Why Hardware Hacking? Arduino  3D Printing  Laser cutting  CNC milling  Conductive Ink printing  DIY Communities, FabLabs  Fig.1: Pebble Smartwatch [3] YCombinator:   7/84 startups make hardware [1] Pebble Smartwatch:   $10 Mio funding on kickstarter [2] [1] http://www.paulgraham.com/hw.html [2] http://bits.blogs.nytimes.com/2012/05/11/pebble-smartwatch-tops-out-at-10-million-on-kickstarter/ [3] http://getpebble.com/ 7

Creating Opportunities for Research New hardware makes people explore new research questions  Fig.3: Microsoft Kinect [2] Fig.2: Wii controller [1] Researchers who can build new hardware can open up new domains  [1] source: http://www.nintendo.com/wii [2] source: http://www.xbox.com/en-US/KINECT 8

Designing a hardware platform for ubiquitous computing research Trade-offs   Self-contained vs. extendable  Size and weight vs. DIY friendliness Requirements   Processing  Connectivity  Sensing  Actuation 9

Lessons Learned from Smart-Its Modular open hardware is great. Miniaturization is key to move beyond proof-of-concept implementation DIY is not enough… 10

Lessons Learned from Arduino - More than one form factor required Development support / programming language is key Powerful computing and multimedia are tough 11

Lessons learned (from Gadgeteer) Need for lighter SDK Form factor and energy consumption matters 12

Recent Prototyping Platforms 13

DIY HW platforms range …. Raspberry Pi / Beaglebone Seeeduino Film / Xadow high processing power low processing power • • (700Mhz-1GHz) ( 8Mhz) credit card sized small size • • high power consumption low power consumption • • (5V – >500mA) (3,3V – 1,2uA / 3mA) 14

Arduino - MCUs Arduino   Uno  Mini  Micro  Funnel IO Seeeduino Film / Xadow  15

Arduino - Seeeduino Film Atmega168 – 8Mhz  3,3V - 1,2uA / 3mA  Flex Bus (20 pin)  Chainable  Cutable  16

Arduino - Xadow ATmega32U4 – 16Mhz  3,3V  Flex Bus, Chainable  Many components (OLED, BLE…)  Micro USB (progr. /charging)  http://xadow.cc/ 17

Arduino – Funnel IO (FIO) ATmega328V running at 8MHz  0.1mA / 3.8mA  Xbee Socket  Lithium Polymer battery connector  Charged via mini USB  18

.NET Gadgeteer FEZ Spider Mainboard  (ARM7, 72MHz, 16MB RAM) > 100 modules  19

Electric Imp MCU with embedded Wi-Fi  SD card size  Initial setup via Phone-App  Programming via Web IDE  Cloud / client components  Language: Squirell  20

Electric Imp – Quick Demo Live Demo: Webbased IDE  21

mBed  ARM Cortex M0 – M4  30-204Mhz  USB storage drive  Web IDE  C/C++  Social coding, Code DB, GIT integration  Cloud optimized compilation  -- Debuging with Web IDE  Desktop IDE 22

Credit Card Sized Computers RaspBerry Pi   700MHz, 512(256)MB RAM  cost 25€ (!!!) BeagleBone   1GHz, 512 MB RAM  cost 55€ Full OS: Linux, Android,…  Easy extension with USB  Output via HDMI / audio  Many IO ports, no Ain  23

Blidgets Platform 24

Blidgets Brand new Rapid Prototyping platform created at HCILAB Stuttgart Ultra-low power (<1uA sleep / 30uA)  Powered by coin-cell, LiPo battery or external supply  Bluetooth Low Energy wireless connection to PCs and smartphones  18 GPIO ports, 5 Ain, 4 PWM, UART, I2C, SPI  Vertically stackable and horizontally chainable  Tiny form factor : 3g, 25x25x4mm  Instantly programmable and controllable trough a Web based UI  JavaScript for programming system logic  25

Blidgets - Extensions 26

Blidgets – Web IDE Quick DEMO 27

T owards a Unified Platform 28

Before Hands-On: Q&A 29

Hands On! (finally…) Four workbenches: mBed (Web Based IDE, C)  Electric Imp (Web based IDE, Squirell)  Xadow (Arduino IDE, Wiring/C)  Blidgets (Web based IDE (Alpha!), JavaScript)  For the first slot please choose one platform (now)  For the second slot choose another platform (later)  Use the instruction sheets to get started  30
