A 'Seconds to wake up' value can be inserted into a file which is read on going low power (Linux ‘shutdown’ but retaining power to the board). After the given seconds, the board powers up again.<br> <br> This suggests a time lapse project. I would like to take a mid-day photo of an apple tree I have, throughout a year, to stitch in a film showing snow on bare tree, spring blossom, leafing up, growing apples, falling leaves. But due to the difficulty of getting power to the garden, I’m thinking of a Solar panel plus battery with raspberry pi with camera, all boxed up and mounted.<br> <br> So the Pi would be in low-power mode apart from a brief mid-day on-time for the photo, plus a possible evening on-time period to give myself a chance to connect and pull down photo’s or do any changes - hopefully this would make the solar/battery combo possible.<br> </div><div> </div><p>I'll be having a go at a script to do timed power ups/downs, but I've not given much thought to anything else such as:</p><div> </div><div> </div><div> </div><ul> <li>Solar panel, battery, power management.</li> <li>I should be able to get wifi to the garden, but may need an external antenna if the boxing is a problem.</li> <li>Which camera/lens, and its protection: glass covering or naked lens.</li> <li>The physical box and mount.</li> <li>Should the pi monitor voltage, (if possible), provide warnings, auto send any data?</li> <li>The RTC can also have a small battery backup in case external power fails, probably needed. <br> </li> </ul><div> </div><div> </div><div> </div><p>I'd be interested in any suggestions, or if anyone has any experience with Pi cameras, solar panels and batteries. Perhaps something to discuss at the next meet?</p><div> </div><div> </div><div> </div><p>Cheers</p><div> </div><div> </div><div> </div><p> Bernie<br> </p><div> </div><div> </div><div> </div><p><br> </p><div> </div><div> </div><div> </div><p><br> </p><div> </div><div> </div><div> </div></blockquote><div> </div><div><br> </div><div> </div><div><span></span></div><div> <br> <fieldset class="moz-mime-attachment-header"></fieldset> </div></blockquote><div> </div><pre></pre></blockquote><div><br></div><div><span></span></div></body></html>
