To the edge of space and back with Raspberry Pi on a High Altitude Balloon (HAB). These students have had 5 successful launches sending the Raspberry Pi to the edge of Space and Back. They maintain telemetry via 2.39 GHz radios and stream live video back to earth throughout the flight.
In this tutorial we show you how to run the Raspberry Pi graphical user interface remotely. You can have the GUI from your pi show up on your windows based machine. This allows you to easily interact with and control your Pi from a remote location.
I really hate having to double click on icons to make them open. IN this lesson we show you how to configure your Raspberry Pi graphical interface to open icons with a single click.
This lesson shows you how to install a full feature word processor and spreadsheet onto your Raspberry Pi. The product is free and really expands what work you can do on the Pi.
This lesson shows you how to get Chromium running on your raspberry Pi. This is a version of Google Chrome that will run on the Pi.
This tutorial shows how to boot your raspberry pi into the graphical user interface. This interface has the look and feel of Windows, and allows graphical navigation of files and folders.
As much as we love the Raspberry Pi, the fundamental limitation of the device is that it does not have analog inputs. For projects requiring analog inputs, we suggest adding an arduino and setting up a client/server relationship between the Pi and Arduino.
This tutorial shows how to build a dimmable LED using the Raspberry Pi. We bring together much we learned in the earlier lessons, and use GPIO input and output, and use PWM.
This tutorial shows you how to control LED’s using the GPIO pins on the Raspberry Pi using Python. This demonstrates use of the GPIO pins as both inputs and outputs.
This lesson shows you how to do a digital read from the Raspberry Pi GPIO pins. We give some simple example using a circuit with push buttons. We show how to activate the internal pullup resistors.
In this lesson we present a simple step-by-step tutorial on controlling a servo with the Raspberry Pi. The lesson shows how to accurately achieve any desired position.
This lesson shows you how to use PWM output on the GPIO pins on the Raspberry Pi to simulate analog voltage output. We demonstrate this by creating a dimmable LED. LED brightness is controlled by the duty cycle of the PWM wave.
In this tutorial we show how to control the GPIO pins on the Raspberry Pi from a python program. We introduce the concepts by running commands from the python shell, and then show how to blink an LED using a python program. We explore both the BOARD and BCM pin numbering schemes.
This lesson shows you which pins can do what on the Raspberry Pi 2. We discuss the two different numbering protocols . . . bcm and Physical Pins.
In this lesson we show how to run python programs on the raspberry pi. The lesson shows that python comes preinstalled on the py, and we show how to select different versions of Python.
This video describes how to change file and folder permissions on the Raspberry Pi. We describe the use of the CHMOD command in linux. We look at recursive changes as well.
This video introduces you to the concept of file and folder permissions in Linux. We go through some simple examples.
This video shows how to create a new user account on the Raspberry Pi with the same admin privileges as Pi. This will give access to the sudo command and allow system modifications.
It is very easy to end up corrupting your SD card or operating system on the Raspberry Pi, so it is important to be diligent about making backups. In this video we show you a simple way to back up your SD card, and how to load the operating system from a backup if needed.
This lesson shows you how you can add new users to the Raspberry Pi. We also show how to delete users.
