pip install twilio
works perfectly on a Pi2.   Just bought a new Pi3 with the latest NOOB.  
same version of python (2.7.9), same version of pip (1.5.6).  I keep getting the error:

TypeError: __str__ returned non-string (type Error)

Googling around, I checked and verified that
- no network issue, Chromium connects to https://pypi.python.org/simple/twilio/
- my date/time on the computer is correct
- some talk about --trusted-host=http://pypi.python.org/simple/ but that parameter is not valid on pip
- some talk about creating an /etc/pip.conf file and adding trusted-host=pypi.python.org but that makes no difference (assuming pip every reads that file...)

My guess is that it has something to do with the SSL certificates... but I have no idea how to solve it.  
sudo apt-get install libssl-dev did not help

Thoughts?

My son has set up a Raspberry Pi in the home to display images. He enabled FTP and told me to connect via WinSCP. I have done this, and I see all the folders on the Raspberry Pi. However, I cannot upload images or do anymodifications on the raspberry pi due to a permissions problem.

Any ideas what could be the cause of this?

I am logging in with his username and password, which has full rights to the Pi.

Thank you.

How do I embed VideoLan VLC player in a HTML webpage on Raspbian on RPi3?

Hi everyone,

So I've spent the past week reading and trying to understand the python language and more importantly the CherryPy web framework.
To be honest Im getting no-where quickly...

What I'm trying to do is simply build a frontend to a Raspberry Pi project I've been developing.
The CherryPy web framework seems perfect for this as it is small and contains its own web server that would suite my needs perfectly.

An admin user attaches to the Raspberry PI AP and is immediately directed to a webpage (This I have solved quite easily).
The webpage is presented by the CherryPy web server.

I have an index.html which it returned from my CherryPy script.

import os, os.path, sys
import cherrypy

# Configuration file to access server over network and define ports
cherrypy.config.update("server.conf")

class menu(object):
    @cherrypy.expose
    def index(self):
        return open('index.html')

(Fairly simply until now I know)

What I would like to do is have buttons on my index.html that can be pressed and return os.system('mkdir boom')  (obviously my system commands will be a little more than this.. They will start and stop services.

The buttons will eventually be toggle switches, so going to the page will need to return the current status of the running process. Red if the process is not running and Green if it is running. I think I need to be interacting with jquery on my index.html page to achieve this...

This whole area is new to me and …

Hello,

Recently I used the Retropie emulation software for Raspberry Pi. It is a really cool software and is very handy and attractive. So, I was wondering whether I could replicate these softwares on sd cards, install them on pis and start selling them for some small scale business. I would like to know, if doing such a thing would be legal. Actually, there are quite few ideas about using pis as portable media centers, portable game consoles, a simple portable desktops or just a cheap monitoring cameras. It can be customized to the very end for users and can be an attention grabber in certain circles. But what would be my legal position and what, if any, licensing would it require to start such a business?

Thanks in advance.

I need a code in Embedded C for making call andi sending SMS by using Raspberry pi 3 and GSM SIM 900. Please help me. I am new to Raspberry pi

I have an analog door opener system in my building, this is the phone which opens the door: http://pasteboard.co/4JgctXi4x.jpg
I have a raspberri pi 3 model b, and a Pcf8591 ADC/DAC converter: http://articulo.mercadolibre.com.ar/MLA-641278286-modulo-pcf8591-conversor-4-ad-da-i2c-arduino-raspberry-_JM

What I want to do, is to connect the wires that goes to the analog door opener phone system into Raspberri PI, so I can hear/speak from a sip softphone installed in the raspberry pi.

Is this possible? I measured the voltage in the mic phone/speaker, it's shown in the picture. Not sure how to proceed with this.

Anyone? Thank you!!

Hello,

I have been trying to set up I2C communication between my Raspberry Pi and two arduino pro minis using this tutorial:
https://learn.adafruit.com/adafruits-raspberry-pi-lesson-4-gpio-setup/configuring-i2c

I have done all the steps correctly, installed all the required dependencies and modified all the required files, yet "sudo i2cdetect -y 1" does not detect the arduinos. I have two PCF8591 AD/DA converter modules, and when I connect them to the RPi using the SCL and SDA ports, they are detected and shown by "sudo i2cdetect -y 1". But the arduinos do not show up. This is How I have connected the RPi and the Arduino Minis:
RPi                -> Arduino
3.3V               -> Vin
GND               -> GND
SDA(GPIO2)  -> SDA(A4)
SCL(GPIO3)   -> SCL(A5)

I would like to know what is going wrong here. Please suggest.

Hi experts.

I have been trying to automate some infrared command through my Raspberry Pi, using the IRDroid-Rpi infrared transceiver (http://www.irdroid.com/2016/10/discover-how-to-turn-raspberry-pi-into-a-infrared-remote-control-using-the-irdroid-rpi/). These commands must be first learned from my Set Top Box infrared remote control using irrecord, but it is a commercial remote.

I have followed the documentation and finally got the IRDroid-Rpi to work. However, it will only work if I learn commands from commercial remote controls like a Samsung TV remote control. My STB remote control is non commercial, and I have not been able to make the IRDroid-Rpi learn and send the commands correctly. Here is my procedure and files:

pi@raspberrypi:~ $ sudo irrecord -f -d /dev/lirc0 lircdtp2.conf

Press RETURN now to start recording.

Dear experts,

I am a novice in raspberry pi. I want to make a door lock which should be unlocked only when it detects presence of myself within a range not for others.

Is it possible? What type of sensors need to be used for that? Any tutorial or advice?

With regards,
Roy

I am designing my first Raspberry Pi app .... It tracks a volley ball game ... I have found a lot of motion tracking ... I need a tutorial teaches me how to map the court ... the court has white lines ... when the ball goes beyond the white line an LED will light up ... how can I get raspberry to map the court ?
