Are you interested in learning electronics design? This thread is an avenue for students, hobbyists, do it yourself,electronics technician to learn the rudiments of how electronics circicuits are design. The basic software tools needed in this thread are easily available on the internet for free. The thread will be made as much interactive as possible and you are free to make your contributions, comments and you can even ask question if there are any. The thread will be made to be continuous in as much as there are contributions and flow of information. Circuit ideas can also be shared if you have any. Nothing will be hidden and every detail process involve in the design process will be shown through the use of multimedia such as picture, charts and video if there are any. Circuit diagram, pcb lay out diagram, 3D visualization and prototype picture will be displayed using jpeg picture format.
The software that are used in most of these design are classified as followssad 1)The schematic capture software for designing the circuit diagram
(2)The circuit simulation software for simulating the circuit, to see how the circuit behave in real life situation
(3)The pcb design software for designing the electronics components layout and path for current flow. This is achieved either through autorouting or manual routing
(4) The programming software for writing code for embedded system if you are using microcontroller or eeprom in your circuit
The hardware that are needed are(1) analogue or digital multimeter(2)oscilloscope if you have access to any(3)soldering iron/ rework station(4)12v, 6v battery or desktop power supply.
Project topic will be for a month, and within this period you are to make your contributions, ask questions ,build your own version of the hardware. You can only learn through building. Engineering is all about building things.wherever possible it is much better to learn by doing things yourself than by reading about them.
You will find in this thread a lot of suggestions, ideas you can do yourself. I hope you will all manage to do these things as you go along. So let get started as we delve into world of electronics together.

PROJECT FOR THE MONTH OF NOVEMBER

MICROCONTROLLER BASED RADIO REMOTE CONTROL

CIRCUIT IDEA: The circuit is designed to switch on and off any electrical gadget using radio technology . The circuit can switch on and off about 8 different equipments in the house. So you can easily incorporate it into your home wiring.it consists of transmitter and receiver units
An Rf module is used and this is a small electronic circuit used to transmit, receive or transcieve radio waves on one of a number of carrier frequencies. The carrier frequency selected is 433mhz.

APPLICATION
(1)Wireless home automation eg automatic control of lamp, tv, borehole pump, fan etc
(2)Industrial remote control
(3)Wireless alarm system especially in cars
(4)Garage door openers

ADVANTAGES
They are often used instead of infra red remote controls as they don't require line of sight operation
They can operate up to 1km( this depend on voltage applied to the transmitter)
TOOLS NEEDED:
Software: (1) proteus version 8-- as schematic capture and for simulation
(2)PCB wizard drawing the components lay out and current path
(3)Proton basic for writing the code for the microcontroller

Hardwaresad1) pic programmer
(2) Multimeter

Nice one,

This is encouragement for those interested in electronics design.
Is the copper pour you used for ground continuous?

Copper pour is not yet continuous. I will use jumper to connect to ground(-) when soldering

Thanks for taking your time to put us through this
I pray it will be successful
I can't view the cct dias clearly besides,I may want to refer to it when building my own,why can't u make it downloadable also.
Concerning the Rf device you intend to build,it's a two way things I supposed
Any electronics that will work with it will have inbuilt cctry to send and accept the signal,so I doubt how we can incorporate it into existing device without changing its functions.
Don't forget to tell us where we can buy our discrete components
I hope oscilloscope is not expensive sha?
Anticipating in earnest in learning from you,

I will try and reupload the circuit diagram again. I'm still on where to upload the entire files for this project, may be on 4shared or dropbox. The RF. Module are of two type, the transmitter and receiver module.they seperate units. So u need to build an encoder and decoder circuit that send and receive digital codes. The encoder( transmitter side) and the decoder(receiver side) uses a microcontroller. Always come back to this thread as I will be updating it. Thanks

DESIGNING A CIRCUIT
A few years back it was a haunting task to design a project solely with gates, relays , resistor etc but due to progress in electronics, with CAD program electronics circuits can be designed within a twinkle of an eye. So nowadays to design any electronics circuit from scratch just lay your hand on any electronic CAD software. There so many of these software on the internet, some are free while you are to pay for licence for others. And since we are in third world country , the prices of some of these software are far too high for an average person unless one is using for commercial purpose. So download the crack version of the software mentioned below . To start designing you need the following software.

(1) Schematic capture software: for drawing your circuit diagram. some of these software can also be used for simulation. So you need to download PROTEUS 7 to version 8

(2) Pcb design software: for designing the printed circuit layout pattern if you are not assembling your circuit on breadboard. Though proteus also come with pcd design software called ARES, but its somehow comlex to use. So I recommend pcb wizard

(3) Picbasic compiler: for writing your codes in basic language for pic microcontroller. From basic language you can then move to c language. As a beginner start with basic. We need this because we are using a microcontroller in our circuit

Download these three software and install
Re: Electronics Circuit Design From Concept To Implementation by acorntree(m): 6:37pm On Nov 14, 2014
If you have been able to download all these software let us start .
Re: Electronics Circuit Design From Concept To Implementation by baba11(m): 10:00pm On Nov 14, 2014
OK sir...give me some times to do these

Till tomorrow
