I've decided to go ahead and light under my station awnings with the LED strips. You really don't see the lighting fittings from any viewing angle!

I've used the soldering iron to burn holes to feed the wires, that worked very nicely.

The lighting colour for outdoor lights is cool white to contrast indoor warm light (to mix things up a bit). I'll have to wait till this evening to see if I like the effect.

Here's how the under canopy lighting looks, as mentioned it's cool white to contrast warm white interior lights. May notch the brightness down a bit, it' on 3.3k resistor like the other LEDS but appears brighter being not behind any walls.





My back scene boards have needed 4 coats of white primer to make them pure white as possible. They are now ready for artwork style painting!

I am trying to get hold of 1:160 toilet rolls, but everywhere has sold out. Any idea where I could get some? :smiley-laughing:

@ntpntpntp can I just dasiy chain these? If so, will it need less resistance between the power bus and the start of the chain? 🤔



Obiously I could just try it, like Farady did when he stood out on hilltops in thunderstorms holding a metal rod above his head. :D

2 coats of sealent, 4 coats of white primer. Might need a light sand, but nearly ready with the backscene!

@ntpntpntp can I just dasiy chain these [three LED strip segments]? If so, will it need less resistance between the power bus and the start of the chain? 🤔

As I understand it each segment of 3 LEDs already has a resistor in the circuit intended for 12V, so they're not going to work when connected in a series "daisy chain" unless you're running from a higher voltage multiple of 12V. With the long LED strips each sub-segment of 3 is wired in parallel across the 12V supply, which is why you can cut the strip at strategic points.

You can add a single additional series resistor to each strip to reduce the brightness, and that resistance will apply to each sub-segment. That's what you've been doing already I think, the same as I did with my shed lighting






btw, those LED filaments I mentioned a while back arrived recently.  Quite neat, though still rather larger than a scale strip light would be of course.  They're rated at 50mA 3V  though I found them quite acceptable at 10mA with suitable resistance.   






At low brightness you can see the individual LED chips - in this blurry photo they're more visible in the reflection off my resistance box!

Hmm over to plan 'B' then. Where can I get very narrow tubes to act as down pipes containing two wires each?

So if we all end up being locked in our homes for a month, we may need to find a hobby which requires little inter-personal contact, is very time-consuming and burns few calories - oh hang on a minute.... :hmmm: :D

I have used 'Plastruct' or 'Evergreen' products to hide wiring inside buildings. It can be bought as tubes or square section - from model shops or online.

Ah did not know styrene came in that form - superb thanks for tip!!! :thumbsup: :beers:

@Globibahn so for your under-canopy lights you just need to wire them in parallel, with a single pair of wires running down one of the legs - maybe painted to look like drainpipes? fit an additional resistor in one wire under the baseboard to control the light output.

You might also like to look into sticky-backed thin copper strip which can be used as a conductor - see my photo earlier.


[edit] If by "daisy chain" you meant linking from one to the other with two wires then yes you can do that. It would be parallel wiring in terms of each strip running from the same 12V (each strip contains parallel wiring to pass from one end to the other). I usually consider daisy-chain to mean one wire from one thing to the next in series, with a single return wire at the end of the chain.

Fab, I'm with oyu now Nick.

So this is totally ok if I get you rightly

(with addition of a resistor, of course, between power bus and the parallel LEDs)
