Locked is a device that measures the distance from a sensor to the locked position of a deadbolt and informs you if your door is secured. It is a cheap and fast way to set up a customizable lock detection system to old doors and buildings.

Motion Sensor, NeoPixel, and Arduino (for Feather Huzzah)
Storyboard

Number Light

The Number Light is a box with lights and a sensor that lets you know when someone is 1 foot away from your door. The number will be cut out of the main box frame. Behind it, will be a completely white compartment to disperse the light from the NeoPixel strip. A white canvas will be glued onto the cutout for smooth light distribution. Behind the LEDs will be the battery holder. The sliding side of the holder will face the back for easy battery change. The whole box will slide on two mountable sliding tracks.

This was a really hard project for me. As you can see from the video, I was not able to use a gemma, so I ended up using the arduino. Below you can see my tinkercad circuit.

Tinkercad Circuit

My Halloween costume will have two circuits. The one viewed above will be sewn onto my cape. The lights will protrude the cape, and I will cap them with spiders. These LEDs will be orange, as the cape is black and purple.

The Gemma circuit is still a work in process. I will have the Gemma sewn onto the mini witch hat. I will use four 3V batteries, in a small carrier, a switch, and an LED strip. I am still working on the code, debating if I should just have the Gemma, or that along with the LED strip. I am excited about this project and how all the colors will come together.

More Halloween

Two circuits

For my Halloween costume I would like to place a NeoPixel Strip, with a Gemma and battery holder/switch inside a small witches hat. That is what the circuit on the left represents.

The circuit on the right will be attached to a cape. I will make 4 holes through the cap to bring the wires from in “inside” out, and I will sew plastic spiders onto them. I hope the LEDs will light up the spiders nicely and they will compliment the cape.

The materials I will be using for this assignment are two batter holders with switches, (I will experiment with using a separate power source and a independent switch), 4 LEDs, 4 resistors, wire, 1 neopixel strip, 1 gemma (if I am able), hot glue, thread, and needle.

Below are three of my ideas for Halloween. The first one from the left is simply a wire crown, with a ping ping ball at the center. The ping pong ball would have an LED in the center, and then wires would run to the backside, where there would be a switch. The second idea is a mask with X’s for eyes. This might be a bit tricky, either by sewing two LED strips onto the mesh fabric, or sewing individual LEDs. The mask would be worn more on my forehead than eyes, since I would probably burn my retina if I had X’s over my eyes. The last one is a string of LED’s with plastic bugs glued onto them.

3 Simple Sketches

To make the above props for costumes I would need: wire, thread, rope, needle, LED strips or individual bulbs, ping pong ball, glue gun, batteries, battery holder with switch.

Droplet

My water droplet nightlight

This nightlight is intended for all ages and groups of people. The following items were used to create this light: 6 blue LEDs, 6 resistors, wire, battery holder with switch, poly fill, mesh fabric, woven light blue fabric, sewing needle and white thread.

Circuit

Making process is as seen above. For better reference, I asked my friend who has sewn her whole life to show me how to use the sewing machine. It was an epic fail. I also tried to use ping pong balls to propagate the light, and that also didn’t work for me. Below please see my friend’s prototype.

Johanna’s prototype (my friend)

Overall it was a lot of the same from the first prototype. I tried to use the ping pong balls, as mentioned, and it just didn’t do me any good. I also noticed that the less poly filling I used, the better it made my product look. I used a mesh fabric to wrap all the lights inside it, and then I inserted the mesh fabric with the lights in the middle of the material. I then lightly filled the rest of the inside with enough poly to hold my pattern shape up, but not too much, so it would not block the light.

Teardrop Nightlight

This nightlight is meant to illuminate any dark bathroom. In the shape of a waterdrop, it complements the bathroom décor. The soft blue led light gets filtered through the soft fabric creating a soft blue light.

This project aims to create ambiance lighting. I plan on adding ping pong balls to help disperse the light. I will also use a sheen or polyester fabric as it will let out more light. In this case, I used cotton, and although the night light had a soft look to it, it seemed quite dim. Furthermore, it did not illuminate all around, and you can clearly see the leds. I plan on using proper polyester filling for this project. Right now, we are looking at recycled soft plastic, crammed in the toy itself. I would like to use more LEDs because it seems like this piece could use more for better lighting. I also made it 6 inches tall, and I believe the top could be a little more tapered off. I used a teardrop pattern which resulted in a more spherical look. In my next prototype I will accentuate the teardrop curves and have a pointy top on one end of the fabric and flat end on the other.

Disassembly Process

I used all strength and force to break down certain plastic parts. Where applicable I used the Phillips head screwdriver. For most of the process I liked using my hands or the flathead screwdriver. The pliers came in handy for removing wires. The knife was necessary when separating the washers and plastic enough to shimmy the flathead screwdriver.

Materials used for disassembly:

  1. Flathead screwdriver
  2. Phillips head screwdriver
  3. Pliers
  4. Knife

There is always one…

I was not able to take this last screw out. I tried to use a small screwdriver, and then the tip of a knife, then the screwdriver again. I ended up stripping the top, at which point I couldn’t remove it without completely breaking that part of the frame.

Design Opinion

I appreciate the light fixture being above the fan. It is practical, and I appreciate how easy it was to disassemble. The dropping on the sides is a nice small design touch that flows with the curvilinear form altogether. Complimentary to the light form are the edges of the fan. The smooth lines run around the whole product almost like a synecdoche of the core function of the product, which is meant to run in smooth infinite loops.
