This is a wearable LED ring I built based on the Instructable here: http://www.instructables.com/id/Ring-Light/?ALLSTEPS
-Hand carved red oak ring
-single ultrabright LED
-removable CR1220 battery
I used 2-part epoxy to attach the parts and glue down all the wires to prevent snagging.
I like the format with the wooden ring since I carved it from scrap wood and it is sanded very smooth to be comfortable and light weight. I would like to make the components more compact, probably trying to use a smaller battery and find an SMT toggle I can mount on the LED heat sink.
