Second Round of Refinements to STEM System Plastic Molds


After reviewing the last iteration of the plastics we determined that some issues were not entirely eliminated. Below are details of actions we are actively taking with our manufacturer to resolve the final errors in our housing design. Please note that these types of refinements are typical during this phase of plastics production.

These resolutions are estimated to be completed by the end of April and we’re expecting to receive the second round of test plastics from our manufacturer shortly thereafter.

We appreciate everyone’s continued patience with us as we iron out these final issues with the STEM System. These fixes will help ensure that the systems we ship have long lifetimes and consistent performance for both mobile and desktop VR.

STEM Plastics Update


First of all, we sincerely hope everyone had an enjoyable Holiday Season and we wish you all a very Happy New Year.

After making the required fixes to the plastic molds, as noted in the previous update, we are now awaiting shipment of the final plastics. All the electronics are ready for production; they merely require their housings. We’ll be providing another update in the next couple of weeks after we receive the plastics shipment and system assembly has begun.

Here is a video of the STEM System in final plastics. Please keep in mind that, as with the images in the previous update, these plastics are a “first shot” on the fixed molds and the texture finish is not representative of the final product.


STEM Plastics - First Look


We're very happy to share with you pictures of test STEM plastics, still warm.

Please keep in mind these images are of “first shot” plastics from our tools and do not represent the final plastic finish.








The test run revealed cosmetic and functionality-impacting errors and inaccuracies in the tools that are currently being corrected.  The following pictures show the errors.










Manufacturing Progress and Images


Here are progress reports and images from our plastics manufacturer:

































We still hope to start shipping in December and have all KS systems delivered by February.

To all of our backers in the USA, we’d like to wish you a Happy Thanksgiving!


Manufacturing and Shipping Update


We have begun manufacturing, but we will be delaying the STEM System again and shipping will start this December.

Also, we added two important capabilities to the STEM System that will be guaranteed to make VR/AR developers’ lives much easier:

1)   Multi-frequency Bases controlled via SW – each STEM Base will now be able to run on any one of 4 different magnetic frequency sets, assuring that those of you receiving multiple Bases will be able to run them simultaneously without interference. Note: RF communication is currently limited to 12 channels.

2)   Tracker Auto Syncing – trackers no longer need to be docked in the STEM Base for their initial magnetic tracking syncing. Simply get everything powered up, keep the trackers steady for a second in any position/location within 8’ of the base and you are synced and ready for action.

We’d like to share with you the injection molding kick-off agreement for the plastics tooling below. The first run is scheduled to be received by our CA contract manufacturer in 55 days.

Once again, thank you for your continued support.
