PsyVision adds another dimension to ordinary displays by creating a futuristic hologram! A motor turns a crankshaft that reciprocates a LCD screen producing a POV effect in the Z axis, thus creating a holographic “field”. The device we built for the competition can be seen in operation here:
We used slotted angle and 8mm threaded rods as the support. Â The motor is a Razor scooter motor, the display is a Haier portable TV. Â We’ve used a deep cycle battery with wall charger to provide a portable power supply which can be charged by a bike generator or solar cell. Â The graphics are contrlled by an UzeBox video game boardÂ which contains an ATMega644 Arduino controller chip. The UzeBox provides the video and plays back sequences of the horizontal frames to create slices of the 3d object. Â Different sequences can be controlled with the attached NES controller.
We had to extend the 26 pin cable that goes to the screen to lighten up the top part. Â We did this by routing the video through an IDE cable, here is a video of the soldering:
This device has limitless applications in education. Â For one, it can show an advanced globe where students can sit around and view from all angles. Â Later versions will have a touch screen forÂ interaction.
