Here are just a few links to the do-it-yourself models.
- David X. Tejada has put together a nice and portable unit with the help of a salad bowl, some ducting, two feet of dental floss and a paper clip.
- David Hobby went large scale with his multi-light setup, which is probably not designed to be used around the easily frightened.
- Paul Duncan put together the simplest design, which works well in the studio.
Duncan's ring light is the only one I have tried so far because the other two require parts that I don't have around the house. I plan to try Tejada's next, though I will probably form the base from a bit of steel instead of buying a flex arm.
