Purple blade

[imagehunter]

Hi guys, hoping to get some input from someone who might have experimented already. To get a purple blade, which option is best?: A red LED with a blue filter disk, or a blue LED with a red one? I don't want to do a red and blue LED together because I read they need different power requirements and with my vast knowledge of electronics, I'd have an easier time lifting an X-wing out of a swamp with my mind.

If you're determined to do it that way, I'd imagine you'd be happier with a blue blade and red disk but I don't know of anybody using that method to get purple. If I had any color discs I would go ahead and experiment for you but I don't. Sorry.

Helping people understand the electronics of a saber is what this forum is all about. If you tell us your setup we can probably help you out so that you can get a true purple. (I would go blue with red filter because with a blue filter you are going to lose some brightness)

True the LEDs do need different power requirements, but that just means two different resistors (One for each LED) with the LEDs wired in parallel. If you have a Sound Board you can use a color extender to provide proper color mixing.

If you're determined to use filters, then you need a White LED with red and blue filters (or a purple filter).

The red LEDs only put out red wavelengths of light. If you put a blue filter on red light, you get very little light at all. Same goes for the reverse.

Wiring a Red and Blue multidie LED in parallel is the best option for purple. Read around on the forums, you'll find some diagrams. We'll be glad to help out with any details.

Just a quick heads up but we are doing a trial run of trans purple tubes that should be here next week.

I used a tricree ep2 with one red and one blue. Ran in parallel with proper resistors. It's still currently in the WIP stage, just need to get it all wired to my NB2. I read elsewhere that if you want to adjust the color, you can experiment with resistors with different Ohm values to change the shades.

Good luck!

Thanks for the input guys, looks like I need to do a re-think on my blade design. Strydur, I'll be waiting too see how your trials turn out.

Proper color mixing requires which sound card? I was looking for a Mace Windu purple. I was looking at Nano Biscotte Sound Module V2. Is this card enough to do proper color mixing? I tried the white LED with filters and that doesn't look good. So the Tri-Cree for the best purple is blue, red and white, correct?

Proper card for easy color mixing is either the Prizm, Petit Crouton, or Crystal Focus. You can color mix with the Nano by varying resistors, but the others you can control with Rice straight off the board or with the color extender.

I think most people use a combination of RoyalBlue and Red when trying to mix a good purple, versus the regular blue

You don't want to use white in your mix for purple. It will wash out both leds, making a pastel purple.
