Got it!From that photo? What laser diode--there is no laser diode in the photo? FYI, nothing + nothing is still nothing.
If your time is worth nothing you can attempt tp power it up and/or disassemble the entire thing and figure out what it is, if you have the skills, knowledge, test equiptment required to do so.
You pulled this out of a 41¢ keychain, didn't you?
Hi,Na it's one of those dollar store key chains. They have a dim white LED and a red laser. Two buttons for each function. I got a few new ones saved somewhere. Maybe I'll look for one and post pics. They don't last.
