This is the best tool I found. Much faster and much easier to use on Mac. I’ve tried iMovie and it’s ok but it’s not as fast (too many steps and processes). Here is a one-liner that works for me all the time:

ffmpeg -r 4 -pattern_type glob -i “*.JPG” -s 1280×720 -pix_fmt yuv420p timelapse.mp4

Solar: still try to use the deep-cycle battery bought from Walmart on Dec/2012, probably not holding charge too good. Bought a 100W panel from Amazon (Renogy) and a Xantrex 2000W sin-wave inverter. Use biz to finance this project as a solar backup server. Will likely buy 2 Trojan T105 6V batteries to replace the generic deep cycle. Update: ended up using 2x Costco GC2 6-volt battery since Feb 2015. Pretty much dead by Feb 2019, likely because discharged too low a few times (summer was fine, problem is cloudy days during winter, inverter shut down, then tried direct USB, which also drain batteries. @todo replace w/ 4x Costco GC2 6volt to get about 400Ah.

Power power usage of some USB devices:

– Blink Module: 0.1amp (0.46 watt @5V)
– Cell phone charging (Moto G4): around 1 – 1.5amp
– Yi Camera: 0.25amp
– Amazon Echo dot:
– Google mini: 0.25amp
– Wifi hotspot Dlink DWR330: 0.25amp

4x 6-volt battery config:

– Sizing panel + battery: charging rate 10% (rule of thumb 5% to 13%)
225Ah x 2 x 12V x 10% x 1.2 = 648W
– Usage: 1 hotspot, 2 cameras, 1 blink module

– Jan 6, 2019 update: battery too low, controller shut off, will need to recharge battery manually w/ generator. Wonder if because hooking up to the inverter (ghost load) or just becoz cloudy and rain w/o sunshine.

Ever wonder with many in_array() checks, you can speed it up depending on your scenario. In my case, 99% it’s empty so it’s better with an empty() check

<?php
$vResult = array();
$vAry = array();
$vLimit = 10000000;

$vStart = microtime(true);
for ($i=1;$i<$vLimit; $i++) {
if (in_array(123,$vAry)) {
}
} // rof
$vResult[] = “NoEmptyCheck= “.(microtime(true)-$vStart);

$vStart = microtime(true);
for ($i=1;$i<$vLimit; $i++) {
if (!empty($vAry) && in_array(123,$vAry)) {
}
} // rof
$vResult[] = “WithEmptyCheck= “.(microtime(true)-$vStart);

echo implode(“\n”,$vResult).”\n”;

/* Result
