if i may be so kind as to make a suggestion?........if you go to belt gizmo under the search bar, you can find a printout of the actual circuitboard that was used for the belt gizmo. simply print it out on gloss paper in best print and cut yourself out some thick plastic and pretty much just follow the guide on how to build it. this is how i made mine, and i got some pretty good results! just a suggestion, thought it might benefit you, fellow buster!

wow,I really like your interpretations. Good work!
