I converted this recycling bin into a giant jack-in-the-box. And then I surprised people with it.
To build the giant jack in the box, I initially attempted to quadruple the size of a small kitchen scale that used a mechanism I thought would be perfect inside a recycling bin. I call the part that moves up and down the carriage. I designed it in Solidworks and laser cut duron piece and glued them together. I used wooden dowels as the pivots and fasten them to the rotating parts on the carriage. It quickly became clear that this would be too bulky and unsteady at such a large scale. [Lots more about process after the jump!]
