Circuitron AR-1 question
I need help understanding the Circuitron AR-1 on a single loop track layout. I understand the train leaving the mainline going through the wye crossing over the sensor and the AR-1 switching the loop to match the main line. I can see the train crossing over the insulators and the polarity matches. I do not understand what goes on as the train starts to leave the loop and crosses over the other insulators. I would think it would short out at that point because the track come back on it's self at the wye and has reverse polarity.
Mann Made Switch machine instructions
Hi Looking for the instructions for Mann Made switch machines. Any help greatly appreciated. Thanks Geoff
Red, Yellow, Green LEDs
A few months ago there was information about a single LED with Red, Yellow and Green chips in one unit that could be used for Model railroad signals. LEDBaron ( in Germany) and Mouser no longer list them on their web sites. Does anyone know of a source? They were available both with and without leads already attached

A Longer LED Chaser
There was a discussion recently about creating a "longer LED chaser"
see: http://model-railroad-hobbyist.com/magazine/mrh2016-12-dec/arduino?page=2
I just finished up a project that will be added to the animations at Children's Hospital's G-scale layout that has 160 LEDs chasing each other's tails and I thought that some of you might be interested in how it was done.
Train Detection Circuit - stand alone
Looking for current options for a Train / Car detection circuit.
Video Experiments
Since Rick and others began posting their videos here It seemed a good idea to have a placeholder for using video in our models. My layout is far from complete and the scenery often varies from roughed in and painted to snow looking foam shapes or just plywood. Regardless, it is fun to see the railroad from a hum perspective.
Please join me and post your trials and tribulations, YouTube links and set up's for the camera(s), and how you "produced" and edited the video.
Signalling on the N&AC
My general Blog on the N&AC has some preliminary information on my signal system. I am using C/MRI with two S-MINI nodes, DCCODs, and Oregon Rails signals. I am driving all of that with JMRI Panel Pro. I am also using Digitrax DCC, but the signal system is separate and would work with any train control setup.
I think we've got plenty of room in our locomotives...
I keep thinking of how little room we have in our HO scale locomotives for DCC & sound and lights and a motor.... and then I run up against this -

Supplying Power to a Rotating Object
Good day, all - I have been experimenting with a wireless method of supplying power to a rotating object. Things like illuminated, rotating signs, turntables, and other kinetic devices sometimes need power. Traditionally we use slip rings and brushes or similar contacts.
These can be troublesome and hard to maintain.
I have come up with a way to use the circuitry that is employed to wirelessly charge a cell phone to supply several watts of DC power to a rotating device.
I have posted details (including a video) here:
