<div>Hi Bernie and all</div>
<div><br>
</div>
<div>That looks an interesting project - I wonder how easy it will
be to implement.</div>
<div><br>
</div>
<div>I have a number of things to share at the next meeting and,
in view of the mention of SystemRescue at the last meeting, I
will bring SystemRescue to the meeting.</div>
<div><br>
</div>
<div>So, if you have a laptop you want examining - as long as it
has power and a working BIOS, even if everything else is dead,
SystemRescue will work - bring it along to BCB on the 11th.</div>

<p>Hi guys,</p>
<div> I've found that Raspberry Pi 5 has a ‘low power’ feature
plus an in-built Real Time Clock, which has a ‘wake up’
capability. 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>
<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>
<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>
<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>
<p>Cheers</p>
