Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

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.

Are you sure you won't fry the unit . Most panels go well over there rated voltage at full sun and light loads. If it uses a switching reg and suitably rated capacitors and other input componentry you may be lucky but surface mount caps dont like too much extra voltage.

The PSP is powered via a 5 Volt regulator.
I used a car lighter adapter that was rated up to 30 Volts,
so the unit is safer than it would be if it were plugged
into the mains ;)

My post does suggest otherwise...
good pick up.
The PSP would almost always see 5 Volts anyway.
