 Fiber optic LED decor lamp Fiber optic LED decoration light In this article, we will look at a very interesting homemade product – a fiber optic LED lamp. On the site where the master posted his work, more than 10 people have already unsubscribed that they made such lamps, about 100 people commented on it. Of course, some of the parts for this lamp are 3D printed, but not everyone has one. But it is not necessary to do everything exactly like the author, some home-builders used wood or a metal profile to make the case.
Let's watch a short demo video (I advise you to watch it from about 1 min 40 sec)
Tools and materials: -Fiber-optic cable 3 mm diameter;
-Address LEDs WS2812 60 LEDs per meter;
-Microcontroller Arduino Mini Pro 5V; -Button 12x12x7.3 mm; -Cable with connector; -Power supply 5V/1A; -3D-printer; -Connecting wires; -Glue gun; -Heat shrink tube;

First you need to print the body parts. Files for printing can be downloaded below.

For the convenience of installation, the wizard gives a diagram.

It is recommended to check the LEDs before assembling the elements.
After finishing the frame printing, the most difficult part is installation and fixation of four parts of 8 LEDs each in the lamp frame channels.

If there are 32 LEDs, then the optical fiber is 16 sections. They connect pairs of holes that are equidistant from the sides of the lamp frame.
Fiber-optic LED decoration light Next made the rest of the connections in accordance with the electronic circuit. I installed the lamp support and fixed it with hot melt glue. Installed the button and the Arduino Pro Mini module.

The final step in creating the lamp was loading the program into the Arduino microcontroller. The wizard used a USB to Serial module with an FT232RL chip connected, but any convenient method of downloading the code can be used.
The source code of the program is on github, you can download it here.
The lamp has three main modes that can be selected by double-clicking the button: solid color mode, palette mode, and effects mode. With a simple click in solid color mode you can select different colors (9 colors), in palette mode you can select multiple color palettes taken from PaletteKnife for http://fastled.io/tools/paletteknife/and in effects mode some effects. < br> The program is essentially an adaptation of FastLED Breath codes for breath effect, button-controlled palettes for different color palettes and a DemoReel100 code with a button for effects.
By double-clicking the lamp, you can put it into sleep mode while saving the current settings.
We used external FastLED and ArduinoMultiButton libraries and internal sleep.h and EEPROM.h included in Arduino. .
