DIY SmartPhone Ring Light





Introduction: DIY SmartPhone Ring Light

About: I like to create useful and fun things. I'm 16 and aspire to be a multimedia creator and an entrepreneur.

Although I usually do all photography/video work on a dslr, I wanted an easy way to light my subject evenly with my smartphone. This ring light is super easy to build and requires very few materials. You'll be able to complete this project in under half an hour. Hope you enjoy!

Step 1: Tools and Materials




-Soldering Iron


-Phone case (got mine from ebay for 2 bucks)

-9v battery

-9v battery connector clip

-Tinned copper wire

-White LED strip


-Switch (can be any switch, I used a slide switch)

Step 2: Cutting the LED Strips

-Cut the LED strips into 4 strips

-There should be markings every 3 leds or so indicating where to cut

Step 3: Cutting and Bending the Tinned Copper Wire

-Cut 8 strips of tinned copper wire, each measuring about 2cm

-Bend each strip to a right angle as shown

Step 4: Soldering the LED Strips

-Solder the tinned copper wire to the LED strips as shown, be sure to solder together the positive to positive and the negative to negative

-Continue soldering the tinned copper wire to the LED strips until you form a square that looks like the picture

Step 5: Cutting, Connecting, and Soldering the Battery Clip

-Cut the 9v Battery connector leads similar to what is shown in the picture

-Solder the positive wire to one lead of the switch

-Solder the remaining positive wire you cut off the battery connector to the other lead of the switch

-Solder the negative wire and positive wire of the battery clip to the corresponding tinned wire of the LED strip square

Step 6: Applying the Components to the Case

-Use double sided mounting tape to apply the switch and battery

-Use the adhesive backing of the LED strip to apply it around the phone camera


You are now finished, get out and shoot!

Step 8: Notes

-In the event your LED strips do not work, make sure your polarity is correct and your solder joints are secure

    Next time try using one strip warm and one strip cool white LED. You will get natural sunlight color. Also try using 5630 LED types. They are brighter and more efficient.

    This is just so simple and cool!

    I absolutely love this project so much!

    where did you get the LED Strip from and how much was it? shouldn't you put a resistor between the batter and LEDs?

    I got he LED strip from ebay, super cheap. Regarding the resistor: No, the suggested voltage for the LEDs is 12v, so using 9v requires no resistor and it keeps the LEDs cool (temperature wise).

    Hi, I like this very much, but can there be a 3.7 v or maybe 5v led strip instead? Just wondering.

    Yes, you would just need to step down to voltage or use a different battery.

    This is a great idea! Do you have any photos you have made with the light attached to your phone?

    Great! I used the same copper wire technique in my ambilight instructable :p
