It is done. I think I am finally finished with this saber. I will probably keep adding small stuff but for electronics i have had enough.
Here is what has been done.
Added a half chassis so the bars in in front of the crystal chamber are now solid in place.
I still used the Ultrasabers battery pack which is now loose enough to be able to replace the batteries.
Remade the control box out of some plastic t-bars and sheet polystyrene.
Added a crystal chamber.
Deactivated the horribly annoying motion sensor. (i am perfectly happy with clashes and the idle hum)
Extended the saber a bit with a raised pommel and a new pommel cap.
Moved the blade retention screw up a bit.
Rewired the entire soundboard.
And had lunch in between this all.
Of course i have new pics for you. So please enjoy the improved Starkiller

May the Force be with you
