I apologize for being away for so long. The pictures above and below were taken over a year ago and I meant to format and publish them back then but some other business and life events got in the way. The…
On the left are a series of power measurements I made on the Celluon PicoPro projector with an optical engine designed by Sony using a Microvision scanning mirror. The power was calculated based on the voltage and current from current coming from…

With Microsoft’s big announcement of HoloLens and spending a reported $150 million just for HMD IP from the small Osterhout Design Group, reports of Facebook spending about $2 billion for Oculus Rift, and the mega publicity surrounding Google Glass and the…
