I thought about using my LED-ring as light for macro-photography. Things seemed easy, but I wondered how to mount it to the lens. Then I looked around thingiverse and the thing 2494300 came along. That´s it!
I took the idea with the TPU-tongues and started to design my own ring, that should be as easy as possible:
I use older lenses with distance-rings on my camera. Those are about 60 mm in diameter. But I could mount the LED ring even to some of my modern sony or nicon camera-lenses, which are wider - so up to 74 mm should work.
To print for the ring itself:
To print for the arduino
is based on an example that come with adafruits neo-pixels-library. I changed it to my needs:
The LED-ring is powered on by connecting the power-bank. A light running around the ring indicates that. By pushing the button you now can switch in between modes as shown in the video: https://youtu.be/S5NwynKb-O8
