How Difficult Is It to Build a Basic Transmitter and Receiver

If you're interested in RF experimentation and you prefer to work in a virtual environment, try GNURadio. It runs in linux, and has the basic virtual components to build a variety of RF systems, including basic FM/AM transceivers. There are many online tutorials to get you started with the basics, and you don't need a lab or any parts. You just need a laptop and some time. When you want to implement your designs in reality, look at getting a cheap SDR (Software defined radio). They typically plug into the USB port of your computer, and can be purposed for almost anything (within the limitations of the SDR itself, of course!)

Preferably something that could transmit LED lights, like patterns. After that I'd like to advance to audio and video. But for the basic radio transmitting and receiving how difficult of a job would that be? and what tools and parts would I need? I've worked on a off with electronics for about a year so I know about capacitors, resistors, transistors,transformers, arduinos, basic C and Python Programming. I think I could do this job but could use some guidance and information.

Save Electricity Bill by Switching to LED Lights
Without any doubt, lights are the important things for a human to survive in the world. Are you worried about the electricity bill? If yes, then there is the smart solution which reduces the usage of electricity thereby consuming less power. In the past decade, the popularity and the usage of LED lights become high. This is not only used for lighting but also used to decorate the homes, office space and gardens. LED light housing is the best option to decorate the pace beautifully. In this post, you may find the reasons why you should go with LED lights.Energy efficientWhen we consider the normal bulbs it consumes only 50 to 60% electricity for lighting and the remaining is converted into energy. Where in case of Light Emitting Diode it uses more than 80% electricity for lighting remaining as energy. It is common that the brightness of the light will become dull after few months. But it is not true in term of LED lights.Conventional forms of lights produce heat and release Ultra Violet radiations. LED bulbs are environment-friendly and the UV radiation produced by the light is almost equal to zero. LED high bay Housing helpful to decorate your house. There are no filaments used in LED lights and it can last up to ten times longer than standard lights.The color options available in LED lights are more compared to traditional lights. The government also highly recommends LED lights for the efficient use of power. You may find most of the Street lights are LED.Most of the people have the common question that is the LED lights fix for all types of fixtures? The LED lights are designed to fit into various types of fixtures. So you don't want to worry about the fixtures. Nowadays lights are available in various shapes and designs this enables the customer to decorate their home and brighten their homes.Applications areasLED lights not only recommended for residential areas this also recommended to use in the commercial places and public places. This lights also used in car lights. You can protect the light from various climate factors like rain, winter with the help of LED Streetlight housing service offered by the best LED housing manufacturers in India.

Are LED Lights Eco-Friendly?
Light-emitting diodes are an eco-friendly lighting choice. LEDs are an energy-efficient alternative to traditional incandescent light bulbs, which waste 90 percent of the energy they consume on heat. Other energy-efficient lighting options include halogen incandescent bulbs and compact fluorescent lamps. All incandescent and fluorescent lights produce light that flows in all directions, wasting light as well as heat.LEDs are a rapidly advancing technology that uses energy more efficiently and can save energy in indirect ways, such as with air-conditioning costs (see References 1). LEDs use small, powerful sources of light that illuminate when electrons move through semiconductor materials. They shine in only one direction, produce a small fraction of the heat of fluorescent and incandescent lights, and lasting longer than other types of lighting.Energy Star, a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy, labels LED lights that meet its energy-efficiency guidelines. Although LED lighting design creates efficiencies, poorly designed LED lights do not meet the potential of the technology. Energy Star guidelines require that LEDs consume at least 75 percent less energy than incandescent bulbs and last 15 times longer. In addition, the bulb must turn on instantly.LED low energy-usage saves money in utility bills. As of 2011, an Energy Star-qualified LED bulb has an average operating cost of $1 per year. That compares to annual costs of $1.20 for an Energy Star-qualified compact fluorescent bulb, $3.50 for a halogen incandescent bulb and $4.80 for a traditional incandescent bulb. In addition, an Energy Star-qualified LED bulb's longer life -- ranging from a minimum of 15 times longer than a traditional incandescent bulb to a maximum of 25 times longer -- means there is much lower turnover of bulbs in your house. (See References 2 and 3) Technological advances with LEDs raise hopes for significantly reducing electricity usage in the United States. LED lighting could cut the electricity demand in the country by 1/3, according to the U.S. Department of Energy. The estimated savings from that adoption would total $265 billion, including preventing the construction of 40 new power plants.
Can Anybody Explain to Me How I Could Instal Interior Underglow(led Lights) to My Car W/o the Cigare
Just run wires straight from the battery for positive and negative1. doesn't ohm's law applied to every thing? [closed]Ohm's law specifically deals with the relationship between direct voltage, current and linear resistance in the form V = IR. For AC circuits it can be generalised to V =IZ where Z is a complex impedance.Transformers convert an alternating primary current into an alternating magnetic field in the core which is then converted back to an alternating voltage in the secondary coil - This effect was demonstrated by Michael Faraday. (Google Faraday, transformer) He showed that the input and output voltages where connected by the turns ratio. For a 100% efficient transformer we get:We must also apply the conservation of energy rule - you can not get more out than you put in. Given that there will always be a loss of energy (heat, noise etc.) the power output will always be less than the power input. always greater Iin * Vin > Iout * Vout (Power in is always greater than power out)If a load is connected to the secondary coil a current will flow. The transformer will react by increasing the primary current in line with the transformer turns ratio in order to maintain the power in to power out relationship.A filament bulb works by heating the filament to a high temperature. Most of the energy used is radiated as heat rather than light, making this type of bulb inefficient. The colour of the light is determined by temperature. (Google black body radiation, Stefan-Boltzmann law).'Energy saver' bulbs use a gas discharge lamp and phosphor coatings to produce light. (Google - Electric discharge in gases) The current passing through the reduced pressure gas excites electrons directly which then jump from one energy band to another before decaying and emitting a photon. (Google - Planck-Einstein relationship) This means that they generate light energy directly without the need to generate lots of heat energy. This makes them more energy efficient that filament bulbs for the same power input. Hence the term 'energy saver.'LED lights (Google band gap, LED) use a similar principle (electrons jumping from one level to another) through a PN junction in a semiconductor.This is more efficient than gas discharge lamps giving LED lighting more lumens (light output) per watt.2. Sleep Peacefully at Night: How CCTV Keeps Businesses Safe in the DarkNight vision cameras were once the standard for the military, scary movies, ghost hunting, and those energetic wildlife enthusiasts. Nowadays, nearly anyone can make use of the technology, especially when protecting business properties. Night vision technology is instrumental when it comes to business security. Several burglaries and attempted break-ins occur at night, and there are many things you can do to improve your business's nighttime security. For example, installing motion-sensitive lighting and night vision CCTV cameras are the most feasible solutions to help you sleep peacefully at night. CCTV keeps businesses safe. Several surveillance cameras are motion-sensitive and can send alerts when movement is detected. You will instantly know if someone is trying to access your facility without your permission. Yet, typical cameras can not see in the dark, so they can not always pick up motion and send you the essential information you need. This is where the night vision comes in. So, how does it work? Infrared, or IR, is the most common type of night vision popular in outdoor security cameras. This kind of technology is brilliant; it can flood an area with light invisible to humans, but the camera's lens has no trouble picking it up. A possible intruder would see complete darkness while the camera would film in near-perfect clarity using the IR light produced. Humans cannot see IR light because it has a longer wavelength and frequency than normal light that's visible to the human eye. Red is the color with the longest wavelengths visible to humans, and infrared means 'below red'. On most infrared cameras, you will see a unique configuration of bulbs being used. Higher power infrared LED lights are positioned around the outside of the camera lens. IR is used for several different filming purposes and is typically used for wildlife filmmaking. This is because the invisible IR light does not bother the animals as they cannot see it. This makes for a very secretive, nocturnal filming opportunity. Another type of night vision filming technology exists. It's not something commonly used in homes, businesses, or even professional security cameras. Image intensification tubes are used in night vision goggles to collect and significantly intensify all available light, including infrared light. This allows the wearer of the goggles to see in low-light situations or even in total darkness. When an area appears to be completely pitch black, it never truly is. There usually is a source of light, even if the human eye finds it difficult to spot. The light entering the goggles is converted into a green tint, making people's eyes shine brightly in the image created, as human eyes are most susceptible to green light. Night vision goggles that employ this technology are most likely used in military and law enforcement operations. Night vision is instrumental in security cameras since it allows the camera to detect motion more adequately, thus picking up movements by an intruder with ease and alerting you immediately. Although, there can be occasions where you (or the police) cannot get to the location in time, and the intruder makes a getaway. If this happens, your night vision cameras become even more valuable. The clarity of the footage that they can record with IR light and night vision technology means that perps can be more easily identified and arrested. The footage then becomes very useful as evidence. In contrast, a standard surveillance camera would pick up a blurry image in poor lighting or absolutely nothing at all in the pitch dark. Most night vision CCTV cameras also come with extra features and functions to further enhance the footage's quality and clarity. These include: Capture Faces, Number Plates, Etc. With This Technology With this new technology, you can capture faces, license plates, and many other details to provide to the authorities. A lot of activity takes place under cover of darkness, and night vision cameras can help you keep a sharp eye on what is going on. This is very useful in legal cases, investigative matters, or just to provide everyday proof of suspicion.3. Why paintball marker is better?1. They are all under 2 lbs. You would never be able to tell the difference, though. 2. Egos are technically more air efficient but efficiency among high ends nowadays is such a dead topic because they are ALL more efficient than anyone could possibly care. 3. Better settings? Like ease of settings? Because they all have the same tourney modes. Egos are probably easier because they have an LCD screen instead of LED lights. 4. They are all easy to maintain but Egos are a little faster in the maintenance dept (less o-rings to lube). 5. I prefer spool valve guns over poppits, so i like the DM's more. Never shot an NT but i can not imagine it feeling too much different than a DM.
How to Add Turn Signals and Wire Them Up
How to Add Turn Signals and Wire Them Up Want to add turn signals to your hotrod? You should! It's not that hard... 3. Make your own switch system. (It's easy!) Factory switchMost of you will have a hotrod that uses a steering column that has a turn signal switch built in. What you need to do is find the wiring diagram for the vehicle the column came from. Just find it on the internet. It will show you which wire should go where... Some of you will have a hotrod that does not have a factory switch in the column. The easiest way to add on turn signals without a factory switch is to use an aftermarket unit like these universal types: You can get them at places like Napa or here: However, some people do not like the look of it so they want to hide it. It's easy to put that unit under your seat, by the shifter, etc. Still others would like to run their turn signals with a simple toggle switch on the dash. There are two ways to wire it in... -Wiring in turn signals that have their own seperate rear bulbs. -Wiring in turn signals that share the rear bulbs with the brake and tail lights. Let's start with the first... What you will need is a toggle switch and a flasher unit. For the toggle switch you will need a SPDT (Single Pole Dual Throw) toggle switch. They look something like this: They work something like this: You can get them at places like Napa or here: Next you need a 2 pin flasher unit. They look like this: You can get them at places like Napa or here: NOTE: If you want to run LED lights or bulbs, you will have to run an electronic flasher unit. You can get them at places like Napa or here: Now, wire them in like this: Ok, now to wire in turn signals that share the rear bulbs with the brake and tail lights, you have to get a little creative... What you have to do is make the brake light wires and the turn signal wires combine in a way that the turn signal wires can override the brake signal. There are complicated ways to wire in multiple relays to do it, and aftermarket units that will do this but there is an easier way... A quick and cheap way that works just as good is a tail light wiring converter for trailers. They will combine the brake wiring and the turn signal wiring so they will work. You can get them at places like Napa or here: Some have the tail light wire running through them (4 wire into 3 wire), and some do not (3 wire into 2 wire). It does not make any difference, as the tail light wiring is not affected. All you are worried about is the brake and turn signal wires. Note: Do not try to run them with LED's. The converters are not made to run the extra voltage. Just stay with regular bulbs and it will work great. Now wire it in like this. (This version uses a 4 wire into 3 wire converter. For a 3 wire into 2 wire converter, just take the tail light wire past it.) No problem, you just need another toggle switch and flasher unit. The toggle switch is different than the other though... For the toggle switch you will need a DPST (Dual Pole Single Throw) toggle switch. They look something like this: They work something like this: You can get them at places like Napa or here: Now you need another 2 pin flasher unit. Now wire them in like this: Return from Turn Signals to Hot Rod Wiring Return from Turn Signals to How-To-Build-Hotrods1. what household items contain led lights?Desk top computer front panel and its enthernet card beside the plug input ; DVD player; Game device : remote control has IR LED in its front ; USB drive ; monitor front panel ; printer panel ; LED bulb ; LED tube ; garden solar light ......so many2. No video imput when computer turns on?Your computer is not running POST. As it's a fresh build, you need to double-check the power connections (there should be TWO of them) from your power supply to your motherboard. If all the connections look good, the most likely problem is a dead power supply. Even if the power supply appears to turn on, it can still be dead. In other words, LED lights lit and fans spinning does not mean that your power supply is good.3. What's the difference between fluorescent & led lights for aquariums?Theres lots of difference. The main one would be that LED last longer, penetrate deeper, and uses far less energy. Beyond that the type of lighting, colour, and effects on fish and plants depends entirely the type of LEd and bulb used. Theres lots of variations between different fluorescent or LED lights. I have some LED's on one tank that are a slightly daylight yellow colour. They grow my plants well. However I have another equal sized stip of LED that wouldnt grow anything if I tried. I use them as moonlights. So in the end it just depends on what the individual person wants..

LED Safari: Teaching People to Make Solar Lights
There is a proverb I'm sure you've heard before that says "give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime." LED Safari is doing just this, going beyond providing affordable solar lighting to teaching people to make solar lights themselves. Today there are many organizations that are spreading solar power to rural areas in developing countries. The new range of options and prices has made solar power increasingly accessible to poorer households. However, there is still a barrier to the poorest, who are unable to take the risk of investing in a solar lamp that could break. They feel safer continuing to spend the same amount on kerosene, even if the lamp would be cheaper in the long run.LED Safari began in 2010 with a plan address this concern. They train people to make their own lamps out of the main components. This not only allows people to be creative in the design of different lamps, but also ensures that the lamps can be repaired if they should break. The model also provides people with valuable skills and empowers them to create unique businesses making different kinds of lighting products, or repairing them when they break. In addition, solar lamps can be made out of just about anything, so this program is promoting a new kind of upcycling.To date, LED Safari has trained 300 people and produced 1,000 lamps in Rwanda, Uganda, Kenya, Tanzania and India. Their program is providing skills, creating new entrepreneurs, and making solar power more accessible to the poor. LED Safari also conducts workshops in developed countries for schools, companies and other organizations interested in learning about solar power or looking for a great team building activity.

Does My RAM Need LED Lights?
No... ugh... IT WON'T GO FASTER IF YOU PUT LIGHTS ON YOUR RAM. You need to put a clock going at a fast speed that's also small next to the processor then that should make it figure out "stuff" faster.1. How much would we really need to do to slow or stop AGW?"Given the scale of the problem, your sensible minded people believe, CO2 is causing the only sensible thing to do is to just about eliminate the use of fossil fuels. This could easily be accomplished if believers simply limited there activities to the basic necessities." I disagree with the statement. This statement presuposes that energy is the same as hydrocarbons. It also sounds like a statement from the sort of person who claims that it would be useless to reduce our consumption of hydrocarbons because of China and India. We need to cut our total CO2 emissions to zero. Any time frame would be a compromise. We need to come up with a plan with little or no pain, or the public will not accept it. Unless someone can get cold fusion to work, we should probably do as scientists suggest, and reduce our fossil fuel consumption by 80% by 2050. This question is moot because industry only produces products for personal consumption. Given that we need to reduce our fossil fuel use by 100%, no. It has to be done by a combination of efficiency and new energy. Why use tungsten filament light bulbs, when LED lights are much better than tungsten filament bulbs, or even compact fluorescent bulbs, or be the sole occupant of the largest SUV on your way to work. Nuclear power must be used, at least as a transitional energy source. An wind farm that is built instead of a nuclear power plant is wasteful, as it could be built instead of a coal plant. When we no longer use fossil fuels, then we can think about replacing nuclear power with solar or wind power.2. Are LED lights enough to help plant growth?Is it far red light? Than no. It needs to be red light3. Where do i hook up wires for cobra eyes by pilot LED lights?into a fuse, they have kits at autozone and stuff for like 1.50. But that's the best way to do it. oh yeah, your fuse box should be on the driver side on the side. On the box it will show you the empty places that you can insert a fuse. Do not forget to ground the ground wire to metal on the car.4. Can you see LED lights at night? when they are off?Not that often5. How do I keep my philodendron alive through the Winter?First, try to situate it so that it is blocked from the northern wind...up against a wall is ideal. Then, wrap the exterior of the pot in whatever insulation you have: leaves, wadded news paper, old egg crate/foam, styrofoam, etc. Secure it with twine or wire. If it's not already done, mulch the plant heavily with a good hardwood mulch. Not critical, but this will help. Then drape xmas lights around the tree and pot. Lower is better as heat rises and you want to keep the roots alive (leaves will probably drop off as w/all plants that go dormant in cold weather). Do not use LED lights, and only plug them in at night. Finally, wrap the whole thing in a plastic tarp...and old shower curtain works fine. Secure it with clamps of some sort...the office "bulldog" clamps work fine. I would do this only at night, though, or when you know it will be cold (under 40) all day. Make sure the soil is moist (not soggy) beforehand, too.
Pwm Rgb Controller with Rf Remote for Dc Led Lights
Dimming LED lamps smoothly without flickering is a very complicated technology since LEDs are different from traditional incandescent and halogens. PWM (Pulse Width Modulation) is now an ideal solution for controlling LEDs especially DC LED lamps. LED dimmer for mono lamps and RGB controller for RGB lights with PWM signal to control connected LED lighting enable smooth brightness, RGB color, dynamic changing patterns adjustment and color/scene storage. The PWM frequency is adjustable with low and high options, and the higher the frequency is, the more smooth the dimming will be. PWM RGB LED controller with low frequency will not cause the buzzing noise of the power supply and can be suitable for home decorative lighting control. Some special applications which require ultra smooth and stable dimming control without any flickering such as filming lighting and hospital lighting will require ultra high PWM frequency. For DC LEDs, the controller is designed with DC input and output and requires a AC-DC power supply. It is available with both constant voltage and constant current versions to fit different lamps such as LED strip, wall washer, downlight, and panel light. Some PWM RGB controllers are stand-alone ones that do not require a control units. But for smart lighting, a control unit is better to provide more functions. The unit will send signal to the controllers and many types of control signal are available including RF/WiFi wireless, DMX, DALI and 0/1-10V. All these signals will be decoded by controllers and converted to PWM signal. The controllers shall be designed in accordance with corresponding control protocol of RF, DMX, DALI and 0/1-10V in order to receive the signal. Traditional control units are push switch (toggle style or rocker style) and rotary knob. They are simple and easy enough to operate by just click or push. Full touch panel is a new style that enables all operations to be executed by touching and it can perfectly installed into existing wall boxes. PWM RGB LED controller is suitable for home decorative lighting control , they are safe and reliable to provide abundant functions with smooth dimming and running modes. You can choose the proper frequency and control unit based on your requirements.
