What am I missing?

EDIT: Solved. See image below. Feel like an idiot now.

Well.. thought I was on the right track with this 488nm pen. Apparently not. I have it set up where if I apply power to the driver, I get a nice beautiful beam.

The switch, however.. I can’t figure out.

I’ve attached a lead from the diode case pin to the drivers negative. And then a lead from the drivers positive to a point on the switch where I got a good reading with a MM. But when I throw it all together in the Laser66 pen host, I get nothing.

DTRs site says that the third pin on this diode isn’t used. Does that mean I can’t use it as a case pin? I’m all confused.

So this must mean the case pin is doing its job.

I can’t believe I didn’t notice this before now. The dummy battery wasn’t making contact with the case because of the wrapping. Took a razor to it, now just a matter of assembly

Hey happy to see the project moving along, thanks for choosing me, stunning build with the laser66 host!

Been there, frustrated the living heck of out me. Glad you got it sorted!

Thanks! The driver works wonderfully. Can’t wait to put the other two to use!
