I did do a build log for this, but thought pictures in the Gallery would be good as well.
I built this based on the picutures of the lightsabers that Starkiller used in the promo for Force Unleashed 2.
Its all MHS parts, a Blue Seoul P4 LED, 7.4 lit-ion battery pack (18650, from TCSS) and for sound a Novasound 3.0 dark
I replaced the grip tape with leather...l-e-a-t-h-e-r!
Thats pretty much the extent of my editing
