Here are my goals for the project

1. It should be cheap, it has to be less than $60 under $50 would be great.
2. I want to avoid any extra interfaces like the ELM327 because of the added cost and complexity.
3. It has to be simple to assemble.
4. The parts should be easy to find.
5. Be easily compatible with all OBD II protocols e.g. Standardized parts for all protocols.
6. The assembly should be well documented and stable e.g. Pictures used that are hosted on any third party site should also be imported onto the ecomodder site when posting. That way if the link to the image changes it will still be an attachment on the site as well.
