Hello everyone Techsavvy here ,
it been awhile since I posted anything ,
and I Thought I owe it to my Awesome subscribers to post something I'v been working on ,
Thanks again guys for your support ;-)
and fellow users
so to start off by saying a couple of things ,
well for starters I wanted to make my own mint tin Version of a cellphone charger that is powered by both sun and battery ,
I know there's few Idea's out there and there all great ,
but I wanted to see if I could make one cheaper and explain in a way that's easy for everyone to understand ,
Second I wanted it easy to make so that anyone could make it , even those who don't have that kind of know how ,
and three I wanted to make it easier by telling others were to find the altoids tins or other type of mint tin ,
yes that's a problem were I live not to mention I don't have radio shack either I know scary right ,
and lastly I wanted it to be able to replace the battery anytime I needed instead of waiting for it to charge all the time ,
so with that said lets go make are own Smart mint .
Step 1: Getting What You Need
OK so here's a list of thing's you will need ,
Things to buy .
1x 3 volt solar cell , ebay or buyincoins , I got mine from buyincoins for about $ 2.00
1x 1.5 volt to 5 volt boost module , you can get These on ebay or buyincoins , for about $1.50 to $2.00 .
1x Rectifier diode any will work fine , you can buy these on ebay or for a $ 1 for 100 .
1x switch I used a rocker switch , but you can choose what ever you have on hand , this only costed me $ 2.00 for 10 on ebay .
1x (AA) Battery holder and rechargeable battery , this was bought off ebay as well for $ 1 for holder and battery two for a $1,
1x Altoids tin or other mint tin , since were I live its very hard to find mint tins so I used a Sucrets tin , $2.00 found at dollerama or pharmacy or at walmart .
1x 10 or 25 volt capacitor . ebay as well
Tools and materials
Note some of this is optional you can use what ever tool's you have handy ,
Soldering gun / optional
contact cement / optional
double sided tape
electric tape ,
piece of solid package foam / I used a piece that came with the module ,
Dremel or sharp Knife ,
gloves and safety glasses ,
Please note I'm not reasonable for any Damage or harm to one's self , please use all recommended safety percussion's and be safe .
Step 2: Get the Case Ready
OK to start were going to need to cut out and drill the holes for are switch and usb port and the solar cells wires ,
to do the take a marker a trace on both sides of the usb and do the same with the switch ,
then make a mark on the top of your lid in the middle that were the wires for your solar cells will go in ,
once you've done that go ahead and cut out your hole for usb and switch and drill the hole for the wire's ,
now that that's done you can fit the parts that you going to put in to see how its going to fit ,
Step 3: Mounting and Gluing
OK now for the easy part ,
take a piece of the foam and cut it to fit the module , not only this will ground it from the case but it will help protect it if the case falls ,
Next take some epoxy and glue the foam to the inside of the tin were the module will go,
Next take a piece of double sided tape and put it on both ends of your battery holder ,
then place it inside the case pressing down firmly ,
When that is done you can put the switch in it place ,
Step 4: Putting It All Together
OK now its time to finish it off,
Now I made a Diagram of were everything is to be connected ,
But i'll put it into words also ,
ok first take your ground wire for your battery hold and solder it to the ground on the module ,
next take the diode and the cap and solder the caps positive to the the black end of the diode ,
then take the ground on the cap and solder that to the ground on module ,
and then take the solar cells ground and solder it to the ground on the module ,
now solder the grey end of the diode to the the off position on the switch ,
and then take the battery holders positive and solder it to the off position on the switch ,
Then solder the modules positive to the on position on the switch .
once done you can glue gun the module to the foam , and glue gun the connections to insulate them from touching ,
then glue your solar cell in place , I used the glue gun to glue the cell and then used some contact cement as a seal around the outside of the cells edge ,
OK your done moving on
Step 5: OK the Specs and the Testing
OK time to test it out ,
First I tested it with a voltmeter to see how the voltage looks ,
as you can see almost five volts it would have been more but I did want to wait for the battery to charge :-) ,
now in the pictures you can see the phone is charging well when plug into the smart tin ,
note if you have a Android phone it will say slow charging when plugged in ,
that's fine it says the same when plugged into the computer ,
now it only took five minutes to charge the phone from 46% to 49% ,
since its winter it to soon to judge how well the solar cell will work ,
but like other's i'v used It should more than keep your battery topped up ,
so the over all project costed me around $7.00 to make .
so there you are now you can make your very own smart tin , Thank you for viewing
P.s IF you have any questions feel free to ask :-)
