I’ve always loved the look of photos taken with a ringlight. About 6 years ago, before my son was born, I built a ringlight using some circular fluorescent lights and a chip and dip bowl from Big Lots. It produced the look I wanted, but the ballast required to power the lights made it a bit heavy and unwieldy.
In November of 2009, a fellow by the name of Jani ‘Japala’ Pönkkö made a cool DIY ringlight using automotive LED rings. Since those LED rings could be battery powered, I thought that would be a good fit for the Lego camera.
