It makes a long time since I last updated this thread so here are some news.
I started drawing the inner parts, for a fully functionnal inner chassis, featuring fully hidden electronics, breakable and assemblable out of the saber frame.
It will include self charging energy cell, crystal chamber with settable fins and focusing lens, and motorised cyclic filed with rotating gravity channel.
I will also design the inner parts of the emitter, so it will be possible to use as a collet chuck, like I designed it back in 2013
For now here is a first cell design attempt, it will be modified to get more room and more details too.
The electronics will be a 18650 battery, maybe a pico light board or a nano biscotte, I have the pico, maybe I will use it, far easier to hide due to it's small size.
Regarding emitter, I made some detailling and weathering.
