Which software do you use?

As to the FastLED lib, at least the FX-SaberOS developer community decided against it due to it being quite storage space intensive, as opposed to the one currently used. With all the latest improvements in the Arduino IDE it could just be that we can accommodate now the FastLED lib, so feel free to experiment and let us know the results.

As to freeze, in my experience it's always because the board has a memory overflow.

I'll let you know.

Do you think removing jukebox related features can free up some space to avoid memory overflow?

We already freed up in preparation for the FX-SaberOS v1 a lot of dynamic memory by restructuring sound font handling. Jukebox does not eat up any memory, and anyway it can be disabled by simply disabling the compile option.

BTW, I would like to suggest to move open source software questions to GitHub and steer back to the original purpose of this thread: to discuss neopixel blade topics.

I've been experimenting a bit with neopixel sabers over the last couple of weeks (made MUCH easier by the DIYino Stardust and FX-Saber OS).

Been starting with various premade blades I got from a grabbag and a Corvin style blade from TCSS - a thicker layer of diffuser film definitely helps I think on removing the visible LED segments, and the foam works to some extent...

But I'm curious what JBKuma said about wrapping it with TP or some other form of thin paper. I've tried it a couple times and the TP just tends to fall to pieces as I try to put it into the blade tube.

It's not practical in any way. It will be almost impossible to get a seam that doesn't have ugly gaps and overlap.

I got really good results on my neopixel blades with the following:

7/8 thin-walled clear blade and tip
TCSS diffuser tube for 1 inch thick-wall blades (same ID as 7/8 thin wall)
3 feet of craft wrap
6 inches of 1/32 packing foam.
2x 'skinny' SK6812 strips (8mm wide, 144 LED/M)

Measure out the strips to ensure they're cut to length to fit the blade length you're going for.
So, put the strips back to back and use clear packing tape to attach the strips to the foam.  This helps in making the foam wraps nice and tight.  Secure the ends of the foam with clear packing tape.
Put the diffuser tube in the blade (it'll be snug, but moving slowly and with a piece of scrap to help, you can tap it in.)
Drill out the tip so two strips will fit into the tip (remove the mirror, of course)
Roll up the craft wrap and insert into the diffused blade
slide the foam-wrapped strips into the blade, ensuring that they go right up to the drilled-out tip.

This combo results in a bright and even blade that doesn't have any shadows or corncobbing.
