What aresmart things

What isInternet of Things

Internet of things ( IoT ) – unified ecosystem, that allows smart things to communicate between themselves and humans

What isInternet of Things

In IoT events of real and virtual world are monitored by sensors, information is transferred by networks using specialized protocols and as a result of event data analysis some meaningful actions are made

Who are inInternet of Things

•Smart things new world•Smart things as open systems•Tools•Why care on hardware•Why one needs to test now

Talk scope

•Smart things security•Ethics and Big Brother•Industrial design•3D print•Manufacturing

Talk out of scope

Embeddedsystems

• Long term test• Strict regulations• Solution scope• Users

• Fast ideas try-out• No rules• Changing

Life cycle ofDIY

Smart thingIdea

Development

Prototype

Manufacturing

FAIL!

Everythingcan go wrong

Tools

• Electrical tools• DIY tools• Serial port

Small toolboxArduino

Raspberry

+ electrical tools

Big toolbox

• Integrate ready kits• You can find everything in China• Select carefully• Don’t fear to burn• You can make your own mecanics

Polymorphus

Fast mechanical prototypes

3D printing for poor: Polymorphus – 20 cents3D print – 20 bucks

Serial port

• Port speed• Voltage• Timeouts• Control codes• Transparent network

Breadboard(with breaks)

There is a voltage line break – half board is powered

FAIL!

Frequencies mismatch

Chinese kits are different

FAIL!

8MHz here16MHz here

Software relies on 16MHz

Configurationcan be soldered

If jumpers aresoldered wrongthen…

FAIL!

Current consumption

WiFi takes up to 1A

Engine start modulecan be expensive

FAIL!

WiFi may drain your car battery overnight

Chineseflash cannot handlemore than 10-20 reflashes

FAIL!

Even ready-made kitscan fail

You can haveeven more fails

• Long wires• Static network settings• No more components manufactured

Worst fails:• smart thing is meaningless• smart thing don’t work in ecosystem

• IoT Security• IoT Analytics• IoT Device Management• Low-power networks• IoT Processors• IoT Operating Systems• Event Stream Processing• IoT Platforms• IoT Standards and Ecosysems
