Lab 10A

Blockchain on the Raspberry Pi!

Lab 10A Continued!

Decentralized content sharing on the Pi!

Lab 9

Lab 9A

Generating UML, converting to a PNG, and displaying the diagram using X forwarding on the Raspberry Pi.

Lab 8

Lab 8A

Running TensorFlow and Keras on a Raspberry Pi and forwarding graphical information to a remote display.

Lab 8B

Using MatPlotLib to visualize usage and temperature information about the Pi

Lab 7

Lab 7A: ThingSpeak Requests

Sent from a Raspberry Pi after setting up a ThingSpeak account and acquiring a write API key

ThingSpeak Visualization

Requests tracked on thingspeak.com

Lab 7B

Set up the Google Cloud platform to publish data from a Raspberry Pi to a Google Spreadsheet

Lab 6

Lab 6A

Demonstrating Node.js on a Raspberry Pi. Responses were triggered by refreshing the browser window on the Pi.

Lab 6B

Running Pystache!

Lab 5

Lab 5A

Setting up and demonstrating Docker on the Raspberry Pi

Demonstrating crossbar.io functionality. Left: Subscriber, Middle: Publisher, Right: Router

Lab 5B

Setting up MQTT servers and connecting two nodes with Mosquitto and Eclipse Paho.

Using this server to gather information about the status of connected nodes

Lab 4

Lab 3

Successfully ran a sample server-client setup on a single Raspberry Pi

LED remote control from a host. The LED proceeded to blink on and off.

Lab 3E

Profiling the PyPy tool against Python and Python3 on the Raspberry Pi

Lab 3F

Using html2text with doxygen

Lab 2

Lab 2A: Serial Loopback Test

Minicom

The minicom utility was used to transmit and receive serial information. The duplicated letters show that the utility was both sending and receiving data on the serial line, as would be expected from this setup.

Raspberry Pi Serial Connection

Pins ___ and ___ were connected to create a serial loopback.

Notes: In order to allow proper communication over the UART port, it needed to be enabled with the raspi-config script

Lab 2B: Serial Peripheral Interface

SPI Dev Test

The provided spidev_test utility was used to test the established SPI connection.

Raspberry Pi SPI Connection

Pins __ and __ were connected to create a SPI loopback for test purposes.

Again, this connection needed to be enabled, but this time by editing the /boot/config.txt configuration file. Details about this procedure can be found here: https://www.raspberrypi.org/documentation/hardware/raspberrypi/spi/README.md

Lab 2C/D: Breadboard and Light-Emitting Diode

Directly Controlling GPIO

The Raspberry Pi allows a very straight-forward interface for controlling GPIO from the command line, as seen above.

LED Off

LED status before setting value = 1

LED On

LED Status after setting value = 1

Note: All other components of lab 2 could not be completed due to a lack of appropriate hardware components.
