CoombeTown Posted September 24, 2021 Share Posted September 24, 2021 Wow, that station building looks a treat! Really does feel GWR. I'm not usually a fan of embossed tiles but those look quite good, which manufacturer are they from? 1 1 Link to post Share on other sites More sharing options...
MrWolf Posted September 24, 2021 Author Share Posted September 24, 2021 Thanks, the slates are actually Wills' sheets, filed away at the exposed edges to reduce the thickness. On the station, all that they have had so far is a thin coat of Humbrol 67 Tank grey. In the past I have used individual strips of paper or plasticard to represent tiles but find the main thing is how you go about painting and weathering. 1 4 1 Link to post Share on other sites More sharing options...
RMweb Gold chuffinghell Posted September 24, 2021 RMweb Gold Share Posted September 24, 2021 Well I think it looks rubbish!….. ……haha just kidding it looks great, maybe needs some interior lighting? 1 Link to post Share on other sites More sharing options...
MrWolf Posted September 24, 2021 Author Share Posted September 24, 2021 It's surrounded by rubbish, I'll give you that! I really could do with clearing off the bodging bench. Otherwise I will soon be working on the windowsill... I'm thinking that for lighting, I am going to have to drill a hole in the baseboard and thread up a tube with the led on the end of it. I'm lighting the front room of the crossing keepers house, signal box, the stationmaster's office and the pay office of the garage. That will be all, as I don't want to overdo things. Plus the oil lamps on the platform aren't designed to work. 1 1 1 1 Link to post Share on other sites More sharing options...

Thats a shame those LEDs I’ve sent to you will need the voltage throttling back to about 3v because at 12v they are far too bright unless you need landing lights for the Stuka?

MrWolf Posted September 24, 2021 Author Share Posted September 24, 2021 I'm only lighting a couple of buildings for photography / highlighting interiors. I don't plan any night running, as I would have to start lighting the trains. Although the Dapol railcar has lights.... Link to post Share on other sites More sharing options...

RMweb Gold JustinDean Posted September 24, 2021 RMweb Gold Share Posted September 24, 2021 (edited) I would wire in a pot to the LED, adjust to the desired brightness then measure the pot’s resistance and replace with the closest value fixed resistor.

RMweb Gold Nick C Posted September 24, 2021 RMweb Gold Share Posted September 24, 2021 (edited) The simplest method to drop 12v to 3v is with a voltage divider - two resistors, the equation being Vout = (Vin×r2)/(r1+r2) - so for 3v, 1kohm and 330ohm would be suitable. Then connect them as follows: +12v ----- r1 ----- r2 ------ ground | 3v I might have so suitable resistors in my old electronics box, I'll try to find it over the weekend and have a look.

I should have said approximately 3v because I just turned the screw on the pot until I achieved the desired effect 1 1 Link to post Share on other sites More sharing options...

MrWolf Posted September 24, 2021 Author Share Posted September 24, 2021 Thanks @Nick CI would probably have over engineered the solution! That makes sense, I might even put a Pot into the circuit for fine tuning. At least with my buildings being constructed from Wills' armour plate I won't have problems with glowing walls!

RMweb Gold Nick C Posted September 24, 2021 RMweb Gold Share Posted September 24, 2021 (edited) If you're going to use a pot, you don't need to bother with the fixed resistors, it'll do the same job (you just use the middle pin as the output, the two outer pins power and ground) The exact values don't matter, it's the ratio between them that's important.
