5. Why SBCs?
6. How SBCs differ from other computers
9. Choosing an SBC
11. No Wifi, no Ethernet Raspberry Pi Zero Raspberry Pi 3 Uses USB based networking Has Ethernet, Wifi and Bluetooth and 4 USB ports Has two microUSB ports
13. Setup!
14. A bit more hardware… +
15. Linux for SBCs
18. Linux Setup • $ diskutil list • $ diskutil unmountDisk /dev/disk2 • $ sudo dd if=./2016-05-27-raspbian- jessie-lite.img of=/dev/disk2 https://goo.gl/hhJJRE
19. Boot time!
20. Networking • $ ping raspberrypi.local • $ ssh pi@raspberrypi.local • $ scp ftw pi@raspberrpi.local/home/pi https://goo.gl/hhJJRE
21. NodeJS Setup https://goo.gl/hhJJRE
23. $ mkdir nodejs $ cd nodejs/ $ wget https://nodejs.org/dist/v6.9.1/node-v6.9.1-linux- armv6l.tar.xz $ tar -xvf node-v6.9.1-linux-armv6l.tar.xz $ cd node-v6.9.1-linux-armv6l/ $ sudo cp ./bin/* /usr/local/bin
24. $ cd ~ $ node --version v6.9.1
26. So what’s next?
27. Hello World!
29. –@cjus “Playing with single board computers is really cool. Getting them to communicate with one another is even cooler!”
30. Connecting SBCs! • $sudo apt-get install {cool-app-name} • Install servers: nginx, redis, apache etc… • Create bots and connect with anything with a public API • Build messaging applications using rabbitmq, zeromq, MQTT
34. It’s demo time!
35. So what else can it do?
40. We’re ready for another demo!
42. The Hydra-Cluster is open sourced! https://github.com/cjus
