Here’s an intriguing project that comes with the usual cautions about not working with AC house power unless you know what you’re doing, and an extra caution about the risk of burning your house down by trying to roll your own light bulbs. This builder decided to risk all that to reuse the “ballast cases” and Edison bulb screw connectors from dead CFLs (Compact Fluorescent Lamps) to create his own 7-bulb LED lights. Pretty cool, if you don’t electrocute yourself, cut yourself, expose yourself to Mercury, or burn your house down. Oh, and that’s not a standard or safe way of using or powering a breadboard. This guy obviously like to live on the edge. (Check out some of his other projects, like the broken incandescent bulb lamp.)
