Kallisti Posted March 28, 2014 Share Posted March 28, 2014 Something like that. I used to build Meccano fairground rides with LEDs in them and often the easiest way to make the return connection was through the Meccano itself, then you only needed one wire I guess its not so simple when it not all metal Link to comment Share on other sites More sharing options...
roma847 Posted March 28, 2014 Author Share Posted March 28, 2014 This is stunning work. I'm seriously contemplating the card model you're basing this off, as it's just so much better than the comparative "blob" that comes with the kit. Keep up the good work Thanks Mike for your nice words, the show must go on, and also the lighting chapter, stay tuned. Link to comment Share on other sites More sharing options...

roma847 Posted April 1, 2014 Author Share Posted April 1, 2014 Hello folks, we stay a little longer in lighting, because it's just so beautiful tricky. Since I still had to glue the centering tubes in the shortened lampshades, which was doable again only under the microscope. And since the tubes have some clearance in the shielding sleeves, the superglue-gel (Pattex) proved when gluing but suitable as better than the liquid superglue (UHU) I had used before. Thus, there are not only the "classical" lampshapes on the MLP, the almost entirely on the pad (FSS/RSS) are installed, but also some lamps without a pronounced screen, as can be seen in this picture. These are, inter alia, the two lamps above the LOX Valve Skid, below the right TSM. Source: retrospaceimages.com (STS-6) And also the hazard warning lights (beacons) have a similar shape with a glass cover, Source: NASA which is why I modified these lamps something. In addition I have used the same ferrules, but not expanded, but only reduced accordingly with the Dremel cutting disc. These are the lampshades right in the picture, next to the tiny tubes that were now still glued, what looks like when finished. For the hazard warning lights I have now picked out a few more suitable transparent tube beads for the glass cover and trial strung, what ever does not look bad. The pods I can possibly cut something else and I'm still looking out for something shorter beads from my stuff, then the shape has come out quite well, I think. And as a test I now have threaded a red LED (0401) with the thin copper wires (0.1 mm), and low and behold, the tiny LED fit even along through the bead through, what the solution is somewhat simplified. And then I only had to connect the LED to my current bank, and the signal red lit up. And for the two lamps under the blast shield I will also find a solution, but the Sunny White LEDs (0603) to be used there, unfortunately are slightly larger than the tiny red LEDs and therefore require a slightly different solution. That's it again for today. Link to comment Share on other sites More sharing options...

roma847 Posted April 3, 2014 Author Share Posted April 3, 2014 @batcode: Thanks for your nice words, stay tuned and only have fun. @Kallisti: You are wondering, but I don't know if you ever have glued such tiny parts with superglue in the range of less than 1 mm? If you see these pictures, you can imagine possibly that you no longer can do it cleanly without a magnifying glass. This small tube, which is to be glued into the screen is only 0.9 mm wide, and only on this tiny area you are allowed to apply superglue around, otherwise sticking your tube to the needle and in the lampshade and you have built a nice composite. Or look at this tiny LED that needs to be glued in place with the flat side toward the top in the screen, that you can not control with naked eyes, unless you have eagle eyes, but you're not an eagle. BTW, if you have better experiences, let me know, I'm curious. Link to comment Share on other sites More sharing options...

roma847 Posted April 17, 2014 Author Share Posted April 17, 2014 Hello folks, let's go on!  By looking for the hazard warning lights in age-old image collections from the 80s so I've got further researched and studied this time the lighting on the Access arms of the Tower (OAA, OVA, HVA), but to do sometime soon in more detail.  Source: retrospaceimages.com (STS-6)  Today I want to show a quick update to the lamps whose mass production is now underway. These are again the normal lampshades for the lamps on the MLP Access Platforms left in the picture from the expanded ferrules (3 mm), as well as the unexpanded screens (2,4 mm) for the hazard warning lights, which are in the small dish. For this I had already found the matching glass beads, in which one just could fit the red LEDs (0401).   Then I still had looked for matching glass beads for the lamps 11, 12 and 17 with a slightly larger hole,   and found actually beads with a diameter of 2.2 mm in which the slightly larger Sunny White LEDs (0603) would fit longitudinally. Here one of these LEDs is even threaded in such a bead.   Here you can now see two variants, the top for a lamp with a expanded screen, and the bottom one with unexpanded screen, which actually both could be used, because these minimal differences can hardly be distinguished under the Blast Shields anyway.   Then briefly to the planned reconstruction of the Current Bank, what already had indicated as a result of extensive brightness tests by reducing the power intensity of the LEDs in the direction of 0.5 mA. In addition I have now begun to replace the fixed resistors (47 Ω) by variable Mini Trimmers (1 kΩ), because the light effect should look even more realistic.   And here the first Mini trimmer has been soldered.   And to finish for today two tests with a Sunny White LED with minimum setting of the trimmer (> 6 mA), i.e. maximum brightness,   and here at maximum trimmer setting (0,5 mA) and reduced brightness.   And with these parameters, the final current bank for the whole Launch Pad is now designed that offers even better performance than the previous one, which I will present soon.  Next, the remaining fixed resistors to be replaced by the trimmer. 4 Link to comment Share on other sites More sharing options...

roma847 Posted April 17, 2014 Author Share Posted April 17, 2014 Thanks for the nice compliment. Â And I've still soldered the trimmers, finally does come the Easter Bunny. Â And so the current bank now looks with the eight trimmers. Â Â Because the place for soldering was pretty tight, I have omitted to insulating sleeving. Â For my part I'm fully satisfied, all beginnings are difficult ... And the most important thing is that all circuits have passed the function test with flying colors. Â So now the existing eight circuits, each with up to 12 LEDs in series let set with the same or different brightness and off separately. At the pad all the lights were finally not always switched on simultaneously and shined with the same brightness as one could see. In this sense, all of you a Happy Easter!

roma847 Posted April 24, 2014 Author Share Posted April 24, 2014 Hi there, Â so after hopefully all Easter eggs were found of you, it will go on again. Â Coming soon the prepared lampshades should be painted before the LEDs can be glued in. Unclear to me was previously only how to hold tiny creatures (3 mm). After some thought, I came up with the following solution that should work. Â Â Since the lampshades are painted gray from the outside, they should stand upright, but also can not fly off when airbrush. Therefore, I have stung pins through a Balsa strip and placed ferrules on the tops, and then the shades were threaded, and ready is the Painting Support (PS). Â Here 24 slots are first prepared and stocked, the PS may also be extended. Â Â To avoid that light comes out upwards, I have the screens painted up black. If then the gray paint comes over it, which then should actually suffice, if not, still a splash of color comes on top after threading the LEDs. Â Â Consequently, then the first series can go for painting. Â Then I again experimented with the special lamps (11,12,17) and further tested two variants. In addition I wanted the Sunny White (0603) longitudinally thread in the larger glass tube, which just fits so. Â Â And two of these couples I have now threaded each in an unexpanded screen (right) and into an expanded screen (center). On the left is then compared with a standard lamp (3 mm) with cross inlaid LED, as used for all other lamps on the pad. Â Â Here with > 6 mA, which is very brightly, as expected, Â Â here with 3 mA, somewhat more subdued, Â Â and here with 0,5 mA, with relatively moderate light. Â Â In the right variant you have the unimpeded light exit of the LED, which is literally blinding and not recommended.The middle variant seems to me quite reasonable and would differ so from the other lamps. Â So far again for today. Link to comment Share on other sites More sharing options...
roma847 Posted April 27, 2014 Author Share Posted April 27, 2014 Hello folks,  I can not shake the stage fright, and therefore I again thought about the red flashing warning lights,  Source: NASA  for which I had procured the red LEDs (0401).  For these lampshades I want to use the unexpanded ferrules. For the glass body I had initially thought of a transparent bead. But since the hazard warning lights under the outer glass body have a red insert, a reddish bead would be better suited what I wanted to try and compare, let's go the whole hog.   Here you can see both versions at full brightness (> 6 mA), which makes color virtually no difference. Only the brightness with the transparent bead appears to be somewhat stronger, but this is insignificant.   And here are the test results at the moderate brightness (0.5 mA), where the effect appears in the image paler than in reality.   Here I have trial basis attached both beads in shades with a tiny superglue droplet, so that the warning light as such is already purely externally visible, which I like better.   Now I have threaded the LEDs in both lamps,   and tested the optical effect as described above:  > 6 mA:   0,5 mA:   How was almost expect to see the effects are similar. Therefore, I will probably decide to red glass beads.  So the stressful testing with different lamp types and brightness settings should have an end but now.  In the next days I will now make an inventory of the lamps on the RSS so that the design for the final current bank can be rendered more precisely. The lighting of the FSS was relatively clear and will probably mean 8 lamps per floor, what ever gives approx. 100 lamps.   Added to this are the lamps on the Access Arms that I need to check again.  Source: retrospaceimages.com (STS-6)  While the tower is relatively clear, the RSS still gives me quite a headache, but that will be somehow estimated in a first approximation. Here, I will first try get along with images of the STS-6. After my previous knowledge not only the former lamp shapes appeared significantly different than in the later missions, the number of lamps at the time was significantly greater than at the end of the program.  That's it for today, see you soon. 1 Link to comment Share on other sites More sharing options...
RichO Posted May 5, 2014 Share Posted May 5, 2014 HI MANFRED, The build seems to be going great!! The mass production of the lights is going to be so much fun!! (LOL) I do really like the look of the red beads for the warnning lights, good job there. I'm also so glad I could give you fits about the introduction of the lighting. Just think of how incredibly impressive this will be all lit up with these mini lights. I'm not that far from waking up my own lighting dept (again) and putting them back to work. You know. All looks very cool dude, keep building!! Link to comment Share on other sites More sharing options...
roma847 Posted May 7, 2014 Author Share Posted May 7, 2014 Thanks Rich for your encouraging words.  The mass production of the lamps is one thing, on the other hand it's also important to know where all the lamps sit. Hello folks,  therefore the time has come, as already announced, I've begun in the last few days with getting things straight concerning the RSS lamps and started a gradual inventory. However, this turns out to be quite stressful and one hand is almost like looking for needles in a haystack.   And on the other hand, the image analysis provides such a lot of lamps, so I slowly but surely get an uncanny feeling, when I think of the laying of the LEDs ...  First, I have long brooded over how I could best do, where I realized more and more, that this can not be done in a breath, but that it only gradually progressing and lots of patience needed.  For such an analysis one needs high-resolution photos and if possible from all sides and from different perspectives. Of these, although I have collected gradually a lot, but the detail photos are only half the battle. For now begin the grueling hard work of screening and comparing the more or less easily recognizable lamps, in which one can become dizzy.  More difficult is the fact that there are not particularly many usable shots of the STS-6. Therefore, I am also avoided to the other missions from before the STS-6 and have been looking back up to STS-1, of which there are some good shots.  And by and by then sharpens the view and you can see the arrangement of the lamps then better. In order to start with a count, I've then initially colored circled the lamps but deliberately not numbered, because the numbers are still can change, the more one's eyes bend and lamps recognizes that previously were not clearly visible. And when evaluating different pictures and views have to be extremely careful that one does not count lamps twice. Anyway, this is not just a balm for the eyes.  I don't want to put you on the rack but longer, and just show you the first overview shots, then the tricky undertaking is certainly clearer.  This is the front of the RSS, and alone on this view I have found about 50 lamps, the transition from FSS to RSS are not even considered.  Source: retrospaceimages.com (STS-6)  Well, start has been made, even though it was only a small taste first, the next steps will follow soon.

roma847 Posted May 8, 2014 Author Share Posted May 8, 2014 Hello together, Â these are the lamp locations on the back of the RSS at STS-6. Â BTW, as you can see here, there was at first initially only the small PCR Anteroom, as it were, the vestibule to enter the highly sensitive Payload changeout room (PCR), which was later extended to the right thick pipe. But I must orient myself to the former images. Â Source: retrospaceimages.com (STS-6) Â And these are also at least 20 or 21 lamps when the green circled lamp top right is counted together, but it's a part of my separate counting of the stairwell on the side that I've counted separately for clarity, what you can see on this picture. Â Source: NASA Â Incidentally, this is a photo montage of two sub-images, which I have greatly enlarged me for marking and counting of the lamps (1x click), otherwise you would have been alone with the holding apart too much difficulty. Â All lamps are hard to see in this overview without magnification, so I'm counting of course also of images with different perspectives, where you can see the details better. But you get in the detection of these tiny details already on visual limits to what you must consider. Â Here is such a picture from one of the last missions, where you can specifically recognize the lamps in the external stairwell clearly, especially at high resolution (2x click). Â Source: NASA Â So, the "red" lamps are already included in the count of the front, now the 12 "green" and the 6 "yellow" lamps in the two stairwells can be added. As a result from these three views now have 91 lamps (53+20+12+6) on the RSS, but without the lamps on the transitions of the FSS to RSS, which have not yet been counted. Â To this end, here are a looking ahead to another nice STS-1 picture, on which one can recognize these lamps well at high resolution. Â Source: NASA Â And in this way I live more laborious as the squirrel and layaway from lamp to lamp ... Â In this sense, the count continues - The lighting show must go on!

roma847 Posted May 8, 2014 Author Share Posted May 8, 2014 Thanks Kallisti for your honest compliment, I fully understand you.  But fun times aside, this lighting programme could slowly but surely grow to a Never ending story if the designed current bank would not show me the limits. And the today's state of my planning all inclusive are about 400 lamps.  What that means in detail, will be quantified only after my complete inventory of the pad lighting, but I will pull through in any case and about their house number I myself am very curious.  But so much is revealed before, in any case, should the lighting of Lightning Masts at Level 265 (80.75 m) including,  Source: NASA  for which four strong spotlights were installed at the foot of the mast, as one can see in this nice picture of the STS-1.  Source: NASA  But honestly, dear friends of the sun, this all so far is just gray theory, whether if I actually can implement all in practice on the model, will have only still show ...  But I'll try it anyway, and you should all strong fingers crossed for me!  The acid test will ever be the upcoming MLP lighting, and if that works the way I imagine it, I can already say more.  Now you can say I'm a dreamer, but I'm not the only one ...  Nothing is impossible! Therefore stay tuned, wait and see! 2 Link to comment Share on other sites More sharing options...
