Project:	Wake Lamp (I)
Description:	Ceiling lamp based on what a resting rowing shell would look like from under water.
Skillset(s) :	3D Modelling • 3D Printing • Arduino • Laser Cutting • Shape Extraction
Project Type(s) :	Personal Project

I reviewed videos and photos to understand what this would actually look like. Then I 3D modelled the belly of a rowing shell and the blades of some oars and 3D printed them. I Laser cut (or rather engraved) the shapes of the waves around the shell and the oars out of a sheet of translucent acrylic. I glued the 3d printed parts on the bottom of the acrylic sheet. Then I built the body of the lamp, and installed RGB LEDs against a randomly reflective background out of crushed up aluminum foil. I then programmed an Arduino to create the appearance of the change of colour and flickering under water in the LEDs.

File:Wake Lamp.mp4, but the camera actually processes against the subtle changes in lighting, so not a very good representation.

-=== Arduino ===
-* [https://www.adafruit.com/products/1315 Arduino Micro w/o headers] - $24.95
-==== Arduino Size ====
-.7" x 1.9" x 0.4" (17.77mm x 49.52mm x 11.59mm)
-=== LEDs ===
-==== white ====
-* 60 LEDs/m, max 1.2A/m at full brightness
-* 1200mA / 60 LEDs = 20mA / LED
-* installed length for 99 LEDs --> 1980mA at full brightness
-** suspect this is why things are getting hot
-==== colour LED WS2812B ====
-* 34 LEDs installed
-* somewhere I have a reference of 60mA/each --> 2040mA
-** well, what the hell was I thinking?
-* datasheet: https://www.adafruit.com/datasheets/WS2811.pdf
-* bought on ebay [http://www.ebay.com/itm/50Pcs-WS2812B-LED-With-Heatsink-10mm-3mm-DC5V-5050-SMD-RGB-WS2811-IC-Built-in-/281270793101?pt=US_Lighting_Parts_and_Accessories&hash=item417d0bb38d]
-=== Power Supply ===
-* need 2A for each 5V (colour), 12V (white)
-* 0.5A, so 60W
