I admire your honesty and tenacity with this project. When you posted images of the first working camera I posted some negative comment on this forum suggesting the rail design had serious flaws. I note too no one else was prepared to critisize the design.
Well things have moved forward and you've made some positive changes, both design and commitment to your customers. We all make mistakes but not many would be willing to front up on a public forum and openly admit to them.
I look forward to the successful completion of the new prototypes.
