The wheelhouse navigation light. by mturpin013 Fleet Admiral!   Posted: 9 days ago
This is a small item but very visible on the wheelhouse and since the standard for this item has been set I have to follow suit. So first of all get some 3mm blue LEDs ordered and then it’s on with preparing the white metal body. I used by hand as suggested a series of drills increasing in diameter until 3.1 dia was reached but only 2/3 down the length from the front the smaller hole (1.5mm) was bored right through for the wires to exit. Arrival of the LEDs, first check the LED using my power supply, just over 3 volts seems to illuminate to the correct level. Next was to remove the shoulder on its plastic casing so the whole body does not exceed 3mm over its length and lightly abrade the outside to give a diffused light. Next cut the LED legs to 2mm from the plastic casing noting which is positive, next prepare the wires. I used Futaba servo wire cable 22awg which is very flexible and with the white signal wire stripped off leaving a red and black wire. These were tinned and cropped to 2mm and then quickly soldered to the appropriate terminal. Next check the LED still works! first hurdle over, I now needed to check the that when the LED goes into the body it doesn’t short out so checking the diameter over the widest part which is over the soldered terminals this was 0.1 below 3mm. I decided that shrink sleeve was too thick so I mixed some epoxy resin and coated all around the terminals, this proved to be satisfactory in both non-conductivity and dimensionally. Now the final test, using some aliphatic wood glue I slid the LED into the body whilst it was illuminated as it was a tight push fit, bingo it’s still lit – leave to set. I used aliphatic glue, as it would be easier to remove should I ever have to change the LED. The body still needs painting white but this will be done with all the other fittings at a later stage.

Equipment wire by b111yboy71 Seaman   Posted: 18 days ago
Hello, try looking for old 25way data cables at your local car boot sale. The cores are multi-coloured and very thin. Most LEDs only use a breath of current to drive them so you won't start a fire! Here's a tip about dropper resistors for LEDs: put them at the power supply end where you can tie them down securely. Also, the formula for finding the resistance you need is: R equals Volts(supply) minus Volts needed by LED (Vf) divided by the required LED current (If). So, say 12V supply, 2V LED wanting 15mA = 12-2=10/.015 = 666.667, so you'd use the nearest value above, which would be 680ohms. Easy! The size of the resistor in watts/milliwatts is found by I(current) times E(volts), so 10X.015=.15W, or 150mW. Hope I'm not teaching an old sea dog new tricks! Starting a new Firefloat - oh boy.😲

USCG POINT GLAS by Inkoust Fleet Admiral!   Posted: 30 days ago
The 70-year US Coast Guard semi-deck. All-metal construction, 2 x MIG 480 motor, standard servo, model illuminated on two circuits. One light mast, position lights and cabin. The second lighting circuit in the hull of the ship and the outdoor lighting around the superstructure. There are no labels on the model yet, I'm waiting for the fabrication. Battery 1 x LiPol 4000 mA. The total construction took me half a year. I made the hull made of laminate from my friend in Slovakia. The superstructures themselves are made of laminated boards. Part of the light bulbs are 6V lamps and the strobe with positional lights are the LEDs of the light triggering through two RC switches.😉

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 1 month ago
Hi Pete, welcome back😊 Glad your eyeballs have cleared up 👍 Just ordered new goggles yesterday, should be here end of the month, then I can fiddle with 1mm LEDs again - maybe😉 No, I didn't put a plug and socket at the base of the mast. I hard wired it into connections in the wheelhouse roof. Then took all the wires down through the funnels until they poked out the bottom of the main cabin. That's it for now. The mast is not glued in, it's a tight push fit so can still be folded down a bit. Later I'll make the little distribution board and put the plug and socket there so I can still remove the whole superstructure for maintenance. No again, I haven't done any more on the Southampton yet. Been busy fiddling with my fish cutter Gina 2, hull preparation and preliminary coat of white paint, and cleaning up Colin's vintage Taycol field coil motor. See Electrical Blogs 'Taycol Supermarine'. Cheers, Doug 😎

if your still thinking about the cabin light you may like to think about using a surface mounted LED https://www.ebay.co.uk/itm/Surface-Mounted-LEDs-10-Pack-Choo... Just to give you an idea

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 1 month ago
Hello, Doug! I’m happy to report that my eyes are finally healed & I’m ready to get cracking on my tug’s LED lighting improvement project. Needless to say it’s so fantastic to be able to see again. The infection was so bad that I had to move around the house for weeks with at least one hand on the wall or I was in danger of falling or walking into the china cabinet. I lost what’s called “stereo vision” & had no depth perception. It was a nightmare to say the least, especially considering that the source of the infection remains unknown. But I just had a checkup at the ophthalmologist‘s office & I was given the happy news that all traces of the infection are completely gone. Hallelujah!🙏🏼👁👁 BTW, did you complete your tug’s mast LED lighting project? I recall that you had finished up the mast itself & had its LEDs working. Were you able to reinstall the mast in the pilot house roof & get everything back together without any problems? At one point you had mentioned possibly making a plug & socket arrangement for the mast so that it could be removed for safer transport to the lake. Were you able to follow through with that plan or was it just is easy to simply re-install the mast? finished for your dog? If so, how did it come out? I hope all is well with you & that your many projects are all turning out successfully.

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 2 months 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 🤔

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 2 months ago
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: 3 months 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: 3 months 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: 3 months 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: 3 months 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👍
