My original goal of this project is to develop a machine that can generate variable sizes of bubbles with smoke inside. User's voice amplitude and But as the time goes, some of the features I planned has been changed and here I will present the fabircation process and the result!
Retro game, Bubble Bubble! :D and Lady Gaga's outft for her cray performance.
I thought that it would be cool to have different sizes of bubble with fog that has good scent inside and give the user to feel of magic power to generate it.
Inspired by this mechanism, Iris, I modified the design to have it smaller size and make it able to be fabricated using plastic material and laser cutter.
CAD for IRIS mechanism for making variable-sized bubbles. Front, side, back side view.
Cool fitting on my head ;)
I went through lots of design iteration. First started with the mask version, then moved onto a hat version, finally a device with a handles and convertiable to place on a desk for interior design stuff.
MaterialsHere is the list of the materials required for building the bubble-smoke mask.
FabricationIn order to see how the fit goes with my face, I just printed the front part of the mask using Formlabs 2 using Clear resin.
This was for estimating the actual size compared to head (this was for the very first process when I was planning to make this project as a bubble mask, but I changed it to make it hold by two hands or putting it just on a desk)
Iris Mechanism Development
To make the outer structure of the bubble machine, I used a Derlin sheet(1/8'' thickness) and cut it using a laser cutter. To find the proper setting to cut it clean, I was testing by tunning the power and speed, PPI parameters.
And found that these following setting was good for cutting a 1/8'' thickness Derlin sheet
To fix the Bubble Iris structure onto the base, I cut the acrylic rod.
Bubble RecipesI used the "Mike's Stir & Go" bubble recipe on this site.
Test with different inputs
My first intention to start this project was controling the bubble size based on the voice level or the amount of the speach. So I tested to control the servo using the electret board I built for the 'Interface' week.
Demo!Fortunatley, I just got my device make bubbles like 30 mins before the final presentation. Before that it was just keep making a bubble film but not able to blow it out. I tunning the fan speed and the position relative to the bubble film was really important. Also, putting a cone-shape nozzle around the fan was helpful to make the air flow more focued.
