Solar Powered Digital Picture Frame

Here is a neat little gift I made for my wife last Christmas.  It would make a great gift in general though - birthdays, anniversaries, Valentine's Day or other special events!

At the core is a standard off-the-shelf keychain digital picture frame.  It is mounted in a fancy enclosure, in this case a flower that is modeled after a chrysanthemum.  On top of that, a solar cell has been added so that the picture frame will run indefinitely when placed in a sunny window!  Or, you can simply plug it into any USB port and let it run from there.

It can be made using basic tools, including an X-acto knife, soldering iron, wire strippers, and a drill.

Step 1 Materials and Tools

All of the materials should be pretty easy to find, and most can be substituted or completely changed if you want to. I had to buy the two most important pieces, the digital picture frame and the solar panel, but everything else was just lying around.

MATERIALS

1.5" Digital picture frame - DealExtreme.com
5V, 160mA Solar Panel - DealExtreme.com (or equivalent)
Small flower pot
Some pieces of craft foam - available at any craft store
A mini USB cable - online or in stores
A 0.3V Germanium Diode - to protect the solar panel
Some bits of wire
A chunk of wood, between 0.5 and 1" thick
Some hard plastic drinking straws (or equivalent)
White glue

TOOLS

A Soldering Iron
A Glue Gun
A Scroll Saw or Band Saw (optional)
A Drill Press (or a hand drill, in a pinch)
Scissors
An X-Acto knife with a fresh blade
A computer and printer
Wire cutters/strippers

Hi, I'm really having a hard time finding the 0.3V Germanium Diode. A lot of places don't know what this is...

Thanks for any help I can get

That's not really a requirement - any low-voltage diode will do. You could stick in a regular 1N4001 in there and it would work, though you'd need more sunlight before the charger kicks in.

Hi, I would like to if I can stay with the original plan. Where did you the 0.3V Germanium Diode ? I don't know much about electronics. I'm slowly reading and learning about it...

Thanks,
Peter

Doesn't exist anymore, apparently. As I said, any diode with a low forward voltage will be fine. This one is less than 60 cents at Digikey: CDBA120SL-G. It will work great!

 awesome one....really appreciating idea......ahhhhh but these things aren't  available in pakistan.

That'll make things tricky.  But really, you could use any pocket-sized digital picture frame you can find, it doesn't have to be this one.

Lovely!  Good pictures and plenty of detail in there. Thumbs up!
Had you thought of making a USB plug in the base of the pot or concealed under some fake dirt?  That way you could move it away from the computer to a window shelf and ditch the trailing wire - suppose you would need a donor USB cable to take a plug from. 

Very nice idea.

[jeff-o]

That's a great idea!  And yeah, you could cut apart a USB extension cable to do that.  If you like, the USB cable could also be hidden inside the pot (instead of coming up through the surface).

Cool idea, and the flower looks really nice!
