2 Axis IP Camera with Raspberry Pi 3

thingiverse

Just to improve my Python skills, I created a two-axis camera using a Raspberry Pi with Motion as the streamer and my own Python script to control two servos, MG 90, via remote or stand-alone. The ground plate is not included, so you'll need to add your own piece of aluminum or wood to make it more stable. I used a PLA webcam from Amazon (https://www.amazon.de/gp/product/B01FDCK6FS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) and an MG 90 servo from Amazon (https://www.amazon.de/gp/product/B07FQMTLD4/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1). You can check out a video of my setup in action here: https://www.file-upload.net/download-13847381/TRIM_20200105_120410.mp4.html. Here's the code I'm using: ```python #!/usr/bin/python3 import RPi.GPIO as GPIO import time import socket import threading servo_kipp = 23 servo_dreh = 18 GPIO.setmode(GPIO.BCM) GPIO.setup(servo_dreh, GPIO.OUT) GPIO.setup(servo_kipp, GPIO.OUT) d = GPIO.PWM(servo_dreh, 50) # GPIO 18 als PWM mit 50Hz k = GPIO.PWM(servo_kipp, 50) # GPIO 18 als PWM mit 50Hz def dreh_by_read(): with open('/home/pi/Servo_1/servo_dreh_n.txt', "r") as fo: first_line = fo.readline() x = float(first_line.strip('HTTP 1.1')[:-14]) d.ChangeDutyCycle(x) time.sleep(0.5) d.ChangeDutyCycle(0) def kipp_by_read(): with open('/home/pi/Servo_1/servo_dreh_n.txt', "r") as fo: first_line = fo.readline() x = float(first_line.strip('HTTP 1.1')[:-14]) k.ChangeDutyCycle(x) time.sleep(0.5) k.ChangeDutyCycle(0) bind_ip = '192.168.178.66' bind_port = 9999 server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server.bind((bind_ip, bind_port)) server.listen(5) print ('Listening on {}:{}'.format(bind_ip, bind_port)) def handle_client_connection(client_socket): request = client_socket.recv(1024) client_socket.send(b'Ack') request = request.decode() clean = request.split('/', 1)[1] foo_clean = clean.split('</body></html>', 1)[0] with open('/home/pi/Servo_1/servo_dreh_n.txt', 'r+') as zoo: zoo.write(foo_clean) if 'DREH' in clean: print(' Doing dreh ') dreh_by_read() elif 'KIPP' in clean: print(' Doing kipp') kipp_by_read() client_socket.close() while True: client_sock, address = server.accept() print ('Accepted connection from {}:{}'.format(address[0], address[1])) client_handler = threading.Thread( target=handle_client_connection, args=(client_sock,) ) client_handler.start() ``` Enjoy!
