Adjustable focus HD FPV goggles for Connex Prosight or Raspberry Pi HD FPV Broadcast project

thingiverse

These goggles come in two versions, one utilizing the Raspberry PI HD broadcast project and a cheap dedicated 5 inch Raspberry Pi screen, while the other features a direct HDMI input suitable for an HD link such as the Connex Prosight. I designed the focal length to be adjustable because none of the off-the-shelf goggles I've tried have allowed me to get a decent focus with my prescription. I'm sure this must be the case for many others like me! The only modification I made since doing the video was an optional lens rack to accommodate two Fresnel lenses if you can't achieve clear focus with one. You might be able to do without the Carson lens if you use two fresnels. Instructions are available on these two videos: https://youtu.be/jgBXyjoMyts and https://youtu.be/tNXsQrTrK-M. If the lens mask doesn't quite fit your face, just add more foam!
