Hey guys,
I'm learning electronics and have begun my adventures by starting with a GREAT project I suggest EVERYONE tries!
What I'm doing:
I will be describing my way through the process of making a Solar Powered adjustable output power supply! I unfortunately don't know enough to have this as a complete instructable, I am asking YOU guys for help! Here is what I have so far [Basically the first few steps, and the last few, the middle ... and most important... are missing]:
Step 1.
You will need the following:
1. Solar panel, 12+ volts.
2. A 12volt DEEP CYCLE Battery
3. A charge controller
4. A power [12v-110/120v] inverter
5. As many DIFFERENT cigarette lighter adapters you can find
6. A switch having as many settings as # of adapters you have.
7. Various USB/Mini USB/Wall plug outlets.
8. Shottky Diodes ( 4-10 will be more than enough)
9. Solder, wire, etc...

Whats going on in this instructable is that we are going to be taking the sun's energy via a photovoltaic cell, and using it to create a battery storage power. That battery will be used to power your phone charger, your ipod charger, re-charging other batteries, as well as powering electronics (be it smaller ones) like a laptop, a lamp, and maybe even a classic gaming system (sega anyone)?
So to start out, there are many instructable on how to do the first few steps:
You may create your OWN photovoltaic (PV) cell by piecing together many small ones:

OR just buy one (I bought many small ones that I will solder together (however they weren't broken).

One good book which covers this is: "Managing 12 Volts by Harold Barre".
Look up on google: LM7805 pdf, it will do 5 volts from anything from 7V to 35V
lots of others are avaliable, like LM780x. x = 10,9,8,7,6,5,3. Look up LM338 i think its a variable voltage regulator. In general, u need at least 1,2 volts more from the source than the output of the regulator, so depending on the volts on your car battery, LM7812 might not work. a regulator usually can supply 1 Amp, but the 78Txx series can supply 3 amps, and its possible to add more in parallel to increase current.
