency and microwave range from familiar sources like radio and TV broadcast signals, radar, and the ubiquitous cell phone.
Henry Lai, PhD has been researching the biological and health effects of RFR for 35 years. His research focuses on the effects of RFR in the range used by cell phones and other wireless technologies. His laboratory at the University of Washington in Seattle is the single remaining lab in the US that conducts such research. Ten years ago it was one of four.
There is no funding in the United States for research of the biological and health effects of RFR and EMF. No foundation, government agency, or corporation will lay down money to help clarify the science behind concerns about WiFi, cell phones, and other wireless devices. Dr. Lai keeps his lab going by doing cancer research, some of it concerning the use of electromagnetic radiation to treat cancer.
In Europe there are many well-funded projects in RFR research. Citizens are more organized. Public figures have championed the issue. And the European Union has a much greater public health orientation than the United States. These days we have to rely on the Europeans for the science of wireless technology health risks.
It was not always so. For example, in the early 1990s the Cellular Telecommunications and Internet Association (CTIA) came up with $25 million for research into the potential health effects of cell phones. The CTIA is the cell phone industry's trade organization. Their intention was to lay concerns about cell phones to rest. The Wireless Technology Research (WTR) program administered the funds and research program. When the $25 million was spent, the WTR final report submitted in 2000 recommended further study. The CTIA cut a deal with the FDA to spend another $1 million to review further research.
The money is still there. The FDA has been waiting since 1999 when the deal with CTIA was cut to spend the money.
FDA plans to convene a meeting in the near future to evaluate all completed, ongoing and planned research looking at health effects associated with the use of wireless communication devices and identify knowledge gaps that may warrant additional research.
Initially, the WTR found no cause for concern. But in 1995 Dr. Lai and his colleague NP Singh, PhD found that exposing the brain cells of rats to RFR at a level similar to cell phones produced breaks in strands of DNA. Their discovery was a turning point in the research and in the CTIA's enthusiasm for the project. Dr. Lai and Dr. Singh had uncovered a mechanism that explained how RFR exposure might cause health effects.
Since 1990 Dr. Lai has maintained a database of research on the effects of RFR on humans, lab animals, and cell cultures. He has amassed over 300 studies published in peer reviewed scientific journals. To avoid bias, he excludes his own research from the database.
Of these studies, 56% show a biological or health effect from exposure to RFR. These effects include:
- genetic effects such as damage to DNA,
- cellular and molecular effects such as a reduction in enzymes critical to the central nervous system,
- changes in electrophysiology such as reduced activity between nerve cells, and
- physiological and behavioral changes such as impairment of peripheral vision.
An interesting thing happens when the studies from Dr. Lai's database are placed in two stacks: one of studies funded by the wireless industry (30% of the studies), the other stack of independently funded studies (70%). Of the studies that show a biological or health effect from wireless RFR, 14% are industry funded while 86% are independently funded. Of studies showing no effect, 49% are industry funded while 51% are independently funded.
To make the point another way, of industry funded studies, only 27% found an RFR effect. Independently funded studies found an RFR effect 68% of the time. This discrepancy is consistent among the effects listed. Of studies that found an effect on cancer, 11% were industry funded, 47% were independently funded. Cellular and molecular effects: 19% industry, 69% independent. Electrophysiology effects: 33% industry, 77% independent. Physiological and behavioral effects: 57% industry, 83% independent.
If Dr. Lai's research were included in the tally, the percent of studies showing an effect from RFR would be even greater. But when Dr. Lai is asked about these statistics, he often says that 50% of the studies show an effect. And then he points out that 50% is a significant number, significant enough to justify a precautionary approach that minimizes exposures.
The differences between the industry funded stack of studies and the independently funded stack suggest bias. Bias enters research through the way a study is designed, the methods used in the study, how data is collected, and how results are interpreted. It might be that some independently funded researchers are biased because they are consumed by a burning passion to eliminate RFR exposures or, even more sinister, destroy the wireless industry. They might have consciously or unconsciously designed their studies, chosen methods, collected data, and interpreted the results to show health effects from RFR. However, the rewards for doing so are not great. Many researchers who advise precaution regarding RFR have been ostracized or their research funding has been slashed. Careers have been stalled and in some cases terminated – hardly circumstances that would encourage jumping on that particular bandwagon.
The rewards for producing industry-friendly results are obvious: funding, professional recognition, a clear career path, and employment opportunities in industry. This is not to say that these researchers are dishonest. It is to say that rewards are more likely as a consequence of producing the "right" answers. In other words, researchers typically aren't corrupted into conducting biased research. More often they're already biased and the rewards flow to them as a consequence.
Within each group, whether industry or independently funded, results don't always agree –some studies show an effect while others do not regardless of who did the funding. That difference suggests another kind of problem: scientists don't know enough yet to conduct decisive experiments that can produce something like a professional consensus regarding the biological and health effects of wireless RFR. Many of the scientists who work in this field and who believe that there's ample reason for concern will say that the science is not yet conclusive. This drives some activists crazy. Yet it is a true statement about the state of the science.
We should not be surprised that this lack of conclusive science has led the wireless industry to claim that cell phones and other wireless technologies are safe. The FDA is with them, stating that
[t]he available scientific evidence does not show that any health problems are associated with using wireless phones. There is no proof, however, that wireless phones are absolutely safe.
This carefully constructed statement is intended to reassure us. Yet Dr. Lai's database puts the lie to the first sentence: it's simply false. The framework set up for us is that a technology should be adopted unless there's conclusive evidence that it does harm. Not all regulatory agencies think this way.
The UK's equivalent to the FDA, the Health Protection Agency (HPA), has declared a voluntary moratorium of marketing cell phones to children as a precautionary measure. The moratorium has so far been observed by the UK cell phone industry. The HPA opens its discussion of the health risks from cell phones by saying that
There is a large body of scientific evidence relating to exposure to radio waves and there are thousands of published scientific papers covering studies of exposed tissue samples (e.g. cells), animals and people. It is not difficult to find contradictory results in the literature, and an important role of the HPA Radiological Protection Division (RPD) is to develop judgments [sic] on the totality of the evidence in controversial areas of the science.
Unlike the FDA, the HPA points to contradictory science regarding cell phone radiation. The reassurance is that they're paying attention, not that cell phones very likely don't cause harm. The HPA goes on to cite the National Radiological Protection Board (NRPB), which reviews the science and recommends standards. The NRPB and with it the HPA explicitly adopt a precautionary standard. With regard to children, the NRPB's 2004 report recommends that
in the absence of new scientific evidence, the recommendation in the Stewart Report on limiting the use of mobile phones by children remains appropriate as a precautionary measure.
In 2004 the International Association of Fire Fighters (IAFF) decided that they will not permit cell phone antennas on fire houses. The decision was made by resolution at the IAFF's annual delegate assembly. The resolution directed the International to review the potential health risks from cell antennas. If the science demonstrated a risk, then the union would oppose the use of fire stations as sites for cell antennas until further science demonstrated that cell antennas are safe.
The resolution was passed in August 2004. In April 2005 the union's Health and Safety Department completed the review of the science. They found more than ample evidence to conclude that the union should oppose cell antennas on fire stations. The position paper included 49 references and a bibliography of 40 citations. Based on that evidence, the resolution cites a wide range of effects experienced by fire fighters:
Three things are worth noting about the substance of the resolution and the union's official position. First, the fire fighters were focused on their ability to do their job. Second, fire fighters were involuntarily exposed to a health risk. And third, the fire fighters oppose cell antennas on fire stations until they are proven safe.
- slowed reaction times,
- lack of focus,
- lack of impulse control,
- severe headaches,
- anesthesia-like sleep,
- sleep deprivation,
- tremors, and
The decision that the fire fighters faced – a decision we all face – is how to evaluate the safety of wireless technologies and decide what level of involuntary risk we are willing to take.
So consider this: 47% of independently funded studies found cancer effects, 69% found effects on cell function, 77% found effects on electrical signaling in the body, and 83% found physiological and behavioral effects. Suppose you have several hundred marine biologists study your swimming pool. 47% (or 69% or 77% or 83%) of the biologists say you've got a shark in your pool. Would you dive in? Would you let your kids dive in?
- Use it unless there's good evidence that it's harmful.
- Or don't use it until there's good evidence that it's safe.
Citywide WiFi is only the latest RFR wireless technology to place us involuntarily at risk. Cell phone networks are the best known, which include personal digital assistants (PDAs) such as the Blackberry™. Wireless networks at home and at the office are newer than cell phones and are another RFR exposure. Even if you don't have one, your neighbor might and that will expose you. Also relatively new are the Bluetooth technologies used for applications such as hands-free telephone headsets which operate using RFR. The familiar cordless phone is another RFR exposure that might put you at as much risk as a cell phone.
What these technologies share is reciprocal receiving and transmitting of RFR signals between an end-user device and antennas that link the device to a network. There are three characteristics of these RFR signals that are believed to contribute to the biological and health effects of wireless technologies: signal strength, frequency, and modulation.
Citywide WiFi uses a signal strength similar to cell phones. Signal strength is measured in watts, a standard unit of energy. Wireless networks for the home and office have less signal strength (although they can be increased with boosters) while Bluetooth devices and cordless phones have even less strength.
All of these technologies use roughly the same frequency band: 0.3 to 3 GHz. GHz stands for gigahertz. A hertz is a standard measure of electromagnetic radiation created by sending an alternating electrical current through an antenna that is one cycle per second. A gigahertz is one billion cycles per second. The higher the GHz, the faster the current alternates.
An alternative way of measuring RFR is in wavelength. Wavelengths have an exact and inverse relationship to frequency: higher frequencies correspond to shorter wavelengths. Visible light is electromagnetic radiation with higher frequencies and shorter wavelengths than RFR, with red light having a lower frequency and longer wavelength than blue light.
Modulation refers to whether the signal comes at a constant frequency (as in AM radio and analog cell phone systems) or in pulses (as in FM radio and digital cell phones). All digital wireless technologies are pulsed.
Risk increases with signal strength. The frequencies used by wireless technologies are to some extent "ideal" for affecting our bodies because the wavelengths are at a human scale. Digital (pulsed) signals are of greater risk than analog signals.
Short-term, high-intensity exposures to wireless RFR have received the most research attention, in particular the acute affects of cell phones. Far fewer studies have looked at long-term effects of cell phone use let alone the use of other wireless devices. Even less studied are the effects of the low-intensity, persistent exposure to RFR from cell phone and WiFi antennas.
Much of the discussion about RFR health effects is framed as a concern with people who are electrohypersensitive. Unlike immune-mediated hypersensitivity that responds to allergens, electrohypersensitivity is a reaction to nonionizing electromagnetic radiation from video display monitors, cell phones, cordless phones, wireless routers, or other RFR source. Characteristic symptoms of electrohypersensitivity can include:
Critics argue that electrohypersensitivity is not a physical ailment but a psychological one. Research led by Olle Johansson, MD at the Karolinska Institute in Stockholm identified changes in mast cells in electrohypersensitives. So Dr. Johansson exposed rats to RFR exposures similar to his human subjects, assuming that the rat psyche is not predisposed to produce the symptoms of electrohypersensitivity. The study produced results similar to what he found in human subjects: enlarged mast cells aggregated close to the surface of the skin. Dr. Johansson went further and tested both electrohypersensitives and nonsensitives human subjects in similar exposures. Though the nonsensitives had no hypersensitivity symptoms, the mast cells in their skin showed the same behavior as electrohypersensitives, although the effect was less severe. Based on this research, Dr. Johansson and his colleague Shabnam Gangi proposed one mechanism for the health effects of RFR as an immunological response, hypothesizing as to how this mechanism affects internal organs such as the cardiovascular and neurological systems.
- localized heat and tingling,
- dry upper respiratory tract and eye irritation,
- brain fog, headache, and nausea,
- swollen mucus membranes,
- muscle and joint pain,
- heart palpitations, and
- progressively severe sensitivity to light.
In The Invisible Disease, Finnish journalist Gunni Nordström associates electrohypersensitivity with multiple chemical sensitivity and chronic fatigue syndrome. People in Sweden made electrohypersensitivity a public health issue when cathode ray tube-based video display monitors were introduced into offices. The rise of Silicon Valley – both in the original Silicon Valley and the many Silicon Valleys that have developed around the world – gave rise similar health effects among computer manufacturing workers. Researchers observed a relationship between materials used in products and their synergistic reaction with electromagnetic radiation. But both funding for research and data collection on occupational health quickly dried up when these issues came to light.
Electrohypersensitives are not an unlucky few. They are likely harbingers in a complex landscape of environmental risks. Just like any other environmental stressor, RFR affects some people more than others. And as with other environmental stressors, the greater the overall burden, the greater the risk of becoming one of the "unlucky few."
Citywide WiFi adds to the existing burden of RFR. Just as burning more fossil fuels adds to the level of smog, adding more RFR adds to the level of electrosmog. You don't have to expose your home or your city to the increased burden created by WiFi. There's a viable alternative: a wired Internet access and network. The hype might make it seem less convenient and more expensive. But what's a good night's sleep worth? Or reducing your risk of cancer?


The e-Racer takes its first steps.
For many, the racetrack is synonymous with the thunder of engines. But the future of racing isn’t about who’s got the biggest roar – it’s about who’s got the best performance and innovation. What if the most powerful engine was also the most silent? CUPRA knows that true power comes from within, and we’re ready to open the bonnet and let the world take a look in.
The CUPRA e-Racer, the first vehicle in total compliance with E-TCR Technical Regulations, has successfully completed its first run on the track in Croatia. With the help of a passionate team of automotive battery experts at Rimac Technology, we tested the e-Racer at various speeds to ensure all four engines provide integrated and calibrated rear-wheel traction. While some e-cars suffer from issues stemming from advanced systems and controls, the CUPRA e-Racer finished its first run with zero incidents. This was the first time a completely electric CUPRA competition car had touched the track – and our first step down the path of redefined racing.
“Our initial uncertainty due to the complex integration of the new electrical systems quickly gave way to optimism as the CUPRA family’s first electric car – the first ever fully electric touring race car – completed its inaugural run on the track,” said Xavier Serra, Head of Technical Development at CUPRA Racing. “This represents one more step towards our goal of reinventing racing and the racetrack experience.”
The CUPRA e-Racer’s successful first run not only demonstrated the impressive potential of this “electric machine”, but also showed the world that e-racing isn’t just a possibility – it’s the future of racing. And the e-Racer is here to lead the way.
These solid first steps are just the first of many to come. All electronic systems run smoothly. All four engines are properly calibrated. But we know we are capable of so much more. That’s why the CUPRA e-Racer’s next stop is the Castelloli Circuit, where we will continue to fine-tune its intricate electrical systems and push it to its full potential. And we firmly believe the CUPRA e-Racer will be more than ready to take on the track at the Circuit de Barcelona-Catalunya in the final event of the 2018 TCR Europe Series this October.
For true lovers of the track, passion for racing isn’t something you can see or hear. It’s something in your DNA.

This meant some serious noise control designs to ensure that the room was as quiet as possible. Through the trickery of electronics acoustic environments can be anything from a dry sounding living room to a large gothic cathedral.


DNS stands for Domain Name System (or specifically Domain Name Server). It helps computers and devices find websites on the internet. Imagine the internet is like a big city, and each website is a house, that is located within a neighbourhood in that city. To visit a house, you need to know its address. In the same way, to visit a website, your computer needs its address too. DNS works like a phonebook, helping your computer find the address of the server (the neighbourhood) that hosts the website (house) you want to visit.
How DNS Works
- You specify a website name: When you want to visit a website, you type its name (like www.example.com) into your web browser.
- Asking the DNS for help: Your computer doesn't understand the website's name specifically, so it asks the DNS for directions to website's actual server location.
- DNS finds the address: The DNS looks in its phonebook and finds the specific server (A computer that has been assigned a specific Internet Protocol or IP address) that matches the website's name.
- Your computer visits the web server: Once your computer has the IP address, it can visit the server that the website lives on. From there traffic is routed to your specific website's file structure.
Imagine you want to visit www.example.com.
- You type www.example.com into your web browser.
- Your computer asks the DNS, "What's the address for www.example.com?"
- The DNS finds the IP address (like 184.108.40.206) for www.example.com.
- Your computer uses the IP address to visit the website.
So, DNS helps your computer find websites on the internet by turning website names into addresses that your computer can understand.
There are thousands of DNS servers around the world. Your computer or internet provider utilizes a local or specified DNS server to provide the specific location of internet services. All the world's DNS servers are synchronized to provide the same data so that a website request anywhere in the world will point to the user's web browser to the same place. When a change is made to a website or web server, it usually takes between 12 to 24 hours for this change to propagate around the world. In that time, traffic can be routed to the old OR the new server, depending on how well the change has been propagated.


Nord CE 2 Lite has entered India with OnePlus 10 R 5G. However, the company did not provide any information about the launch date of the phone. It is expected to launch soon.
Smartphone company OnePlus is going to launch another new phone in the popular Nord series soon. The company recently mentioned the OnePlus Nord 3 on its official website. Interestingly, Nord 3 has been mentioned before on Indian websites. From which it can be inferred that it may be launched in India first.
Mobile tipstar Mukul Sharma shared this information on Twitter. A few days ago, the OnePlus Nord CE 2 Lite entered India with the OnePlus 10 R 5G. However, the company did not provide any information about the launch date of the phone. It is expected to launch soon.
50MP rear camera
According to reports, the Nord 3 will play MediaTek Dimension 8100 chipset and will come with other high mid-range specifications including 6.7-inch display and 120Hz refresh rate. It is also expected that the phone will share some features with the recently launched OnePlus 10 R. It has a 50 MP main camera, 8MP ultraviolet and 2 MP depth sensor on the back. Also, the phone is expected to have a 16 MP front camera.
4500 mAh battery
Talking about the other features found in the phone, it can get a 4500 mAh battery and 150 W fast charging. As we have seen in OnePlus 10R. The phone could be launched with a lower-end chipset than the Dimension 8100, as the Nord series is expected to be a watery-down version of the brand's number-series. Other setups like camera setup can be similar to 10R.

Ethics in Space
In the last four decades space technology has achieved a high capability which has led to the building of orbital stations and satellites for communications, earth observation and the positioning of earth-based mobile communicators. Germany has played an active role in space research from the earliest stages. By participating in the new international space station, Germany will open up new possibilities for space based experiments.
The main goal of the use of space technology is to obtain information, energy or material to enhance the quality of life on earth. This global dimension of scientific and technological development contains benefits but also presents new risks, which involve the need to protect humans through the help of social, legal, and ethical research based on moral reasoning in identifying ethical dilemmas. Within the framework of the World Commission on the Ethics of Scientific Knowledge and Technology (COMEST), a working group on the Ethics of Outer Space was set up. The study group supported the scientific work of this working group by considering, in particular, ethical questions, the spatial limits of human action, the exploration of space, the scientific research of space, and the commercial utilisation of outer space.
The study group finished its own work and its presentations by reporting about the UNESCO-project, “The Ethics of Outer Space”.
