I will finally have time to complete this project and publish all the code and remaining artefacts (e.g., focus motor control mechanical design files). The push comes from the need to have it done before mid-July so I can use it as part of some university summer camp sessions. Volunteered to help with beginning Arduino programming for grades 7-9 and very much looking forward to it.

It is only the focus control that needs to be completed and it should be easy enough to build on the existing design and code base.
