Valve's Alan Yates (@vk2zay) spoke with us about the science and technology of virtual reality.

Elecia looked at the iFixIt Teardown of the HTC Vive system as she was unwilling to take apart Christopher's system.

Alan shared some of his other favorite reverse engineering efforts: Doc OK's Lighthouse videos, documentation on github by nairol, and a blog by Trammell Hudson.

Alan's sensor circuit diagrams were on twitter: SparkleTree sensor circuit (think simplified) and the closer-to-production Lighthouse sensor.

Make Magazine talked about Valve's R&D Lab. This is important in case you want to work at Valve (they are currently hiring for EE but if that doesn't describe you and you want to work there, apply anyway).

Alan also has a website (vk2zay.net) though it doesn't see much updating right now.
