At the moment this is what i am using.
Razer orbweaver modded to cherry browns, red leds, orings, custom cherry mx spacebar with a chopped down thumb section to put in the 3d mouse.
Ive been toying with bluetooth/usb dualmode with tmk firmware and a bluefruit ezkey and then maybe switching to a spacemouse wireless when thats working.
I dont get much free time to tinker with coding and electronics like i used to.
