Join Brian Pichman as he uncovers the world of microcomputing; which are low cost, small computers (ranging from the size of a credit card to a stack of credit cards). Brian will cover Raspberry Pi's and how they can be used in your library; from attendance counters, event displays, library programming and more.

Raspberry Pi - Unlocking New Ideas for Your Library
- 1. Raspberry Pi – Unlocking New Ideas forYour Library Brian Pichman | Evolve Project
- 2. This is a Raspberry Pie
- 3. This is what’s in Raspberry Pie
- 4. This is a Raspberry Pi
- 5. This is what’s in Raspberry Pi USB Ports (Mouse, Keyboard, External Drive) HDMI Port for Display Ethernet Port Bluetooth Wireless LAN SD Card Slot (which would be similar to your “hard drive”) GPIO Port (the PINs) General-purpose input/output Power by USB Port
- 6. What is it? The Raspberry Pi is a credit-card-sized computer and it’s incredibly affordable. It is a SoC (system on a chip – a single low voltage chip) Does things that a common Desktop PC does, like spreadsheets, word processing, browsing the internet, and playing games Used by tinkerers, makers, and electronics enthusiasts for projects that require more than a basic microcontroller (such asArduino devices).
- 7. History The Raspberry Pi Foundation is a charity founded in 2009 by Eben Upton to promote the study of basic computer science in schools. Originally designed to run Python (a programming language and framework) (that’s where ”Pi” comes from). Was to help spur the use of more CS students and learning the tools of the 21st Century Kids today didn’t experience the struggles of early computing; when there was some level of coding and scripting required to actually run the OS. By understanding how computers work, you can solve more problems using computers with a basic foundation. Over 11 Million Raspberry Pi’s has been sold since November 2016!
- 11. What can the pins do? Expand your programming ability Light up LEDs Interact with Buttons Add extra devices (motors, gears, sounds, etc)
- 12. Camera Module
- 13. WhatCan the Camera Do? Time-LapseVideos Act as aWeb Camera MiniVideo Camera Still Photography Home Security Monitoring of Nature
- 14. Sense HAT The Sense HAT has an 8×8 RGB LED matrix, a five-button joystick and includes the following sensors: Gyroscope Accelerometer Magnetometer Temperature Barometric pressure Humidity These are aboard the International Space Station until 2022
- 15. 7” Touchscreen Monitor Use your Pi like a tablet! Work as an imbedded project (like a smart entertainment system remote) Touchscreen for 10 finger touch. Only two connections to the Pi are required; power from the Pi’s GPIO port and a ribbon cable that connects to the DSI port present on all Raspberry Pi’s
- 16. Mini Display HAT The 4DPI-24-HAT is a 2.4-inch 320 x 240 Primary Display HAT which plugs directly on top of a Raspberry Pi and displays the primary output which is normally sent to screen. It is also touch sensastive
- 18. Choosing an OS
- 19. New Out Of Box Software (NOOBS)
- 20. The default user is pi, and the password is raspberry. You can add users and change each user's password.
- 27. Download the OS ofChoice to theSDCard Go here: raspberrypi.org/downloads Format SD card as FAT (if 8GB to 32GB) If Over 64GB format as FAT32 (they are typically in an exFAT Format) If Using NOOBS -> copy the zip contents to the Drive If Using any other OS, you will want to install the image to the drive. Download Etcher https://etcher.io/ Follow Prompts in selecting the Image and then the SD Card Finally insert card into Pi In Raspberry Pi 1B+, 2B, 3B is microSDHC card slot. This slot is compatible with maximum 32GB size. However some 64GB+
- 28. First Boot (may take a few minutes)
- 29. Terminal Common in Linux based OS sudo apt-get update = check for system updates sudo apt-get upgrade = download and install updates
- 30. Applications
- 31. What you are used to Web Browser: Epiphany Like Firefox Office Applications: Libreoffice Like Microsoft Media Player:VLC Would be similar to Quicktime / Media Player sudo apt-get install vlc
- 32. Cool Applications within Raspbian Sonic-Pi Sonic Pi is an open-source programming environment, designed for creating new sounds with code in a live coding environment; it was developed by Dr Sam Aaron at the University of Cambridge. He uses the software to perform live with his band. This resource will help get you started with the basics of Sonic Pi so that you can code your own music.
- 33. Cool Applications within Raspbian Scratch Scratch is a visual programming tool which allows the user to create animations and games with a drag-and-drop interface. It allows you to create your own computer games, interactive stories, and animations using some programming techniques without actually having to write code
- 34. Cool Applications within Raspbian Minecraft Minecraft is a popular sandbox open world building game. A free version of Minecraft is available for the Raspberry Pi; it also comes with a programming interface.This means you can write commands and scripts in Python code to build things in the game automatically. It's a great way to learn Python!
- 35. Cool Applications within Raspbian PythonGames If you can figure out how the game works, try to hack it to make it better, make it harder (or easier) to win, or add some features to the game!
- 36. Cool Applications within Raspbian Mathematica Mathematica is a computational programming tool used in science, maths, computing and engineering first released in 1988. It is proprietary software that you can use for free on the Raspberry Pi and has been bundled with Raspbian and NOOBS since late 2013.
- 38. What can you do with Pi
- 39. The Basics: You can control the boxes remotely – usingVNC or tools like Weaved or Dataplicity Your box can serve as a web server or a FTP Site Media Centers, Smart Controllers, the list goes on.And that’s just out of the box. Librarians have used these to build Desktop PC’s for computer labs at low costs.
- 41. OPACs Monitor ($100) Raspberry Pi ($35) Some cabling, wiring, and powering on ($10) Mouse and Keyboard ($25) Compared to 300-600 for a desktop. Set up the LinuxOS to be in Kiosk Mode Which will load a browser window at boot. Set it to your Card Catalog You can configure time out settings, browser refreshers, etc. to keep the browser window clean and clear after inactivity.
