37lover Posted February 6, 2015 Share Posted February 6, 2015 Nice job, but the lights look very bright in the video. Do they appear that bright in real life? Might be worth fitting a resistor?Good to see the "mess" on the layout, plenty of work still going on! Link to comment Share on other sites More sharing options...
PJR_slo Posted February 6, 2015 Share Posted February 6, 2015 Hi Mike Thanks - looks good. Been keeping away from the TTS decoders as I have been unsure as to whether they would be OK with lights. May just invest in a couple not I'vs seen them working. Peter Link to comment Share on other sites More sharing options...
dynax Posted February 6, 2015 Author Share Posted February 6, 2015 Hi 37lover, no they're not as bright, each one has a 1k ohm resistor, and the glue i used has created a diffused lens, more by chance, Mike. Link to comment Share on other sites More sharing options...

Peter it is very fiddly and you have to solder wires to the pcb, which is very awkward, but i just took my time and didn't rush it, Mike. Link to comment Share on other sites More sharing options...
37lover Posted February 6, 2015 Share Posted February 6, 2015 Mike,I've got a Gadwell tts so won't be trying directional lights on that, but as my User name suggests I quite like the 37's so may well buy a tts in the not too distant future [impending birthday!]. Presumably you are connecting lights to the tts decoder. Did you have to solder connections to the decoder or are wires already fitted? Link to comment Share on other sites More sharing options...

Did you have to solder connections to the decoder or are wires already fitted?you have to remove the pcb to solder the wires, it is fiddly but can be done, i have actually used 10 leds in it, 6 white and 4 red, extra 2 white ones are for the cab at each end,Mike.

Fishmanoz Posted February 6, 2015 Share Posted February 6, 2015 Which PCb have you soldered to, the decoder itself or the board into which it plugs? I haven't actually seen one but I would have expected that all decoder pins go into the socket for a start, and from there, there would have been solder pads somewhere associated with each pin in that socket?

96RAF Posted February 7, 2015 Share Posted February 7, 2015 Easy job.The decoder socket as installed has the motor and pickup connections at the 4 corner pins, and the lights connect to the other 4 empty pins in the middle.As TTS has only the equivalent of a 2 function decoder (for lights) then you use the white/yellow for directional lights as normal (on F0), the green for the Aux lights (on F25) and the Blue for the lighting power.Its all very clearly shown in the TTS user manual (leaflet).

Spireblade Posted November 27, 2017 Share Posted November 27, 2017 I took my 37tts into Olivias Trains in Sheffield. They said that it couldn't be done with the Hornby decoder!! They obviously lied as I didn't buy the loco from them. There is a very useful Youtube video that fits a lighting set to this loco from Express Models. I've just ordered a set.

Spireblade Posted November 27, 2017 Share Posted November 27, 2017 I remember now, the chap at Olivias said that the lights would flicker but I have read elsewhere that it is only a CV value change to prevent it. Link to comment Share on other sites More sharing options...
96RAF Posted November 28, 2017 Share Posted November 28, 2017 With the TTS decoder having limited current for directionals lights I fitted and additional 1K resistor in the blue wire feeding the Express Lighting kit for my Class. The TTS function outputs are not self protecting and if you try to run 3 x front and 2 x rear lights each way it will overload and could be damaged.Rob Link to comment Share on other sites More sharing options...
Spireblade Posted November 28, 2017 Share Posted November 28, 2017 I'll do that when I fit mine then. Cheers Link to comment Share on other sites More sharing options...
Fishmanoz Posted November 28, 2017 Share Posted November 28, 2017 TTS decoders are 3-function - F1 white wire forward directional lights, F2 yellow wire rear directional lights and F3 green wire whatever you like but probably cab lights, blue wire common positive. maximum output from the leaflet is 150mA at 12-15 volts so Rob’s 1k resistor will limit current to 15mA max in each circuit. Enough to light the LEDs and a minimal current load. The directional lighting arrangement in the TTS is the same as most if not all decoders on the market. There should be no problem with using it.

Spireblade Posted November 28, 2017 Share Posted November 28, 2017 Just looked up 1k resistors and they seem to come in various wattages. So I get the best ones for the job which do you reccomend? Link to comment Share on other sites More sharing options...
Chrissaf Posted November 28, 2017 Share Posted November 28, 2017 When used as an LED current limiting resistor. The 1K resistor will dissipate about 100mW give or take a bit. Therefore a 1/4W resistor provides a good all round compromise. Big enough wattage rating such that it doesn't get heat stressed, but low enough wattage rating for a small physical size.
