IoT Printer

A presentation at IOT London, about http://exciting.io/printer, the IoT printer platform I built a few years ago

Transcript

1. “An open-source distributed platform for IoT printers” James Adam - @lazyatom - @freerange If you’re bored: bit.ly/printermail :: bit.ly/printerpaint Text
2. Disclaimer: I don’t know what I am doing.
3. Project Codename: Timmy Printface gofreerange.com/timmy

10. The problem with hacks is that they are hacky.

16. The Goal: Make it less of a giant ugly hack.
17. Printer. gofreerange.com/printer
18. Cheap printer Ethernet shield Arduino Some LEDs, etc
20. Poll a special URL Emit data via serial Manage some LEDs and maybe a button?
24. Content Services produce HTML pages, and post URLs for those pages to Backend Servers.
25. Backend Servers expect URLs to HTML pages... ... and converts them into 1-bit images, then serial commands
26. Printers download serial commands and send them directly to printer peripherals.
27. Content generation is easy in HTML
28. Content can come from many places
29. http://backend1/print/abc123
30. bit.ly/printermail
31. bit.ly/printerpaint
34. No central server either
35. Two Backend Servers using the same Content Service
36. •Other people are better at design than I am; •Other people have better ideas for content that I have; •So: make it easy for them to produce and print content, from which everyone benefits. The Plan:
39. •HTTP Header parsing •Running out of space on Arduino •Reliable networking is hard •Programming in C is a pain in the fucking ass. TODO
