Intro: Backup Energy Saver All in One Kit Powered From a Folding Mobile Solar Panel
First of all i would like to tell you that this is an "OFFGRID CONEST" instructable so please vote if you like the project!
The idea came when i was camping at Lefkada a greek Island (maybe the best beaches in the Europe)
Step 1: Making of the Panel
This is a mobile solar panel.
You can get it with you everywhere.
We made it for camping.
The panel consist of 36 cells (0.45 V , 1.8 watt).
You can watch the full pictorial of the construction here:
Step 2: Making of the Energy Box
-First we have to drive the external power to our batteries...
We do so with a phocus solar charger...
-The batteries are in paraller..
-The circuits for the 5 volt are switching regulators with the lm2576-5.
-The audio amplifier is stereo 2 x 5 watt..
-The speakers are 3 watt 8 ohm..
-The led array consist of 26 red and 24 blue high brightness straw hat leds...
There are 2 scales only the reds or both of them with a switch
They are in paraller with a resistor every 4 leds at 5 volt
-The internal light is a led strip controlled by a terminal switch
-I put a rocker main switch without including the audio amplifier.
-The audio amplifier on off switch is infront of the box with a led indicator...
-Above the box there is the audio in jack for the mp3 player device...
-There is a mini usb outlet next to the audio jack
Red= 12 volt
Brown= input +
Blue= Input -
