Fourth Team Meeting

Again, all team members were present at this meeting.

We built the remaining parts for the machine, and then built a representation of the machine on Solidworks.

Part to connect the Servo Motor to the Bubble Wand

Propeller to cause the fan, which will be attached to the DC Motor

Stand to raise the DC Motor. Will be attached to the DC Bracket

Dish to hold the bubble solution. Will be placed in a hole in the base of the machine.

Base, which all parts of the machine will be mounted to. The arduino board will be underneath the base, and the wires will be fed through the small holes in the base.

Below is the model of what the machine should look like when it is done.

Third Team Meeting

All team members were present at this meeting.

Many parts were created, including models of the servo motor and the DC motor so that we could use them in the Solidworks representation of the machine.

Model of the DC Motor

Model of the Servo Motor

Next, we finalized the brackets for the two motors, making sure the dimensions were all correct.

Finalized bracket for the DC Motor

Finalized bracket for the Servo Motor

Finally, we purchased bubble solution with a bubble wand, which we are going to use for the machine. We made a model of the bubble wand, shown below:

Model of Bubble Wand (purchased)

Second Team Meeting

All members were present at the meeting. We wrote the Arduino code and created a few example parts.

Here is the code we are going to use for the bubble machine:



Next, we designed the mount for the servo motor:

We want to reduce the height of the mount and simplify it to use less material.

Next, we designed the dish that we will use for the bubble juice:

 This part may also be changed once we find out if it needs to be more wide or shallow.

The last part we designed this week is a bracket for the DC Motor:

Concept

The idea for our project was inspired by the "Bubblesteen Bubble Machine" as shown below:

We hope to use a servo motor to dip the wand into the bubble juice, and then a DC motor to spin the fan blades, causing bubbles! We would like the mechanism to be activated using a pushbutton, and use an LED to indicate that bubbles should be being produced.

Parts List:
Bubble wand (store-bought or 3D printed)
Moveable arm to control bubble wand (laser cut or 3D printed)
Base for bubble wand / arm / servo motor (laser-cut?)
Fan blades (store-bought or 3D printed)
Fan mount  (laser-cut)
Base to attach fan mount and bubble want mount  (laser cut)

we also need to make sure that the DC motor has enough torque to spin the fan blades (look into gear-boxes etc.)
