Re: Need help with a plan-OO gauge

With two tracks in parallel you can run two trains at the same time. Just a thought. The design has several places where two trains can pass each other. A single line layout with a few passing loops and sidings can provide more operational interest, as long as you're not an obsessive collector of n...

Re: Need help with a plan-OO gauge

Are you using Hornby set track? I see you have used a couple of flex tracks in there. I'm having a devil of a time to make it work in set track only.

Do you mean Sprog 2 and Sprog 3?

Hi Dan,
I think these wire up the same as any live frog turnout, using a combination of switches and insulated joiners. A quick search of the forum finds,

Re: Fading motor...

but it could also indicate a magnet that has lost its magnetism. The motor would draw more current.

Re: Am i doing this LED work correct?

Ok so, from what I can gather the DB107 rectifier has a reverse recovery time of 500ns which is referred to as "standard recovery time". I'm not sure how to calculate the max frequency vs the Trr, especially since we're talking about a square wave here instead of a sine wave. But I would n...

Re: Am i doing this LED work correct?

I couldn't find any Schmitt trigger diodes or rectifiers when i was searching. Do you mean Schottky?
I believe Dcc is 10KHz.

They look great.

Re: Am i doing this LED work correct?

As said by Ironduke, a bridge rectifier greater than 40mA is needed so anything above that will do. (i.e. 100mA or 0.5mA) [Technically it should be a Schmitt type] If a big electrolytic cap is included then you need to account for a short burst of higher current when it first charges up but most re...

Re: Am i doing this LED work correct?

The rectifier is huge. You don't need anything like 3A just for LEDs. Nothing wrong with that if you have room in your carriage but, if you need something smaller, a small DIP package with a forward current of maybe 1A would be ample. Say a DF04M or similar https://au.element14.com/productimages/sta...
