3. Why I'm talking about this?

4. Why I'm talking about this?
● Because Nakov made me!

5. Why I'm talking about this?
● Because Nakov made me!
● Because I'm a lazy ass :)

6. Why I'm talking about this?
● Because Nakov made me!
● Because I'm a lazy ass :)
● Because I have done some shits that have IPs

7. A bit of history for IoT

8. A bit of history for IoT
● It is NOTHING new!

9. A bit of history for IoT
● It is NOTHING new!
● in 2004 I did it with NO knowledge at all

10. ICMP PING

12. How did I do it?
● A small daemon written in Perl
● Some libs :)
– Net::ICQ::On
– Device::ParallelPort
– Device::SerialPort
● Aaaand... I stole the hardware from my brother :)

13. Ohm's Law
The things
you are
AFRAID

14. Things that scare you...

15. ● If you are interested, how to do it the OLD way...

Electrical-Control/

16. Why is now any different?
● We have platforms with many GPIOs readily
available to users.
● We have easier access to these GPIOs with
simpler kernel interfaces.
● We have development boards, schematics and
examples.

17. Why would you want to build your
own IoT device ?
● Because it is FUN

18. Why would you want to build your
own IoT device ?
● Because it is FUN
● You can tailor it for your need

19. Why would you want to build your
own IoT device ?
● Because it is FUN
● You can tailor it for your need
● You can change it as you want

20. Why would you want to build your
own IoT device ?
● Because it is FUN
● You can tailor it for your need
● You can change it as you want
● Because you will have full control

21. IoT now
● The hard decisions:
– Micro controller
– Full PC

22. IoT now
● The hard decisions:
– Micro controller
● Arduino based
– Arduino UNO 46lv
– Olimexino 44lv (the most expensive one)
– TinyDuino 20$
● ESP8266 11lv
– Full PC

23. Arduino UNO

24. Olimexino

25. TinyDuino

26. TinyDuino SIZE

27. ESP8266
Kudos to Olimex for making these!Kudos to Olimex for making these!

28. IoT now
● The hard decisions:
– Micro controller
● Arduino based
– Arduino UNO 46lv
– Olimexino 44lv (the most expensive one)
– TinyDuino 20$
● ESP8266 11lv
– Full PC
● Raspberry Pi 84lv
● OlinuXino 90lv (the most expensive one)
● VoCore 20$
● Spark I/O 39$

29. Raspberry Pi 2 B+

30. OlimeXino A20 LIME

31. VoCore

32. Spark I/O

33. IoT pereipherials
● Sensors
● Communication
– WiFi
– Bluetooth
– Xbee
– RF 315MHz 433 MHz
– RFID & NFC
● 3D Printing for case prototypes

34. But how to organize everything
● Olimex proposal
● Spark I/O proposal
● My proposal

35. Olimex proposal
● Every IoT device should be directly connected to
the internet
● Pluses:
– easy installation
– easy access
– every IoT device can be made to do everything
– easier to create cloud offerings around this type of
devices
● Minuses:
– Security
– Too much resources wasted
– Either cables or good WiFi required

36. Spark I/O proposal
● Every IoT device should be directly connected to
the internet
● Eevery device should be programmed from the
cloud
● All data should be stored in the cloud
● Pluses:
– easy installation
– easy access
– easy programming
– every IoT device can be made to do everything
– easier to create cloud offerings around this type of
devices

37. Spark I/O proposal
● Minuses:
– Requires working WiFi
– No possibility for offline programming
– All your data is located outside your home
– Does not work as expected without Internet
– Security
– Too much resources wasted

38. My proposal
Hybrid, have one OLinuXino act as a server
Connect all other IoT devices to it via API
● Pluses:
– Very secure
– You have greater flexibilty
– You can combine any type of connectivity
● Minuses:
– More complex setup
– One more device to keep at home

39. My latest work :)
● Convert this...

40. My latest work :)
● Convert this...
● Into that...

41. My latest work :)
● Convert this...
● Into that...
● Why?
● Simply because I'm too lazy...

42. Thank you...Thank you...
