Lou – Infinity Mirror Table

This tutorial will teach you how to make an Infinity Mirror Table. This table will light up objects that are placed on it, giving you a beautiful backdrop for your objects, but also force you to clean everything up before you leave the room, because the light will only goes off ones there is nothing left on the table. A one-way plexiglass mirror reflects LEDs into a two-sided plexiglass mirror, giving off the illusion of an infinite tunnel of lights.

Wiring the Arduino
The NeoPixel LEDs are composed of 3 different outputs: Ground, 5V and Din. The NeoPixels LEDs need to be connected to Pin 6 on the Arduino board and the Piezo has to be connected to Analog 2. You will need to download files to get your library to work on the following website (this website will also explain you how to change the colors of the LEDs and more): https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library
The Piezo convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tones and alerts AND you can use it as a sensor, to detect fast movements like knocks. In simple terms, the vibration of an object being set on the table will trigger the Piezo sensor, a switch capable of detecting fast movements. Once the piezo is set off, the NeoPixel Digital RGB LED strip will turn white lights.

Building the Table
This next paragraph is will describe how I built my circular table. However, this technique can work with tables of any dimension and shape.
To create the tabletop I created a double-lipped ring. I used the CNC router to cut one 22-3/8” diameter ring, and two 22” diameter rings with 22-3/8” lips. Then I glued them together with wood glue and clamps. The lips are for the plexiglass mirrors to sit apart from each other and to create space in between for the LED strip.
The base of the table is made up of two 22-3/8” diameter wood circles and eight 2”x4”x13-3/4” PLY wood slats. The slats are sandwiched between the two wood circles, creating a solid structure to support the tabletop.

Lou’s Three Final Ideas

Invisible table menu
This table is for a restaurant. It is a table that at first looks totally normal, but once we sit and are waiting for the menus, the waitress will just press a button (that would be placed on the side of the table – or under it) and a light inside the table will light up and will show the menu that would also be hidden in the table.

Low “illusion” table
This low “illusion” table will look very simple at first. It will have a cylindrical shape, with a mirror on top of it and inside it. Inside the cylinder there will be LEDs that light up whenever we drop something on the mirror. Then we will have the impression that there’s a hole in the floor (because of the LEDs reflected in the mirror inside of the table).

Welcome sculpture
This sculpture will be a transparent ‘welcome’ panel that lights up every time you/someone enter/s your place. It will be placed on the wall in front of the door. ‘Welcome’ would be written with LEDs and all the ‘electrical stuff’ will be seen, because I like to see how many strings we have used and how everything is connected to each other.

Lou’s TAXI gloves

 

 

This glove is is a special taxi glove. It is composed of two conductive threads: one on the top of the middle finger, on the inside of the hand and one on the top of the index finger, on the back of the hand. When we connect the two conductive parts, ‘TAXI’ will light up in the palm of our hand, so that taxis see us more easily during winter when it’s freezing and dark.

Lou’s Three Ideas For Innovative Switches

Three ideas for innovative switches:

1. Walrus marionette
I want to add some conductive thread inside the walrus’s mouth so that when we close it, the conductive thread will connect and the eyes and tusks will light up.

2. Mittens with straps
These mittens will have straps that are illuminated when we close the conductive hook and loop tape together. The straps will have different colors, depending on where you strap them.

3. TAXI gloves
On these gloves there is a conductive thread on the top of the middle finger (on the inside of the hand) and on the top of the index finger (on the back of the hand). When we connect the two conductive parts, ‘TAXI’ will light up in the palm of our hand, so that taxis see us more easily during winter when it’s freezing and dark.

Lou – Mr. Walrus

Mr. Walrus

First I wanted to create bear mittens where the mouth would be illuminated with red lights when we open and close the bear’s mouth. But unfortunately, it is not possible to do it with a momentary switch. The light would only have been on while we were pressing on the switch, and that means, when the bear’s mouth is closed. And there was nothing more than illuminated mittens.
So I decided to create a marionette that will teach children something more: Morse code.
‘Morse’ has two different meanings in French: There is the code and also the animal (called walrus in english).
The marionette’s eyes (2 blue LEDS) will light up when we close the walrus’s mouth. These LEDS are wired up to a momentary switch and a battery.

Lou’s Night Lamps

  1. Gloves (Bear Gloves)
    I always wear mittens during winter. And: Winter is coming!
    So I wanted to create bear mittens where the mouth would be illuminated with red light when we would open and close the bear’s mouth.

  1. Reading Lamp
    I can’t go to bed and fall asleep. I always need to read or watch a series. And the problem with ceiling lamps or table night lamps are that once you almost falling asleep, you have to wake up and turn the light off. So I thought of creating a small doll, with the light as a head and the fabric body filled with polystyrene microbeads, so that it can take any position and be placed anywhere.

  1. Blanket
    I have always a blanket at home for watching television, reading a book, etc. And I thought it would be nice to have one that I designed and created.
