Hi HN, I'm a long time hacker who's always wanted to give inventing a try, despite not having an engineering background.
What are my best bets for experimenting from my computer?
They seem very expensive, but Would I need something like Hyperworks, Autodesk, or Wolfram?
I'm noticing some interesting open source projects here:

Are any of these worthwhile?
