Hey Dan,
There will be a set of plans available. I still have a few kinks to work out first. I think I am also going to make an instructional video on how to make it included with the plans. I need to make another one with the new design changes before I can finalize a set of plans that will work easily. The prototype works great, I just want to tweak the pattern so that it is easier to make and more reliable. Not sure how long it will take to make the changes but it shouldn't be too long.
