Here is a build manual to convert the Cinemizer Plus video glasses into ski goggles using the fpvmanuals Delrin lens and felt kit.

1. Start with a pair of Carl Zeiss Cinemizer video goggles and…

2. … a Bolle Y6 OTG ski mask.

3. Get yourself the fpvmanuals Delrin lens kit, which includes the Delrin lens, sticker and felt comedy moustache.

4. Pop out the original lens and insert the fpvmanuals Delrin lens in its place.

5. Use a T8 Torx screwdriver for the right side-arm (‘temple’)

6. And a small Philips screwdriver for the bottom.

7. Gently lever off the right side-arm cover (it’s now just clipped in).

8. Carefully lever the black connector-latch out (e.g. with a scalpel) to release the small flexi-cable from the PCB.

9. With a thin ‘pokey’ tool, push the side-arm hinge-pin out (this will require you to gentle lever away the Cinemizer goggles’ front cover a bit) and remove the right side-arm from the Cinemizer goggles.

10. Carefully cut through the right plastic side-arm to release the embedded cable. I found this part the trickiest. I used wire cutters, but a Dremel and steady hand would probably be easier. Take your time! Alternatively, please read matthew.wright5 comment at the bottom for a potentially less risky method.

11. Repeat steps 5, 6 and 7 for the left side-arm.

12. If you have no requirement for audio (I didn’t), then carefully unclip the Cinemizer goggles front cover (there are no further screws which need undoing) and unplug the left audio connector from the PCB.

13. This is what you’re left with.

14. Re-attach the small flexi-cable to the PCB on the right side-arm (reverse of stage 8 )

15. Get some Sugru of matching colour. I went with black and I think used 3 mini-sachets in total for my build.

16, Gently push the PCB back into the goggles and after checking they still work, neatly encase the cable exit with Sugru, pushing some of the Sugru into the cable exit hole.

17. Adjust the Cinemizer goggles in the Delrin lens so they’re square and level and you’re happy with their position, both cosmetically and functionally. I found the small nose-bridge on the Cinemizer goggles butted up nicely against the inside of the Delrin lens. Put a cable-tie around the ski mask and slowly tighten (one click at a time) until the the Delrin lens perfectly follows the contours of the Cinemizer goggles. You should now be able to wear the ski mask without supporting the Cinemizer goggles. Again, confirm they still work and you’re happy with the positioning.

18. Use the Sugru around the inside of the ski mask to adhere the Delrin lens to the perimeter of the Cinemizer goggles. I think I used 2 sachets for this. Leave the Sugru for 30 hours to harden and then snip the cable-tie.

19. What you end up with are the coolest looking and best performing FPV centric video goggles you can get!
