smart recycling of E-waste[green-recycling]

Technology for the disabled

Portable personal computer

Introduction Pollution is one of the worlds biggest challenges and is a major contributor to global

warming. e-waste pollution is causing severe health concerns for millions of people around the world,

mostly in developing nations in Africa. Primary and secondary exposure to toxic metals, such as lead, results mainly from open-air

burning used to retrieve valuable components such as gold. Combustion from burning e-waste creates fine particulate matter, which is linked to pulmonary and cardiovascular disease. Toxic chemicals from e-waste enter the "soil-crop-food pathway," one of the most significant routes for heavy metals' exposure to humans. These chemicals are not biodegradable—they persist in the environment for long periods of time, increasing exposure risk.

A smart way to recycle is to reuse the electronics by making new things out of them. E.g. a 3D printer out of two old or dead printers.

I realized I had a strong desire to pass this wealth of knowledge and creative experience to younger people and the society on how they can smartly recycle the E-waste and add value to it while also learning how the systems work.

Basic electronics and there sources

• Light emitting diodes • Resistors• Capacitors• Transistors• Battery clips

• Sources • Radios• Dvd players • Television sets• Printers• And othe electronics

Using visible light to transfer data• We are going to use 8 light dependant resistors and 7 light emitting diodes. Seven segment display. And

4015 14 leg ic which can be found in DVDs or registry display machines. • Data is sent in form of zeros and ones . When the led is on it is a one which activates the circuit. When it is

off it is a zero

Making a 3D printer• This is a printer that can print real objects by slicing a 3D image into layers which the printer can recognize.• We are going to use two rails from the printers that control the cat ledge movement to control the

printing head of our 3D printer. • The head will melt the printing plastic using inductive heating or arc heating using carbon rods.• AdvantagesWill be used in schools by students who do geometrical and mechanical drawing to create real objects of

things they draw. And even print a part they need when designing things they need. Hence this will promote creativity and a large market for 3D printing.

Making a wireless charger and modem

• Electrodynamic induction When an oscillating electric current passes through a coil it generates and oscillating magnetic field. This magnetic field can be received by a similar coil and generate an electric current which can power up other devices. If the oscillation is timed by the transmitting and receiving coil we can even transfer data .,By using frequency modulation.

Remote device control using a phone

• This system will allow as to control our home devices remotely and will help save electricity cause it will be user controlled.

Connecting a keyboard to a DVD to make e-learning more interactive

• The main initiative of this project to simply improve e-learning by giving people the ability to use a computer keyboard for typing on there DVD and even navigating.

• How it works • A DVD remote control uses arrows to navigate and an okay button to accept and we take advantage of this

mechanism by using logic gates to do the pressing for us. So as to navigate a particular character.

Technology for the disabled

• Analog system• A sign language interpreter that will use the movement of the hand to sense the gesture been made and

interpreting it into sound. • Digital system. using glasses with a cameraThis will use a camera to interpret the gestures into sound and will also convert the sound into a gestureThe mouse has a horizontal and vertical roller these rollers will be connected to pulley strands.The pulley will be connected to a glove when movement is created the computer will interpret the gesture into

an audio output.

Just to add on we can also use the same mechanism for the handicapped to drive there wheel chairs using there tang

Info-Pad for blind • A pad for the blind that will help them read books, news and even magazines it will use electromagnetic

induction to generate the patterns required.

• We are also going to modify existing computer key boards with DOTs which the blind can feel so as to enable them type.

• a radio frequency will be sent to trigger a particular letter just like in a teletypewriter.• We will need a radio frequency converter and an old typewriter and an induction pad.

Portable personal computer

• This will help people carry there data anywhere they go. No need for drop box or remote file control which are costly systems

• We install an operating system on a laptop hard drive or on a flash disk which will have a small interface. Like windows mobile. Then we will load it with office packages and programming soft wares .

• This means people will move with there desired computer interface anywhere without loosing there data • This will also help to supplement the shortage of personal computers in rural schools and urban schools

that have a shortage of computers.• This will improve operations in places where there is a shortage of computers .If this project is for field we want to make computer booths where people can access there data and use

internet

Suggested researchSending data over radio waves

• This system will work efficiently if each radio has a unique identification. • We will be able to send data over radio waves by phase shifting the wave. So special modulators will have

to be designed for the radios• Advantage is that you can request for data and it can be sent to you over the radio.
