This LED lamp is in a way a continuation of my previous project "Fiber Optic and LEDs - a Wall Decoration", I think a natural one, I wanted to make something simpler, easier to do, that would be available to many of you. The "mechanical" parts of the lamp are 3D printed, the electronic part is simple and the plastic optical fiber is eye catching. The shape of the lamp is inspired by Helder Santos' project "Square LED Lamp" and the arrangement of the optical fibers is very similar to that of my project mentioned above. I will show you in this instructable how easy it is to make this LED lamp.

When a part from company A is assembled together with a part from company B to form a final product, these component parts must have the same surface roughness. If they don't, the ability to form a seal will be compromised. In this situatoin, it is a major problem if companies A and B manage surface roughness using different standards. The International Organization of Standardization (ISO) regulates standards in order to define surface roughness.

I made the rest of the connections according to the electronic schematics and then I mounted the lamp support and fixed it with a lot of hot glue, I fixed the touch button also with hot glue (not before mounting the push pin) and I fixed the Arduino Pro Mini module in the place provided by the support.

Surface roughness is defined as the shorter frequency of real surfaces relative to the troughs. If you look at machined parts, you will notice that their surfaces embody a complex shape made of a series of peaks and troughs of varying heights, depths, and spacing. Surface roughness is greatly affected by the microscopic asperity of the surface of each part.

I started with the 3D printing of the components, it takes quite a long time so in the meantime I was able to make the connections between the pieces of LED strip. It is good to check the correct operation of the LEDs before mounting the soldered pieces as in step3 of the project "Fiber Optic and LEDs - a Wall Decoration" (I just changed the value DATA PIN to 5 and NUM_LEDS to 32 in the test code).

After finishing the printing of the frame, the hardest part followed: ) fitting and fixing the four pieces of 8 LEDs each in the channels of the lamp frame. I loosened the protective plastic of the self-adhesive layer of the LEDstrip and for the best and most precise fixation I also used a few fiber optic ends inserted through the side holes. Then I slowly untied the protective layer and by pressing the strip to the frame, I fixed it. You can see the operation more clearly in the photos above.

Differences in surface roughness obviously lead to visual differences, however, they also have an effect on a variety of other characteristics. Examples include: the amount of wear, the ability to form a seal when a part makes contact with another surface, and the thickness of the paint needed to coat a part. This is why it is necessary to quantify surface roughness, that is, the microscopic asperity of surfaces.

The final step in building the lamp was to upload the program to the Arduino micro controller. I used an USB to Serial module with the FT232RL chip connected as you can see in the photos above. Of course you can upload the code with other USB to Serial adapters. There are a lot of howto's online about programming the Arduino Pro Mini.

I put the lamp on the bedside table, I have been using it for a few days and I really like it. I am very satisfied with how the construction succeeded. However, maybe I will make some changes in the future…

Consider the surfaces of machined parts that you see all around you. These surfaces come in a wide variety of surfaces, from shiny and smooth to rough and matte. These outer differences are because of the different surface roughness of each part.

The program is essentially an adaptation of the codes from FastLED Breath for the breath effect, from palettes with button control for the different color palettes and the code from DemoReel100 with button for effects. For putting the Arduino Pro Mini to sleep, with a double click, I was inspired by this article. Also, at this moment (double click) the current operating mode is saved but also the settings from each operating mode.

For example in color palette mode I would make the brightness lower or choose color palettes with lower brightness. I would add a few more effects, I really liked the noise effect in my "Fiber Optic and LEDs - a Wall Decoration" project, I'm thinking of adding it to the effects mode. I could also power the LED strip through a MOSFET transistor as I did in my "Safety Armband" project and thus greatly reduce the idle consumption of the lamp. Now if I turn it off with a double click, the lamp consumes about 30 mA and in operation I measured a maximum of 400 mA.

This operation was followed by inserting in the side holes some pieces of plastic optical fiber. I cut the pieces as perpendicular as possible using the same template as in the "Fiber Optic and LEDs - a Wall Decoration" project. 8 pieces of fiber, so a total of 16 pieces, of different lengths join the pairs of holes that are at the same distance from the sides of the lamp frame, as in the photos above.

The lamp works in three main modes that can be selected by double-clicking on the push button: solid color mode (and with the breath effect), palette mode and effects mode. With a simple click in solid color mode you can choose different colors (9 colors) also with the breath effect, in palette mode you can choose several color palettes that are taken from PaletteKnife for FastLED and in effect mode…some effects :)

There are countless methods that can be used to quantify microscopic asperity. Some examples include finding the level difference between the highest and lowest points within a 1 mm 0.04" square area or finding the difference between the average of 5 high points and the average of 5 low points on a straight line 2mm 0.08" in length. However, if standards are determined in this sort of arbitrary fashion, inconsistencies may occur.
