How to prevent servos from breaking

-

hi wise , powerful council of arduinonians.

i working on project utilizes dozens of servos. because need many, use cheap tower pro

http://www.ebay.com/itm/5pcs-x-sg90-micro-9g-servo-for-rc-airplane-car-boat-genuine-/400471432862?pt=radio_control_parts_accessories&hash=item5d3df51e9e

unfortunately keep breaking. seems gears jammed. know causes them jam , how avoid this? if answer paid for, know of servos high quality , cheap (under $10)?

do have enough torque ? nylon gears jam ?
servos metal gears more expensive, , don't know kind of special things them. perhaps can reduce mechanical stress programming slow start of rotation in sketch.

have @ website of www.sparkfun.com , www.adafruit.com
search 'servo'. shops have selection of products.

or do, buy many servo motors , let them run days see 1 okay.

hello everyone, name kedi.. make system connecting raspberry pi 2 , arduino uno arduino adc of 1 dust sensor sharp gp2y1010au0f , 4 gas sensor. want show decision of air quality system in running text @ p10 16x32 led dot matrix display. in raspberry pi 2, connect p10 pins in gpio25, gpio12, gpio16, gpio13 & gpio26. now, i'm finish circuit , don't know must connect p10's vcc & ground (red & black wire). can me? , code in python controlling p10(1r)-v706 dot matrix?.. regards, kedi i can't python code (did mine in basic on risc os) regarding power, panels each require 2.5a, you'll need separate supply them. if attempted power them pi, pi's polyfuse blow immediately. alternatively, use supply capable of giving 10a supply both panels , pi. raspberrypi

hi, thank help. question simple: how convert raspistill data opencv processing. code: select all def capture(settings, width, height): command = "raspistill %s -w %s -h %s -t 200 -e bmp -n -o -" % (settings, width, height) imagedata = stringio.stringio() imagedata.write(subprocess.check_output(command, shell=true)) imagedata.seek(0) im = image.open(imagedata) buffer = im.load() imagedata.close() return im,buffer code: select all image1, buffer1 = capture(camerasettings, testwidth, testheight) cv2.imshow('image',image1) want use different opencv processing techniques, before need know doing wrong. bests svato raspberrypi
