Thread: WiFi emitting strength

-

hello,

there way limit wifi card emitting strength? notebok battery seems discharged in short time (much shorter vista).

ubuntu 9.04

thanks!

hi there,

not sure reducing strength of card have difference in battery life. maybe small difference @ best. anyway, there command reduce tx power of card work cards (notoriously buggy).
txpower cards supporting multiple transmit powers, sets transmit power in dbm. if w power in watt, power in dbm p = 30 + 10.log(w). if value postfixed mw, automatically converted dbm.
in addition, on , off enable , disable radio, , auto , fixed enable , disable power control (if features available).
examples :
iwconfig eth0 txpower 15
iwconfig eth0 txpower 30mw
iwconfig eth0 txpower auto
iwconfig eth0 txpower off
http://linux.die.net/man/8/iwconfiganyway, hope helps

luck,

pat.

LED Strip Code

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
