That schematic is really really helpful. It has information that I haven't seen before. Thank you.

Have we verified if Roy's kobold clip fits on the 2.0? I'm about to order the TFA gold card and a clip - I don't mind the red button being metal/anodized, but I want the rest to be fairly accurate. (I also don't mind not having a graflex logo, idealized is cool too).
It should fit just fine. I think the sizing should be the same but I hear the one on the 2.0 kit is a little more plastic/chrome feeling while Roy's looks more screen accurate.... I have not seen either first hand....

For blue LEDs from TCSS like on this here ti cree... http://www.thecustomsabershop.com/BlueBlueWhite-Cree-XP-E2-CopperNova-P1013.aspx
The LED calculators all show 1 ohm 1/4 W or am i putting something in wrong somewhere? The 18650 for use on the NBv3 has 3.7V do you use a different number for the calculations?

Might order one of the Kobold's from Roy, but just for now, I took the one that came with the 2.0, sanded it down and brushed on some matte varnish.
And yea, I know I need to redo the foil tape I placed on the bottom, lol.

I like the brushed look.
Haha... Sorry, I was just about to remark on the aluminum tape.

I love this tape you can use it on anything to make it look metal, it is the tape they use on duct work rite. Yes this this stuff really sticks to anything and stays stuck now you can scrape it off and you can kinda peel it but its good stuff. And your d-ring looks great! Thanks.....Jim
These are the specs from the TCSS product page:
Blue Cree Part# XPEBBL-L1-0000-00301
45.7 Minimum Luminous Flux @ 350mA
Forward Voltage @1000mA = 3.47v
The calculator found here: http://led.linear1.org/1led.wiz asks for a source voltage, which as you said, is 3.7v. Next it asks for the Forward Voltage of the diode, which according to the spec sheet the average VF of a blue diode is 3.47v. Next it wants the Forward Current as read in mA, which according to the spec sheet is 1000mA (1A). Disregard the 350mA, that is not the value you want to use. If you enter the correct values into the calculator you get a recommended resistor value of 1ohm 2watt. Now since each diode requires this resistor it is recommended each one gets it's own, otherwise you're splitting the value of the resistor between the two. Hope this helps ^_^

No that helps a lot I was going off the 350 number

These are on ebay, forward volt 2.0- 3.0 pre wired with resistor 20ma this is what I'm using on the nano biscotte crystal focus v7.5 crystal chamber reveal they come in lots though but not priced to bad. any color you need. Can't wait to get started. Thanks .......Jim

I got my tri-rebel blue/blue/white and lens today. Now I have a question. What guage wire, and what resistors (and does each light get one), and battery and recharge port type? I'm using the Goth3D Knight chassis (still waiting delivery) and the NB V3 soundboard as well.
This is my first saber build, so these probably won't be my last questions. And thanks!

These YouTube videos from TCSS should help:

You want to use 28-32 gauge wire and a 3.7v battery. You can calculate the resistor values using a LED calculator online by using the given forward voltage of the LED on the TCSS website (assuming that is where you purchased them from). If you have any more questions, feel free to ask them.

here to piggy back, if you get the V3 nano biscotte....they dont use a PEX(power extender) its built in

For anyone that hasn't seen it, here is a basic wiring diagram I drew up for the Graflex 2.0. It uses a NBv3, an 18650 3.7v battery + recharge port, B/B/W Tri Cree and is laid out in the same orientation as it would be if it were in a Goth 3Designs "Knight" chassis. I have others as well for the NBv2 with PEx and many that use different configurations for wiring a multitude of Crystal Chamber accent LED's. Hope this helps ^_^

That'll help...the recharge port addition will help...I've ordered the 1ohm 1w resistors now...
And if I have some 3.1v LEDs for the crystal chamber that I want to light when the saber is on...and the manual says that's 3.3v would 15ohm 1/4w resistors be appropriate for two LEDs on that circuit?

Thanks for those links, they are helping. Though now I have hit a brick wall it seems. I've been trying to figure out what resistors I need for the Tri-Rebel (blue/blue/white) from TCSS, but I can't seem to find the "diode forwarding voltage" to enter into the LED calculator to save my life.
