777 OSAT projects 2016

Assignment

1. Identify an OSAT that you would like to design to be a 3D printable technology
2. Make sure someone else has not already done it : existing designs here. Also check former years 2014 and 2015(You can choose to do a major improvement on past design)
3. Reserve your OSAT by signature tagging with ~~~~ next to the OSAT on the list generated by the Appropedia community: Requests for 3-D printable open source appropriate technology. You can add your own ideas to the list, more than one of you can tackle the same tech in a different way, you may improve upon existing designs if you do so in a significant way. Double check someone else has not already done a better job - use http://yeggi.com Do this by 11/15
4. Design 3D printable components with ONLY OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender) for FreeCAD put on https://www.youmagine.com/ and link back to it on Appropedia.
5. Create an Appropedia page for your project. (Easiest way to create a page is put double square brackets around your project title on the reservation list - this will create a red hyperlink to it)
6. Include the following sections on your page using the template below (copy and paste wiki markup into your page)
7. Add picture and link to your project page in gallery below.
8. Print component and bring to class - Complete and due by 12/6

References[edit | edit source]

• The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the and <references /> tags and can be in any format but should include all the information necessary for someone else to find the same information you did. For example:^[1]

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use . Be sure to categorize your device so that it will be easy to find – for example "Low voltage connection basics" is categorized in .
