Step 2Assembling the light rings
I used the cover of a 10 pcs CD/DVD case as the base. I am using the biggest 120 mm ring which fits comfortably in the case. Cut a circle in the middle to fit the adapter ring. It depends on the type of your adapter ring, but the CD case should site on the rim of the adapter ring giving enough space to glue the two together. I used regular superglue (CA) to glue these two parts together. Cut back the side of the CD case. I was originally planning to cover the front face of the ring light, but so far it is open. Keep the side the same height as the whole assembly (adapter ring depth and LED ring depth) in case you wish to cover it with a semi transparent material to help diffusing the light. With all LEDs on, the light diffused enough. I can’t see the individual LEDs in the pictures unless shooting something highly reflective.
Using a soldering iron I removed the leads from the LED rings and soldered my own cable on. I had some 3 wire cable around, from which I used 2 wires. I left the cable around 1 m long which would be the distance between the box in my pocket and the camera in my hands. I soldered the other end of the wire to the 3.5 mm jacks. I used the bottom ring for the ground (marked as “-“ on the back of the LED ring) and the tip for the positive voltage (marked as “+“ on the back of the LED ring).
Before soldering the jacks on, I drilled small holes on the case one for each ring push the cable through the hole. I tested that the connections are working and the all 3 rings are working. This is important before gluing them on the base. After that you will not be able to access the back of the LED rings. I used two part epoxy to fix the rings to the CD case. I used tape to fix the cables to the back of the case 5 centimetres from the holes. I glued (with CA) the cables to the back of the case to fix them in place. Then I put some more epoxy over the wholes and the first few centimetres of the cable to lock them in place further.
That’s all there is to it. As I said you can think about mounting a screen on the front if you wish to diffuse the light. I might do it in the future, but I am happy the way it is at the moment.
