PC VU-Meter Kit Installation
This mod came about one night when I was on the net scoping out mod sites and thought that my case could use some illumination. Somehow, I don't quite remember, but I ended up at the PC VU-Meter Kit web site. After checking out this site completely I decided this kit is worth a try. The case I will be using for this mod is an Antec Gemstone series case translucent green. I did not take pictures of every single step, but I have pics of most the major points of the install. If after reading this you have any questions drop me an email and I will be willing to lend a hand if I can.

Materials: Quantity: Amount:
PC VU-Meter Kit (1) $30.00 + s&h
LED  Mounting Clips (20) $2.40 @ $0.12 each + s&h
Audio Cable (1) $2.00 at Radio Shack
  Total: $34.40 + any s&h charges

The first thing to do is to decide where to put the lights. My case has an two-tone arc on the front.  I wasn't sure whether to run them up the sides in a straight line or run them along the arc. I decided for the latter. This is the more complicated install choice but I think it will make for a unique look. The difficulty lies in the measurements. The first issue is the spacing. I wanted to start each channel from the center of the box and end them close to the top of the green area.
I needed to get a center line of the lights that follows the existing arc of the panel. This took some ingenuity! I taped some standard scotch tape to the panel. This serves 2 purposes: 1) it allows for writing on the case 2) helps keep the drill from sliding when starting a hole. I taped a sliding ruler so the measurement was at 1cm. I am not sure of the technical term for this ruler, maybe a micrometer? I don't know. If you know and feel like emailing me the correct name I will put it in here. Then taped a paper clip to the one end (for a guide to ride against the case) and a pen at the other end. After the jig was complete I ran a mark around the entire length of the arc so there was now a center line for the lights.

Now I needed to figure out the spacing between them. I did not know of any scientific way to do this, so I laid out the mounting clips on the panel to give me an idea of the spacing need to make this look cool. 1.4cm center to center was decided upon.

Very carefully, did I mention very carefully drill out the holes for the LED's. This is what I kept telling myself over and over again. The consequence for a bad drill hole can be catastrophic to the outcome of this mod. The way I did this was to drill a pilot hole first with a small bit. They tend to be easier to control when starting a hole, the drill didn't really "walk" on me as would happen with a bigger bit. This image shows the 20 LED holes all drilled out.
Since this case is translucent which means it is partially transparent, much consideration needed to be given to the wiring behind the lights. I did not want it to look like there was a bowl of spaghetti back there. I separated the ribbon in pairs an put the appropriate pairs through the LED hold that they will be connected to. This helps to get the leads to the right length. I will also be rounding the cable and enclosing it in wire wrap that I picked up at Pep Boys. You don't want to do this too soon because it will be difficult to trace the wires back to see which LED they control.
Almost there! Next I had to decide where to mount the circuit board. Here are some before and after shots. The first picture shows the inside of the case before mounting the board and the second has the board mounted. Note the audio cable on the bottom right of the board. It goes through a hole in the back of the case to a Y connector on the soundcards audio out line. In case you are wondering I have a SoundBlaster MP3+ 5.1 card.
Here it is! The finished product. It looks great in the dark or with the lights on. I think my computer is happier with this kit, don't it look like it is smiling? Looking at these pictures I think the green power LED should be blue! That will be a future mod im sure.
In conclusion, the PC VU-Meter Kit from www.pcmodkits.com was simple and fun to assemble. The circuit board is clearly labeled and the instructions area great. It adds a flair to the case that sets it apart from any standard store bought pc. One of my favorite features of this kit is the fact that you can arrange the LED's in any way you want since they are attached to a ribbon cable and not a circuit board. This ability allows for a wide range of applications and arrangements.
PROS:
- easy to assemble
- reasonable price
- very customizable arrangement of LED's
- Great Look!
CONS:
- LED mounting clips and audio cable sold separately
- high cost if you work at McDonald's
