The Tickle-Me Desk Lamp
Inspired by the Mimosa pudica, or shy plant, this lamp will feature petals that fold and close when not in use in order to safely and easily carry it around. Ideally, if I am able to use some kind of touch or motion sensor, then it will also be able to open and close its petals when touched, like the plant. The effect will be a lamp that is more of a companion, with feelings and emotions, than an inanimate source of light.
Scientific plant name: Mimosa pudica
Description: This plant is a creeping annual or perennial herb often grown for its curiosity value. The compound leaves fold inward and droop when toughed or shaken, to protect them from any predators. It is native to South and Central America. Like mentioned before, this plant is known for its rapid plant movement, meaning it undergoes changes in leaf orientation, called “sleep” or nyctinastic movement. The foliage closes at night, or when aggravated, and opens in the daytime. The response to any kind of disturbance, known as seismonastic movement, happens because certain cells lose turgor pressure, or the force applied to the cell walls by water. Once disturbed, parts of the stem are stimulated to release chemicals including potassium which force water out of the cell vacuoles, resulting in the closing of the leaflets and collapse of the leaf petiole.
1. Continue to work on Scratch exercises daily
2. Fabricate your initial lighting fixture model with LEDs(Due: next Wed. midnight). Bring your fabricated model without LEDs on Tue. class. I will explain how to wire LEDs and how to solder wires.
2.1 Using Rhino 3D (following the class demo)
2.2 Using a laser cutter or a 3D printer. (no hand model)
2.3 Make one model per each team.
2.4 Make a base for your model . 12 x 12 x 0.5 inches. MDF (you can buy one at the digital lab). Etch frame lines, your name, course name, project name, and scale using a laser cutter >> I will bring a sample next Tue. class.
2.5 Scale is 1 inch = 4 inch (1/4 scale model)
2.6 Draw a plan, 2 sections, a rendering (following the class demo)
2.7 Install two LED diodes on your model.
I am interested in designing a lighting fixture that is multi-functional. Additionally, one that is attractive in a room, for more reasons than just its physical and aesthetic qualities. I feel that all rooms have a feature or product that instantly brings life to it when a person sees it. This lighting fixture should do the same, but for reasons OTHER than because it provides light.
For my lighting design, I will base its conception around the structure of the jellyfish, scientifically known as a “cnidaria” The jellyfish is a free swimming marine animal found in every single ocean in the world, although partial to salt water. Jellyfish are frequently located in coastal zones. Not only are they found in all oceans but they are found in both deep sea waters, and in surface level areas and shores. Jellyfish have been recorded to have avoided extinction and are known to be one of the longest living marine animals, having been around over 500 million years.
These organisms are a bell-shaped creature and they vary greatly in size, they can range from one millimeter in diameter to as large as 2 meters in diameter and can weigh up to 4 pounds.
Jellyfish begin spawning once they have reached adult-size. Spawning occurs daily, with sunlight. Jellyfish usually live about 2 to 6 months, with most of their life span ending once they have begun spawning. Adult jellyfish release both eggs and sperm into the water and unprotected eggs are fertilized and develop into organisms.
Jellyfish have a “mouth” located at the bottom of its “bell-shaped” envelope that is used for both eating and releasing. (See diagram for how food is sucked in through the mouth). Jellyfish feed on crustaceans, plankton, fish eggs, and even smaller jellyfish.
The following diagrams highlight the structure of the jellyfish makeup as well as its swimming and eating process.
As you can see in the structural makeup of the jellyfish, an outer “umbrella” supports and protects the organism, with an inter layer (gastro-dermis) that is a cavity holding all the internal parts of the jellyfish, which is also where food is ingested. Between those two layers is “jelly” scientifically called “mesoglea”. My light structure will be a vase (the outer umbrella) with an internal cavity (gastro-dermis) to house the LED lighting. Between the vase and the lighting will be space for soil, water and most importantly flowers, which is parallel to the “jelly” between the two layers of the jellyfish. Being that this will be dual purpose, some may see it as a vase with flowers first that happens to have a light; others may first see a light with flowers surrounding it. To each his own. The sketches, elevations and plan below explain the makeup of the lighting fixture.
General Name: Hawaiian Bobtail Squid
Scientific Name: Euprymma Scolopes
Dimensions: The average male adult is about 20-30mm (0.79-1.18in)
Weight: The average male adult barely reaches 3 grams
Geographic Location: Surrounding Hawaiian Islands
Climate: Tropical, saltwater or marine. They are found in warm, shallow coastal waters 2-4 cm deep. This is unusual because most sepiolid squids reside in very deep water
Food Chain: “sit and wait” predator
Life Cycle: Development=Metamorphosis. Lifespan=2-3 months in the wild, 3-5 months in captivity
Breeding Speed: There are no specific seasonal breeding intervals for this squid. Clutch sizes vary between 50-200 eggs. It takes an average 30 minutes to lay each clutch of eggs. The number of clutches each female lays varies greatly. After females are finished laying eggs, they cover them with sand and then depart, leaving the offspring to fend for themselves.
