Anybody done this yet in an O-scale car?  If so, what was the length of the car, size of battery,  where did you locate the battery, on/off switch?

How many LEDs did you use?  Can you post the circuit diagram?

Most of the "kits" I've seen are for 3-rail cars converting AC to DC.

Adafruit has a lot of different LED offerings, but some of them seem to need inputs from an Arduino or something similar.

Hi Bob,

No details I'm afraid but here are some for OO that use lithium batteries, and motion sensors to switch on. May be helpful, or a source of ideas.

Use LED flexi stripLeds (just use 3 on a piece of strip) and a 9v PP3 battery/on off switch..Minimum voltage 6v...max 12v.

Thanks guys! The strip LEDs are the ones I've been looking at, should make for an easy install.

Please help "enlighten" an unlighted rookie. I have searched "strips" and I can't find anything but rolls. Not a 3 light strip out there that I can find. Do you cut the roll down and solder this back together? Or is there a product that I can readily adapt?

Thanks!

Anyone know what the number of the chip (I assume) and motion sensor is that Train Tec uses to turn on and off the lights?

Hello,
You can purchase the white, 12 volt rolls of LED's on Amazon for about $10.

http://www.amazon.com/Triangle-Bulbs-T93007-Waterproof-Flexible/dp/B005EHHLD8/ref=sr_1_1?ie=UTF8&qid=1451333295&sr=8-1&keywords=12+volt+led+strip+lights

The flexible, self adhesive LED strips are designed to be cut in segments of 3 and powered with up to 14 volts. The best part of the flexible strips is that you can tint the light using indelible markers. If you think the light is too cool, add yellow, orange or red. If they are too bright, use lower voltage or a gray or black marker. I use them with 11.1 volt Lithium-polymer or Lithium-ion batteries, depending on the scale.
Hope this helps,

Don

But I was wondering about the light control system that they use. I have had the rolls of lights for a couple years.

Herb,

I don't know but I bet it's the same sensor they use in their tiny sound device:

Train Tech Sound

Unfortunately, there's no US dealer from what they told me in the email I got a few months back.

Look on eBay.... They come in just about any colour but I find the warm white run at around 7.5v from 2 18650 lithium cells to be really very good and produce a nice Incandesecent glow.

I ordered some led strips from Adafruit last week and should get them in Tuesday.
If they work I'll post what and how's.

I installed two lots of three strip lights (amber)...in a coach and used a 9v battery (PP3) and a press on/press off switch through the floor of the car. No probs..nice light.

Here's the fabric LED strip I ordered:

LITEX LED STRIP

I ordered a couple plus some of the battery holders so I can cut these in half and get 2 cars worth out of each.

I figured the fabric strip would be easier to handle and small enough it won't be seen.  The battery holder/on-off switch is small enough I can mount it under the floor and not be seen, or paint it a color so it will blend in.

Got the fabric LED strips in yesterday.  I quickly installed a piece inside one of my cars.  1st I cut the cloth strip to the length I wanted (with another on/off/battery holder the rest can be used in another car) and mounted it onto a length of double-sided Scotch tape.  Here's a photo (in another car):



On the car I installed it in, I simply placed the battery/on/off box inside the end of the car:



I made the end of this car a snug fit to make it removable, the coupler pocket lip helps keep it in place:



Push the button and we have lights:



SAY WHAT?!?!?!  I think they sent me the wrong string, sure looks blue to me :shocked:

I still think placing the "control" box on the underframe is the way to go, just need to drill a strategically placed hole, although it may be possible to run the cloth between the underframe and body without drilling.

I have another string of LEDs so I'm going to see if they're blue also, hope not.

To me eyes it doesn't look that blue looking at it in front of me but the camera sure picks the blue up well :us:

My other passenger cars don't have a removable end so I need to determine how I'll get to everything.

All 3 packs of the LEDs I got say "WHITE" on them and they do look white outside the car. I'm thinking the blue is a reflection of the blue seats I have inside the aluminum walled car. Unsure what to do about that except maybe paint the inside walls white.

Adafruit does offer them in other colors including yellow.

BobD.

PS...Seaboard did put white covers on the back of the headrests, maybe I'll add that little touch and see if it cuts down on the bluish tint :thumb:

Touch up the led bulbs with a yellow felt tip marker?

Thanks Herb, I'll give it a go.

I found I can pop the end out and turn the LEDs on/off without having to pick the car up off the tracks. Still want to put the box underneath, but other projects are in the cue.

The removable end is a neat trick Bob.
Remember the camera interprets colour depending on the combination of real and artificial lighting types.Playing with the camera's settings for light source might help reduce the blue in your photos too. The main thing is how it looks in real life.

Bob, it definitely doesn't look that blue in person and outside the car they look white.

1 spool is enough for two 21" cars.

These cloth ribbon LED strings may be good for buildings too. You'll have to be prepared to buy more batteries, or design something that can be charged.

What type of battery is in the box Bob?

There's 2 CR1220 batteries in the box.

They're 3v Lithium and sell for under $1 US each.

The push button has 5 settings: solid on, fast blink, slow blink, fast fade, slow fade. All the components seem well built.

The one issue I thought of is...can these be placed on a metal surface without shorting out? I have the double-sided tape in between the cloth "wire" and the aluminum body, maybe I need to email them and ask.

I'll guess they run them in series to give 6V. At that price might not be worthwhile making up a rechargeable pack.

I think you're right Bob on them being in series.

I don't run my passenger cars often, if I could ever clear out the rest of upstairs I'd more than double the length of the mainline, THEN they stretch their legs :old dude:

I need to buy some sitting-down peeps to populate a couple of my cars. I'm always seeing a bag of 50 to 100 on ebay, but don't know about the quality. I believe they come from China.

I would buy one of those 50 packs of little people.  Don't worry about quality because other than their head in the window, they really wont be seen.

Good thinking Dave [toast].

If I can avoid painting "Google Eyes" on them I'll be alright. There ought to be decals for 1/48 scale eyes :brill:

I have a pack of 100 for populating carriages etc. Good value and more than detailed enough for that use.
They can also be improved with more painting of the face if needed for ones that might get closer inspection.
