Make a Hi End RF Remote Control Circuit
Building a hi-end remote control device using very few components today looks pretty plausible. The proposed remote control light switch circuit idea provides you with the opportunity of building and owning this amazing device through simple instructions. Moreover the unit provides a 4-bit data to be exchanged between the transmitter and the receiver modules.
This Hi-tech remote control light switch enables you to control four individual lights or any electrical appliance for that matter from any corner of your house remotely using a single tiny remote control hand set. Build the “amazement” right on your workbench.
Imagine switching a light, a fan, washing machine, computer or similar gadgets from any corner of your room without taking a step! Doesn't that sound great? Controlling a particular gadget remotely through a single flick of your finger definitely feels very amusing and amazing too. It also gives you the comfort of doing an act without moving or getting up from a particular position.
The present circuit idea of a remote control light switch enables you controlling not only just a single light but four different electrical gadgets individually using a single remote control hand set.
Let’s try to understand its circuit functioning in details.
Circuit Description:
I have already discussed the wireless control modules through one of my previous articles, let’s summarize the entire description yet again and also learn how simply the stages may be configured into the proposed unit.
The first figure shows a standard transmitter module using the RF generator chip TWS-434 and the associated encoder chip the HOLTEK’s HT-12E.
The IC TWS-434 basically does the function of manufacturing and transmitting the carrier waves into the atmosphere.
However every carrier signal needs modulation for its proper execution, i.e. it needs to be embedded with a data that becomes the information for the receiving end.
This function is done through its complementing part – the HT-12E 4-bit encoder chip. It has got four inputs, which can be triggered discretely by giving them a ground pulse individually. Each of these inputs produces coding which are distinctly different to each other and become their unique signature definitions.
The encoded pulse from the relevant input is transferred to the IC TWS-434 which carries forward the data and modulates it with the generated carrier waves and finally transmits it into the atmosphere.
The above operations take care of the transmitter unit.
The receiver module does the above operations just in the opposite manner.
Here, the IC RWS-434 forms the receiving part of the module; its antenna anticipates the available encoded pulses from the atmosphere and captures them immediately as they are sensed.
The captured signals are relayed forward to the next stage – the signal decoder stage.
Just like the transmitter module, here too a complementing device the HOLTEK’s HT-12D is employed to revert the received encoded signals.
This decoding chip also consists of a 4-bit decoding circuitry and their outputs.
The received data is appropriately analyzed and decoded.
The decoded information gets terminated out through the relevant pin-out of the IC.
This output is in the form of a logic high pulse whose duration depends on the duration of the ground pulse applied to the encoder chip of the transmitter module.
The above output is fed to a Flip-Flop circuit using the IC 4017, whose output is finally used to switch the output load via a relay driver circuitry.
One such flip/flop idea is shown you may construct four of them to access each of the generated 4-bit data discretely and control four gadgets individually.
Whether you use it as a remote control light switch or to control many more appliances……the option is all yours.

How Amazon to ship Android based gaming console by years end
Online mega-retailer Amazon may be planning to release an Android-based gaming console by the end of the year, if rumors prove correct.
Citing "those ... who have knowledge of the in-development hardware," Game Informer claims Bezos & Co. may be readying the device to ship by "Black Friday" – the day after the US Thanksgiving holiday, traditionally the start of the holiday shopping season, which this year falls on November 29.
Details of the plan are virtually nonexistent, but this isn't the first time El Reg has heard murmurs that Amazon may be planning to broaden its hardware line beyond its Kindle e-readers and tablets.
In May, The Wall Street Journal reported that Amazon was operating a secretive facility in Apple's hometown of Cupertino, California, known only as "Lab 126," where it was working on at least four hush-hush hardware projects.
Two of those were said to be Amazon-branded smartphones, a perennial topic of discussion among rumormongers. A third was thought to be some kind of set-top device for streaming Amazon Prime video (Chromecast competitor, anyone?).
Details of the fourth project were less clear. The WSJ reckoned it might be some sort of standalone streaming audio player, but those are a bit passé in the age of the smartphone. Could an Android-powered gaming console be the answer?
Maybe, but if Amazon is planning to get into the gaming biz this Christmas, it will face tough competition. Both Microsoft and Sony are expected to launch their next-generation consoles in the same period, and many customers have already preordered one or the other.
Amazon's wouldn't be the first gaming device based on Android, either. Nvidia released its portable Shield device at the end of July, and sales of the Kickstarter-funded Ouya microconsole have been modest.
Still, there's reason to believe Amazon may be able to outflank these competitors in the Android gaming market, owing to its strong brand and its mature sales infrastructure.
The Amazon Appstore already works on most current Android devices as well as Kindle tablets, so adapting it for an Android-based console should be trivial. Earlier this week, Amazon opened its developer program to web-based content in addition to native apps, giving Appstore customers access to offerings from a wide range of developers. And when your Reg hack checked on Friday, Amazon's top ten bestselling apps were all games.
