I have decided to redesign and update my initial plush ice cream night light. This time I would like it to have a more refined design, as well as more function. You may find my outline here:

Hey guys, for my final project, I’m going to make a lamp installed in the library that will discourage people from talking loudly by utilizing their sense of guilt.

How?

Check it out 😀

Hello Everyone!

How many people have ignored a text message, by accident (or on purpose!) in the last week? If you are me, the answer is more than one…

Keeping close to all your people can be tough, especially when you have many important people in your life. Social circle keeps all your loved ones in one place, and tells you when you are slacking on the conversation. Nobody likes to be a the person who ignores their friends, and now, you don’t have to be that person!

Check out my (in progress) tutorial on how to build this magical device that builds thriving relationships!

For my final project my goal is to create a clock that can display up to 100 years of time past a certain date. It does this through six different dials all powered through independent stepper motors connected to an Arduino reading a real time clock module (thanks Becky!).

I am imagining that a clock like this could be used to mark the exact amount of time since an important event (birth of a child, anniversary, a person starting sobriety), to help mark the occasion exactly. Depending on how the building and coding goes, the resetting of the clock via a button every time it is pressed may be a feature for V2.0.

Below can be found my drawings regarding possible form, as well as my link to the outline and tools/materials list.

Hi all,

My final project is a speculative project.
Its purpose is to raise awareness around how many and how often people die from shootings in this country.
You can find my document here.

This is my code, which needs a lot more work, since it is the hardest part of the project:

 
		
/* -------------------------------------------------------------------------
ShootingsArtefact -- an artefact that reacts to the number of deaths by shooting in the US
using the the Adafruit HUZZAH ESP8266 WiFi microcontroller (can also work on other ESP8266 boards)
with numbers provided by http://www.gunviolencearchive.org/. LED on pin 15 shows status:

Steady on = One-time initialization
Fast flicker = Connecting to network, polling data
Slow blink = Symptoms predicted in forecast (24-48 hrs)
Blip ea. 4 sec = Symptoms not in forecast (sleeping)

----------------------------------------------------------------------------
Configure the code below with your WiFi credentials. Then visit
http://www.gunviolencearchive.org/ and look up the number you wish to display.
Copy the URL into the appropriate spot in the code below.
When changing the number to be displayed, you will need to dig through the page's HTML
source to find a string that uniquely identifies the condition sought, while
avoiding false positives. See additional notes later in the code.
----------------------------------------------------------------------------*/

#include 

#define LED_PIN 13 // LED+ is connected here
#define POLL_INTERVAL (15 * 60) // Time between server queries (seconds)
#define FAIL_INTERVAL 30 // If error, time before reconnect (seconds)
#define READ_TIMEOUT 10000L // Client read timeout, milliseconds

// This structure is used during string-matching operations. Only the
// 'string' element is initialized here; other elements are initialized
// or modified as needed in multiFind(). This code is NOT AVR-friendly;
// PROGMEM strings are not used, it's assumed this will be running on
// an ESP8266 (or ported to other non-AVR board that just normally puts
// const strings in program memory instead of RAM).

const char * const string;

Hey guys, for my final project I’m making a device that plays music counter-intuitive to the weather outside. If it’s bright outside, it plays slow music. When it’s overcast, it plays upbeat music. Here’s the google docs link that contains my rough outline:

Hi all,

For my final project, I’m exploring how to make a touch-activated xylophone that plays nature sounds (tentative name: Xylophorest). It uses various components by Bare Conductive, a small studio based outside of London (thanks Becky for the recommendation!).

You can read my rough project outline here.

1.- Lock Door Alarm: Inspired by my roommates, who never close or lock the door when they come home. The idea is to build an alarm that would turn a light when the door is unlocked and send either an email or ideally lock their phones until they close and lock the door. (I have no idea how you would do the second one)

2.- Lazy-eye patch timer: My niece has a lazy eye and has to wear a patch for an hour each day. She allways forgets to either time it or wear it. The idea is to have a button, and once she presses it the timer would start, the button would the release a patch and a card to play a sort of Tetris – lego game that I can remember what is called. The game helps improve her 3D vision and keep her mind of the fact that she is wearing a patch. once the timer is of she should have finished the game.

3. Plant nanny: I recently bought a plant, because I missed having a garden, the problem is I always neglect my plants. The idea is to have a light, and a reminder sent throughout the day to help me of either water it, take it to het some sun or talk to it.
