Collaboration for DIY anchor light anyone?

bit late, sorry guys, but for pcb's try these people

low cost and they can do odd shapes as well.

Low cost is an understatement!

I've just priced up a 60mm x 60mm board, a run of 10 is quoted as costing $30 including shipping to the UK.

GHA, can you get a more realistic quote from them? I'd be happy to pay £10 for a board, which would make this a very affordable project.

Regards

Sorry if this sounds thick but I am after a anchor light that is either battery operated or can use a cigar lighter push in jobby that can fit on top of a pole. . In order to avoid any obstructions/ blank spots I could do with one that I can sit on say a fishing rod or other pole arrangement and plonk it into rod holder assembly that sits on my cabin roof. All I can see are those that hang down so always some obstruction by the thing that holds it up. Any suggestions from here would be welcome.

There are a number of battery operated alternatives. These are useful for a small boat and also a good backup for larger vessel.

The first two look i interesting as they apparently meet the 2nm legal requirement.

This is a general review of anchor lights that is a bit dated, but still interesting.

For my dinghy night light I have a 2m piece of 20mm pic pipe with one of those plastimo MOB beacon holders attached to one end, and a battery powered all-round white light clamped into it. You could do something like that. The light lasts for days - I once left it accidentally switched on and left the boat for four days - still bright when I came back.

thanks Ric I will look into that

thanks very much neolex some interesting links there- gosh them navisafe are expensive

 

[Mike k]

You could make your own?
LEDs, resistors, hot melt glue.

thanks but not that technical

One of these and a 8 pack of AA batteries in a battery holder

All mounted in a 50 mm PVC tube and end fittings. The bulb inside an upside down screw top jar will do the trick. If you add in a tilt switch you can turn it on and off with no external holes for water to get in.

Any thoughts on led wireing configuration?
All in parallel or maybe 4x6 series/parallel might be better​ if any fail.

The Crees are paralleled strings of 3 in series.

Mk1 had 5 strings, regulator set to 100mA so eash string 20mA (forward voltages very similar so the strings share the current pretty even).

Max current on the datasheet is 30mA .
