Good people, has long wanted to do this and yesterday was the day.
On this occasion I hope I bring something that's surprising.
What did I do? I decorated my desk with lights neo blue, red and green. How was? look ...: D

Did you like ? I hope so.
is something I took an afternoon, but for me it was worth it and it was something I wanted to do.
Maybe not the big deal, but I like it and I feel that orgullozo.
Now, as I did? Well, easy. It is not difficult or dangerous. Although we are dealing with electricity, it is dangerous if we take all possible precautions.
Materials:
A power supply 12 V
a cable outlet plug
A lid of the box where they come from hard drives or similar.
A picture of the size of the top, next to polifoam Motherboar or similar. Insulator (called "cutapercha" or "watapercha as I say: lol: and here)
A cutting pliers or a welding torch cautil
aluminum welding
A Phillips screwdriver or flat, depending on what kind of screws used
Also:
Cable
Paper or double-sided tape to secure the cable contact to our office
A switch or single switch or integrated light (like the one I used)
Most importantly
Lights neon color who wish, of those who use the modified cars on the inside you know which ones?. Acuerdence that are 12 volts.

Well, explain the electronics.
First we build our circuit. The concept is to have is how do we connect several lights to the source, we must connect in parallel. Why not in series? What happens is that in series the first light will act as resistance and therefore the others do not recive the proper voltage. This does not happen in parallel, the current is divided equally for each. That's why we connected in series.
I used a switch or switch with integrated light. You can buy one without a light, simple two 'legs' (where the wires are connected;)).
Here the circuit diagram:

Call FEM is our source voltage of 12 volts. Source EMF electromotive means.
no force actually executed ... well, on another occasion I explained that the FEM from the physical point of view, electricity. : P: P: P: P
see, it is connected to the positive and negative terminals of the switch. As my swith is light, has three legs: a PEF + and the other two are FEM -. Why? That one leg (bottom) is for light, the center leg is where you connect the lamps. What happens is that when you close the circuit (turn on the switch), the leg of the center is a bridge. The current passes through the leg and another (-). A paw for the light switch and the other for lamps. The positive leg is too light, a - y + (else never light up). When you set the swith, the current passes into the center leg and distributed to the rest of the circuit. That is why eneciende light switch and lamps. Am I clear? They must know this in order to assemble the switch connections.
If in such case, if swith no light, you only have 2 legs. Simple, connect positive to positive and negative to negative.
How plugs into paraleo? All lamps positive connection, should conectarce to the positive terminal of the swith, just the negative. Thus all light up. Do you understand?
Questions? Ask with confidence.
Since we have our armed circuit as we have in the figure, we must build the power supply (FEM). I say: lol: Before you do anything, we set the source to test the circuit hehehe The thing is I wanted to explain as a weapon and that the circuit.
We took our cable and cut it around here:
http://i169.photobucket.com/albums/u225/Zero_boy17/DSC01587.jpg
In our source, must have ports or connectors that say +12 V,-12V, GND, the ground symbol, -5 to +5 V, etc.. We provide current to the source, obviously. So, cut the cable as shown peeling a little tip to get the copper wire and give the finger several enrozcadas so that the wire is not 'espelucado' I mean, it is not in filaments, but Picked yes?

Where we connect this cable that provides the 120 - 125 Volts to the EMF? Usually, they are always the last two from the opposite end at 12 V.
As seen in the figure, the source said AC-N and AC-L. Here we connect. How? that's not important, can connect any pair in either:
http://i169.photobucket.com/albums/u225/Zero_boy17/DSC01588.jpg
After being introduced, tighten the screws so that the ports are set to "Tamos?
Now do the same for the cable that supplies the 12 V lights. Obviously we have to get a cable for 12 V lamps.
to them easier, buy red and black cable. There are wires that are black with red and that will be confused.
In my source, appears first, 12 V, -5 V and GND. GND is the famous Ground. Later is also land that is not the same.
Well, the GND is the negative 12 V (-12 V). We grabbed our positive cable, red and adjust course in the harbor of 12 V. The negative lead on the GND (third place).
Now, to ride that is our pc, we can not have around anywhere. So I opted for the same wood screw into the cabinet. Nothing to preocuparce. Does not affect the wood.

As we must protect this part, so the sheet of polifoam. We cut a box the size of the circuit in FEM and place it in the plastic lid. Then mount the FEM at the top with the polifoam.
To catch it, we must pierce the cover to pass the screws. EMF has and must have holes for screws in the corners.

Well, what else is carpentry. Place, the lamps in the parts of your furniture you want to illuminate. The wiring is very important. Depending on where you put the switch, so it must be the wiring. I tell the source that I have behind the green light. The switch is a green light next to the keyboard. I recommend you throw 12 volt power cable to the switch, as it is in the schematic diagram: + in the corresponding leg and the - in question. In the scheme put 1,, 2 and 3. Apply if it is + or -. The 1 is the refusal of the FEM. The 2 is negative for lamps and 3 is the positova of the FEM. OJO here positovos connect the lamps to switch the positive and negative to the center leg if you buy a switch like mine. If you buy a simple, straightforward, positive leg all positive lamps and negatively with all the negatives of the lamps. We have to be a circuit where the 12 volts going to the switch, and where all lamps are connected to swith. I emphasize: positive and negative positovo swith with switfh negative, if two legs, the simple. If you have light, three legs, you know how.
Now, I recommend soldering the wires on the switch 12 V, which come from the FEM and remove a cable from the positive leg and the refusal not to swith be a lack of focus on the switch just "understood?
after everything is already assembled and tested, is a matter of taste. If you connect the FEM to the outlet, not light, do not worry. Turn the connector (which connects to the plug, not the wires of the EMF) and connect. Should light. But revices and ask someone Yeah?
Well, a great pleasure to find leito everything and I hope you found this job very much liked, and of course, be encouraged. If I did not know anything about electricity (I know I investigated), what you can do. If you have questions, inquire in with someone who knows. If you do not understand any of this, ask what will gladly clarify.
Greetings guys!
