    Portabel VR Rig

    Thanks! The screen is an ELO 1502L (15.6" 1920x1080 touchscreen). Expensive for a "meh" monitor (~$700 CAD) but well built and available in quantities of one.

    Portabel VR Rig

    Hey all, Made a post a while back talking about a portable VR setup we were working on for a client. Thought there may be some interest here now that its built (and again thanks for the suggestions re CPU and GPU). Specs: -i7 8700K -Mini ITX Asus Z390-i -RTX 2080 (ZOTAC Blower Style) -Samsung 970PRO SSD -15" touchscreen -500W 1U PSU -Built into a Pelican 1510 (carry-on) System goes from zero (latches closed) to hero (in game) in under 60 seconds. Cooling is accomplished by two 70mm PWM Deltas (push/pull) with air-pathing for a cold---> hot section. In VR the fans don't really throttle up much, in bench marking they do make some noise, however do NOT go to full throttle (at least at ambient Victoria weather) All components are affixed to a floating 1/8" aluminum plate with CNC mounts for tie downs. The plate is left floating for impact and vibration isolation (closed cell foam all around the plate). All components are then sandwiched to the floating plate through a thermally conductive gel isolation pad to both give added vibration isolation and so components such as the MB can shed heat from the rear of the PCB into the plate (which has cold air channeled over it.) There is then a plexi "false floor" that is stood off from the pelican case to again sandwiched all the components (and the aluminum plate) down. Additional foam is held under compression to help dampen against impact. Plexi was chosen mainly to smooth airport security.
  3. Hey all, Working on a funny build and wanted a second opinion before pulling the trigger on some hardware. I have a client that needs some pretty high end hardware installed into the bottom of a pelican case to deploy a VR training solution that allows rapid setup/tear-down by a non technical person. The idea is basically to have a false bottom where all the hardware lives to leave an open void for stowage of the headset/wands/keyboard (and some of our proprietary gear), then have a touchscreen mounted in the lid. The client currently uses Oculus hardware so we will also be mounting the sensors in the lid as well. The unit needs to be able to survive rough handling, sub zero storage, etc. These are being designed/fabricated for an industrial client so reliability and performance are more important than cost. Pretty sure I have the mechanical side figured out at this point (we are an engineering shop) but I wanted to vet my hardware choices. Current plan is to go with: Asus Z370-I (ITX) I9-9900K (we need very high single core performance, the simulation software it will be running has very heavy single core loads) Samsung 970 Pro M.2 Asus RTX 2080Ti (blower style) mounted flat Via riser cables Dyantron K199 1U cooler (good to 95W TDB) G-Skill 16GB (2x8GB) DDR4-4266 iStarUSA TC-1U70PD8 700W (1U PSU) Integrated monitor: ELO 1502L (15.6" 1920x1080 touchscreen) Anyone see any major issues here? Thanks!
  4. Hey all, Have a strange project where I need to run a 2080TI from a 1U server PSU. Looking at using an IStarUSA TC-1U70PD8 700W http://www.istarusa.com/en/xeal/products.php?model=TC-1U70PD8 It has 4x 12V rails each rated at 16A max. Its a super compact build so I am going to have to chop the lines and re-crimp new Molex Minifit-Jr plugs anyway. How bad of an idea is it to bridge some of these buses together to supply the GPU? I'm open to using another PSU, but again it needs to be 1U and have enough "Skookum" to run a 2080TI along with whatever the fanciest of the i9s would pull. Thanks

    Is Bulk Thermal Compound Worth It?

    Hey Linus, If you're interested in giving it another whirl... Innovation Cooling, LLC IE: IC Diamond publishes thermal conductivity of 4.5 W/m-K. This stuff: http://www.digikey.ca/product-detail/en/t-global-technology/S606C-30/1168-1382-ND/3042211 is 5.0 W/m-K. And this stuff: http://www.digikey.ca/product-detail/en/t-global-technology/TG-NSP-60-1LB/1168-2116-ND/5280212 is 6.0 W/m-K. We've used both at our lab in Victoria with good results. Also next day shipping with Digikey
