I made this Dorcy DIY 650 red a few months ago. I was just wondering if its the kind of thing that I could sell. It would be in a current regulated 200mW version, and maybe not this exact flashlight. As you can see from the video the circuitry and diode are just hot glued in place, so its not the prettiest setup like those MXDL ones. I'm just curious. I've been thinking about trying to make and sell some.
