It is not the first time Nico71 (Nicolas Lespour) does something like this. After his Pritz Hatchet Planimeter a couple of weeks ago, he built now a LEGO Orthogonal Planimeter!
The concept and first implementations behind this great piece of engineerin, was developed during the 19th century according to this Wikipedia article about the Planimeter.
A planimeter (also known as a platometer) is a measuring instrument used to determine the area of an arbitrary two-dimensional shape. By traveling the boundary of the shape, the measuring instrument integrates the area of the shape which is equal to the surface defined by that shape.
At Nico71's blog, you may find additional information and building instructions for his LEGO Planimeters.
Please avoid sending requests to post specific models on this TBs section.
We understand some of you would enjoy to see your creations featured here, but please understand that because only one video gets highlighted per week, it is impossible to accommodate all the great MOCs continuously build by the Technic builders out there. They simply won't fit all and that's also not the purpose of this blog (see the header statement).
Many of your MOCs are scanned anyway and listed for later publication when they do not fit immediately. However some remain in the backlog queue just for too long and eventually loose the relevance or the publication opportunity window. As a rule of thumb, we also avoid publishing MOCs that have been featured by their authors or other fans at some other great web places dedicated to the Technic community out there. It doesn't mean that occasionally some won't get published here anyway.
Thanks for your understanding!
