It is possible to make your own video Frenzel Goggles. The cost compares favorably with the commercial versions which generally all cost $1000 or more. Of course, in return you have to spend much more of your time, and the quality may not be as good as the commercial goggles.
The content shown below were contributed by Michael Duchaj, a physical therapist in the Chicago area. He commented:
"I have been working on goggles for my practice. This is the current version. I use an IR camera with attached leds. The focal length is 4.5" so the tube is needed. It's analog so I can hook directly to a monitor or dvr. I use a converter to hook to HDMI or a different one to hook to USB. Parts cost is $65. There is a little fabrication for the PVC tube. "

This PDF contains instructions for this build.
We think that this build is an improvement over the Guevarra and Chiong (2004) goggles which were implemented with visible light. The posting of the construction instructions are immensely useful as they provide a starting point for future builds. We do think there is room for improvement in ALL video-frenzel systems - -see our suggestions here.
