 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. http://au.youtube.com/watch?v=yioC2p-rVrM 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. If not actually, then potentially. |

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. If not actually, then potentially. |
