The Rainbow Bubble Machine


Version 3.0 - smaller, less complicated gear

This is the final version of the Rainbow Bubble Machine, as I have pretty much given up hope on this project.

Replaced a bunch of gear wheels by a worm drive.

Many likes and positive comments in different places around the LEGO community made me happy though.

Bad luck for "the LEGO guys" that they miss the chance to turn this very special machine into a set, that makes everybody smile who watches it do its wonderful work of colouring the world.

The instructions can be found online now.

A look inside



The Rainbow Bubble Machine - now single motored, smaller.

By rearranging the arm I managed to use one motor to drive pump and arm. The design now also needs much less space and thus fits a smaller plate.
