homemade ring light
Image by Oli Pritchard
Inspired by the project at metku.net/index.html?path=mods/ring-light/index_eng. Both photos combined above were of course taken with identical camera settings. This is version minus one, the proof of concept – hence the taped up battery pack (3 old 17670 lithium ions, reclaimed from a laptop battery, in series) and everything held together with epoxy resin. The centre is an empty 55mm filter ring and backing is a conveniently sized lid from a plastic tub. The two LED rings are from dealextreme.com; I used 120mm and 90mm rings, smaller sizes are also available. I wired them in parallel.
