1000Hz polling and lsight prediction with 900 dpi.
noticed some irregularities with the interval between pollings, cheap ass mcu, couldnt find info about it besides that team scorpion also use it.
this might be an otp mcu (so no firmware updates possible).
red led, lens and clip dont seem to be original avago bundle.
mousefeet in the back are double layer (->ME failure).
there is a removeable wight in the ack, estimate to be 10gr.
cable is unfortunatels soldered and SR looks like a weak design.
cable a little stiff.
buttons are all omron, but feel not so great (again ME failure, friction inside).
left and right click have noticeable difference in operating force.

waste of time to assemble back together for tracking pictures if u ask me...

It has real omrons and a pricier 3090, but the PCB - layout, tooling, and wiring look atrocious.

Would be quite ironic and hilarious if this mouse didn't show any tracking flaws. If I could recall, the firmware uploaded had a fairly decent max speed at 1800 cpi.

... assembled back together for skylit.1800cpi on Zowie G-TF is 2.4-2.9m/s according to enotus.
counter is 127 every time. some minor jittering, a little worse than usual.

i have to ask, what does the max counter represent.

so far I have seen only one mouse (that i tried personally) to go above 127.

if i got it correctly: accumulated movement data, if it is (2^n)-1 very likely an overflow, meaning mcu limits max possible speed.
post #20 of 43
if this is correct (which i assume it is), it explains alot. however, it still makes me wonder why would logitech put weak mcu in g400, compared to my (very old) a4tech mouse.
