Final Project – First Draft

Hi everyone! I’m making an alarm that lets you know when you forget to either lock the door or close it, as my roommates always forget to do it and I come home to an open door at 1 am or find our door wide open as I leave in the morning. This has given me so many micro heart attacks!

The alarm will be trigger by two prompts the first one when there’s no contact between the door and frame, the second one when it’s closed but not locked. The idea is it will make a sound and show light, also in case they are too distracted or something, it will send either a text message, give them call with a pre-recorded message or block their phone until they close and lock the door. I haven’t figured out what will be more efficient to get their attention.

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.

Shoe Box Plush Light

The shoe box is for working professionals who get home really late or for party lovers who are always out. The product could be placed by the entrance door or in the bedroom, so when they finally get home they can have a diffuse light that would guide them in the dark and help them take their shoes without turning on the lights and waking everyone up.

Process

Before my actual prototype, I did some mockups on cardboard to get the dimensions right and figure out how to project the shadow.I started by creating the pattern of the box and then repeating the same pattern with a few changes to saw them together and create a thicker wall that would give a little bit of support to my collapsing fabric. I also added a foamboard base to create a place for the battery pack to sit and stay hidden.

I also added a foamboard base to create a place for the battery pack to sit and stay hidden.

Then I solder my 8  LEDs and wires together just as shown on my circuit diagram and inserted my battery pack in its place and redirected all my LEDs to the lateral face of the box. Then I started sawing the pattern together, I made sure to leave a little-unsawed part to pass my wires and LEDs through (So they could remain hidden and protected and that I can redirect them in case something was wrong).

While passing my wires through I pull a little too hard on them and rip my circuit apart, so half on my circuit got disconnected 😦  So I had to make some changes, because I didn’t want to remove rest of my circuit from the already sawed box. Then I saw the missing spots to keep everything inside and started sawing the finishing touches.

Circuit Diagram

My circuit change a little from the one I had last week, I decided to have all my LED’s on the same size, which I don’t think was my brightest idea because the shadow footprints are hard to get projected and more light would have been helpful.

Shoe Box – Plush Nightlight

Pattern (first one): After making this one I realized my original measurements were not working because the handle was too short and the sides were not rigid enough, I either have to put another material like wire or cardboard or make a second wall with fabric and then saw a division to create de angle to shift the direction of light towards the ground, the second wall would also serve as the battery and wires hiding space. So my new pattern should look something like the image below.

Prototype: After making the prototype I noticed the footprints were not as defined as I thought they would look, so I have to make another footprint hole on the back overlap and have it perfectly match with the original hole or change my fabric to one that diffuses light and cast shadows in a better way. Also, I made a tiny prototype which I think made it more difficult to get the dimensions and shadows right, however, it gave me an idea of how to add structure and how to play with shadows to make my light diffusion appear clearer.

Circuit Diagram: I realized I don’t need bigger LEDs it could work with same size LEDs, I just have to make sure to pick the right fabric.
