George,

Those are all valid circuits and should work. Do your lamps light with a 1.5V battery? Perhaps they are higher voltage than you think or maybe need more current.

George,

Have you tried to light one of the Tomar units recently with a 1.5V flashlight cell to make sure the bulb is not burned out. One mistake in wiring and it is gone.

I started with the first circuit but didn’t like the marker lights blinking as it rolled around the track.

I now have 2 cabooses with the 3rd LM317T constant current circuit working as shown with the 47 ohm current setting resistor. Visibly lit with room lights on, but not overly bright in a darkened room. No blinking or obvious dimming on a moving train. Energy cap is 6,800 uFD, 16Vdc.

A similar circuit works for tail lights on a streamliner car.

My DC layout has been completely updated and converted to DCC and everything is working as advertised.  But there is a small issue.

I have a number of cabooses that have Tomar Marker Lanterns installed and these 1.5 vdc "bulb type" lanterns are powered by N sized batteries which don't last as long as one would think.  I would like to keep these lanterns as installed and power them from track power.

I'm looking for help in making a small circuit that would take DCC track power and convert it to 1.5 vdc power for the lanterns.  If you have any personal success in making such a circuit or knowledge of such, I would be grateful if you could share it with me.

I have scoured the internet for information and have actually built several suggested circuits without success.  Any suggestion, direction or advice would be appreciated.

Tomar's bulbs do not any circuitry.  It's simply a micro bulb inserted into a marker lantern housing.

Re: Constant Lighting Circuits

They must have some sort of circuitry to knock the 12DC or DCC down to 1.5V.

 

Tomar’s site was useless for information, all it says is, “Kit includes two brass marker with lens and 1.5V Lamps installed. Markers can be track or battery powered.”

Re: Constant Lighting Circuits

The first and basic recommendation is to use a 1.5 vdc battery as the power source.  You can use track power, and it does require additional circuitry that Tomar does not provide in the kit.

Re: Constant Lighting Circuits

As I've heard it said, "The third time is the charm."  I can't tell you what might have gone wrong in my first two attempts, but obviously something did.  So I started over with new/fresh components, including a new and never used set of Tomar marker lanterns, and much to my delight, using DCC track power they lit up very nicely.

This success is for the first circuit from Wiring with DCC, without the flicker free element.  I will try the second circuit once I assemble newly acquired component parts.

For everyone who replied, thank you.  The process of learning new things with the help of others is one of the best things about this hobby.

DC Circuit Breaker?

wrhastings@...
 

Our club is rebuilding their layout for DCC. As part of the electrical, we are including a 12VDC bus to power accessorie. The bus is powered by a regulated power supply, capable of outputting 4amps. We would like to install some circuit protection, preferably an auto resetting breaker. Do any of you have a recommendation on what we should use?


Bill Hastings

Re: DC Circuit Breaker?

jazzmanlj
 

If the power supply is regulated it probably has over current protection. In most designs the regulator either folds back or shuts down and recovers when the current burden is lifted.


Len Jaskiewicz

Re: DC Circuit Breaker?

Ross Kudlick
 

Bill,

 

Our club has a similar bus.  I’ve “branched” the bus using 1 amp circuit breakers.  Each device is then connected through an appropriate  Raychem Polyswitch “resettable fuse.”  Here’s a link to the DigiKey catalog:

http://tinyurl.com/mkas5qb

 

What accessories do you anticipate powering from this Accessory Bus?

Re: DC Circuit Breaker?

Vollrath, Don <dvollrath@...>
 

Ross has a good idea. The Polyswitch type resettable fuse devices work well to protect wiring and other devices from long term overcurrent damage. For example they work great to protect twin coil switch machines from folks who like to keep the button pressed way to long. But they do not operate nearly fast enough to protect semiconductor circuits from high peak over current. However, they do have some internal (cold) resistance that tends to limit the peak short circuit current. Read the technical data sheets to find the best device p/n for your application. Several brands of competitive products exist. The DigiKey catalog (or google) is a good place to start. Having several ‘branch’ circuits each with its own Polyswitch fuse and a simple disconnecting toggle switch for servicing might be a less expensive way to go. You could put a miniature 12-14V grain-of-wheat lamp in parallel with the Polyswitch if you really want to know when/if the Polyswitch is limiting current. Be sure to mount the Polyswitch(es) in free air for best results. They do get hot when ‘tripped’.

Thanks for the replies. At this point, we are going to be powering Tortoises and accessory lighting (buildings and street lamps, etc.).

If the supplies are rated at 4 amps, what trip current should I be looking at, for Polyswitches?

Thanks, again

Address management for DCC device addresses

Gregory Latiak
 

I am just finishing up the physical wiring of my small Digitrax layout and am in the process of design/build for a control panel and signalling scheme. It hit me, while contemplating the rules for the signal addresses, that my layout is starting to look very much like a primitive network, like the early days of the Internet when one maintained and edited name/network address lists. Only with DCC there appears to be no management layer for the addresses or any logical name scheme either. But plenty of vendor-specific rules about address blocks and relationships.


While I recognize that for something like JMRI or Trainmaster to function all the addresses must be collected and embedded in its configuration. I refer of course to locos, stationary decoders for turnouts and other device control, signal systems and so forth.


Any software tools out there to help beyond yet another spreadsheet?


Thanks,


Greg Latiak

Re: Address management for DCC device addresses

Vollrath, Don <dvollrath@...>
 

Greg,

Like the original railroads, it is up to the builder/user to keep it all straight. Organized documentation becomes more important with growth and changes. Since my personal RR has outlasted several versions of PCs, program apps and decoders I still use a master layout drawing showing all turnout and signal locations with their assigned addresses. Then there is also a master list of turnout, loco and signaling equipment addresses on an Excel spreadsheet with a back-up e-file and paper copy secured away for redundancy. Each turnout, loco and signaling device must have a unique address. Simply checking and updating the listings avoids duplication when changes or additions are made. Unfortunately all manufacturers seem to have their own way to make things work.

I use DecoderPro to manipulate and hold all decoder programming, including macros for an NCE command station.

I also use a spiral notebook or two to document ideas, sketches and notes in chronological order so that I can refer to them later. Having it all together in a notebook keeps key information together and organized. Pencils and pens still work.

Len, what sort of examples are you looking for?  Over the last two years I seem to have been through almost every oddity and glitch that can happen when wiring a large layout.  It all comes together eventually, and it isn't a bad experience per se, but there is a lot of learning.

Hi Jerry,

It would be of benefit as to see how some people correlate physical names of stationery devices such as turnouts, signals and other devices to numeric addresses. I have a few ideas as to simplify it so one doesn't have to have pages of printed sheets in hand.

Seeing printed examples of other peoples could be of benefit.
