Re: New N gauge roundy roundy :D

I've been working on my turntable. The plan is to use a stepper motor and a home-brew controller to make it move precisely to the right place from a single button push. Here's the motor mounting: https://i.imgur.com/2l5OSiT.jpg Here's some motion! :D https://i.imgur.com/wmHUDUz.png I still need to t...

Re: New N gauge roundy roundy :D

Do you use 1 relay per SWITCH rather than per point? If that is indeed the case I would need 22 relays for 30 points. Exactly. One relay per switch, even if that switch controls more than one point. I don't know of any commercial boards. I never looked for them because I enjoy making my own things.

Re: New N gauge roundy roundy :D

I have connected facing points to the same switch. It works fine for me. For the LEDs you can add as many as you want to the outputs of the relay, also not forgetting that I've only used one side of the relay, there is an additional side for even more options.

Re: New N gauge roundy roundy :D

I should add a disclaimer here! I'm no electronics expert or anything like that. I just experimented a bit and found something which seems to work for my application. Your mileage may vary!

Re: New N gauge roundy roundy :D

Hi End2end :) In your pictures I think you have 3 wires coming from each motor. Would it be possible to run 2 wires from the motor and attach the common return (black wire) to a common return bus wire close the the motors themselves, then just use wire to jump(er) the single incoming common return w...

Re: New N gauge roundy roundy :D

Correct, I'm not using the built-in switches. I've never been able to reliably align the seeps accurately enough in N gauge to utilise them. Instead, I have frog juicers for each frog. Either way, you're right about not relying on the point blades. :)

Re: New N gauge roundy roundy :D

Uhmm I think making them for other people is a little premature. Best to use them for a while first to be sure they're reliable :)

Re: New N gauge roundy roundy :D

If they are solenoid motors, then 3 wires is all that is used anyway. :)

I am not using any of the switching part on my SEEP motors, because it's just too small and fiddly in N. So 3 wires to each motor only. Actually that's one of the reasons I came up with this relay idea.

Re: New N gauge roundy roundy :D

The relays I use are 12v for the coils, but since the resistance is significantly higher than the point motors, most of the CDU pulse goes to the motor and not a lot goes to the relay (they're wired in parallel), so it's safe. The switching contacts on the relay are rated for high voltage and curren...

Re: New N gauge roundy roundy :D

What you describe, is exactly what I'm doing with them. Basically, there are two coils inside each relay just like the two coils on the solenoid point motors. All I do is wire them together so that the CDU pulse switches the motor and the relay at the same time. On the output side of the relay, I wi...

Sounds like you have it all under control. :) Still I thought it was worth mentioning. Just in case! :)

Re: New N gauge roundy roundy :D

Hi End2End,

Those are latching relays. They switch at the same time as the CDU pulses go to the point motors. I'm going to power the LEDs through them.

Re: St. Blazey's - My first layout - Stage 3 Building

That sounds like a neat solution.

One work of caution though. If the switch is in programming mode and you accidentally drive a drain onto it, is there enough isolation between main dcc and program dcc such that the locomotive cannot bridge the gap between them?
