Ring-Light For Macro-Photography

thingiverse

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: https://youtu.be/S5NwynKb-O8 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. ### Parts used - Arduino-Nano (with pre-soldered pins in my case) - 32Bit RGB LED Ring WS2812 5V ähnl. Neopixel (11/9,5 mm diameter) - push-button (6x6 mm) - simple powerbank - screws (3x10, 5x) - double sided tape - some wire - an USB-cable to power the arduino To print for the ring itself: - housing (white) - TPU-tongues (here blue) - a smaller ring (here black), that holds the TPU in position - a lid/cover printed from transparent material To print for the arduino - housing with hot-shoe-adapter - the lid ###The sketch 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
