Taycol Supemarine Resurrection by RNinMunich Fleet Admiral!   Posted: 23 hours ago
Shucks! An I was hopin' you'd build me a little 4 cylinder diesel for me to run a brushed motor as a Genny for all the lighting on my ships! Or for the diesel electric propulsion on my Type 45. Now wouldn't that be cool!?😁 BTW Some of Nick Carters tips an tricks showed me how to convert one of my tools to something that'll do what I want! So, out with the Proxxon mini-grinder😉 Cheers, Doug PS It wasn't a wrong steer cos it led me to all sorts of useful 'stuff' and above all helpful info👍

W1 by jbkiwi Chief Petty Officer   Posted: 3 days ago
This is my scratch built 36" RNZAF British Power Boat 64' HSL (arrived in NZ 1940). I actually went on board this vessel in 1968 when it was still in original form (the RNZAF having disposed of it in the 50s) This vessel is still around and has been recently re modelled (2nd time since early 70s) and I was lucky last year to have met the present owner and go on board (2nd time in 49yrs!)and take a few photos. The vessel was modified a number of times by the RNZAF over the years (air intakes, removal of the fore deck machine guns, wheelhouse turret etc so I sort of went in the middle. I found a few drawings of the type in an old mag which had side and top views plus the bulkheads and their positions, so I took them along to a copying shop and kept enlarging them until I had the desired proportions. This worked out quite well and using a few methods from other models I had built, managed to frame (ply) the hull and then fully strip plank it in balsa. It was then fiber glassed. The deck is ply, lined and varnish stained. The wheelhouse is varnished balsa with the top removable for access. The wheelhouse interior has detail such as controls, instrument panels, skipper, steps to wardroom etc but is not too detailed as it is not seen. The boat has full lighting by remote switch, lights are all LED. The propulsion side has dual everything (motors, ESCs, sound units), would have had 3x but ran out of space! Motors are 28mm 2200Kv water jacketed in-runners (cooled by remotely switched pump) using 30A Chinese ESCs (have 5A BEC, Fwd and Rev). Twin sound units are 'GT Power' car units which have around 40 different sound selections, from Cosworths to diesels and are computer programmable (as well as manually on the unit ) for various functions. I am using one of the v8 sounds (8 cyls short in my application) which I think is as near as you are going to get to 3 Napier Sea Lions (for which there is obviously no sound available) They 'start' 'Idle' and are fully proportional in fwd and rev and can sound quite realistic (will attempt to put up a vid later). Batteries are 2x 2200mah 2s 20c LiPos which will last around 2hrs at least of sailing (they also run the sound units) Still have a few small things left to do (have just made wheelhouse air intakes) but don't want to get too fiddly. Just want to keep it a practical model.

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 6 days ago
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 🤔

1.5v AA Li-Fe/Li-ion/Li-po batteries by RNinMunich Fleet Admiral!   Posted: 25 days ago
OK, found some! https://www.ebay.com/itm/8pcs-JUGEE-3000mWh-1-5V-rechargeabl... Interesting that they all quote mWh instead of mAh! I.e. energy instead of capacity! Power being V x I (Amps) divide the mWh rating by the nominal voltage to get an approximation of the capacity in mAh. Saves integrating across the varying voltage during a discharge cycle, i.e.'On Load' 😉 Thus these 3000mWh cells seem to have a capacity of around 1800mAh. Which is considerably less than the typical 2500mAh of an alkaline or NiMh AA cell. Also, to produce the output voltage of 1.5V from 3.7V Lithium chemistry the cells have an internal voltage regulator, which also must consume some power, albeit miniscule. Something else which can go wrong🤔 Summary; yer pays yer money and takes yer choice! Seem rather expensive to me for what they deliver. Depends what you want to use them for. Might be useful in my Sony camera but I wouldn't use them for any high current load in a model. OK perhaps for LED lighting circuits which only need a few tens of mA. Here a list of battery types, sizes and chemistries for reference. https://www.wikiwand.com/en/List_of_battery_sizes#/overview Cheers, 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 RNinMunich Fleet Admiral!   Posted: 1 month ago
Hi Martin, would have thought the name was self explanatory! 😉 In the attached pic you can see my Robbe Servo Tester at the top. I used it to simulate the proportional signal from a receiver while testing your Taycol converter boards, not to power the motor.😲 Motor power came from the mains PSU in pic two, the battery eliminator circuit (BEC) in the ESC provided power to the tester. The tester provides the signal to drive servos, or in this case an ESC, and saves the faff of setting up TX and RX and fiddling with batteries when I want to test a circuit or function before building it into a boat. Cheers, Doug 😎 Oh, and by the way; when you get into lighting for your boats don't forget to buy an LED Tester as well 😁😁 You could also think about a simple RF Detector / Meter to check if your TX is actually transmitting 😁 Like I did with your TX using a home brew device - OR you could wait til I get around to publishing a Build Blog for the refined version I am making using a couple of RF diodes and a sensitive 300microamp meter 😊

Sea Trials and mods. by robbob Fleet Admiral!   Posted: 1 month ago
It’s been a while since the boat had it’s maiden voyage on the lake at St. Albans and I’m pleased to report that it looks really good in the water and goes like stink if you open up the throttle. Sadly I still don’t have any decent video of the boat yet as I can’t film and drive the thing at the same time, but I do have some static wide shots from my GoPro. When I do the video I’ll ask a cameraman mate to do the honours, maybe I’ll put the GoPro on the bow and then the stern to get some low action shots…the storyboard is already building in my head!! These early runs were great as they showed up some minor problems that needed attending to. I found that it needed ballasting slightly as it was not sitting on the waterline evenly from side to side so I flattened out some old lead water pipe and cut it into small sections so that I could add ballast incrementally. I did this in the ‘domestic test tank’ and once I was happy the lead pieces were fixed in place inside the hull with some super strong double sided tape. The ESC needed a little programming adjustment because I had forgotten to set the low battery level point to ‘off’ as I am using NiMh batteries and not LiPo’s , that was the cause of the short initial run time on the first outing…..DOH !! The batteries are now held in place by Velcro straps on some bearers that I added, otherwise a battery change involved cutting cable ties and replacing them at the lakeside…not very practical. The volt/amp/watt meter is also now on a proper bracket so that the display is more readable. I have also changed the charging connection from the nasty Tamiya connector to a nice little panel mount XT 60 connector that HobbyKing sell, it comes with a handy blanking plug that I have drilled for a retaining cord. I have also finally got around to upgrading the firmware on my Turnigy i6 radio to the 10 channel version so that I can assign the lighting to the switches properly and have the rotation of the searchlight on one of the two rotary knobs. I can use the old 6 channel RX in the new boat….blog coming soon.

Range Safety Launch? by NPJ Fleet Admiral!   Posted: 2 months ago
The ‘Range Safety Launch’…………. Intro. I am now the owner of this boat. Wooden, good hull lines and hull paint work but needing to be finished. I am told that it looks like it started life as a kit, but has had considerable modification to at least the above deck layout and detail. Advice is that it could be a rather simplified Range Safety Launch, but maybe I can use a little ‘artistic licence’ and just make it look interesting and capable. There are two main reasons for sharing this project. 1. I will undoubtedly need guidance 2. Maybe some of the information will assist others The hull is 44 inches ( 112cm ) long and 14 inches (36cm ) wide, it has two brushed MFA Torpedo 800 motors………. and weighs in currently at 15 lbs 4ozs (6.91 kgs). It is large enough for me to be able to work on reasonably comfortably and apart from the cabin/upper deck areas to be ‘improved’, I aim to introduce sound, lighting, active radar sweep, search light, together with maybe a deck hoist and water /fire monitor appliance. At my age it is difficult to tell the difference between wishful thinking and dementing…… However, the prime aim is to try and achieve at least some of this whilst having the boat usable during the current ‘season’. There is so much knowledge, good will and help available on this site that even before I touched a thing, information came pouring in. If anyone feels like making a contribution then please just ‘pile in’. Have ordered some parts so next time should have something to show. NPJ.

LED Tug Mast Navigation Lights by Rookysailor Lieutenant   Posted: 2 months ago
Strange that you should mention the Movie/book 'The Cruel Sea', have just bought the DVD from Ebay, looking forward to watching it once again. I have an old Revell corvette kit, and last month bought the NEW corvette kit from Revell which has most of the lighting in kit form, plus revolving radar, but very annoyed 😆to find out that there is no p/e parts or wooden decking as in the platinum edition, but it only cost me £100 + vat trade deal, sssh🤐 Cheers Peter😊

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

Richardson (to be renamed) by pittsfieldpete Lieutenant   Posted: 2 months ago
[Score: 9/10] 23" Richardson (to be renamed) Twin Propellors (3 Blade) Geared Powered by NiMH (7.2v) Batteries - Comments: LED navigation lighting will be added soon. RNinMunich (Doug) has been extremely generous with his time & talent with helping me with this project. With Doug's help all of the lights on the boat, including navigation, spotlight, aft deck lights & cabin interior, will all be controllable from the boat's existing 2.4gHz unmodified transmitter!

Martin's Taycol Conversion Boards by Westquay Fleet Admiral!   Posted: 2 months ago
My Boob. I was thinking you choose ESCs on watts and of course, it's amps. Our old school caretaker used to say It's the amps what kills ya, boy, as he wrestled with very dodgy wiring on the school's stage lighting! From what you say above, I wouldn't bother, but then the machine does all the other stuff too, so worth the 8 quid, I'm sure. Jeez, I'll be going about with a boot full of test gear! And there's me hates electrics. Thanks again, mate. Cheers, Martin

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 2 months ago
Hey, Ed: Yes, I’ll take several photos to document the project. I’ll shoot a video or two as well to highlight the differences between the tug’s original factory lighting & the new setup. I’ll shoot video of the tug out on the water at dusk, first with the light off, then with the lights on. It should look pretty good. It’ll be a while before anything gets posted because I still have to get all the parts. I have a lot of nasty medical stuff to deal with, too. Wish me luck. Thanks, Pete

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Pete, JFF I built a little 'breadboard' (now where's my peanut butter!?😁) to test your LED lighting configurations. Theory and calculation is fine but there's nowt like an acid test😉 Pics attached of the results (Christmas tree😊). Difficult to capture the colours due to the very bright white LEDs🤔 Will play with the resistors to bring up the yellows and dampen the whites a bit. The 3 yellows at the bottom are the deck and cabin lights. The 4 rows at the top are the mast lights, red and green self explanatory! Applied (battery) voltage is shown on the meter top left, current drawn in mA on the meter to the right. The circuits work fine from 6.0V upwards. Current drain is approx- 110mA @ 7.8V (fully charged 6 cell NiMh) 103mA @ 7.5V (probable voltage after running a little while) 90mA @ 7.2V (nominal NiMh battery voltage. It will flatten out at approx this voltage after running a while - until it suddenly collapses at the end!) 75mA @ 6.6V (voltage of FLAT 6 cell NiMh battery) 60mA @ 6.0V curiosity! Below this some LEDs switch off. Brightness is noticeably reduced. I think we can increase some resistors to reduce the current drawn without reducing the lighting effect😊 More info soon, I'm still experimenting, then I'll start modding my own tug😊 Cheers, Doug 😎

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 2 months ago
Mornin' Pete, Mon plaisir 😉 Yeah, those surface-mounted-devices are a bit fiddly. First thing is to clamp the board somehow so it can't slip. Second: PLENTY OF LIGHT!! Third: a small low power soldering iron, about 20W with a 1mm flat bit (chisel type). Temperature controlled if possible, set to about 200 - 250°C. Fourth: a solder sucker is very useful to suck the solder off the joints, and probably the little resistor as well 😉 Fifth: a pair of flat ended tweezers. The cross-over self-gripping type are very good for this task, also to put the wire link on afterwards. Finally: a large magnifying glass with stand, some have an area of extra strong magnification. Make sure it is very clean and the lighting does not cause shadows, reflections or refractions. Alternative: heat the resistor with a standard 25W iron until the joints melt and flick it off with a scalpel! 😲 Just make sure no solder lands anywhere else on the board and shorts something out!! Good luck👍 Cheers, Doug 😎 PS: my only concern with the mod is the current capacity of the switching chip / SMD transistors on the cct board. I hope they can cope with the increased current 😉 That's why I tried to optimise the resistors and layout to keep the total current on each output as low as possible while still turning the LEDs on! If something goes 'PoP' Don't call me - I'll call you! 😁
