Re: Conductive paint

I just realised those LEDs are in the wrong place relative to your ground signal but the theory is still the same.

Re: Conductive paint

Now the problem with Drawing2.png is that the resistor is getting shared with two parallel LEDs, in one position a red and yellow and in the other two yellows. So in Pos 1 you have the same issue of having one LED with a lower fwd voltage than the other so the red LED will be off or at least not nea...

Indeed. That's the main reason adding the resistor. That way you cannot exceed the forward voltage drop of the LED regardless of the supply (within reason).

Re: Conductive paint

I've watched the video a few times to check. You have the Yellow and black wires in the same socket on the terminal so is the red the common +ve? I'd assumed initially that the red wire was for red LED and the yellow wires were for the yellow LEDs but then do you use black for the positive? :shock: ...

Especially if you use a CDU.


Why? Not arguing, I'd really like to know. Do they not handle high currents well?

Re: Seep v Solenoid difference?

Can be difficult to position under your points. I recently came across and bought this tool for easier fitting of seep point motors. https://www.newrailwaymodellers.co.uk/Forums/viewtopic.php?f=22&t=48176&start=735#p669871 I haven't tried it yet but it looks the business for new modellers l...

Re: Seep v Solenoid difference?

SEEP are also solenoid. They work the same as Peco and Hornby point motors. Pros Inbuilt switch contact can be used for live frog polarity switching or indication on a control panel. Screw holes for mounting under base board. Cons Use more current. Can be difficult to position under your points. htt...

What wrote those off for me was the quoted £3.55 for postage.


Oh is that a lot? I've no idea what UK postage costs are like. You'd think they'd survive a trip in a padded bag though.

But is £9.95 a lot of money for 3 windows? I think I'd make my own if it was only for modelling purposes and not collectable item purposes.

Re: Slow return.

I have put a feed at the bottom right but think I need one at the top left to feed the sidings on the top right. I'd put one top middle between the two points. My other question is for lighting in the cabs of the units (non DCC) would leds work on 12v DC would very in light as the front lights on m...

Re: Gaps in track

The trackbase gives off horrible acrid fumes if the soldering iron bit touches it, Simply slicing off the chairs sometimes isn't enough as you have to also accommodate the thickness of the rail joiner I have a temp controlled soldering iron so I turned it right down. I found the method quicker and ...
