DIY Portable Ring Light

I started with the plastic top from some blank CDs

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

Drill out the holes and cut out the middle

Paint it. Make sure you use a spray paint that works with a soft plastic

Drying

LEDs in all the holes

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.

Should look something like this

Added a push button to turn it on/off

Battery clip

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

All done
