    The Sleeper

    Wow.... I am tired! I have spent this past weekend making custom 2 and 3 LED "series" circuits for all of my pre-cut acrylics... and I must say, it has been a learning experience!

    I still have to glue the LED's into the acrylic, and then cover the soldered LED legs that go from one LED to the next (brush on electrical tape is what I am planning... any other suggestions?), but from the test pieces that I lit, I think it is going to look good!

    Very excited about this... as I do not like to solder (*gasp*... a modder that does not like to solder??!?! ), and this is the most intensive part of the soldering on the build!! Get this out of the way, and I can start concerning myself with other parts! Pics will be coming in a few days after I get the test lighting done with the completed pieces.

    There are a few pieces that I have not lit yet, as I am still trying to figure out how... but I have some ideas. We'll see how that progresses!

    Ok, so this is not all of the pieces (obviously), but it will give you a good look into what I am having to do with each piece!

    Continuing with the famous piece from the previous post, I set to lighting it up. I did this by placing the LED's into the 5mm holes that were pre-cut, and then using a pair of needle nose pliers to bend the legs so that they would intersect. Remember, each LED has a positive (longer) and negative (shorter) leg. When runing the LED's in series, you have to keep those polarities in mind. Think like magnets.... positive to negative. So, I would lay out the LEDs in their holes, and bend and cut the legs so that I had positive to negative layout, and a clean path to solder on:




    Test lighting




    What would it look like on the panel? I mocked it up. I did not do a "long time exposure" on the camera, and the patio door was letting light into the breakfast room, so the photo effect is off, but you get the idea... it's gonna work!!!



    This one was a close fit, but I got it to work! I thought it was going to be my most difficult set.. nope!


    A couple pictures showing how I start on the LED's and make the initial bends and clip the leg lengths to make it fit the path:



    From the above two pics, this is what that LED set looks like out of the acrylic:


    One of the bigger pieces:



    Ok, this was my "Pièce de résistance" of this escapade!
    Problem: I Had a piece of acrylic that was cut. It was a small piece of the logo, looked somewhat similar to the triangle that is in the "Star Trek" logo. Issue was, when we designed it for a hole, we put a 5mm LED facing one way... well, how in the hell am I going to make light shoot out both ends of that piece? I need to have two opposite facing light sources *inside* the space of a 5mm LED hole! Hehehehe... uh, yeah.... right!

    Solution: God had my back when I ordered my LED's way back when. The place I bought from (www.unique-leds.com) had some LEDs that I had never seen before! 1.8mm LEDs!!!! So, I bought some at the time to get a look at them and see how they worked! Fast forward to this solder party .... I took two, and designed a series circuit. Issue was that the cathode and anode legs had to be trimmed VERY short in order to allow for the LED's to fit back to back. This makes for dangerous soldering as you dont want too much heat in that proximity to the diode of the LED, as it could damage it...
    Also of note, the positive and negative legs that were for the power and ground wires, those had to be bent nearly right at the base iof the LED (dangerous). Lots of things were stacked against making this work... but I'll be damned if I didn't pull it off!!!




    Lights up *bright*!!!!

    I ended up making the initial leg bends, and then sticking those through styrofoam to get the LED's in the right proximity to each other. I then trimmed the legs to be soldered so that there was not a lot of leg material hanging off all over the place. Took a couple of snips, removing a tiny bit of material each time with the micro-snips... but eventually I had them set right where i wanted them.

    Then my precision tip on my soldering iron snapped off!!! ARGH!!! All I had as a replacement was a spade tip... suck it up Craig, and make this work. I did, and it did!! I then took a small diameter piece of heat shrink and I covered one of the legs, ran it all the way up to the base of the LED, to make sure the legs did not ground out against each other.

    Test fit in the back of the acrylic:

    I got tired of wonderin.... and just got to doin!

    Had a pleasant temperature outside, nothing f-f--ff-ridgid.... Mucking around with acrylic, I certainly did not cold acrylic being hit with hot glue.... and potentially messing something up... so I had to wait for the temps to come up a bit. Call me paranoid...


    I hot glued in all of my LED's tonight, and test lit the largest piece...



    This is showing you how all of the pieces will fit to the panel. The lines feed through the panel to the LED's




    Obviously not a final placement, there is no adhesive on the back side, but you get the idea.



    What good would it be without a light shot?



    I fed all of the other pieces through their respective holes and found out 2 things....
    1) I forgot to drill holes for 2 pieces (shown on the panel with their cables)
    and
    2) I missed 2 of the shaped pieces for LED insertion. So I Have 2 more pieces that I have to get lit. Should not be a problem though....


    It is coming along though!

    this is so looking fantastic.. hope you added rubber spacers to as many bolts an screws as possible to help keep the noise and the shock down for the internal components.. be a shame to get it into the car and have parts fall off.

    So, I pulled out my drilling template from the previous holes, and finished drilling the missing shape holes, and then also got to thinking about the ASUS logo, and "how in the hell" am I going to saturate that logo with light?




    Multiple directional LED's is the only way I can come up with right now:


    Of the 2 pieces I forgot to light previously, thos one was cut for a 3mm LED, and I needed a bit more space to make the dual 1.8mm LED's fit properly.... so I bored it out with a grinder bit using my Craftsman rotary tool.


    This was the other shape that I forgot to light up....


    My 1.8mm LED's soldered back to back in series! (getting good at this now...)



    Insert... light... and say "Ahhhhhhh!"







    I also bought some liquid electrical tape to insulate the legs of the LED's against the metal panel.


    Here is the example piece before application.


    And after application.





    Some of the pieces I clamped to the bottom of the shelf to make the liquid tape sit on top of the metal LED legs, instead or settling and flattening out.





    Here, I took all of the shape pieces (since I finished drilling out the holes), and I placed them. To hold them near their positions, I used clear masking tape. This was more for me to see how everything eas laying out, and if I needed to make some correctivce cuts. There are a few pieces that are needing a shift and a tweak to get placed right, but for the most part, they came out very well!






    And... the "Go big or go home" moment of the night, I tied all of my 12v legs and grounds toghether in the most ghetto hack of a wiring job... but it was only to see if I had broken anything and if the concept that I had of power supply was going to work.... and gloriusly, it worked just as I had hoped!



    Remember my picture of what I wanted?


    Awfully damn close!!!

    Wow that's a lot of tedious work on the led's. I don't have that kind of patience.

    This is looking really cool. I'll keep an eye on it.

    So.... how do you know when I'm liking the weather and I have time to work on the mod???


    When I start hangin stuff from the gutters on my house, that's when!

    I spent most of the day wandering around Dallas looking at components for a circuit board. And it hit me on asle 7 of Altex Electronics in Carrollton... "You can work on the frame in parallel with the electrical stuff! *DUH!*

    So, tonight, I broke out the Self etching primer, and my flat black enamel and went to town!

    The victims, they are defenseless!





    First round of self etching primer:


    After two rounds of self etching primer:



    I followed them up with a 3rd coat of Primer Sealer, as there was a spot on the motherboard tray that I had used a permanent marker, and I knew from experience that those would bleed through if I did not put some sealer on them.... worked like a champ!




    Don't see those red marks do you? Say it with me folks... "Primer Sealer" ... that is the answer!



    Then it becomes time to pour on the flat black with vengeance Anything that was light gray on the inside of the case, is now Flat black!!











    And I owe all of these parts to one can of the good stuff.... I have 2 more parts to paint, and some touch-ups to do on these parts, but this paint is tha' bomb diggty!



    I have a clear, satin topcoat that I will be using to make this paint more durable, but that is not on yet.
