Some time ago I liberated several ball screw linear rails from the scrap bin at my workplace. I used four of them to make a CNC router. I gave a few away. I have one left. So what to do…. What to do… MAKE A BUBBLE MACHINE!!!! There are many home made bubble machines out there, so I wanted to create something different using the ball screw slide. Therefore what I envisioned is an Arduino version of the old I Love Lucy candy packaging skit but as a bubble machine. So the concept was multiple bubble wand raising and lowering in a random fashion. Connected to the ball screw slide is a fan. When the wand is raised and ready for blowing, the ball screw positions the fan in front of the wand and blows the bubbles. After set time of blowing bubbles, the wand lowers to recharge with bubble solution and the ball screw slide moves to the next available ready to blow wand. I wanted this machine to be erratic in behaviour with the wands moving randomly and the ball screw slide furiously trying to keep up. So on with the build…”
