This is where truthfully you need to migrate to pic micro and possibly look at compilers such as offered by proton Smart which incorporate Sony IR in and Phillips RC5 codec`s But it is the safest particularly if you intend to use this for Security aware applications Consider also Bluetooth and wifi as another strong point now as this is leading into the newest

of technologies with reference to tomorrows world Here you might choose to use other encryption techniques and incorporate as an extra facility for example RF ID which relies on RF and power generated form the remote transmitter to your key with encrypted codes, sent once power up Look into all of this if this is what you want to do also bare in mind that like any security system and very similar to RF Id which they are having massive problems with regards travel cards etc in the UK at the moment, particularly one day charges for all over London via tube rail and bus services If not done correctly and with no apparent override system, if this does go wrong j which it I always will, just like any other electronic appliance etc Like any other data, Data can be and does get lost, equipment may malfunction so you need to take all of this into consideration Total cost to British Rail some £8. 00 just for me Consider this of you will for some 20 000 plus commuters both foreign and national on a daily basis It`s a major catastrophe to say the least and why Too much of a rush to install this system and thought It would be perfect Nothing ever is ! In other words instead of trying to get people to break the system They didnt bother This is exactly what I mean by Dont listen, never do and always think they know better, it pays to listen to all types of people no matter how big or how small Someone will always find a way through Thats...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
