For under $160 you can construct a Solar Photovoltaic Renewable Electron Encapsulator (SPREE) to harness clean carbon-free solar electricity to power your portable electronic devices.
SPREE is an experiment in alternative energy and solar generated electricity.The impetus for construction was the desire to have my cellular phone and other small electronics run entirely from free* renewable solar energy.

-------
STEP 1
-------
Gather Components for S.P.R.E.E.
The components are very basic, involving a photovoltaic panel, a rechargeable battery, a charge controller, and the sun. You should not spend more that $160, unless money is no object to you. Not the case for me.
5-watt, 12-volt photovoltaic panel, $36, eBay, Solar Cynergy: PV-SC005J17
1/4" mono plug (2), $1, allelectronics.com, SPH
DC solar charge controller, $28, allelectronics.com, SCN-2
12-volt 12-AH rechargeable battery, $40, allelectronics.com, GC-1214
10-feet of 18-gauge wire, $3, allelectronics.com, WRB-18
cigarette lighter "Y" adapter, $4, allelectronics.com, CLP-Y
200-watt power inverter, $17, walmart.com, 001088173
plastic box with split folding lids, $5, target medium bin
wood/hardware for mounting, $4, lowe's, 1x3x4, screws
This leaves about $22 for random parts, upgrades, accessories, shipping fees and taxes.
Necessary tools: Power drill and creativity.

STEP 2
-------
Construct a Box For S.P.R.E.E.
I selected a plastic bin with a split opening lid worth $5 at Target. I picked it because it was cheap, durable, easy to modify, and relatively weather-proof. Drill plenty of holes in it to provide airflow. I also drilled holes to add bungee cords to hold the battery secure. And, I drilled a hole for the mono jack to go into the box, leaving the cigarette socket outside of the box.
Be creative. Hollow out an old TV or CRT monitor and use that as your box.
-------
STEP 3
-------
Wire S.P.R.E.E.
The wiring is very simple and intuitive. Basically, the photovoltaic panel and the battery are connected to the charge controller.
The charge controller has a 12 volt output. This output is in the form of a 1/4 inch mono jack. The first step involves cutting off the cigarette lighter plug from the Y-adapter and soldering the mono plug to the cigarette lighter socket. (Since it was a Y adapter, and there was 2 sockets, I made 2 mono-plug-to cigarette-socket "connectors", one as a backup) Make sure to test your connections.
Connect the photovoltaic panel to the charge controller. Insert the 1/4 inch mono jack into the 12 volt output of the charge controller. Check your connections again.
I drilled a hole in the plastic box top, and then attached 2 wooden boards to the top of the box. I then attached the photovoltaic panel to 1/2 inch square wooden dowels. I then created a hinge using speaker wire and screws, which holds the photovolatic panel secure yet allows tilt from 90 to 180 degrees. Then I drilled another hole and inserted the mono jack and left the 12 volt cigarette lighter outside of the housing, but made a holster for it by using a zip-tie.

STEP 4
-------
Energize S.P.R.E.E.
After all connections have been made ,double check them and test them with a multimeter before connecting to the battery.
Connect the red wire to the positive (+) terminal of the battery, then connect the black wire to the negative (-) terminal of the battery.
Note: The photovoltaic panel will charge the battery even when the charge controller is OFF. The charge controller has to be in the ON position to power 12-volt cigarette lighter socket.

STEP 5
-------
Utilize S.P.R.E.E. then Rejoice in Clean Renewable Energy
Place S.P.R.E.E. in the sunshine to charge the battery.
Adjust the photovoltaic panel at an angle roughly equal to your latitude for optimum electron encapsulation. Check out U.S. Gazetteer to find your latitude and check your angle with a protractor.
At night, bring it inside, and plug your 12 volt electronics into the cigarette lighter socket to charge. OR, get an DC to AC inverter. It will use some of the electricity to convert the energy, but you will be able to charge AC electronics. Although, it would be more efficient to use DC electronics with this small scale system.
Smile and know that you are using only clean carbon free energy when you talk on your cell phone, take photos with your digital camera, or play PSP.
