Prototype video is now live.  You can view it here:

Hopefully will take some time this week to break down the various parts and discuss what I like and didn't like and what changes will be made to the next version. 

As an aside, I realized in filming the video how easy and tempting it is to hide design flaws and "oversell" a product.  I think this happens a lot in particular with 3D-printing related projects, and probably one (of many) reasons Hackaday, YouTube, and Kickstarter are a graveyard of exciting prototypes that never made into final products.  In my case, if I'm honest, the ratchet system is pretty "gimicky" right now, but I think I know what to do to get it functioning the way I like it.  But that doesn't really come across in the video. 

Two takeaways:
1. There is a lot that YouTube videos can hide or embellish
2. It is important to involve real users early and often to detect these types of shortcomings before it's too late.

That's all for now.  Like I said, more breakdown coming, so hold tight for that.  In the meantime, feel free to share your thoughts on your takeaways from the video.  What do you like?  What has you raising an eyebrow? What could be improved?  Let me know.
