<![CDATA[Latest posts for the thread "Using LED tor internal lighting on Valkyrie"]]> http://www.dakkadakka.com/dakkaforum/posts/list/8.page JForum - http://www.jforum.net Using LED tor internal lighting on Valkyrie
I have a 1.8mm LED that I want to put in.
1) Do I need a resistor?
2) If I do, what size does it need to be?
3) What size battery would I need to put in?
4) What switch should I use and where can I purchase it?

The specs on the LED are as follows:

Red LED (want it to be the low vis lighting you would see inside the transport running at night for spec ops missions).
Clear Lens
Forward Voltage (V) : 2.0 ~ 2.2
7000mcd

Any help from you Veteran modelers out there would be most appreciated]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364555.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364555.page GMT Re:Using LED tor internal lighting on Valkyrie You won't need a resistor, I used a small 3v battery

About switches I think you might need to order one of the internet or maybe your local hard wear store]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364755.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364755.page GMT Re:Using LED tor internal lighting on Valkyrie
The amperage on the red leds(2.0-2.2v) is slightly smaller than most leds of diffrent colors that won't need them(3v-white, clear, blue, green,...). If you use a higher voltage on the red ones you will most likely burn it out. I don't remember the size right now but research it before you hook it up.

There are a tons of listings on battery holders and watch batteries on Ebay. Some include switches and some don't. I use this place for my swithes. http://www.miniatronics.com/Merchant2/merchant.mvc They also have other led lighting effects too.

A coin(watch) battery will be a fine power source as long as it's at least 3v.

Remember that leds have a positive and negative sides to them. They won't light up if they are hooked up wrong. The black or - side of the led will have a flat area on the side of the dome of the led. That is where your negative goes. The other will go to red.

I hope some of this helps.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364822.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364822.page GMT Re:Using LED tor internal lighting on Valkyrie http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364836.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364836.page GMT Using LED tor internal lighting on Valkyrie this one (merely the first result in a Google search - I've seen others recommended in the past) - they'll tell you what resistors you'll need, if any, based on your particular power source, LED voltage ratings, etc.

As far as parts are concerned - switches, battery holders, etc. - there's a RadioShack reasonably close to most areas if you need a part quickly or find shipping costs prohibitive, but they charge a significant premium that makes ordering online much cheaper, part for part.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364984.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5364984.page GMT Re:Using LED tor internal lighting on Valkyrie
I know there are a few people out there that sell ready made LED kits for some GW models.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5365078.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5365078.page GMT Re:Using LED tor internal lighting on Valkyrie

There's no resistor in here and it works fine


While it may work it's not going to last as long as an LED wired with a resistor would. It will eventually burn itself out.

If you don't know what your doing just order a pre wired LED off the internet, and a simple catching switch will work.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5365139.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5365139.page GMT Re:Using LED tor internal lighting on Valkyrie http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5365387.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5365387.page GMT Re:Using LED tor internal lighting on Valkyrie
I have a tutorial posted in the "how to" section on lighting up a chaos lord, and in it I use a 5k MCD red light with fiber optics lighting up his eyes. That should give you an idea of what you are looking at. Most of my red eyes are 5k MCD and they work pretty well. Bright enough to see in normal indoor lighting, yet not overpowering and too distracting.

On a side note, one of my first projects was a rhino with white head lights. not sure what the MCD rating on those bad boys was because I scavaged them out of a flash light, however, the guys I play against at my FLGS have banned me from turning on the head lights during a game because it is blinding and makes for a major distraction when playing.

As for recomendations on size, I suggest 3mm as a good standard. The only way to go smaller is to use surface mount leds (which are a royal pain in the ass to work with) or set your led somewhere else and use fiber optics to 'pipe' the light where you want it, and the next size up, 5mm, is about the size of a headlight in the 40k world. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5366556.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5366556.page GMT Re:Using LED tor internal lighting on Valkyrie
Also thanks for the size input. I have ordered my LEDs. I'll do my step by step as I paint, build and light up my Valkyrie!

Thanks all!]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5367585.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5367585.page GMT Using LED tor internal lighting on Valkyrie Two reds for the turbine exhausts (5mm) and a two greens (3mm) in the cockpit. Batteries go under the top of one of the engine nacelles (which is magnetised to hold it on) and the switch goes under the "hump" on top between the nacelles.

Wiring runs from the cockpit into the main compartment and up the front wall (hidden behind a partition, where it could be run to the switch and batteries).

I used to do this stuff for a hobby before I started gaming (started soldering at the age of 12, started gaming at 17. I'm now 44). If pressed, I could design and produce a circuitboard for the job, but a job this simple doesn't require it.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5369240.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5369240.page GMT Using LED tor internal lighting on Valkyrie http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5370243.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5370243.page GMT Re:Using LED tor internal lighting on Valkyrie ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5391256.page http://www.dakkadakka.com/dakkaforum/posts/preList/512497/5391256.page GMT
