DC Motor: Actuation Assignment 1
Using the servo we were encouraged to make a device that moved forward. I felt inspired by how a knee functions so I made one with the erector set parts offered last lab.
To make the travel more effective I mounted the servo on a pair of wheels, the front was a leg that functions as a support while the "leg" has a rubber band foot to create better grip as the servo actuates the leg assembly.

Arduino
Cables
Description:
I created a pinwheel attached with varying frame pictures. The pictures look as if they are in motion as the motor spins. The concept is similar to a flip book.

Balsa Wood
Cardboard
Tape
Arbuino board

I decided to move away from more serious topics with this assignment and, instead, create a 'pet' by recycling a strange piece of packaging I've been wanting to use in a project for a while. I thought this assignment would be the perfect opportunity to finally give this odd item a life of it's own.
Description
I tried making a simple mobile for this project. The spin of the motor seemed weak, so I wanted to make something with as little weight as possible.

I intended to use a hacked kill-a-watt meter as it was done here and use the current and voltage readings from it to make the DC motor react to changes in these variables.
Description
I designed a baby mobiles-like toy for cats. The motor is connected to a stick, which has two toys on each side. User can control the speed with a potentiometer. The implementation was not hard. But to get it to work required some additional efforts. Since there were too many parts, I had to put them together so I can hold the breadboards, batteries, potentiometer, and motor in one hand. The 'user' testing was also pretty difficult. Our cat - Mimi - is a little old and very lazy. She usually doesn't bat any toys even right besides her.
Description
I made a Duck Hunt game. Two potentiometers detects the virtual gun's orientation. The gun gives the user vibration feedback to simulate a machine gun.

- My product concept is to develop a handy milk frother consists of DC motor, twisted wire, bolt. It is easy to use, easy to carry on, and easy to clean up. You can simply turn on the button and adjust speed of twisted wire by using a potentiometer. The motor seems to be fast enough to stir milk and make form in a good condition for latte or cappuccino.
Description
Created a automatic Phenakistoscope. The precursor to the Zeotrope, a Phenakistoscope is just a disk with holes cut in it. Looking through the slits in the disk, with a mirror in place let you see a animation of the pictures on the disk.
The disk I found online is of a galloping horse, clearly influenced by Muybridge's work in photography. http://www.cutoutfoldup.com/patterns/1136_us.pdf
A potentiometer controls the speed at which the disk spins, while wooden dowel gives it some stability.
Code is from the example.
