  16. 16. My experience on RepRap project Mendel Prusa Mendel I started in 2009 having no clue about HW and electronics!Wednesday, June 15, 2011
  17. 17. Free stress-less education You can learn what you want, when you want, how you want. In my case: No HW and electronics experience 18 months Successful printer redesign 6 months Book published by O’reillyWednesday, June 15, 2011
  18. 18. 2009 Mendel • Smaller • Faster • Faster to replicateWednesday, June 15, 2011
  19. 19. 2010 Prusa • Almost no bearings, using PRINTED alternatives • Build time reduced to few days for newbies • Half replication timeWednesday, June 15, 2011
  20. 20. In 3 years almost the quality of commercial printersWednesday, June 15, 2011
  21. 21. New printersWednesday, June 15, 2011
  22. 22. Number of printers • nobody really knows, most of the printers are crowd-sourced • Erik de Bruijn estimated in his thesis between 3872 and 4840 people in the community (October 2010) • But what we know for sure, community grows exponentially!!Wednesday, June 15, 2011
  23. 23. Printable objects are easy to be open sourcedWednesday, June 15, 2011

  29. 29. Printable parts We are living in the Lasercut internet of things parts That means, we can share real Hardware online! Simple PCBs How-tosWednesday, June 15, 2011
  30. 30. We just don’t know how to organize it ...yet! http://thingiverse.com - mess http://instructables.com - even more mess ...Wednesday, June 15, 2011
  31. 31. You can publish only completed projects. With hand tailored documentation. Software has better solutions! They can make documentation automagically! JavaDoc, PHPDoc, ...Wednesday, June 15, 2011
  32. 32. ThingDOC solves that! It can generate your HW project documentation. Works on simple text comments. Printed parts, lasercut parts, ... ThingDOC is being developed on Prusa Mendel RepRap parts.Wednesday, June 15, 2011
  33. 33. Generator isn’t lazy! Normally you have to change documentation with every update of the design! Thats hard if documentation is long as small book and you update the design twice a day! 1) Errors 2) Out of date documentation It causes: 3) Demotivates to update design often 4) If you use wiki, its hard to find older documentationWednesday, June 15, 2011
  34. 34. Forking is hard!Wednesday, June 15, 2011
  35. 35. With ThingDOC every thing in project has it’s own info about properties and relationships!Wednesday, June 15, 2011
  36. 36. So when you update or switch one file, you still can get full featured documentation! Means: Easy forking! Easy updating!Wednesday, June 15, 2011
  37. 37. Documentation is hyperlocal! Informations about the object are embedded in the same file!Wednesday, June 15, 2011
  38. 38. What ThingDOC can do? • Bill of materials • Info about things • Assembly instruction • Structured data of your project All in many formats! HTML, TXT, PDF, WIKI ...Wednesday, June 15, 2011
