Hi there everyone ,
I was bored last night and needed something to do ,
so the birth of new project was born ,
I call it micro power 2 go 2.0 ,
now if you seen my last project micro power 2 go the old model you'll now what i'm talking about ,
if you what to see it you can go here https://www.instructables.com/id/Micro-pocket-power-2-go-its-solar-to/
ok so here's whats new about this version ,
its about two times smaller the the one before ,
and it has a led to tell you if there's power init or not , i'll explain that after ,
despite its size its no weakling it has the same amount of power like the last one ,
so are you ready I'am lets build this thing .

Step 1: What We Need

ok time to get your tool box ready and your parts handy ,
here's what you'll need ,
micro solar cell , I got mine from ebay type in mini solar car and you'll see that cheap looking solar toy for about $2 dollars , that's were I got mine off of ,
a 4.5 volt micro / mini rechargeable battery , you can find this also on ebay , you can type in mini or micro to find it , mine didn't cost

me anything since I had an extra part left from a mini hamburger speaker this was from ebay I paid about $ 3 dollars for it but then it broke on me , hey I didn't break it the dog did ,

next you'll need a very small case , I didn't have one on hand so I had to make one out of plastic I had laying around ,

One led any color you want , I used a blue 3mm , once again from ebay , there pretty cheap a $2 for a 100 ,

one female usb , got mine from my parts box , but you can get one from ebay for like a dollar or cheaper ,

a push button switch , there a dime a dozen , no really there like a dime , ebay 100 for like a dollar ,

and a bridge rectifier diode ,

something to make it look good like paint or aluminum tape , I used the aluminum tape since I had it handy ,

piece of clear plastic , I used a piece of my old gameboy screen ,
and of course some small wire ,

tools you need ,
soldering gun ,
glue gun ,
wire stripper or if you like me you can just use scissors

Step 2: Getting Started

ok now use the schematic as shown in the picture to tell you were it all connects ,
if you want to use a usb pinout to tell were your positive and is ground on a usb you can find it here http://www.usbpinout.net/ ,

now connect the black end of diode to the positive on the solar cell and the connect the grey end of the diode to the positive on the battery , then connect the solar cell ground to the battery ,
next connect the positive from the usb to the positive on the battery and the other to ground ,

note this is not shown in the schematic / picture ,
next your led and switch connect the led's positive lead to one lead on the switch ,
then connect the other lead on the switch to positive on the battery ,
then ground the other lead on your led to the battery ,
now solder all the connections ,
use some glue from your glue gun or electric tape to cover and secure the connections , I used the glue gun it was easier and made it smaller , tape I find it to bulky ,
next fit it to the case , your going to have to make a small it for the led and the switch ,
and you need a hole for your usb ,
and a hole on the top of your case for the top of your solar cell ,
once done we can go to the next step

Step 3: Glue and Cover

ok now put everything in its place and use the glue gun to do so ,
next cut out and a piece of clear plastic to fit over top of your solar cell and glue around it ,
be sure not to get any glue on the top of your solar cell , like shown in the picture ,
if you made a case like I did you need to carefully cut off a the sharp and extra pieces of plastic ,
now its time to make it look good ,
you can paint it what ever color you want making sure you cover the led and solar cell before you do ,
or do what I did take some aluminum tape and cover the case with it , once again do not cover the solar cell or led or the switch ,
ok done great moving on to the last step

Step 4: Testing Testing 123

ok put the little guy out in the sun to charge for a bit ,
now after a bit of charging push the switch and see it glow you should see the led light up ,
so now its time to explain the usefulness of the led like I said I would ,
the led is the easiest why of telling if there is power or not ,
instead of plugging it into a tester or your cellphone every time ,

you can also charge it by using a usb charger as well ,

its good for all usb devices like a mp3 players or a cellphone etc ,
if you what to know how the charging process works take a look at last step of my other micro power 2 go here https://www.instructables.com/id/Micro-pocket-power-2-go-its-solar-to/

next the specs ,
charge time , it will take 4-8 hours by solar ,

about 2 to 5 hours by dc charger ,
and about 2 to 4 hours by larger solar panel , like the one I showed you in the last project

so there you have it your own micro power 2 go 2.0 ,

thank you for viewing and I hope you enjoyed my inscrutable ,

p.s look at the pictures to see the size difference compared to the old version ,
