Abstract

-A Cassava Press is a tool used in many parts of the developing world for increasing the longevity of food by pressing part, or all of the liquid out of the food. Many cassava presses are very large (about the size of a washing machine) and allows for the village people to preserve a large amount of food at once, either for personal use or to sell in their micro-economy setting. The cassava press designed as a piece of open source hardware is a small scale press that could be used in a household, or for personal use if needed.

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer

Technical Specifications and Assembly Instructions

  1. Provide directions for print/assembly - be detailed enough in your “how to” to ensure that someone could construct the device from your description. Consider the elegance of IKEA like instructions.
  2. Include print time estimate
  3. Include assembly time estimate
  4. Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
  5. Consider video if appropriate
Example video summary of textbook
Error in widget YouTube: Unable to load template 'wiki:YouTube'

Common Problems and Solutions

  • Include common mistakes/problems to avoid in building your OSAT and how to overcome them

Cost savings

  • If your solution is not a low cost one then it is not really appropriate.
  1. Estimate your costs
  2. Find a commercial equivalent
  3. Calculate $ savings and % savings

References

  • The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> 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]
  1. web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://www.eren.doe.gov/erec/factsheets/landscape.html

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 [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
