Powering a 10V-36V amp with the GPIO - Raspberry Pi Forums

-

hey all, new flesh on site , i've got question.

i'm putting htpc raspberry pi running xbmc, 1 tb hard drive, , old amp (10v-36v dc) friend. i've got 5v micro-usb power supply element14 power thing, , want wire of innards have 1 power cord worry about.

possible power amp off pi using gpio pins, without burning out board? can program thing activate appropriate pins when turns on, i'm none familiar electrical engineering, , google talks lot powering raspberry pi through gpio, not other way around.

information have appreciated.

i'm afraid not. pi supply few 100 ma @ 5v on gpios. i'd expect amp need lot more power (regardless of voltage disparity).

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
