Custom HMD.

Head-Mounted Display

January 20, 2013

Inspired by Palmer Luckey's Oculus Rift, I created this in anticipation of the first Oculus DK1 release.

This HMD is a modular unit that can be used with a variety of head-mounting apparatuses. The 5.6" TFT LCD and LCD controller are both integrated into the display unit. Power is provided through a 12V DC adapter and video can be fed though HDMI, DVI or VGA. Aspheric lenses were used for consistent magnification across the field of view.

After taking interpupillary distance measurements, a customized enclosure was modeled to scale in 3DS Max.

Without access to a 3D printer, the alternative was unwrapping the model into 2D and cutting the patterns from foam-core board. All pieces were built in this fashion. For example below are a few pieces to be cut, folded and glued, for the front of the casing.

Head tracking was “implemented” by hacking a gyroscope mouse and soldering the power lines to the LCD controller. The gyroscope communicates wirelessly with the original USB receiver. This was the simplest solution that did not require a complex software integration.
