  • Thanks for the tip. It turns out if you don’t want to use that tiny pad near the button, you can also use the metal laser housing as the positive terminal.

  • I just got my laser from the new batch, but its circuit layout is different from that pictured above. Mine doesn’t have the two solder points, and the spring takes up the entire back of the board. How do I hook it up to power?

No public wish lists :(
