Hi everyone, I've been entertaining the idea of making a wall to battery adapter for cordless tools for a while now. The idea is that an adapter can plug into the tool and then connect to the wall outlet to replace a dead battery (until the battery is recharged). I finally got around to it and have built a few of these for Ryobi and Dewalt tool systems. Right now, all the electronics are in a hollowed out battery case, so the adapter can fit normally into a drill/jigsaw/circular saw etc (no external power brick). They work really well, they seem to have the same power as normal battery operation (maybe a little more?). This got me thinking, that I could start selling these (~$40-$50) if there is interest out there, so any feedback would be appreciated. Feel free to ask questions. Thanks, Aaron
