Please read the rules of the Completed Projects forum.

When posting a project please include the following information:

1. A clear title that describes the project appended by the word 'Project:', for example "Project: 555 Audio Oscillator".
2. A list of parts, equipment, software used.
3. Details of any theory, references or information that may be applicable.
4. Any schematics, source code, etc.
5. A short description of what to do.
6. In the interests of manageability and security, project files/code/schematics must be locally stored. Links may be used to provide supplementary information, however they must not provide the substance of the project.

This project is not using this site to host the documentation, or meet any of the other above requirements. If you want to resubmit this entry please rework the entry to meet the requirements, then drop one of the moderators a PM. If it is acceptable a moderator will move it back to the Completed Projects forum and clean up notices and suggestions like this one (making them invisible).

All documents must be hosted locally. AAC allows for attachments and albums, use them. You Tube video links are allowed, but they in no way constitute proper documentation.
