The source code and installation instructions for a fairly robust example of a Drupal based Electronic Lab Notebook (ELN) has been posted on GitHub at https://github.com/MyLabBook/mylabbook. An associated community site has also been updated at https://mylabbook.org with a video describing the installation, documentation, screenshots and other background material. Plans are to continue to improve this platform and continue to utilize the robust capabilities of Drupal to provide a low cost and capable ELN that matches or exceeds the capabilities of many commercial ELN packages.
Please try it out and provide any feedback using one of the venues as shown on the contact page at https://mylabbook.org/contact.php.
