About: 3D printing and designing RaspberryPI projects for a few years now

Desktop Phone Notification Assistant Featuring (R.O.B.) Robotic Operating Buddy

Step 1: Flashing RaspberriPi Hard Disk / Install Required Software (Using Ubuntu Linux)

Create your new hard disk for DashboardPI

Insert the microSD to your computer via USB adapter and create the disk image using the dd command

Locate your inserted microSD card via the df -h command, unmount it and create the disk image with the disk copy dd command

$ df -h /dev/sdb1 7.4G 32K 7.4G 1% /media/XXX/1234-5678

$ umount /dev/sdb1

Caution: be sure the command is completely accurate, you can damage other disks with this command

if=location of RASPBIAN JESSIE LITE image file of=location of your microSD card

$ sudo dd bs=4M if=/path/to/raspbian-jessie-lite.img of=/dev/sdb (note: in this case, it's /dev/sdb, /dev/sdb1 was an existing factory partition on the microSD)

Setting up your RaspberriPi

Insert your new microSD card to the raspberrypi and power it on with a monitor connected to the HDMI port


user: pi
pass: raspberry

Change your account password for security

sudo passwd pi

Enable RaspberriPi Advanced Options

sudo raspi-config


1 Expand File System

9 Advanced Options

A2 Hostname change it to "RobbieAssistant"

A4 SSH Enable SSH Server

A7 I2C Enable i2c interface

Enable the English/US Keyboard

sudo nano /etc/default/keyboard

Change the following line: XKBLAYOUT="us"

Reboot PI for Keyboard layout changes / file system resizing to take effect

$ sudo shutdown -r now

Auto-Connect to your WiFi

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Add the following lines to have your raspberrypi automatically connect to your home WiFi (if your wireless network is named "linksys" for example, in the following example)

network={ ssid="linksys" psk="WIRELESS PASSWORD HERE" } Reboot PI to connect to WiFi network

$ sudo shutdown -r now

Now that your PI is finally on the local network, you can login remotely to it via SSH. But first you need to get the IP address it currently has.

$ ifconfig Look for "inet addr: 192.168.XXX.XXX" in the following command's output for your PI's IP Address

Go to another machine and login to your raspberrypi via ssh

$ ssh pi@192.168.XXX.XXX

Start Installing required packages

$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get install build-essential tk-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libncurses5-dev libncursesw5-dev libreadline6-dev python3-pip python3-requests python3-setuptools python3-urllib python3-urllib3 python3-requests vim git python-smbus i2c-tools python-imaging python-smbus build-essential python-dev rpi.gpio python3 python3-pip vim git python-smbus i2c-tools python-imaging python-smbus build-essential python-dev rpi.gpio python3 python3-pip libi2c-dev vim git python-smbus i2c-tools python-imaging python-smbus build-essential python-dev rpi.gpio python3 python3-pip python-gpiozero python-psutil xz-utils

$ sudo pip install requests

Update local timezone settings

$ sudo dpkg-reconfigure tzdata

select your timezone using the interface

Setup the simple directory l command [optional]

vi ~/.bashrc

add the following line:

alias l='ls -lh'

source ~/.bashrc

Fix VIM default syntax highlighting [optional]

sudo vi /etc/vim/vimrc

uncomment the following line:

syntax on

make the logs folder for the application to run
mkdir /home/pi/RobbieAssistant/logs

chmod 777 /home/pi/RobbieAssistant/logs

Configure Application to run correctly in config file

Find the file in the /includes/ folder of the project and copy it to and adjust to your current settings

# API key for local weather information

weatherAPIURL = ''


# optional for running the remote temp/humidity logger

dashboardServer = ''

# search google to get the Latitude/Longitude for your home location

latitude = 41.4552578

longitude = -72.1665444

Step 2: Supplies Needed

RaspberriPi Zero

DHT11 Humidistat

LED Lights (x4) Green / Yellow / Blue / Red

2.6" Digole Display

Step 3: Build and Wire the Device

Prepare the Digole Display for i2C

On the back of the Digole Display, solder the jumper to assign the display to use the i2c protocol

Step 4: ​Using a 3d Printer, Print the Cover, Box and Back Panels

Using the following X STL files in the 3DPrint folder, R.O.B. Robot, LED Harness and Display Mount

I used red tape to make the eyes red with the black visor background

Step 5: Component Wiring

Digole Display




VCC -> 3V

DHT11 Humidistat

VCC -> 5V



BLUE Resistor

VCC -> GPIO 17 (with 270ohm resistor)


YELLOW Resistor

VCC -> GPIO 13 (with 270ohm resistor)


GREEN Resistor

VCC -> GPIO 6 (with 270ohm resistor)


RED Resistor

VCC -> GPIO 12 (with 270ohm resistor)


RED Momentary Pushbutton

VCC -> GPIO 16 (with 270ohm resistor)


BLUE Momentary Pushbutton

VCC -> GPIO 26 (with 270ohm resistor)


Step 6: Connect Components to the Robot

After you've printed the screen holder, connect it to the digole display

Connect the Display to the RPi with enough wiring to glue the RPi to the back of the robot

Print the controller and wire the buttons with enough wiring to make it to the back of the robot

Finish Wiring and assembling the robot with the RPi connected to the back and the DHT11 glued to the bottom

Step 7: Check I2C Configuration

Start up your RaspberryPi and make sure the I2C bus recognizes all your connected 7/14 segment displays. [each display is given a unique address described above by how you solder each display's jumpers in different combinations]

If you have the display with jumper soldered correctly, you should have the following output for the i2cdetect command:

sudo i2cdetect -y 1

0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --

10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

20: -- -- -- -- -- -- -- 27 -- -- -- -- -- -- -- --

30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

70: -- -- -- -- -- -- -- --

Step 8: DHT11 Install

$ cd ~

$ git clone

$ cd Adafruit_Python_DHT/

$ sudo python install

$ sudo python

$ cd examples/

$ vi

Change the following line:

sensor = Adafruit_DHT.DHT11

Comment the line out

pin = 'P8_11'

Uncomment the line and change the pin number to 16

pin = 25

Run the test


You should see a metric reading of Temp and Humidity displayed on the command line.

Step 9: Clone Repository

$ cd ~
$ git clone

Step 10: Add Pushbullet API (using Python 3.5)

Using the pushbullet app for your phone, signup to recieve an API key to have a simple python script be able to capture and push data hub notifications and indicator flags

Install Python 3.5 for asyncio functionality

$ sudo apt-get update sudo apt-get install build-essential tk-dev sudo apt-get install libncurses5-dev libncursesw5-dev libreadline6-dev sudo apt-get install libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev sudo apt-get install libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev If one of the packages cannot be found, try a newer version number (e.g. libdb5.4-dev instead of libdb5.3-dev).

$ wget tar zxvf Python-3.5.2.tgz cd Python-3.5.2 ./configure --prefix=/usr/local/opt/python-3.5.2 make sudo make install sudo ln -s /usr/local/opt/python-3.5.2/bin/pydoc3.5 /usr/bin/pydoc3.5 sudo ln -s /usr/local/opt/python-3.5.2/bin/python3.5 /usr/bin/python3.5 sudo ln -s /usr/local/opt/python-3.5.2/bin/python3.5m /usr/bin/python3.5m sudo ln -s /usr/local/opt/python-3.5.2/bin/pyvenv-3.5 /usr/bin/pyvenv-3.5 sudo ln -s /usr/local/opt/python-3.5.2/bin/pip3.5 /usr/bin/pip3.5 cd ~ echo 'alias python35="/usr/local/opt/python-3.5.2/bin/python3.5"' >> .bashrc echo 'alias idle35="/usr/local/opt/python-3.5.2/bin/python3.5"' >> .bashrc Install the python3 dependancies

$ sudo apt-get install python3-setuptools sudo apt-get install python3-pip sudo pip3 install asyncpushbullet sudo pip3 install requests Optional way Download the python repository directly to obtain the python dependancies without the use of pip installing it

git clone
cd asyncpushbullet && sudo /usr/local/opt/python-3.5.2/bin/python3.5 install

Visit the pushbullet settings page in your account to generate an API key to use

Configure your script to have the correct API and dashboard central host

# your API Key from
API_KEY = "o.XXXYYYZZZ111222333444555666"

# dashboard central server host
dashboardServer = ''

Step 11: ​Add the Script to Start at Dashboard Boot and Restart Your Dashboard Pi

$ crontab -e

@reboot nohup /usr/local/opt/python-3.5.2/bin/python3.5 /home/pi/PushBullet/ >/dev/null 2>&1

@reboot nohup /usr/local/opt/python-3.5.3/bin/python3.5 /home/pi/RobbieAssistant/PushBullet/ > /dev/null 2>&1

@reboot nohup python /home/pi/RobbieAssistant/ > /dev/null 2>&1

@reboot nohup python /home/pi/RobbieAssistant/ > /dev/null 2>&1

@reboot nohup python /home/pi/RobbieAssistant/ > /dev/null 2>&1

Step 12: OPTIONAL: Creating Your Own Nintendo Images to Render on the Display

Upload your own 128x128 file to the following URL:

Choose your image file to upload, add what size you want it to be on the screen (Width/Height)

Select "256 Color for Color OLED/LCD(1 byte/pixel)" in the "Used for" dropdown

Obtain the hex output.

Add the hex output to a display/build/ header (.h) file, use the other ones as guides for syntax.

Include the new file in the digole.c file #include "myimage.h

Include a new command line hook to your image file in the. Note: the command below is saying draw your image at position 10 pixels over 10 pixels down. You can change it to different X,Y coordinates, you can also change the values 128,128 to whatever size your new image actually is.

} else if (strcmp(digoleCommand, "myimage") == 0) { drawBitmap256(10, 10, 128, 128, &myimageVariableHere,0); // myimageVariableHere is defined in your (.h) file }

Now rebuild (ignore the errors) below to have your new image render with the following command.

$ ./digole myimage

Re-Building [Included] Digole Display Driver for your optional changes

$ cd display/build

$ gcc digole.c

$ mv a.out ../../digole

$ chmod +x ../../digole

Step 13: Finished!

You're finished!
