Solar Monitor for Sony PSP :)

Hi Guys,
Thought you might like this...
As I use a dedicated 10 Watt solar charger for my PSP,
it made sense to write some functionality to monitor it's own charger.

While camping, I am running this program for other reasons.
Since the PSP unit is constantly running, incorporating these routines
means I get a solar logger for free.

The PSP doesn't know input voltage at it's power connector,
just that it's over the threshold required to power the unit,
so the graph is like a yes or no state.
Monitoring the battery voltage of the PSP is possible though.

I'm a programmer, so if you rate my video, round it off to the nearest extreme
Cheers, Art.

I wasn't exactly sure what I was looking at - I guess the bar across the bottom grows when sunlight is falling on the solar cells?

Nice clock, in any case!

The plain old test bench video gives a clearer idea:

like roderick i wasn't sure what the 1st one was either, but that 2nd one was much clearer. i don't have one of those psps, but i'm guessing that was a general power level indicator or charge indicator.

Yes, it's a graphic log that keeps moving left like an old mechanical graph
where a needle moves on an unwinding roll of paper.
So when the light comes on on the video, the next dot is printed on the top line.
Unfortunately, it's only able to record the two states of either charging or
not charging, but that's ok for a PSP charger.
