Agenda

•What is IoT•What is the Raspberry Pi (2 or B)•What is Windows IoT Core•Why .NET

IoT has history

Why should we care about IoT?

How many things are out there?

Security

IoT Hacking – too easy

IoT Hacking Examples

• The ZigBee protocol – widespread and not secure•Philips Hue “Smart” lights – 2013• Fitbit infected with malware – 2015•Baby Monitors insecure• IoT devices require too much data

Raspberry Pi (2 or B) • Broadcom ARM 7 Quad Core CPU at 900MHz

• 1GB RAM• 40pin extended GPIO• 4 x USB 2 ports• 4 pole Stereo output and

Composite video port• Full size HDMI• CSI camera port for connecting

the Raspberry Pi camera• DSI display port for connecting

the Raspberry Pi touch screen display

• Micro SD port for loading your operating system and storing data

• Micro USB power source

Arduino• ATmega328 microcontroller• Input voltage - 7-12V• 14 Digital I/O Pins (6 PWM

outputs)• 6 Analog Inputs• 32k Flash Memory• 16Mhz Clock Speed

MinnowBoard• Intel Atom CPU dual core

1.33GHz• Integrated Intel HD Graphics• 2GB DDR3 RAM• 8 MB SPI Flash• 1 x Micro SD• 1 x SATA2 3Gb/sec• 1 x USB 3.0 (host)• 1 x USB 2.0 (host)• 1 x Serial debug - via FTDI

cable available separately• RJ-45 Connector for Ethernet• Micro HDMI

• Easy transition• Familiar environment• Full support for standard Universal Windows Platform (UWP)• C++, C#, JS, VB.NET• Python• Node.js• Improved tooling and debugging experience

Windows IoT Core & Developers

• Because I can• Because it's easy if you're a .net dev• Because it's familiar and you can use the same tools• Caveats• WiFi doesn't work with all USB adaptors• Subset of .NET Framework• Serial Port drivers are not available yet• USB is mostly functional and can be an alternative to the standard

serial port• Only Windows IoT approved hardware works (i.e there are no

drivers yet)

Why .NET on Rpi 2?

Setting Up Rpi 2

• PowerShell• Web Page (<IpAddress>:8080/AppXManager.htm)• Some things can only be configured through PowerShell

WunderBar

• Was this the right choice?• Very easy to set up but expensive• It uses it's own backend but the data is volatile and not persisted

Summary

• Exciting technology• Fun to work with• Be aware of the security implications• What about the moral implications?
