SMD LED Ring Light board assembled

With the advent of high-output, relatively-inexpensive white LEDs, it is possible for a hobbyist to make a miniature solid-state ring light with surface-mount technology. The LED ring light featured in this article costs about $10 in parts (PCB, LEDs, resistors, wire, and solder). If you’ve never tried soldering surface-mount parts, this is an excellent project to start with.
