hof00 Posted December 30, 2018 Author Share #33 Posted December 30, 2018 (edited) Thanks Chap, I'm in the process of re-wiring the LED's I had issues with the resistor N/W so rebuilt this as well. Reliability issues.... I had initially stripped the insulation with Side cutters but lost some of the conductors in the process, a couple of wires disconnected themselves, not a good look as the circuit will be sealed in the Hull. (Since bought some "Auto" Strippers, much better!!) The Mast is going to be interesting to wire, there are three lights on it, one White, two Red, I have a "Plan" I think.... Wiring installed to Deck level, Taper the Mast, slot the Mast to accept "Vero" wire, connect LED's, install.... Also had to remove the last plank that I installed to enable the wire trace.... (Fat fingers/pliers) Not a problem, it's the first cover. Nav. Lights are on the wrong side but an easy fix once I get things working again.... 🙂 Tomorrow is another day!! (Gone with the wind) Cheers....HOF.

hof00 Posted January 8, 2019 Author Share #34 Posted January 8, 2019 (edited) Small update, Built new Resistor N/W, extended majority of LED Cabling, tested and installed Resistor N/W. (Bicycle Lamp Circuit, so to speak.) Tested Mast LED Voltage, 7.2V, enough to satisfactorily run 3 LED's in Parallel. Nice!! (A good "Positive" for the day!!) (The only "Downside" is if the LED's "Go Out...." I will have absolutely no access to the Resistor N/W or Cabling.... I'm pretty comfortable with my wiring, the only cable that I'll have access to is the Power Lead that connects to the Transformer which will exit through the Keel. Anyway, I can now concentrate on getting the first Planking complete.... (3 - 4 Planks per side, Filler, Sand....) Onwards and upwards.... 🙂 I'll post some photos when this is done. All in all, it's not too shabby for a complete tear down and rebuild, thus far. 🙂 Cheers....HOF.

hof00 Posted January 8, 2019 Author Share #35 Posted January 8, 2019 (edited) Hi All, I need some help, if possible.... Thought I had things sorted with LED Illumination,, "Sanson.." Not quite.... I have wired 15 Hi Intensity LED's for this build, (18 eventually with the Mast Head lights.) The LED's are connected in Parallel, 12V supply, 570Ohm, 1/4 Watt Resistor for each LED. LED's power up o.k but he Resistors are getting very, very "Hot" after 30 seconds or so. My fear is that Sanson will "Combust!!" Does anyone have some "Fixit Gems?" for what should be done? What would a probable fix be? The circuit is simple, Positive Rail, 570Ohm Resistor, LED, Common Earth. Rail... (I guess Forward Voltage of the LED is about 2.2 Volts) Any Ideas? My thoughts are that the Circuit is "Gobbling" as much Voltage as it can, maybe 1/4 Watt Resistors are not going to "Cut It." (Not keen on Series Connected LED's, one goes, so do the rest....) If I can't Fix, I'll just have to do without LED's (LED's are a bit of a mission, I think in future Fibre Optics) (I messaged "Tecko" for his take on things also.) Cheers and Regards, HOF..

hof00 Posted January 9, 2019 Author Share #37 Posted January 9, 2019 Here you go.... 12 Volt power supply, 570 Ohm Resistor, maybe 2.2 Volts forward Voltage for the LED's I guess that if I increase the Resistor Wattage, it won't heat as much. All LED's are in Parallel with the +/- Rails, so in essence mimic the below. (My last resort, remove lighting and complete the build.) Any advice, much appreciated. Cheers....HOF.

cog Posted January 9, 2019 Share #38 Posted January 9, 2019 You could just change the resistor, but I wonder if that is the wisest way.

glennreader Posted January 9, 2019 Share #39 Posted January 9, 2019 (edited) There are two equations you need to know to work this out. Ohms law V=IR and the power equation W=VI In your circuit the voltage across the resistor is the voltage of the power supply minus the voltage across the led 12 - 2 = 10V. Therefore to get a value for this resistor rearrange ohms law and substitute the known values. R = V / I = 10 / .03 =333 ohms. The nearest common value you can buy is 330 ohms. To get its power rating W = IV = 0.03 * 10 = 0.3W. So as long as the resistor you use has at least that rating there will be no problems. Up to a point using a higher value resistor will just lower the light output from the led. If you used a variable resistor you could adjust the brightness. The safest way to do this is to put a 330 ohm resistor in series with the variable resistor. That way you cannot turn it down too much and overload the led which will shorten its life. If you used a 560 ohm resistor (570 not readily available) you would only need 1/4 watt. Hope that helps, Glenn Edited January 9, 2019 by glennreader keelhauled, Jonny 007 and cog 3 Quote Current Builds Scottish Maid, V108 Torpedo boat Future Builds Snake (Caldercraft) Previous builds HMS Shark (Sergal), Sirene (Coral), Armed Pinnace (Panart), Etoile Schooner (Billings) Link to comment Share on other sites More sharing options...
cog Posted January 9, 2019 Share #40 Posted January 9, 2019 Glenn, Thanks for explaining. Got a question, since we're at it. This is for a single led, what happens to an array of leds? Just multiply the voltage by the number of leds? Quote Carl "Desperate affairs require desperate measures." Lord Nelson Search and you might find a log ...

hof00 Posted January 9, 2019 Author Share #41 Posted January 9, 2019 Thanks Carl/Glenn, I'll do some further "Experimentation" before sealing any circuitry in the Hull. Much appreciated!! 🙂 Cheers....HOF. keelhauled 1 Quote Completed Builds: A/L Bluenose II A/L Mare Nostrum Sergal/Mantua Cutty Sark A/L Pen Duick A/L Fulgaro Amati/Partworks 1/200 Bismarck A/L Sanson Link to comment Share on other sites More sharing options...
glennreader Posted January 9, 2019 Share #42 Posted January 9, 2019 If I understand your question correctly the answer is yes. But I explain why below in case we are at cross purposes. If you want all of the led's to be on at the same time then wire them in series. Then work out the total voltage across them all. For instance 5 leds is 5*2 = 10V or maybe 11V if it is really 2.2V per junction. With a 12V supply that leaves 1 or 2 volts across the resistor, so the new value will be 33 ohms or 68 ohms. That's the problem when the voltage across the resistor is small compared to the voltage across the led's. You can try and look up the actual voltage in the manufacturers data sheet or if you have a multi-meter you could measure it. For safety go with 68 ohms or alternatively go with 33 ohms and include a variable resistor to set the current to below the manufacturers maximum. The power rating of the required resistor is now much less as the voltage across it is much lower. One advantage in using led's in series, the power is being used in providing light and not heating up a resistor. You should NOT wire led's in parallel using the same resistor. But there is no problem in having say 2 groups in series each with their own resistor. Hope that makes sense. I am trying not to get too technical, which is why I have not given an explanation for not wiring led's in parallel.

hof00 Posted January 10, 2019 Author Share #43 Posted January 10, 2019 (edited) Thanks again Glenn/Carl, Had a look at the typical Forward Voltage and Current of the LED's I purchased, Quite a range of differing values.... (I think I'll go safe with 1 Watt components.) (BTW I think this is the very first time I have asked for assistance, and the assistance/advice was very much forthcoming!! 🙂) I'll keep the Lighting in the Hull, (After testing of course). but will need to redo my Resistor N/W to supply correct Voltage.... 🙁 If things get "Hot" again, I'll remove the Power and go with a build minus lighting. (Don't want a spontaneously combusting model!!) Hopefully, no discernable heat!! (Won't be an issue to ascertain what wiring what goes where, I, thankfully, traced/extended the wiring/cabling after the first "Oops.".... 🙂) Off to Jaycar tomorrow!! (Need some more "Veroboard" also.) Cheers and regards to yourself and Carl for the help/advice, much appreciated!! Harry.

I thought that I'd try and improve after the Tear Down.... In fact, I should have just continued with the Base Ki, maybe. Maybe, the Fibre Optic approach would have been better, one or two light sources.... Live and Learn I guess.

johnothanswift Posted January 18, 2019 Share #51 Posted January 18, 2019 After many years of plastic I'm currently building a Billings Roar Ege, very slowly :). And my next, or next,next is an Artesania Latina full interior Bounty. Frankly, after looking at the builds here of this model I'm looking at upskilling my wood skills a lot before even attempting this kit in my stash. But I'm finding that wood is, in many ways, a far more enjoyable medium to work on than plastic. Quote Link to comment Share on other sites More sharing options...
hof00 Posted January 18, 2019 Author Share #52 Posted January 18, 2019 Hi Chap, Yup "Wood" ship models have been described to me, in the past, as the "Pinnacle" of modelling. Got a Build Log/Photos? Yup, from what I have seen, the A/L Bounty is a challenge, so is your current build, (I'm scared of Clinker stuff!....) Many years of Plastic Modelling here also and I have a :1/72 Wolfpack" U-Boat and 1/200 Bismarck waiting in the wings.... I do however prefer the wood stuff. After "Sanson" I'll be looking at the Flying Cloud, (Mamoli), Maybe.... (I love the Clippers, they are fairly easy to build, (Hull is "Pointy" but complex Rigging.) Great to make your acquaintance!!

I think that the next step will be to complete the Wheel House, Navigation Light "Boxes," install and complete the first Planking before, sealing the Circuit inside....) As previously stated, once the Planking is done, I cannot access the Resistor N/W, if "Lights go out," there's sod all I can do about it. 🙂 Cheers....HOF. keelhauled 1 Quote Completed Builds: A/L Bluenose II A/L Mare Nostrum Sergal/Mantua Cutty Sark A/L Pen Duick A/L Fulgaro Amati/Partworks 1/200 Bismarck A/L Sanson Link to comment Share on other sites More sharing options...

Hi Chap, I have contemplated this, "The Scrapyard," more than once.... 🙂 I think that I just have to carry on for the mo and see where it lands. Yup the "Christmas" lights are a little bright but should tone down a bit after the Brass Shrouds/Covers go on them. The other LED's are a little bright also, never mind, I cant do much about it, I'd have to re-engineer the Resistor N/W, (Again), and the LED's under the Deck are pretty firmly affixed with CA, so, to late, too bad.... (It is what it is....) I guess time will tell, I have to "Persevere" for now, and if the lights if it gets too much, well, the afore mentioned "Scrapyard." (Don't want to do that, the last resort....)

johnothanswift Posted January 24, 2019 Share #60 Posted January 24, 2019 (edited) As they are LED's and don't get hot why not dull them down with something like Tamiya acrylic paint. I'd suggest experimenting with ones not on the model yet first 😃 to test the theory but that should dull them nicely and let you adjust the colour.
