Plot Clock Arcrylic version

An interesting small project.This post should be the one who created it: http://hackaday.com/2014/02/13/a-clock-that-plots-time/ And also there are bunch of people who made their own versions: http://www.thingiverse.com/search/page:1?q=plot+clock&sa= http://www.instructables.com/id/Plot-Clock-for-dummies/ I also tried to make my own one but abandoned it for some reason.I modeled the whole clock in solidworks so that I can modify it to whatever I want.Also I wrote a small program to simulate the motion and found some interesting results.For those who want to scale the clock up and optimize it please check out my post below.I also open sourced my program so that anyone could use it for tuning the arm length.But don’t guarantee it’s bug free :) http://lichaoma.com/2015/11/25/simulation-of-plot-clock-for-optimization/ This version is for laser cut,for 3D printing version please go here: https://grabcad.com/library/plot-clock-3d-printing-version-1
