NIce. Thanks for sharing. Did you coat the visor?

I sprayed it with AESUB blue. Not the perfect spray - i smells and it actually leaves
a bit of traces after "vanishing".

I will continue to use it, but maybe not to everything :-)

Great scan. What calibration chart was used (as I understand it, this is a real, full-sized helmet scanned)?

Yes, real helmet. I used the 240mm calibration panel for the first time. RMS numbers below 0,1 (!)

2x IS-cameras with computar 12mm, Optoma ML750, and "IKEA manual turnatable". As usual :-)

Great! I usually have RMS in the range 0.5 - 1.3 on tables from 30mm to 80mm :D

How did you manage to use 2xIS camera? When i try to connect one always freezes. What model do you use?
Thanks in advance!

I use this one:

I would say that you have a USB-problem. I struggled a lot with this (actually with the Oculus Rift VR-goggles).

I use USB card Inateck PCI-e to USB 3.0 (4 Ports)
The big thing for me was to set the correct PCIe-generation manually in BIOS. I have Gen3 on my Motherboard and the card is a Gen 2 (?).
This gives me steady 54fps on both cameras.

My Asus laptop works almost as good out of the box but i keep proj/camera cables apart as much as possible.
