Yes, the LT3080 had protection and other issues.

Having just waded through this long thread from beginning to end, it seems nobody made the observation that seems important to me:
Regardless of the physical design and layout of the display, the important thing for an open design is that the information to be displayed and the interface to communicate that information is documented. As long as the interface is well defined, the use of a custom manufactured part is no longer a major problem. Anyone with knowledge of the interface can design a replacement for the display using any technology they like.
That's the key thing about systems design: modules and interfaces. Once you define the interfaces, you can redesign and replace any module with a different implementation as long as it preserves the same interfaces.

So now LT3081? or you reverted back to using transistor pass element like npn or n-mosfet?
I have used n-mosfet in my design with sepic pre-regulator (1v dropout) and it worked fine after help of others and countless iterations. I remember you saying that you want an off-the-shelf solution and that is why you picked lt3080, I wonder if you changed your mind now.
In any case, I vote for another video series about the subject :-+ at least one video to explain or walkthrough the circuit.

Dave said in post #66
"and right down the bottom:
5) Think about were OSHW comes into it."
This thread is not supposed to be a place for OSHW discussion (post #94) so it might help if it wasn't referred to as an open design since that is a right down the bottom of the list consideration. And possibly an unwelcome distraction.
If you want to start a discussion on OSHW in another thread people might be interested in considering custom components as part of the equation.
