Introduction: DIY Portable Ring Light
Step 1: Step 1
I started with the plastic top from some blank CDs
Step 2:
Divide the surface into quadrants. I used a lens hood that came with my lens to trace out the hole for the lens. Put about 10 LEDs per quadrant
Step 3: Step 3
Drill out the holes and cut out the middle
Step 4: Step 4
Paint it. Make sure you use a spray paint that works with a soft plastic
Step 5: Step 5
Drying
Step 6: Step 6
LEDs in all the holes
Step 7: Step 7
All the LEDs need to be soldered in parallel and not sequence. Working with a 9 volt battery i split the LEDs into groups of 3. Take the positive and negatives from all the groups and solder them togeather.

Added a push button to turn it on/off
Step 10: Step 10
Battery clip
Step 11: Step 11
The hood from my lens is just epoxy'd into the center. Also added an inch of a chopstick with epoxy to the right side for stability when pressing the button

The final product was a little too bright so i added a potentiometer to adjust brightness
