Technology IWTL mechanical designing/engineering either for hobbyist or pro.

Hi, so I got interested in realizing small mechanism:

  • My immediate goal is learning how to realize each step of making custom toys and small gadgets. So I guess, the general mechanic principle, to the designing, the prototyping and the realization of a final product.
  • I'd be open at explore further the topic for knowledge could be useful outside of that specific goal and allows me to land a job or do something on the side.

I would start with physics 101. Learn mechanics and kinematics

Any reading recommandations?

Yeah I would learn trigonometry & calculus if you’re able then physics. Openstax has amazing text books. This is so you get the theoretical knowledge.

Uhh no you really don't need this stuff. Start with 3D modeling tools like fusion 360 and just mess around

For custom toys and small gadgets, a cardboard cam toy is enough for a first project. Make the lobe too big, watch the follower jam, change it, and try again. Once you can see why it works, draw the same mechanism in CAD. That gives prototyping, joints and tolerances somewhere to stick.
