I made mention, a month or so ago,
r-p-m-c lasers has some HL6750MG diodes for sale. I think they're ~$40 each. Per an email, they have 16 in stock. I thought I'd stop in to see if any of you would be interested in these. OR, any other they list in stock on their sight.
If a few jumped in, it...
Okay, call me weird...
For some reason I’ve been wanting to make a slim pen-pointer, which would use AAAA...yes 4-A, cells. I don’t want to just buy one; that’s no fun.
Are any of you machinist types able to make a thin-wall brass or Al tube with threaded aperture and battery-end caps, and...
I originally posted this as a separate thread, but found this area to be more appropriate. Apologies for that.
I’m not sure if a member on here is selling these or not. Anyway, I found these being sold on eBay, new in box supposedly. I pulled the trigger on one and thought I’d share in case any...

Speaking of reverse polarity... G, have you considered incorporating a fuse on your up-and-coming drivers?
In a “oops” moment, if you burn a ceramic smd fuse from a backward installed battery, you can unsolder it and solder- bridge those pads and you’re back in business. Kind of a last-chance...
I’ll have to try that. I set the lens, diode module w/ G2, driver, switch, and battery all on a flat, long wood base. The lenses I used were the techhood pair shown above. The set came with two convex, and one concave. Perhaps I’ll try without the G2.

I have some of these in red spectrum. I tried to correct an Oclaro 700mW 638nm with them, they did ok with correcting the divergence. Not terrific. Correcting lower divergent diodes like m140, and NDG7475 is pretty good though.
