Bibble: A Smart Desk Lamp for Roommates

untitledbarni

The Bibble is a desk light designed to let your loved ones know where you are (or at least where you’re scheduled to be). The lantern can sit on their desk, softly glowing a particular colour, depending on whether you are at home, school/work, or out. It uses IFTTT integration to search for keywords in your Google Calendar, triggering your NeoPixels to change colour.

Idea Proposal: Spoiled Food Detector

Hi Becky!

I haven’t fully fleshed out the idea yet, but I want to make a little shelf attachment for my fridge door, that can read if my vegetables are still edible.

I’ve been looking at a combination of pH sensors and ethylene sensors (rather unsuccessfully).

The pH sensor is quite expensive (https://www.dfrobot.com/index.php?route=product/product&product_id=1025), so I will look at making my own, following these instructions: http://overskill.alexshu.com/cheap-ph-meter-hack-for-arduino/

The ethylene sensor seems to be rather expensive/inaccessible as well: http://www.winsen-sensor.com/products/4-series-electrochemical-toxic-gas-sensor/me3-c2h4.html

So now I’m looking at this methane sensor: https://www.sparkfun.com/products/9404, as decaying food will also emit methane.

EDIT 1:

Sketch of vegetable freshness monitor, using pH sensor:

proposal-sketches-01The box would sit inside a shelf in my fridge door. The sensor would read the pH level of the water that the leafy green vegetables are sitting in (+ other veggies that sit in water), and translate it to a freshness level out of four bars: the fewer bars that are lit up, the less fresh the veggie is!

 

 

 

EDIT 2:

I was considering that the methane sensor wouldn’t make a lot of sense in combination with veggies, but perhaps I could translate it to work with spoiled meat:

proposal-sketches-02

So the idea is generally the same (in the sketch I am playing with the idea of red-yellow-green lights instead of bars), except that the meat sits in separate, closed compartments such that the air can saturate with methane.

 

 

I will update this post throughout the day with more details as I come across them—just wanted to make sure that I got it up on time!

Useless Machine Take Two!

This was my useless(ish) machine:

It wasn’t actually useless.

I had some issues with the hot glue, which seems to have disconnected my soldering.

So it was actually powered by this push button.

But now!

It works!

This is my code:
 

#include <Servo.h> 

Servo myservo;  // create servo object to control a servo 
int photoval = 0;
int photo = 0;


void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);       // open the serial port at 9600 bps: 
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object 
  myservo.write(90); // set servo to mid-point

}

void loop() {
  
  photoval = analogRead(photo);
  Serial.print("photoval after reading = ");
  Serial.println(photoval);
  photoval = map(photoval, 0, 900, 0, 255);
  Serial.print("photoval after mapping = ");
  Serial.println(photoval);
    if (photoval < 240)
    {
  myservo.write(20);                  // rotate counterclockwise full speed
  delay(910); 
  myservo.write(88);                  // stop
  delay(2000);
    }
  // put your main code here, to run repeatedly:

}

Kit the Fox Spirit

Kit is a baby fox spirit that wanders through forested areas along the northern border between the U.S. and Canada.

He likes to switch between glowing blue and white, depending on his mood and how cold he’s feeling! Because he’s so young, he often forgets to pace his gliding, and is often dizzy as a result. This is why he has a permanently cross-eyed look.

Process: I chose to put together a series circuit and wrap it around a frame. Within the coils, the plushy is stuffed regularly, such that it can still be soft. The core (as pictured below right), which helped keep the body soft yet improved upon light that was too focused. I ended up having to add both ping pong balls and tulle to make the light diffuse in the way that I was hoping.

Plushie Prototype Part 1: Chibi Totoro

My initial plushie concept was to create a tanuki ghost. I tested the opacity of a soft flannel and found that light penetrated quite easily, so I used it to create the body. I used black and white felt for the eyes.

Unfortunately I neglected to take a photo of the wiring, and after much shuffling, 3 of the 4 LEDs went out (which is why the light is concentrated in one corner). I’d like to use stronger wires and maybe sew pockets onto the inside of my plushie to prevent this for my second iteration!

To personalize the plushie in my next version, I want to create larger, more structured ears, and add feet to the figure. I liked the ghostly-ness of the green LEDs, so would like to change my circuitry to have 3 tiers of colours: green around the feet, blue above, and white from the centre of the body, upwards.

Char the Burnt Log

inclass-plush

This is Char the Burnt Log. He used to be a branch, until some humans decided to go camping near his home. They didn’t buy enough firewood so they decided to tear him off his family’s tree. The humans put him in the fire, which was rather uncomfortable, so he decided to make a lot of smoke. The humans quickly took him out and now he lives on the gravel camping lot staring at other logs burning in the firepit.

Plushie Ideas!

Hi! My 3 plushie ideas are:

  1. Totoro – either the teeth or the little triangles on his belly would light up
  2. Chibi Totoro – Chibi Totoro is a white tanuki spirit, so I was imagining his whole body (other than his eyes) would light up with a soft white glow
  3. Ghost – I liked the idea of a soft white glow, so another option would be a simple ghost
  4. Quatchi Head – One of the mascots for the Vancouver 2010 Olympics! I would have his earmuffs glow (This one might be difficult because he’s furry)
