Battery Powered RC car with RPi2 - Raspberry Pi Forums

-

i making remote control car , have battery pack can hold 6 aa batteries. these batteries rechargeable , supply 1.2v. 6 of batteries give me 7.2v. therefore need use 5v voltage regulator power raspberry pi 2 (motors run off of 7.2v in parallel raspberry pi 2's 5v supply). not know how should connect battery pack pi have found several options. simplest option me seems connecting regulated 5v wire 1 of 5v pins , ground wire gnd pin. however, concerned current going in pi because there no fuse protect it. how current going in? keeping in mind raspberry pi 2 take 2000ma wall supply, current in tolerable range power pi (considering of current going motors well)? should consider option power pi? there safety precautions should take?

again main questions are:
1. how current going raspberry pi 2?
2. current supplied adequate project?
3. should power pi using option other gpio pins (microusb port, usb port)?
4. there safety precautions should take?

in advanced. please ask details problem if necessary , feel free leave suggestions.

save lot of headaches , corrupted sd cards unexpected reboots.

use "phone charger" usb battery pack power pi, use 6xaa motors, otherwise asking trouble.

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
