The modern era of virtual reality really kicked off in earnest just over a decade ago, when the Oculus Rift promised 3D worlds beyond your wildest dreams. Still, if you’re keen to tinker, you might like to make your own headset like [CNCDan] has done. The headset has adjustable interpupiliary distance so you can dial the view in to properly suit your eyes. [CNCDan] apparently put the build together for under $150, which is not bad compared to the price of a commercial off-the-shelf unit. [CNCDan] reports good results with the DIY headset, using it primarily with his racing simulator setup.
