Arduino Chromatic Clock, with Steampunk style

Arduino Chromatic Clock, with Steampunk  style

Need a unique gift for Christmas? ...
This watch unlike normal, uses colors instead of numbers, yes! you read right ....
After maaany years of reading color codes of resistors and capacitors I believe that it could be used for something a little more original.

This watch uses a module RTC  DS3231  of high stability and accuracy, and a moisture module DTH22 . Includes a LDR light sensor to adjust the brightness of the LEDs WS2812 responsible for the 'digits'.
The digits are expressed by colors and most correspond to the colors used in electronics to indicate the values except 0, which goes from black to weak white, so that it can see in the dark, and 8 passes from gray to cyan because gray is not possible

    0-Weak white
    1-Brown
    2-Red
    3-Orange
    4-Yellow
    5-Green
    6-Blue
    7-Purple
    8-Cyan
    9-White

NOTE: Although the photos and video seem that colors are a bit 'washed', it is a problem of the cameras, due to the difference in brightness between the digits and the environment. In reality the colors are saturated and perfectly distinguishable (well ...colorblind would have a little sketchy ...)

Features:
 - Time / minutes / seconds
 - Date / Month / Year
 - Tempreature/ RH / Heat index.

Make cycles, time - date - moisture, indicated by three bulbs, and 'sleep' after about 30 minutes.
He wakes up when 'detects' a IR of a command code: TV, radio, HI-FI ... or when there is a sudden change in brightness (in my case is ta in the lounge and is thought to be active when someone is watching TV, listening to music, or to switch on the light).
There is a LED under the plate that changes color producing a decorative effect ..

The structure is made of copper tube 12 mm, easy to find at any hardware / plumbing / DIY store, a few elbows and 'T's of the same caliber, some elbows from 1/2 "to 12 mm for welding and some junctions the same caliber. to cut the pipe I used a very cheap special tool that cuts the tube effortlessly (mini version).
The base is a pine wood, cut and milled varnished.
The digits are formed by LEDs WS2812 (of which are mounted on a small plate with capacitor), and XL marbles (20 mm). ..

The circuit

Schema.

This is the BOM:

1. Arduino (pro-mini, uno, nano, ...)
2. 7 leds WS2812 (6 actually are sufficient, one is 'decorative')
3. RTC board DS3231 (o DS1307)
4. Moisture sensor DHT22 (ó DHT11)
5. IR sensor38Khz
6.  LDR
7. ULN2003
8. 4 bulbs (6V)
9. Some resistors and capacitors ...
10. A USB charger (which I use as power supply)

Well this is the list of components, all easy to locate on the Internet.
I have not used PCB, but a breadboard:
