[Script] Lighthouse led script - Galaxy S 4 Developer Discussion [Developers-Only]

Since this section is almost becoming a true fossil, buried somewhere in the Sahara dessert, I decide to share just another shell script I made which is for Android.
I call it the "lighthouse" script
Flashbang eye hurt script
, because basically what it does is looping the brightness value of your camera LED, up and down continuously. and it looks kinda like the effect that you get from a lighthouse.
It pulses the led on and off on chosen speed (defined by intervalValue and pauseValue).
IT can be used for example for using it as a way to signal people in an emergency or so
it is probably the best to use it to annoy your friends with it or check out the awesome effect of Tapetum lucidum, make sure to keep a fair distance
Be warned, it may really hurt your eyes and causes temporary blind spots in your vision very rapidly (on long term this will damage your eyes without question)
I am not responsible for any punches or bite marks that you received, nor the eye hurt you caused with this script
Instructions:
1. Copy script to PC and adjust values if needed
2. Push script to phone in an ext4 partition, for example "adb push lighthouse /system/bin/"
3. Set chmod 755 "adb shell chmod 755 /system/bin/lighthouse"
4. Open terminal emulator and type "lighthouse" to run the script
4. Open terminal emulator and type "lighthouse", don't press enter yet
5. Find a suitable target, human or animal with Tapetum lucidum eyes for example. Use script at night for full performance
6. Now run the script and profit (be sure to dodge the counter attack caused by target)
Script
Code:
#!/system/bin/sh
# Lighthouse script
# by broodplank
export max=`cat /sys/class/leds/torch-sec1/max_brightness`;
export intervalValue="0.03"
export pauseValue="0.5"
while [ 1 ]
trap '{ echo "Interrupted, resetting led"; echo 0 > /sys/class/leds/torch-sec1/brightness ; exit 1; }' INT
do
for i in `seq 0 $max`;
do
echo $i > /sys/class/leds/torch-sec1/brightness
sleep $intervalValue
done
sleep $pauseValue
for o in `seq $max -1 0`;
do
echo $o > /sys/class/leds/torch-sec1/brightness
sleep $intervalValue
done
sleep $pauseValue
done
Oh and believe me, you will regret you tested it on your self if you are in a dark room. true story
Use this script responsibly (if possible) :silly:
not sure if troll or real.. it is a script for developers, just has a nasty outcome
