Small Electronics for Your Makerspace Arianna Schlegel CLC Trendspotting: The Technologies of Makerspaces 26 March 2014 Fairfield University
So many options…! The Connected Home: Which Board Is Right For Me? (2/7/14) MAKE magazine, volume 36 Inside: an illustrated glossary and projects, plus more in-depth discussion of each board.
3 Main Categories 1.actual computers 2.sensory processors 3.wearables
First: What is I/O? Stands for Input/Output - think of your five senses. Those are input. How you process and respond to those senses? That is your output. What kind of I/O do the PCs sitting in front of you have?
1. Raspberry Pi • is actually a very tiny (single-board) computer running Unix • not a ton of processing power for $35...but it’s only $35 • can be written & rewritten over ad infinitum • need some project ideas? http://makezine.com/category/electronics/raspberry- pi/
Some Raspberry Pi Project Ideas 1. Use OpenElec to make your home TV a mini media center 2. Use Chromium to web surf on your TV 3. ArcadePi or gaming (Minecraft) 4. Go vintage with Windows 3.0 5. Write some code! (use the included Python compiler, start with Scratch, or choose from many others) 6. Robotics 7. Learn hacking skills 8. Make a server (BitTorrent, cloud) 9. Make yourself a weather station 10. Or your own touchscreen “tablet” 11. If you’re ambitious, your own quadcopter 12. Even a beer cans keyboard (with a little help from Arduino)
1. BeagleBone • “designed for makers” - designed from the ground up to work with hardware (sensors, etc.) • like Raspberry Pi, it’s also an entire computer and also runs Unix • moved the operating system from the SD card to the board itself • costs $45 (down from $89)
Not sure which to choose? MAKE magazine to the rescue again! How to Choose the Right Platform: Rasbperry Pi or BeagleBone Black
1. Gizmo Board An x86 board which MAKE magazine calls “essentially a laptop on a single board” that is “blinding fast, extremely flexible, and hugely powerful by the standards of those of us coming from the microcontroller world.” Cost: $200 http://www.blogcdn.com/www.engadget.com/media/2013/01/amdgizmosphereboard.jpg
2. Arduino • first of its kind (a single-board microcontroller) - designed as a platform for makers • began as a project to give artists the ability to embed microprocessors for use in interactive pieces (like my dad’s, below) • many different flavors • used primarily for sensory computing • available in a lot of places (Radio Shack, Amazon, online) • costs ~$35-$100, depending on features & power • tutorials here
2. The many faces of Arduino (And these are just the official & current ones!) See here for a still incomplete but much longer list... Yùn ~ Leonardo ~ Uno ~ Due Mega2560 ~ Ethernet ~ Fio ~ Nano LilyPad ~ Pro ~ Mega ADK ~ Esplora Micro ~ Mini
Some Arduino Project Ideas 10 Simple-But-Fun Projects to Make with Arduino (all call for an Arduino and a USB cable) LEDs resistors breadboard & connecting wires capacitors push buttons network cable battery tester electronic dice traffic light stopwatch digital clock a Twitterer
Some Bigger Arduino Project Ideas 10 Simple-But-Fun Projects to Make with Arduino (all call for an Arduino and a USB cable) DFRobot 2A Arduino Shield ($16) 9V battery to DC socket cable (2 for $3.53) Alkaline AA batteries (48 for $12.50) Pololu RP5 Chassis plate (10 for $6.25 each) Pololu RP5 Tank Chassis package (10 for $44.96 each) SparkFun GPS shield kit ($59.95) LCD module or Freetronics LCD shield ($29.95) robots 1 1 6 1 1 a GPS generator 1 1 1
2. DigiSpark • PROS: o costs just $9! o small and lightweight o works like an Arduino • CONS: o less powerful (for more power, see the TinyDuino)
2. TinyDuino • Costs $19.95 (or $39.95 for a basic kit) • GPS Cat Tracker (the ideal “typical librarian” project)
2. TI LaunchPad • $5-$10 • less - 14 I/O pins (vs. 20 on Arduino) and 16K (vs. 32K on Arduino) • used to be difficult to program on, but they have released a new, open source platform (Energia) which works on all OSes • you can also use your Arduino code on it!
2. Netduino • very different from the Arduino, despite its name • you have to know how to program in C#, and it’s mostly restricted to Windows computers • costs $35
2. Parallax Propeller • can control 8 things at one time • costs $50 • good for robotics
2. AVR Butterfly • the size of a name tag, which is what it can be used for! • includes an LCD screen, joystick, speaker • costs $20 • NOT compatible with Arduino code
2. MaKey MaKey A fun beginner project that anyone can do! Takes no time at all to learn & set up, and appeals to all ages.
3. Lilypad, FLORA, & GEMMA Arduino board designed for wearable computing. (BONUS: They’re waterproof!)
Some other great examples... Becky Stern is the wearable tech goddess! Watch her Adafruit tutorial videos here: http://www.youtube.com/playlist?list=PL2B8A7560BC19F361 Which to use? FLORA vs GEMMA according to Becky.
FLORA ($25) or GEMMA ($8) projects 1. Amplitie 2. Firewalker Sneakers 3. Pac Man Suspenders
Just FLORA projects 1. PianoGlove 2. GPS Jacket 3. Citi Bike Helmet
Just GEMMA projects 1. Space Face Galaxy Makeup 2. NeoPixel Ring Bangle Bracelet 3. NeoPixel Tiara (A NeoPixel costs $25 at Adafruit.com)
3. the TinyLily From the makers of TinyDuino, “tiny washable circuits for e-textiles”:
My first (misguided) project www.youtube.com/embed/nFjQWA FEo48
For your advanced users: FPGAs (field-programmable gate arrays) that start you with a blank slate - you must design the chip at the hardware level, so you can dictate precisely how things work. (This is good to know for those who want to work for electronics companies like Intel.) The Papilio (http://papilio.cc/)
And many more! There are dozens of options out there now. You will have to decide which is right for your library’s needs and community. To consider: price, learning curve, available tutorials quality, features, intended use
Evolution Continues These boards are constantly being worked on - new types are regularly introduced. The latest? Wireless capabilities (Yún) and hybrid boards. But things won’t stop there. Keep up to date with the latest boards on places like http://makezine.com/category/electronics/ or http://www.adafruit.com (they call them “Dev Boards”) or Kickstarter (seach on “arduino”).
Need To Know UNIX (learn here: http://www.ee.surrey.ac.uk/Teaching/Unix/) ...or... Arduino code (C or C++) (learn here: http://arduino.cc/en/Tutorial/HomePage) (But PLEASE don’t let this scare you away!) #1 #2 and #3
Where To Learn • Adafruit (highly recommended) • MakeZine.com (Weekend Projects) • YouTube • books (like Make: Electronics or Encyclopedia of Electronic Components, Volume 1) • fellow enthusiasts! (at other makerspaces?)
