Apr 02, 2019 I was looking for a CALCULATOR flowchart, not an expression parser which is what the SHUNTING YARD algorithm is. As a matter of fact that is used quite a bit in the RetroBasic that I wrote, and posted about on this forum sometime last year. What I needed (and have since figured out) is the flow of events for a 4 function calculator, what happens for each key press, moving data from input.
Super cool program: Trebstar, a Mac and PC trebuchet modeling software, calculates the range and efficiency of your trebuchet design.
The program has various configurable parameters and animations, and also shows the forces on the different components of the trebuchet itself – lets you know what part might break when you build your masterpiece. A handy tool for aspiring punkin chunkers! And a quick reminder: watch me on Science channel’s Punkin Chunkin special this Thanksgiving. It’s awesome.

Here’s a miniature trebuchet kit to let you understand the mechanics while throwing golf balls around the back yard (or office).
