Intro: LED Photography Light

Hey everyone, in this instructable I will show you how to make an LED light for photography. It can optionally be controlled by a smartphone.

Step 1: Parts and Tools

Here are the parts and tools that you will need to make this project:

Parts:

Ultrabright white 5mm LEDs (x6)

Linkit ONE board with WiFi antenna

Acrylic (3mm)

2n2222a NPN transistor

1k ohm resistor

Tools:

Computer with the latest version of the arduino IDE and linkit ONE drivers

Bandsaw

Desktop printer (for template)

Soldering iron and solder

Hot glue gun and hot glue

Step 2: Cut Out Template

Using a desktop printer, print the attached template. Then, cut it out on a bandsaw. Cut out the "bottom" piece in either translucent white or clear acrylic. I chose white.

Step 3: Glue Enclosure Together

Glue the long rectangular side pieces to the smaller side pieces at a 90 degree angles. Then, add glue the second long rectangular side piece to make one big hollow rectangle. Now, glue the white or clear piece to the bottom of the hollow rectangle. Don't glue the remaining top piece on yet.

Step 4: Glue LEDs

Hot glue the LEDs to the box, one in each corner and one at the middle of each side piece.

Step 5: Wiring

Use the wiring diagram to solder all electronic components together.

Also, you will need to attach the WiFi antenna. Do so by flipping over the Linkit ONE board and plugging the small uFL connector to the connector that says "WiFi/ BT ANT".

Step 6: Code

Download the (1st) attached code, open it, and modify the line that says: "#define WIFI_AP "Your Network"" by changing out "Your Network" to the name of your WiFi network. Do the same for the next line, only you will type in the network password this time. Now, upload the code to the board. Once that is done, open the serial monitor and copy the first IP address shown.

Now, download and open the 2nd attached code and change out the same two lines as last time. Then press upload.

Step 7: Testing...

To test the light,

    I like the idea but 6 of these LED's are just really weak...

    I've just finished making a 200W Variable Spectrum LED Panel as a photography light, And I'll be uploading how to make it in a couple of days!

    Yeah, I just had some LEDs laying around and decided to make a lower powered one. I'll make sure to see your instructable!

    Useful light-box.

    Lower powered light-boxes like these are brilliant for close-up work or for transferring old large-format negatives to digital.

    Sometimes, less power is just what you need.

    Why waste component count and specification though?

    Besides, if ALL you use a photo ligt for is close-up or film transfer (which I do), anything else is a waste.

    It is optionally remote controlled, but if you don't have internet access it is constantly on. When in remote control mode, you can control the brightness. I may add strobe eventually.
