one more small note. I had stated some while back that I would hope the cutouts in the plate were large enough to remove the PCB-mount stabs although assembled - now I know why this is such a difficult thing. once it's built you can't get them out. just like with all other plates for PCB stabs. I think I know now what I would have to change but this is something for another project.
so like always with pcb stabs: make sure you get them lubed and perfect before you put everything together
the steel plate is supersolid btw. probably due to the big surface area around the side of the plate. especially I am super happy with the feeling vs the aluminium plate that I have in the prototype (65%). with every bottom out the alu plate reflected vibration back into my fingers, just very slightly but still noticeable. not so with the steel plates now, absolutely enjoy typing on it.
also, yes, soundtest/typingdemo still coming. got the mount for my phone yesterday.
damn, preparing everything for the GB takes so much time! hope I can start it by sunday.
