Beauty ring flashes are popular for photography headshots because they provide an interesting catch light in the subject's eyes. Not sure how many of you caught this video, but this was a DIY ring light I seen a while back from Flickr photos. Here's an old version of this https://www.flickr.com/photos/rodolfonovak/196220050/
Now that DSLR's are shooting HD, this project seems to have resurfaced for use with video from Vimeo member TLA Productions. It's a simple design that anyone with a bit of electrical knowledge might be able to tackle, but if your clumsy or clueless, then you can probably just build out the basics and ask an electrician to finish the wiring. Shouldn't be more than a few bucks, and a couple of hours and would be great for Photos or even a Photo booth project too. It's going to provide a much different look than smaller LED ring lights. The bigger your light source, the softer the light and it really shows when used in this video. Looks like i'll have to revisit this project again...

Here's another idea. If you want something closer to Daylight, bulbs that aren't as Fragile, draw less power requirements, and generate almost no heat, check out these LED house bulbs for the DIY Ring Light project. They might be something to look into as an option.
