Crystal-Eyes as do-it-yourself project...

Hi SGI-fans,

since I run Indigo2 and Octane I wanted to have Crystal
Eyes for a long time. Since they are rare and expensive I 
decided to do it as a electronics project. The outcome is
a small converter board which can directly plugged onto
graphics boards of the Impact series (including Solid-, 
High- an Maximum-Impact and the Octane`s MXI, MXE, SI and 
similar options). On the other side the board has a 
small connector to accept cheap and readily available 
LCD shutter gl*****, made for the PC crap (Search eBay
for "LCD game virtual reality gl***** 3D" or similar).

The implementation uses the 12V supply from the Indigo2 
and a PIC processor generates the timing (600Hz switching
of LCD gl***** and left/right switching synchronously 
to the 3D-signal delivered by the SGI). OK, this might
be overkill, but in this way adaption to different 
shutter gl***** can be done via firmware (converter 
ist tested with "Fanatic" and "Cyber Boy". The voltage 
to the LCDs is driven by a CMOS-chip and can be adjusted
for optimum contrast.

I am willing to share the know howw if someone is 
interested (see http://www.baigar.de/electronics/SGI3D-1.0.pdf).
Additionally I have four PCBs left which I'd trade for 
some stuff - make offers. I am especially interested in 
software sup****ting the gl***** or/and a space mouse. At 
the moment I have ac3d and battalion running with the 
gl***** and powerflip with the space mouse. I'd be 
interested in a version of perfly for gl***** and space
mouse...

    Regards,

      Erik.


P.S. Older Indigo-Style graphics (Extreme) should accept 
     the converter, too. One needs a adapter cable in this
     case...
P.P.S. Of course I will share the firmware with everyone
       interested...
