A SOLAR POWERED MOBILE PHONE

Step 10 Another way of doing this without cutting holes in your phone or anything and some other cool ideas i have with solar panels

instead of adding a panel to your phone what you can do is get a protective phone case like in the picture below.mount the panel inside the phone case, now all phones have a charger point usually at the bottom of the phone all you do is connect the solar panel to the end of a phone charger but put a blocking diode in between the panel and the charger end. then just plug the chargeing tip into the bottom of your phone and it charges. it may not register as charging as its low ma's but it will charge your phone.if you think that it is not charginf your phone then you can put a 200k resistor on the ground connection between your panel and your charger plug.also phones that have a mini usb connection on them sometimes require you to connect the data- cable to the ground for it to register that a cable is plugged in to it.you can search for pinout diagrams on the internet for your specific phone.but as we are dealing with low power solar panel the phone will never register as charging as its too low to detect it, but i can tell you it will charge yourphone regardless what way you do it.

if you want to do something else similar then you can buy a bigger version of this paper thin mirrowed finish solar panel and attach it to the back of your laptop screen so it charges your battery when your not using it and when you are using it.and if you wanted to go the whole hog you could even buy long thin solar panel strips and insert them inside your screen where the florescent tube is which lights up the screen and collect free energy that way and put it back itno the laptop battery.or use it to power usb sockets etc.or even connect a female usb cable to the soalr panel on the back of your laptop screen adn use it to charge mp3 palyers and things instead of using the usb socket on yout laptop.

Great idea. Very neat finish. My question is: How long does it take to charge the phone using this solar panel? Regards.

well considering i only charge it during the evening when im at home relaxing i do have to use the mains charger about once a week for about 15 minutes.it nearly sustaines the phones power needs.this is the first stage design. i will buy another panel that will completley keep my phone going withut me even having to charge the phone again.but it costs £25 and i dont really need to do it as i know it will work as i have donw the maths. my other idea i had is to use a solar powered charger.like a ipod docking station with speakers. the solar panel sits on the desk during the day charging the internal battery, then when you get home all you do is place your phone on the holder and it charges the phone from the built in battery on the solar panel.what do you think. i have a soalr panel to do that project but its slightly too big so im going to wait untill i have another panel and then make the solar panel docking charger for my phone.
