Cell Structure Lamp

thingiverse

Simple lamp that changes color :-) The dimensions are 60x60x90mm printed in white PLA in this case. For the inside, I designed two diffusers: one is printed in "spiral outer contour mode" and the other is a flat plate that sits on top of the LED's and Arduino. The pictures show the flat one; I used it because the spiral one warped and couldn't be printed with just one wall layer. Maybe someone else can do it! So, I made the flat one using two layers, making the diffuser 0.4mm thick. This makes the light spread more and prevents it from shining directly into your eyes. If it's still too strong, you can make the diffuser slightly thicker, like three layers for instance. It's also possible to use a paper or thin material diffuser. The light source is an Arduino Nano and six NeoPixels. This is probably the easiest and cheapest way to make a light source right now because I'm using the Arduino as a power source for the LED's too. These NeoPixel LED's are run by code on the Arduino, but you can read all about it here: https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library-use. Adafruit made some very easy-to-use library's to run these NeoPixel LED's, so I just installed their library's and modified one of their examples. Now the LED's change color over time! You can do a lot more than that too. If you don't want to research all of that, you can use the Arduino sketch I included with the files; I also added the Adafruit library that is needed to compile this sketch. For the connections from Arduino to the NeoPixels, see the "schematic" at the picture tab. The Power Source is a 5V phone charger (at least 1A). I printed it with a 0.4mm nozzle, resolution 0.2mm, three top/bottom&wall layers, and 15% infill. Do you have any questions? Feel free to ask! Do you think I made a mistake or forgot something?
