  • After #9 unleashes the tailisman..... it was time to find a new job....At Sparkfun! (#9: How do I put 'I Saved the world' on my resume?)

  • I purchased a large set of the above product suggested from Digikey, but they still do not fit correctly. The outside dimensions almost match from the specifications sheet, but the inside does not allow the pins to fit properly. I have had better luck ordering from Jameco with this particular family of connector housings Jameco Discrete Wire Housing (2 position). I hope this helps.

  • I am there with you Hoobens, I just got mine in today and noticed it was not the same as the description above. Using a meter and some trial and error I found (Sparkfun, please correct me if I am wrong) that the spring and the switch is the ground. If you look at the spot BETWEEN the switch and spring, you will see a silver pad, that is the Positive terminal. For permanent ON you will need to solder your ground to the two terminals to either side of the switch closest to the laser diode barrel. You will also have to figure out a way to solder to the silver pad between the switch and spring as well (I am still working on that).

No public wish lists :(
