edyb] uses his relatively inexpensive Cannon camera quite a bit. However, in dark areas or extreme closeups, the camera’s image quality leaves something to be desired. [edyb] hopped on the ‘net and found out that a ring light may cure his photo faux pas. Ring lights are nothing new but nothing existed for his lower-end point and shoot camera. With a USB-powered lamp and a spare AA battery pack kicking around, [edyb] decided to make his own.
First, the USB lamp was disassembled, luckily the LEDs were already laid out in a ring shape. The clear protective housing and gooseneck were discarded and the remaining PCB ring was glued directly to the camera. A female USB jack was then glued to the top of the camera and soldered to the two leads connected to the lamp’s PCB. The AA battery holder received a small switch and a male USB plug, also courtesy of a few dabs of glue. The now-assembled battery pack plugs directly into the camera via the USB connector and is its only method of attachment.
DIY Camera Light RingThe utilitarian modification may look crude but the results are anything but. Check out this close-up macro shot of a Canadian penny. Not too bad.
[edyb] has done some similar mods to other cameras, attaching components with magnets and even using an old Blackberry battery to power the LEDs showing that there is no one way to solve a problem. Check out the video after the break…
