l decided to upgrade my HeadPlay HD goggles with some new features. Specifically I wanted to add diversity receivers and a DVR. In case other HeadPlay owners wanted to duplicate my DiY project I purposely selected components that are readily available. But be warned: The task requires electronic skills and a 3D printer, so it's not a project for everyone. Total cost of parts is about $80 USD. Here's some photos of the finished project. A 3D printed enclosure contains the 5.8GHz diversity vRx and low cost SD card type DVR. A toggle switch (bottom left side of photo) is used to select live video or DVR playback video. The original 5.8GHz vRx board is removed (but the LCD driver board remains). A 3D printed filler panel replaces the vRx board and is used to cover-up the vacant vRx's holes. The 3D printed parts help with the aesthetics. It's a bit boxy looking, but the simple 3D printed shapes ensure successful printing on nearly any printer. I used ABS filament but PLA will work too. And the best part is that you can remove the mods and restore the goggles back to their original configuration. The only evidence of it would be five small holes from the mounting screws. Nice!
My HeadPlay HD goggle hacking continues. The recent Diversity Receiver / DVR upgrade was a success so now it's time to upgrade its plastic Fresnel lens. Replacing it with glass optics makes the image look substantially better. There's a commercially made glass lens for the HeadPlay HD goggles that can be purchased for about $40 USD. But I'm a DiY guy. So I did it for under $2 with the help of my 3D printer. Here's what the DiY glass lens upgrade looks like: The retrofit does not alter the HeadPlay goggles in any way. You can remove it and go back to the Fresnel lens at any time. Not sure why you would want to do that, but being able to restore the factory configuration is a nice feature of this upgrade.
