What is the Amazon Echo?

A voice-controlled, internet-enabled, device providing a natural-language interface to services you may use already. A relatively easy-to-program front-end for any service requiring a simple interactive UI.

2 speakers
7 microphones
Bluetooth
WiFi

SLIDE 5

What is the Raspberry Pi?

Very small low-power single-board computer.

Runs Linux
Supports 1080p via HDMI
Provides a lot of I/O pins
Model 3 is quad-core 64-bit PC with WiFi

and Bluetooth built in

Vibrant community
$35!!!

SLIDE 6

What is IoT?

Network of everything
Often small Internet-enabled devices but

includes vehicles, back-end services, mobile devices, and appliances

50 billion objects predicted by 2020

(Cisco)

Big data nightmare opportunity
Resilient to network interruptions

Adafruit Huzzah vs Adafruit Wiced Feather

Huzzah Breakout

9 GPIO
No TLS 1.2 (i.e. no AWS IoT)
FTDI cord required ($15)
$10 ($15 in Feather form factor)

Wiced

More GPIO
TLS 1.2 (AWS IoT)
Micro USB
LIPO Battery charger built in
$35

SLIDE 19

Raspberry Pi vs Adafruit Wiced Feather

Raspberry Pi

Full Linux PC
Multi-core
Low power
Video out
$35!!!

Wiced Feather

Single core/single thread Arduino

compatible

No interrupt-based OS--better for timing-

critical I/O

Lower power
$35?!
