This is a part of the slide set used at the MakerSpace Noida (India) launch event, Pi Maker Workshop. This slide set is designed to help people get started with the Raspberry Pi and also serves as a collection of innovative projects and some core basic concepts that can aid anybody with their first few steps into the world of DIY electronics or maybe serve as a refresher for the experienced. Feel free to refer and share but please don't alter the watermarks :)

- 2. Mayank Joneja What is a Raspberry Pi ? Raspberry Pi is a low-cost, basic computer that was originally intended to help spur interest in computing among school children by exposing them to the “Bare Bones” of a computer in this age when everything is a closed black box to the user.
- 3. Mayank Joneja The Raspberry Pi is contained on a single circuit board roughly the size of a credit card. It features ports for: Video: HDMI / Composite Video Audio: HDMI/ Analog audio Micro USB port for power supply Ethernet Port SD Card 2 USB 2.0 ports The computer runs entirely on open-source software and gives students the ability to mix and match software according the work they wish to do It is one of the world’s smallest and cheapest computers
- 4. Mayank Joneja Fine, what can I make with it?
- 7. Mayank Joneja Hi, what’s your name? Programming Experience (Any language) Hardware/Electronics knowledge Linux? Networking/Router Configuration? Interests? Photography? Music? Hacking? etc etc
- 8. Mayank Joneja MakerSpace what? To describe them simply, makerspaces are community centers with tools. Makerspaces combine manufacturing equipment, community, and education for the purposes of enabling community members to design, prototype and create manufactured works that wouldn’t be possible to create with the resources available to individuals working alone. These spaces can take the form of loosely-organized individuals sharing space and tools, for-profit companies, non-profit corporations, organizations affiliated with or hosted within schools, universities or libraries, and more. All are united in the purpose of providing access to equipment, community, and education, and all are unique in exactly how they are arranged to fit the purposes of the community they serve.
- 9. Mayank Joneja Makerspaces represent the democratization of design, engineering, fabrication and education. They are a fairly new phenomenon, but are beginning to produce projects with significant national impacts. http://net.educause.edu/ir/library/pdf/eli7095.pdf Notable projects: Pebble Watch (a programmable watch whose team is the recipient of the largest Kickstarter campaign in history) MakerBot (creators of a low-cost 3D printer that’s revolutionizing the entire rapid prototyping industry) Square (a painless payment gateway enabling small businesses to collect money easily worldwide)
- 10. Mayank Joneja RasPi: Origins The Raspberry Pi debuted in February 2012 The group behind its development: The Raspberry Pi Foundation started this project to make computing fun for students while also creating interest in how computers work at a basic level. Eben Upton, Founder and Trustee of Raspberry Pi Unlike using an encased computer from a manufacturer, the RasPi shows the essential guts behind the plastic. Even the software, by virtue of being open source offers and opportunity for the users to explore the underlying code – if they wish The RasPi is believed to be an ideal learning tool, in that it is cheap to make, easy to replace and needs only a keyboard and a TV/Monitor to run. The same strengths also make it an ideal product to jumpstart computing in the developing world.
- 11. Mayank Joneja Early prototypes Veroboard and PCB versions of the prototype
- 13. Mayank Joneja Tech Specs CPU: Broadcom BCM2835 system-on-a-chip (SoC) This SoC includes: 32 bit ARM1176JZFS processor, clocked at 700MHz (can overclock safely up-to 900MHz) Videocore IV GPU 512 MB of RAM in a POP package above the SoP
- 14. Mayank Joneja Power Supply: The Raspberry Pi requires a stable 5V ( 800mA at least) power supply. It can be powered from the GPIO pins as well however the power supply protection is only featured on the Micro USB port. Any Android/Blackberry cell phone charger works well Prefer not to power it from your PC/Laptop USB In order the make the Power Supply portable, one of the easiest and most reliable ways is to power it from a Portable 5V Mobile Phone Charger One can even hack a car charger which converts 12V DC to 5V DC and use it with an 11.1V LiPo or Li-Ion battery It is very easy to damage the Raspberry Pi through a power supply problem or for instance if you power it through the GPIO directly (Kids, always use protection :P) however, for most of such cases, the Raspberry Pi’s “MAGICAL” self healing fuses are good enough to bring your Pi BACK FROM THE DEAD :D
- 16. Mayank Joneja Storage: SD Card (if using micro SD card, you’ll need an adapter) Main purpose that the SD Card serves is to run the Operating System (Linux variants) for the Raspberry Pi Minimum requirements: 2 GB (only OS), Maximum: 32 GB 8 GB suffices for most applications Preferably use Class 10 and above for fast data access The kernel boots from the SD Card It is also possible to use a USB Pen drive to run the OS however that implementation is not so frequently seen as that ends up blocking one of the 2 available ports.
- 17. Mayank Joneja Video HDMI or (digital) DVI via cheap adapter/cable Composite NTSC/PAL via RCA Wide range of resolutions No VGA (analog video) without an add-on, non trivial converter (most reliably- from Adafruit)
- 18. Mayank Joneja Audio Via HDMI or from a 3.5mm stereo jack Output only
- 19. Mayank Joneja Networking 10/100 MBPS via RJ45 on model B Wireless via USB add-on supported
- 20. Mayank Joneja USB Dual USB sockets on RPi model B, single on model A Expandable via regular or powered USB hubs Cannot source enough power to run External Hard Disk drives from the USB power supply or some high demand Wi-Fi dongles and Data Cards Best to use a Powered USB hub when connecting several devices. This allows for the sharing of data on the USB line but draws power from an external 5V 1A (or more) adapter
- 21. Mayank Joneja General Purpose Input Output The Raspberry Pi features a 26Pin header for GPIO access which runs at 3.3 V logic The pins are NOT 5 V or short tolerant Parallel I/O pins UART Linux console support I2C, SPI for peripheral interfacing Around 17 True GPIO pins that are re-programmable for users on the main header Other headers to offer features like JTAG support, CSI camera support, DSI LCD Panel support and additional GPIO
- 23. Mayank Joneja Difference in Model A and B Model A 256 MB RAM One USB port No Ethernet support Model B 512 MB RAM 2 USB ports 1 Ethernet port
- 24. Mayank Joneja Raspberry Pi vs Arduino For those of you who’ve been following or involved in the world of DIY Electronics, the Arduino must be a familiar name. Several times while starting off with projects, its important to understand the differences between both in order to make the most optimal use of resources and time. Let’s have a look at this helpful description: https://www.youtube.com/watch?v=7vhvnaWUZjE

- 26. Mayank Joneja The Raspberry Pi Tools Win32Disk Imager SD CardFormatter ( different formats: ext4/fat32/ntfs) PuTTY VNC Sublime-Text Web browser: (I use Chrome) Samba so that one can simply access files through Windows Explorer WinSCP AdvancedIPScanner Router Config Linux on your Laptop-to view and edit files on the ext4 partition of the SD Card--use Vmware, or just a boot disk if you don’t want to install a dual boot system (Interfaces file)
