    Keep in mind that I have a coin bat in mine just so i can take pictures and to test the look of the hilt...

    They sell coin bat holders at RS. But for me I just taped the wires in place and wrapped the whole bat in tape so it does not touch the hilt wall. the final wiring will not use coin bat. I plan to power from 616. Batteries will be NiMH. I'm using Panasonic cr 2032 which are almost an inch in dia.

    Cool. do you have the battery wired directly to the led or do you need a resistor?

    no resistor. A resistor is only needed if the battery pack voltage is greater than the forward voltage of the LED. In my case the LED forward voltage is between 3.2 to 3.6v since i have 3 colors. The button cell only puts out 3v. So no resistor is needed.

    Even when running a resistored setup, you get best efficiency when your battery pack gets as close to the forward voltage of the LED you are driving.

    Just hit radio shack last night and got some cheap led's. My proof of concept has been validated! I think it'll work! I'll keep u guys updated. I've got a trip to lowes tomorrow to look for parts and - if I can find what I need - may have some early design pics to post sunday to see what u think. Fingers crossed, everybody!

    Dude, this isn't the place to drop "F" bombs. Please edit your post.

    All the measurements are there. Everything says "adds x.xx inches to your saber" and all the MHS parts except for chokes, some pommels, and some blade holders are 1.45" OD. If you had a question then you could have searched the forums. What isn't in the store description can normally be found on the boards. If it isn't, you can ASK. Most members have calipers and can give you measurements.

    Language, dude. A word you used was not nice. We know you're upset, but no need for that one, here.

    What parts did you order that were too small?

    Maybe see if there's someone here that might want to buy them off of you.

    We've all made mistakes - learn from this one and press on.

    If you truly are a buddhist, you must calm yourself, re-focus your chi - "and a solution will present itself."
