LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 5 days ago
Hi Pete, Thanks 😊 Yep, I decided to stick with 4 lights cos tha's all I see on the original 'WYEFORCE'. Yep again! I do intend to modify the two lights on the stub mast; 1 yellow 'Towing' and 1 white 'Stern'. I will also fit a wheelhouse light. Decided to do it 'fluorescent' style by fitting 2 white 3mm LEDs in the ends of a long block of 5mm perspex. After that the 2 work-deck floodlights, lower cabin lights and 2 deck lamps 1 each side of the main cabin. I'll probably link the cabin and deck lights so that they all come on together. Now pondering how to build a miniature working diesel genny to power them all😁 Good luck with your divider! You will have more wires to squash in than I did so I doubt there's room. Have fun trying. I separated the wires quite easily by keeping all the negative legs of the LEDs (that's the leg going to the larger electrode in the diode) on one side and soldering them to the brass wire negative rail first. Then I took colour coded thin 'hook-up' wire to each LED in turn; working from the top down. Cut the LED leg to 1/4", stripped the hook-up wire back 1/4", twisted the wire strands together and tinned it. Tin the LED leg as well and bend it 90° down the mast. Then it's easy to solder the wire cleanly to the LED keeping it well away from any other wires. When all was connected, and tested OK, I stuck the wires down with thick gel super glue so they can't wander about. To fit the LEDs to the mast, I removed the brackets; removed the dummy lights with a razor saw, filed the mounting flat and drilled holes for the LED legs in them, using a 0.75mm drill bit in a pin chuck, and glued the LEDs on with gluper sue. Then I bent the leads 90° back towards the mast and drilled 0.75mm holes horizontally into the mast so I could literally 'plug' the lamp bracket complete with LED straight in and glue it down. Painted matt black the leads become invisible, as in 3rd pic above😉 Winch: at least your version of the model seems to HAVE a winch! Or where did those two pics come from? Mine ain't got nuffink, just a big 'ole at the back of the cabin😭 All the best, Doug 😎

Mornin' Pete (it is in Germany anyway!) I agree, there are lots of details and 'standard equipment' missing from the basic model. You can see the winch and Life Raft canister in one of the photos of the original I posted above. Re Mast wiring; don't fiddle about putting a divider in the mast. It'll just get in the way. Attached is a pic of my modified mast. I used a 0.5mm brass wire on the right-hand side for the earth return. Wire is better than rod cos it's flexible (can be pushed into the corner). I glued it in with gel Gluper Sue WHEN all connections were soldered and tested. The LEDs are standard domed lens types. I ground the tops flat and painted the tops with several coats of matt black until it was opaque. After testing I closed off the mast with some plasticard and fitted ladder rungs made of copper wire. I also added the missing antenna cables to the bottom of the VHF IMM antennas, 0.5mm brass wire. (Some time I'll also fit the missing GPS antenna and anemometer.) Then painted the mast matt black. I then turned my attention to the searchlight and red/green NAV lights. First I stripped the wheelhouse roof and painted it white as in the original. On my model it was grey🤔 Then I drilled out the searchlight to accept a 5mm Bright White LED. You won't have to do this cos you have a later version with lights, mine had none 😭 Then had to paint the searchlight with several coats of matt black. Otherwise it just glowed all round! Pics show construction stages and finished lighting effect. All wires inside the wheelhouse roof I super glued to the ceiling and ran them down inside the funnels (stacks to you guys across the pond!😉) ready for connection to a switch board in the hull. While I was at it I rubbed the false Southampton name off the cabin using a 1000 grit Tamiya sponge and am preparing inkjet printed decals with the correct Wyeforce name and logo. Have fun getting all lit up Pete,😁 Cheers, Doug 😎 PS Attached some pics showing the original 'Southampton' 😉 and making obvious what's missing on the model 🤔

Hi, Doug: I hope all is well. FYI, I’ve received all but one of my parts orders needed for the LED Mast Light project. The flat top LEDs arrived today & will be perfect for Nav lights. I don’t know if I mentioned this before, but a while ago I decided that instead of starting work right away it would be best to wait until everything I need for the project is on hand. While waiting for parts to arrive (& mysterious eye infections to clear up) I looked the boat’s Cabin & Pilot House over & made a list of details I want to add, changes or replace, not least of which is the conspicuous absence of a towing winch. Other things like adding a life raft canister, better looking life rings, fire extinguishers, etc. will come later, after completing the Mast LED Nav lights & wiring changes per your design. This brings me back around to a wiring question. Some time ago we discussed using a common ground bus inside the Mast & soldering each of the six “-“ leads to it rather than using six wires to do the same job. I plan to put a plastic divider piece up the middle of the Mast & run the six “+” LED wires on one side. The other side will have the bare ground bus onto which the “-“ leads of each LED will be soldered. The question is: what gauge should the bus be? I was thinking of using a length of brass rod but I don’t know what diameter to use. What do you think? Thanks, Pete

PT 109 upgrade? by RNinMunich Fleet Admiral!   Posted: 30 days ago
Aha! Agreed, although I believe there is one restored and sea worthy in the states!? But that's not at all what you wrote; brain ahead of fingers again. Know the feeling. No matter, Back to the LEDS 🤔 Ciao Doug 😎

Martin's Taycol Conversion Boards by RNinMunich Fleet Admiral!   Posted: 30 days ago
Howdy Ed, Yep, will do. Have taken some pics along the way. Mast lights and searchlight are working. Red/Green Nav lights fitted (had to spray the roof the right colour first - white not grey!) but not wired up yet. About to do that now. After that the two aft facing Towing lights and deck flood lights. Also discovered that there should be two deck lights P&S of the main cabin😉 Will need the miniscule chip LEDs for those - Now, where did I put my microscope🤓🤔 In fact while researching I found there's a whole list of 'bits' missing. Not least the Life Raft, which should be behind the wheelhouse!!😲 (In God we trust - But just in case we want a Life Raft 😁) Have also started drafting new decals with the correct owner's logo and fonts. The wiring is only a lash up at the moment to check that everything works. As soon as I'm happy, with resistors an' all, I'll fit some mini connectors. More soon, (in a different thread cos this will bore the pants off Martin. A NO Lights Man!) That reminds me of a banner I once saw above the RAF Controllers at the London Air Traffic Control Centre. "RAF controllers do it in the dark" 😲😉 The civil side was brightly lit, other side of the wall the RAF guys had minimal desk lighting only. Cheers, Doug 😎

Old Futaba servo wiring... by onetenor Fleet Admiral!   Posted: 1 month ago
Doug When you get the circuit sorted for the B/B tester I'd like a copy please. Will it be switchable wavelength wise. I/E one to the other? Re . testing LEDS I use my multimeter set to diode testing Eezy Peezy.🤓👍

Cheap motor for a quick fit, but what prop gents?... by RNinMunich Fleet Admiral!   Posted: 1 month ago
Mornin' (😲) Martin., First off; the Hornet ain't mine, wish it was 🤔 I had a look on the Lesro Models site to get an idea of what the prop would have to shove! Was surprised to see it is my hull with a different lid! The current kit is 80 quid BTW. To the motor / ESC; Yeah, you could use an 11.1V LiPo on that motor. BUT your ESCs probably are not LiPo SAFE! Which means that they won't have an automatic shut off or slow down function for when the battery is getting near it's Suicide voltage; roughly anything below 3.0V. Some say 2.7 but I don't risk that. So you would have to be cautious on the first runs and frequently check the remaining volts to learn how long you can run before you risk damaging the LiPo. If you can squash it in how about a 12V 10 cell NiMh? That should give you a good turn of speed with the 35mil prop. Bit heavy though🤔 I use an 11.1V LiPo in my Sea Scout with a 1000kV brushless. i.e. ca 11.100 rpm full bore, and that lifts her snout quite well as you have seen. Hope you find the motor, you seem to make a habit of 'mislaying' motors! Have you found the Supermarine yet? Apropos Supermarine; I've just been asked to renovate one 😉 Looking forward to that so I can see it's coil construction first hand. Will help me refine the mod instructions for you.😉 ESCs; mail me any printing on them and photos and maybe I can identify them and their capabilities. The switch makes me think maybe they do have BEC! The leads don't go nowhere cos it's only there to switch on the ESC / BEC. In my experience only ESCs with BEC have such a switch. Easy way to find out; set up an RX with a servo, plug the ESC lead into the RX, stick a battery on the ESC WITHOUT motor, switch on the TX and the ESC (move the switch to the end where two wires are connected) and see if the servo responds to the TX or any LEDs flash on the RX. Or just measure the volts across the red and black wires on the RX plug! If the ESC has a heat sink I don't think you need worry too much about current capability. Use your natty new Wattmeter to measure the current drawn by the motor as you run it slowly up to full speed. 😉 Don't think you need worry about volts either; all but the teeny weeny ones (like the fingernail size 3.7V ESCs I just bought for my Plastic Magic ships with only a 1S LiPo supply) can normally handle at least 12V, it's current that usually kills 'em😡 Sorry; Your electro-boards are still here, haven't been too mobile lately🤔 So I ordered some prepaid DHL labels (arriving Thursday) and will then get them to collect your parcel from me. Will email when they're finally underway. Cheers, Doug 😎

Hi chaps, just for info, 'Bright Components' do 6 different colours of flashing LEDs very reasonably priced. Also flickering - very interesting.😉

Hi I also have a collection of 1:350 kits; HMS Ark Royal (carrier), HMS Hood, USS Enterprise The Big 'E', Bismarck and Titanic. Reckon I'll probably have to use the tiny chip LEDs for those.😲🤓 Can't wait to see photos / vids of 'Curiosity' in action👍

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 2 months ago
Doug: The glass paint is indeed a great idea. It’s an idea that I’ll consider seriously whenever a situation arises that’ll make using colored LEDs impractical, such as on my 1:350 SS Normandie kit, maybe? Finding the flat-topped LEDs made staying with your original design an easy choice. Regardless of when the job gets done, I can just imagine launching the tug late in the day, waiting until just before dusk, then switching the lights on with the transmitter’s function buttons until they’re all shining & reflecting in the water. It doesn’t get much better than that. Thanks, Pete

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Pete, 👍 The glass paint was only a 'wild card' suggestion when I saw that you had dozens of white LEDs 😉 Just happened to see it in the cupboard, I'd used it on some 3V bulbs for my destroyer years ago. Dunno about mine being finished first. I've got a few other things cooking before I'll get back to to the Southampton. On the other hand ...... 😁😁 Good luck👍 Cheers, Doug 😎 PS make a chain of the white LEDs and use them for 'dressing ship'! 😁

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 2 months ago
Hey, Doug: Thanks again. I’ll take your suggestions & mark up your drawing accordingly. I still need to finish clearing away the molded-on plastic details inside the mast, then order the parts for this project. I generally don’t like starting any kind of project until everything needed is on hand (everything I think I’ll need, that is). You’ll probably have your tug’s lighting finished long before I do. I’m looking forward to being able to use my desktop PC comfortably again. Every word & photo I’ve posted on this fantastic site so far has been typed on or photographed with my trusty iPhone 6. It’s very convenient but it’s awfully hard on my eyes. The little touch keyboard is a challenge for my beat up old dinner plate-size mitts, too. Anyway, when my tug’s new lighting & modified controls are all built, tested & buttoned up I’d like to combine your drawing, spreadsheets & various notes with my own hen scratches, notes & miscellaneous observations into a CAD drawing. Naturally you’ll be cited as the project EE/electronics designer on the drawing’s title block. I’m confident in saying that your tug’s lighting will use factory colored LEDs, not hand-colored white ones. It would be a shame if I didn’t follow suit & use your design for colored LEDs as originally intended. I’ll much more satisfied knowing that the new navigation lights & other changes were done the right way. The glass paint is coming off my list! Thanks, Pete

Good afternoon, Doug: I found the flat-topped LEDs at Ali Express. The url for these LEDs is: https://m.aliexpress.com/item/32462840779.html? I’ve included another photo of the LED that has a dimensioned sketch with it. FYI, I’ve ordered lots of stuff from Ali Express, such as hobby tools & supplies, electronic components, gizmos, gewgaws & doodads. One particularly nice thing I purchased is a wireless guitar-to-amp device. Everything I’ve bought has been top-quality, but because nearly everything ships from China it can take several weeks to be delivered to me here in Massachusetts. Now for the inevitable question: If I use your drawing as it is now & modified the circuit board, added the resistors as you’ve already indicated & connected white LEDs in all locations, everything would work OK, but some LEDs would be brighter than others because your design was based on using colored LEDs. Correct? Based on your observations & experience would any harm be done? Don’t worry, I’m not going to jump the gun without your final drawing (which I’m in no rush for...take your time). I’m just curious. Which leads to my last remark, for now. For some reason my wife thinks I ask far more questions than “normal” people do. She claims that I’m exceedingly curious. I don’t know what she means, but her offhand remarks have inspired me to rechristen the Richardson. When the LED project is complete & the tug is all ship-shape & Bristol fashion, her new name will be: “Curiosity”.

Hello, Doug: I stumbled upon some other LEDs that are particularly well suited for navigation lights. They have the same specs as the rectangular LEDs shown in the photo I posted recently, but what makes them ideal for me is that they’re flat-topped, not domed. They’re cylindrical in shape, still 3mm diameter & look quite similar to ship’s lanterns (see photo). With your experience you’ve probably seen these before, but I was surprised to see them. My plan is similar to the original idea for making scale lights, except as we last discussed white LEDs will be used everywhere, colored by dipping them in appropriately colored glass paint. For the mast lights that will remain white but need to emit light at a given angle, I’ll mask & paint the LED’s body the same color as the mast, resulting in a clear aperture. 4mm & 2.5mm diameter disks punched from sheet styrene, glued one atop the other, then painted & glued to the top of each LED will form the light’s top covers. What do you think? BTW, the flat-top LEDs are also available in a variety of colors. If anyone is interested I’ll post the url to their location. Thanks, Pete

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 2 months ago
Hey, Doug: Thanks for the excellent advice. The “dip/dry/repeat if necessary” technique for coloring LEDs makes the most sense. Brush painting transparent colors always seems to result in a very blotchy finish. Now that I can see well again I think I’ll turn my attention to removing the molded-on ladder rungs inside the mast. Sounds like a job for my little cordless Dremel. Thanks, Pete
