Step 3: Layout

The size of this one was based on the size of the camera sunshade, roughly 4 1/2" X 5 1/2". I added about 1/4" all the way around for clearance, and decided to make the aluminum reflector on which the LEDs are mounted 2" wide all around. The overall outside dimensions ended up being 9 5/8" by 10 3/8". With respect to the depth of the case, I figured on allowing about an inch behind the reflector for all of the components and wires, and about an inch in front of the reflector so that there would be a bit of spread to the individual lamp beams before they pass through the front diffuser. So the depth outside dimension ended up being 2 1/4' which includes the back and removable diffuser.

The lamps are arranged in two rows all around the reflector, and the rows are about 1/2" from the inside and outside edges. This leaves about one inch of space in the middle for the four battery holders, with one on each side. Spacing between the lamps ranges from about 1 1/4" and 1 3/4" with those on the outside row being further apart.

So my advice is to sit down with pencil and paper and and make your own plan. Google's software Sketchup is also great for projects like these if you are inclined to work with software.

Hello :) great Instructable, very thourough. I wanted to share my own ring light build which I made for my GoPro.<br> <br> <a href="http://www.instructables.com/you?show=PUBLISHED" rel="nofollow">http://www.instructables.com/you?show=PUBLISHED</a><br> <br> I've been wondering whether I can put 12 volts on the ring to get rid of the battery pack...thoughts?
That looks like a very nice attachment for a GoPro! But since it is so small I'm not sure where you could stash some batteries. Maybe you could make space for a bunch of little button batteries?
Thanks for the response :) <br> <br>I considered button batteries, but the capacity is very limited. I found some 3.7 V 600 mAh rechargeables in the AAA form factor, they should give me about 58 minutes so i'm going to give them a try.
do you drive these leds directly from 3 volts? or do you have 2 in series with 5 parelel groups of 2 in series?
if you made that completely from scratch i am impressed. looks very professional
Don't you have anything better to do than harass your wife/girlfriend with a light!? She checking her myspace account which means 'my space leave me allow or die'<br>lol JK love ur project
Ha, ha, thanks for your insight. I know our extremely helpful office assistant will appreciate your comment! She was quite willing to pretend to work in the dark so I could demo the light!!!
What's next fill her cubicle with packing peanuts?

This is cool. I've been wanting to take on something similar for a while!
thanks for your comment! It is a bit bulky but the light quality is very good.
How about sharing some sample photos?
Lets see if this link will work:<br><br>http://www.youtube.com/watch?v=H_HcZRNsYvM<br><br>
Very nice results! Thank you!
You're welcome. I think the best use so far was inside a car.<br><br>
I use it with a couple of video cameras, but maybe I should shoot a demo and put it up...
This is fabulous and simple. Thank you for a lovely instructable. Now if only I had the patience to figure out those 3D camera instructions...<br>
Thanks for your nice comment. Yes, I think the 3D rig instructable makes it look complicated, when really it is mostly a matter of properly placing four mirrors and a camera on a base plate. The added parts that make it easy to set the convergence are not really needed -- you can adjust the mirrors by hand very easily.
