Raspberry Pi, Arduino and the Maker Movement
- 1. Raspberry Pi, Arduino and the Maker Movement Dr. Simon Monk
- 2. Simon Monk • Full-time Author - Open Source Hardware and Electronics
- 3. Audience • Who has used an Arduino? • Who has used a Raspberry Pi? • Who teaches Electronics?
- 4. Objectives • Understanding the Maker Movement • Post Expert design and manufacture • Maker Examples • Platforms for Physical Computing • Open Source Hardware
- 6. ‘Post-Expert’ Making Why is this possible? With the advent of the Internet, expert knowledge is now freely available to all. Open Source Hardware - designs are not secret, learn by example and modify. ‘Expert’ amateurs create tools for ‘less expert’ Makers (Arduino etc.) Services - PCB fabrication, 3D printing, laser cutting Very low cost of entry Hackspaces and FabLabs provide shared tools and

- 9. Bubblino
- 10. Etch-a-sketch
- 11. Global Show and Tell • Instructables.com • Hacknmod.com • Youtube • Blogs • Books
- 12. Hen-House Door
- 13. Platforms for Physical Computing • Arduino • Raspberry Pi • BeagleBone Black • Spark Core (IoT) • Microcontroller chip on homemade PCB
- 14. What is an Arduino? USB Power Digital Inputs / Outputs Analog Inputs
- 15. Arduino Software
- 16. Types of Arduino • Uno (standard) • Bigger ones (Due, Mega) • Smaller Ones (Nano, Mini) • Drone Piloting (ArduPilot) • Wearable (lilypad, flora) • Built-in Ethernet / WiFi (IoT)
- 17. Shields • Ethernet / WiFi • Motor Driver • Relay • LCD Display • USB Host • Sensors • etc.
- 19. Demonstration • LED Cube
- 20. What is a Raspberry Pi? • USD 40 • Debian Linux • HDMI • USB
- 21. Hardware • 512 MB RAM • 700 MHz • GPIO
- 22. Computer or Physical Computing Platform? • Both • For many users, its just a very cheap Linux Computer • But, also capable of interfacing with sensors and actuators
- 23. Demonstration • Software Radio • Imperial College
- 24. Programming Pi • Python • Tkinter - GUIs • PyGame - Games • Scratch - Visual Programming • C, Java, Clozure CL, Squeek, LAMP (Linux, Apache, MySQL and PHP)!
- 25. Pi Expansion • GPIO Connector • I2C • Serial • General Purpose IO Pins
- 26. Pi is not Arduino • Linux - Not a Real-time OS • Timing unpredictable • Not good for • Servos, PWM • Pulse measurement • No Analog Inputs • Low current (delicate) GPIO pins • 500mA vs 50mA
- 27. BeagleBone • BeagleBone Black • ‘American Pi’ • More GPIO pins than Pi • Analog inputs • Javascript (Node.js)
- 28. BeagleBone • Web Programming (Cloud9)
- 29. Example • Email Notifier
- 30. Spark Core • WiFi (for IoT) • ARM Cortex M3 • 72MHz • 128kB Flash • USB2.0 • 12 bit ADC • USART, SPI & I2C • Breadboard Friendly • 18 I/O pins (3V) logic
- 31. Open Source Hardware OSS-type of License Electronic Design Files • Schematic • PCB Layout • Firmware OSS Mechanical Design • 3D models etc
- 32. Is it Really?
- 33. Intellectual Property • First to market • Community loyalty • Often crowd-funded (E.g. Spark Core) • Keep the trademark release the design • Sell Kits, educational material • Sell training, consultancy, education
- 34. Why don’t individuals make their own? • They do, that’s fine • BUT • Its easier and probably cheaper to buy one made using economies of scale
- 35. OSH Examples • Microcontroller / Computer Boards • Arduino • Raspberry Pi • .NET Gadgeteer Boards (Even .NET on OSH) • BeagleBoard • Spark Core
- 36. OSH Examples • Modules • GPS • Microphone (Preamp) • Motor Drivers • PIR Sensor • etc.
- 37. OSH Examples • Tools • RepRap - 3D printer • Maker Bot - 3D printer • Lasersaur - Laser cutter
- 38. Where does this leave the expert? • Makers often lack deep understanding and engineering discipline. • Young Makers attracted to Engineering disciplines • ‘Make more value than you take’ (Tim O’Reilly)
- 39. Summary • Hobby Making moving from cakes and woodwork into high technology • Tools to help • Information to help • Communities to help
