Looking for a way to tell how far you are in your garage? Tired of tying tennis balls to your ceiling only to have your dog get excited and pull them down? Looking to get rid of your boring old reflector? Have at least a basic idea on how circuits work and want to try something different? If you answered yes to these questions, then this instructable is perfect for you. In it you will be able to do build and use your infrared transmitter and receiver just by using a small list of parts and some time to build it!
At the end of this project you will be able to detect your car as it approaches the wall inside your garage; the project will then tell you when to stop by turning on an LED thus letting you know when your car is safely inside your garage.
The goal of this project is to use a timer in an oscillating mode so that it generates a 38 kHz square wave. This is done so that the receiver will detect the signal using a IR receiver sensor that is tuned to detect that frequency and turn the red LED on. You might be asking yourself how this works. The answer is fairly simple, this will be similar to how your remote control works. When you press a button it sends an infrared signal to a receiver built into your TV; the TV then carries out the command you send it.
This works very similar to it, albeit, a bit more dumb. Tools For this project, there will not be any tools needed. Instead, everything will be built using breadboards and through-hole parts.
Parts Here is a list of all the parts needed. For your convenience I have provided links to for each part. Just an understanding of pin layouts of the timer, infrared receiver, and the voltage regulator. If you are unsure what goes where, then you can follow the links for the parts I've provided, or Google them especially if you decided to go with parts other then what I've suggested. Powering the Circuit Power will be supplied by a regular 9V battery attached to a 5V regulator with bypass capacitors.
The design can be modified and changed to make the timer more efficient, but these were all that were available. This receiver was chosen so that it would reject all other frequencies, but the 38 kHz, including visible light.
The Timer The main idea to understand is the timer is in a-stable configuration. The ohm resistor next going to the IR LED limits the current out of the timer so we do not destroy it when driving the IR led; the 10K resistor ensures that the timer is not in reset.
If it's difficult to follow what's going on in the circuit schematic in the previous step, then I've created a simulated version of what should be going on. Note, that you can design this circuit anyway you see fit. This is my first time using Zero to Breadboard Simulation, so things may be a bit crowded or not as optimal as I would have normally laid things out.
I've also changed the notation of the capacitors, for those that may have been lost, nF is equal to 0. The second image is an actual layout, it maybe hard to see what's exactly going on, but it will give you a general idea. I've also moved the 5V regulator to the other board to help in troubleshooting when I was building the circuit, so it is not showing in the Zero to Breadboard simulation.
Be careful to follow pin diagrams for all parts! It is important to note what all pins do what. If you plug something in incorrectly it WILL burn either the part itself up or create a dead spot in your board!
Google the part number found on any of the parts listed in to see what they are if you are unsure or didn't keep any of the packaging that your parts came in. This is the more simple of the prototyping to do. This circuit contains only 5 components should be easy to place. Again, feel free to change your layout to make it more optimized. I played with several different layouts and ultimately decided that this would be best for me.
The final outcome depends on the parts that you chose. If you chose to stray from the ones listed, then you will have to recalculate what needs to be changed. The boards will also need to be adjusted so that they will properly see each other when you are pulling your car into the garage. Here is a demo of the project working. Draw Backs and Improvements This circuit is always on, therefore your battery will go dead and will need to be replaced at least once every two months.
The goal later on will be to change the circuit so that it can detect ambient light and turn on when it is needed. I found this project while working on an assignment for my English technical writing course at Iowa State University College of Engineering. The assignment was to chose an instructable that was centered in our major and see if we could improve it's layout and design. Reply 5 years ago. Hi , how can i modify the very same design to transmit and recieve signals 20 m away, how do i determine the frequecnies etc.

FM Transmitter Circuit
While they may not share the same prestige, history or reverence as studio mics, wireless microphone systems are ubiquitous in modern communications. Far beyond the realm of music-making these mics are integral for beaming voice to ear, used in everything from filmmaking and broadcasting to journalism, business and education. In some instances, wired microphones are inconvenient and impractical, and in others, their use is simply not feasible. Since then, a huge amount of headway has been made — in the modern age, wireless mics are affordable, reliable and versatile. Wireless microphone systems are comprised of three fundamental components: the microphone, the transmitter, and the receiver. These will usually have a transmitter built into their body, making them quick and easy to set up and move around with. As the name suggests, these are worn on the head, often over the ear, while a discrete arm positions the capsule very close to the mouth.
In electronics and telecommunications a transmitter or radio transmitter is an electronic device A transmitter and a receiver combined in one unit is called a transceiver. An electronic oscillator circuit to generate the radio frequency signal. Experimental television transmission had been conducted by radio stations since.
In electronics and telecommunications a transmitter or radio transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current , which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio , such as radio and television broadcasting stations, cell phones , walkie-talkies , wireless computer networks , Bluetooth enabled devices, garage door openers , two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term transmitter is usually limited to equipment that generates radio waves for communication purposes; or radiolocation , such as radar and navigational transmitters.
The present invention relates to a television transmitter, a television transmitting method, a television receiver and a television receiving method. More particularly, the invention relates to a television transmitter and a television transmitting method whereby a hyper text data signal associated with television broadcast is prepared and transmitted, as well as to a television receiver and a television receiving method whereby the transmitted hyper text data signal is received and processed. Systems capable of digitally transmitting the television broadcast signal via satellite broadcasting or communication satellite to households are getting widespread acceptance. Such systems each offer the household a very large number of TV programs carried illustratively by nearly 80 channels to choose from. With the ever-growing number of programs they can transmit, these systems propose transmitting along with the programs an electronic program guide EPG allowing users to choose desired programs easily.
Here we are building a wireless FM transmitter which uses RF communication to transmit the medium or low power FM signal. The maximum range of transmission is around 2 km. FM transmission is done by the process of audio pre amplification, modulation and then transmission. Here we have adapted the same formula by first amplifying the audio signal, generating a carrier signal using an oscillating and then modulating the carrier signal with the amplified audio signal. The amplification is done by an amplifier, whereas the modulation and carrier signal generation is done by an variable frequency oscillator circuit.

Контакт был установлен. Жертва ощутила прикосновение смерти, и началась совершенно иная игра. Беккер мчался, не видя ничего вокруг, постоянно сворачивал, избегая прямых участков.
Халохот прокручивал в голове дальнейшие события. Все было очень просто: подойдя к жертве вплотную, нужно низко держать револьвер, чтобы никто не заметил, сделать два выстрела в спину, Беккер начнет падать, Халохот подхватит его и оттащит к скамье, как друга, которому вдруг стало плохо. Затем он быстро побежит в заднюю часть собора, словно бы за помощью, и в возникшей неразберихе исчезнет прежде, чем люди поймут, что произошло. Пять человек. Четверо. Всего трое. Халохот стиснул револьвер в руке, не вынимая из кармана.

Говорите, - сказал он, быстро проглотив пирог. - Джабба, - проворковала женщина в ответ. - Это Мидж.
Давайте же, - прошептал Фонтейн. - Вычитайте, да побыстрее. Джабба схватил калькулятор и начал нажимать кнопки. - А что это за звездочка? - спросила Сьюзан. - После цифр стоит какая-то звездочка.
Он схватился руками за боковые стороны проема и, одним движением вбросив свое тело внутрь, тяжело рухнул на лестницу. Халохот услышал, как где-то ниже тело Беккера упало на каменные ступеньки, и бросился вниз, сжимая в руке пистолет. В поле его зрения попало окно.
