Thanks Ian, not got an I phone, but found an app that has nav light rules on it.......... :-))


Just had notification that my mast lamps have been completed and are on their way over to me, so should be here mid week.


I have done 2 sizes, both take a standard 3mm LED. One is 5mm dia the other is 6mm dia. The idea is to fit coloured LED in, paint the top and bottom black (mask off area if needs to be less than 360 deg view). One leg (neg) to be soldered directly to the mast, the other will be cut very short with a length of KYNAR wire soldered to that and sealed off, threaded through very small hole in the mast and down to a master resistor board (yet to be made). Hope to get some pics as it progresses.


If it fails, I shall just use the standard 3mm LED's with no cover.....I am hoping it looks life like, if not it only cost a tad over a tenner for them.


Fingers crossed.

Well my lamps arrived from shapeways and bit undecided about the sizes. Going to paint the cap and base then put some electrons down it and see how they look.

Waiting patiently whilst the electrons line up and slide down the wires. :o
Don't forget electrons like the outside of the wire ;)

Wait no more Ned...... :D


Put a bit of matt black on (not happy with Revell paint).
Tried with a standard 3mm coloured LED but was too faint, so popped in a super bright clear lens LED and happy. Just need to redo the matt black and then can get on.

Put sorting the LED's out on hold for the moment as waiting for some brass strip and some 4mm clear tube.


So made an effort to get the towing guide finished. Well it is all done bar painting, needs a good clean and some etch primer on it then can put top coat of orange on.

Fine bit of brass work Stew. :-))
Seems a pity to paint it.

Slow progress at moment as it is too damn cold to do more than 15 to 20 minutes in workshop!
Added light platforms and whip antenna head onto the mast. Placed my 3D printed lamp so can see for scale, still waiting for some 4mm clear styrene tube so I can make some smaller ones, mainly to see the difference. Going to solder negative leg to platform and thread 0.4mm cable from positive leg in through small hole and down the inside of the mast, these will then be threaded under the forcastle deck and into lighting control box, which has yet to be designed and made!

A little more done despite the cold.


Sprayed etch primer on cable guide.


Finished soldering the mast, damn fiddly those rungs! And a couple of coats of etch primer. Once dry can fit LED's and wires.


Thanks for watching.

Well, after many months and great loss of hair and a near moment of giving up, I finally managed to complete the front mast, with working lights. These will be controlled by my Tx via an onboard Picaxe chip through a number of darlington chips so hopefully I can sequence all the lights to signal differing operating conditions set out in the maritime rules.........and maybe some funky light show.......don't quite know yet on that last one, see how the rest of the build goes now.

Cheers guys.
They are a bit too bright at the moment, they are running at 20ma, need a 1K resistor soldering to each cable next to bring them down to 10ma output which will be bright enough....... :-))
