ANy more details eigyro? Is the kit available 'packaged'? What is the cost?

 

Embedding your work in my DeD's Gorgeous

If I could a complete set would be the top of my list....Stunning

[eigyro]

The price is 20 euros + actual postage cost. Currently I have 6 kits in stock. All are pre-tested, i.e. the LED strip and the rectifier module are checked for correct operation.

 

Here is a picture of the packaging. I will try and put the installation instructions on this thread this evening so folks can see the process and figure out if it looks

like a runner.

And install guide would be excellent i've lots of MK3's that would really come to life lit like that!

eigyro, that craven look's the business, well done,

[eigyro]

Separate the coach body, seating insert and chassis.

 

You may need to limit the travel of the bogie to prevent it from turning around enough to cross the wires.

The insulation on the Litz contact wire is wrapped silk, which allows great flexibility at some cost to durability, so it

is advisable to route wiring so as to avoid crossovers, especially where movement/chafing is an issue.

 

The method I use is to drill a small hole through the bogie and chassis, for the limit pin which is fixed in the chassis. Drill a larger hole in the bogie only, concentric with the pin hole. This hole should be made large enough to allow adequate turning radius.

See photo below

[eigyro]

Drill one wire hole each side of the bogie pivot pin, through both the bogie and chassis, for the pickup wires. The holes must be wide enough to allow the passage of the wires without 'scissoring' the wires at the max turn angle. The nearer the hole is to the pivot pin, the smaller it will need to be.

 

See photos;

[eigyro]

Feed the free end of a pickup wire up through one bogie, along the top of the chassis and down through the corresponding hole at the other end. Glue the attached pickup in place, bending the contacts slightly towards the inner wheel.

 

 

Below is a suggested method for soldering the free end of the wire to the other contact. This keeps solder from getting under the contact and spoiling the contact patch, which might interfere with the fit onto the bogie.

 

[eigyro]

With the wires hooked up and contacts glued in place, it should look like the following photos;

The wires should be gathered as in the next photo;

 

 

Note the tape holding the wiring gently in place. The loose wire should be gathered and twisted as above. The tip of each gathered end must be 'tinned' with solder.

 

With Litz wire, you should lay the wire on a small piece of wood, place the soldering iron, with some solder on it, on top of the wire end, and 'drag' the wire out from under the iron. This removes the silk insulation and allows the solder to 'take'.

 

That completes the chassis.

[eigyro]

Install the lights in the coach roof. Peel off the protective strip, and fit in place. The adhesive is very forgiving, so don't worry if you have to re-position the strip. See below, and make allowance, if necessary, for bulkheads, toilets etc., in the

insert.

 

 

Drill two wire holes up through the seating insert at the place you wish to site the rectifier module. Don't feed both wires up through a single hole. The holes should be positioned so as to meet the two free ends of the diodes as shown below;

 

Draw the two wire ends up through the holes. Solder one wire to each diode. It doesn't matter which wire to which diode,

just try to avoid crossovers. Position the module in place, drawing the slack wire back down through the hole to be coiled neatly underneath, keeping the two coils separate.

 

[eigyro]

Fit the seat insert back on the chassis.

 

Drill a 3 or 4mm hole through the insert and chassis so the brightness adjuster screw is accessible from underneath using a jeweller's screwdriver. Mount the pot (potentiometer- the blue brightness adjuster) so that the adjuster screw sits in the hole, ideally centrally.

 

 

Now for the final connections;

 

The negative wire from the LED strip in the coach roof is the one nearest the little black component at the end of the strip.

It must be soldered to the negative side of the rectifier module, which can be identified by the broad white strip down the side of the brown tubular component.

 

 

It should look like this;

 

[eigyro]

Next, the positive lead from the LED strip, identified by a knot tied in the wire, must be soldered to one connector on the blue pot. It doesn't matter which one.

 

Finally, the small piece of unattached wire, is soldered, one end to the second connector on the blue pot, and the other end to the positive side of the rectifier module.

 

It should look like this;

 

[eigyro]

Or, more clearly, I hope, like this;

 

 

It is a good idea to test the installation at this point, so as to avoid having to pull it apart later.

 

Make sure at least two of the eight wheel contacts are actually touching the inside of their respective wheels.

Lay the chassis on the track, with the coach roof to one side.

 

If all is ok, you should see this;

 

 

I hope these instructions are clear enough. At least they should provide enough information to the builder to decide whether the job is within their skillset or not.

 

Electrically, the worst you can do is cause a short on your track, which DCC systems are well protected against.

If you get the LED connections backwards, it just won't light, but you won't damage the LEDs.

As with all such projects, you are wearing safety glasses, aren't you.?

 

The kit is part-assembled to prevent polarity issues with the smoother/keep-alive capacitor, and bring it within the

skillset of more people.

 

This is what the demonstration sample looks like on track;

 

 

That's all, folks. Comments are welcomed, good or bad.

[Kirley]

Excellent guide, well described and illustrated.

[BosKonay]

Great clear instructions, and I can testify as to the great warm, accurate lighting, and the absolutely rock-solid lighting itself (no flicker, no issues!)

Now, where's me soldering iron?
