I have completed this above mentioned project. People have had SMS contl on Siemens/Ericsson/and other phones but they have a modem on them, and comapratively simpler coding is needed. Older nokia fones use FBUS protocol which is their (nokia) own difficulkt protocol made up of innumerable bytes @ 115kbps. Some site

s like give a detailed description on the protocol. also have done commendable work. But all other people have done it with AVR(with larger RAM). I have done it with 256byte RAM on 89S52. I have 4 devices (relays) which can be controlled(on & off). instead i`ll put up the hex code, general ckt and most important ->an excel sheet(which i had made for myslf from sites like gnokii and embedtronics) which explains the FBUS in details. these fbus commands definitely will make life easier (believe me. its a hell xperience to understand the protocol in itself). Thats the reason Rickey`s World is here. complete information and i don`t hide anything i work on. soon i will be posting two projects based on IR remote. 1)As shyam said there is lots of support on FBUS and a li`ll googling will help u on this, but he has failed to understand that he wont find stuff for 8052. Nobody(not even embedtronics. com, which I mentioned) has direct info or the codes for FBUS, which I think I have uploaded in my earlier posts. If I was the stingy "Indian" as Ajay has notoriously christened me, I would have hesitated to even put that up 2)If somebody is there to help u out and he says he will be with u during the hardship, u shud be happy and proud of his company. If I were to give away the code, wheres the learning process. instead I m saying I will help in every which way to let u understand the working and coding. 3)During my development I tried...
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.....
