Ritual Intervention

OVERVIEW

A satisfying useless machine that squeezes toothpaste onto your toothbrush at the push of a button. This 1 week project allowed me to mix my talents and interests and work out problems quickly. I’ve always loved the idea of intricate machines doing simple jobs.

Brief

The brief for this project was to design a ritual intervention as a physical component using Arduino. The brief asked to focus on people rather than technology and to use both hardware and software that can sense and respond to what humans physically do.

Nothing worse when you’re running late getting ready and your friends are waiting for you outside and you still need to brush your teeth. A machine which puts toothpaste on your toothbrush for you by the push of a button is needed.

SKETCHING

How will it look? But most importantly how will it work? Sketching out what elements are needed and thoughts on how it will be assembled before heading into the workshop.

Making

Using Arduino project 09: Motorised pinwheel I could concentrate on the mechanism that will follow the spin. This was the most intricate part of the build; I need to figure out how many cogs I needed in a chain to which would slow down the rollers which the toothpaste will sit in.

  1. I laser cut out an array of cog sizes and tested them however the motor was still to fast. I needed to get a motor of 1000 RPM down to 8RPM without loosing force.

  2. As I wanted to make all aspects of this machine I milled the two rollers and connecter for the cogs out of an aluminium rod.

  3. I then moved on to 3D model cogs to be 3D printed to sit on two rollers and allow the rollers to rotate against each other which will squeeze the tube of toothpaste and pull it backwards.

  4. Finding a 24 RPM motor half way through the build changed this project for the better. It allowed me to take away two sets of cogs and made the connection from motor to rollers a lot smoother.

  5. It was then time to laser cut and form holdings for the assembly of all elements to fit together and run smoothly.

If I had more time I would have connected a wifi shield to the Arduino and have the machine work through an application on my phone instead of a physical button.

2. Milling aluminium process. Accuracy was extremely important to fit the diameter of 3D printed cogs.
