Kuan: watch dog (working in progress)

Watch dog is a device that can gurd your life in multiple ways. That’s how it works, firstly, you put something on the disc , and whenever anyone trying to take the thing away, it automaticly turn on the watch dog and starting shooting paper balls at that person.img_1073

So for start , i want to use a photo resister as the input device, and i found its hard to use it in the dark , and it’s really delicate.

So i changed it in to a level switch. which is easier to handel .

For the out put part, i use two leds, one toy motor, one toy luncher kit, mutiple gears, one servo motor and multiple resisters.

So, this is what i get so far!

Update: Manako’s final project

Project Description:
The project consists of curves that hang from a frame that change their shapes as they interact with the audience.  Various ropes (or wires or threads) will hang from the top of a frame/arch, creating different curves. Conductive thread is wrapped around these ropes, so that the ropes will function as capacitive sensors.  Once a rope is touched, it will turn on the motor that is placed on top of the frame and pulls the rope upward.
The effect is like playing a visual string instrument.
Material Exploration:
Below artifacts were hung from a drying rack to assess their materiality.
dsc_0132
  • fishing string
  • beading string wire
  • ball chain
  • laundry hanging string
  • yarn
  • nylon rope
  • 2 flower arrangement wires
  • jewelry chain
  • frame hanging wire
Ball chains made the best curves and they were conductive, making it compatible with capacitive sensoring system.
Motor Exploration:

Below motors were tested.

  • 5V DC motor
  • 12V Stepper Motor
  • Rotating Servo

DC motor doesn’t have sufficient torque to rotate the spool and pull the chain up.  The servo has good torque and it’s easy to use because of the wheels that attach to its shaft, but it makes an awful, high-pitched sound.  The stepper motor has the torque needed without the annoying sound of servos.

In-Class Peer Writing Review

In class today we’ll do a peer review writing exercise to improve your Instructables drafts. If you have not done so already, please start out by composing your Instructables draft and paste the link in this Google Spreadsheet we’ll use to organize the activity. I will then paste your draft into a google doc that folks can make suggestions on.

If you have written your draft, please review your classmates’ drafts. Do this by reading over the draft Instructable, then marking up your suggestions in the associated google doc using the “suggesting” feature (not directly editing the doc):

screen-shot-2016-11-29-at-8-31-58-am

Feel free to raise questions, correct grammar/typos, suggest ideas to clarify the instructions, etc. Once you have reviewed a draft, put your name under one of the “reviewed by” columns in the spreadsheet, and move on to another draft.

If you run out of drafts to review, please write your shooting script for your project’s video, then check back for newly added drafts. After your shooting script is written, you may also use the rest of class to work on your project, and we’ll regroup for the last 20 minutes.

Week 12 Homework – Prototype & Write Instructable Draft

For homework over Thanksgiving, you should continue building a prototype circuit for your project, and developing its final form and code. Many of you have two parallel development tasks– don’t put off any unknown part of your project! The sooner you uncover the unknown parts of your project, the sooner the finish line will be in sight. Please feel free to schedule a 1-1 with me if you need one, or email with any type of questions.

For class next time, please bring a working prototype of your project and any pieces of the form you may have developed. Please also complete a first draft of your project Instructable (text and linked URLs is the bare minimum, please also include any images that are also ready). Do not publish your draft, but rather send a link to the preview to me by email by 8pm the night before class. I have composed a sample draft to help guide you.

Wifi Power Strip

I wanted to find a way to make my apartment smart without investing a lot of money. Thats why I have decided to make a wifi power strip that I can control over my phone. I can plug in any device to the plug and turn it on and off form my cellphone!

So I cut the connection between every plug to make them individual. There is one for the USB connectors to the left, you can see a blue and red cable coming out and then the plugs, I cut the metal strip that connected them to make them individual plugs. Then, I connect each plug to 1 of the relays including the usb connectors and I plug the Relay to the wifi controller and Vuala, I have my smart power strip!

HOW TO BUILD YOUR OWN POWER STRIP.

Step 1

Get all of the materials in the list.

  1. Power Strip
  2. 4 channel relay
  3. Wifi arduino controller

Step 2 – Dismantel the power strip.

Step 3 – Cut the metal gold strip between the plugs to separate the conection in order to control them independently.

Step 4

  1. Connect 1 side to all positive, in this case blue and the other side negative. Then plug in the positives to the positives in the 4 channel relay and the negatives in the negatives.

Finally plug the ground into one of the 4 channel since the ground is shared by all them and connect the 4 channels to the wifi controller.

Now you have to figure out the code!

Proposal: Draw your mood

Imagine we have a twitter mood light, connected to a mechanical arm which draws. I want to make this amalgamation of Arduino projects which detects and ‘senses’ the world mood and represents it via a drawing. After much deliberation and research, I feel that the twitter algorithm has changed(even though I have found a few, wherein this is possible) and it is not possible to tap into its data.

Another possible iteration is to make a device which captures emotions using the press of a button and at the end of the day draws an image based on the prominent emotion of that day. Example: There are a few buttons installed at the PoD, people press(Happiness, Anger,Fear and more), at the end of the day the device captures the most dominant ‘mood’ and draws( I think I have to manually put in the image I want it to draw, though.) a painting relating to the most dominant emotion.

This can also be captured using the Vortolight method which uses a service like IFTTT to reflect colours based on what people tweet about. Essentially instead of changing colour, I would like to ‘move’ the drawing handle in a way which relates to a tweet.

Example: I am angry today #red. This makes the vortolight go red, in the same manner, the robot will draw a little something over a prompt by the tweet.

I looked at a few drawing robots and this seemed the most viable/accurate in terms of using a MECHANIX kit and servos(besides regular electronics) whereas the twitter part is mostly coding and web services(and a wifi module which should not be as expensive, however, the one used in some cases is).

Looking forward to starting with this after your feedback!
