Why is UV better than violet for that purpose?

;) I know you were joking, but I don't think lifetime was.

^A more general rule for optics (e.g. also applicable to telescopes, photography, beam expansion, et al.) is the collimated side of the beam is on the curved surface of the lens, and converging or diverging side of the beam is on the flat surface of the lens. I don't remember why. It does work...

The mirrors just fold a longer design into a shorter, fatter design. A PVC tube coated black inside is functionally the same while being simpler and cheaper.

You haven't given any information about your project. You've only re-stated your pulsed requirement. Please tell us about your project.

20 seconds of googling shows: At 5 million subscribers, estimated revenue for his channel is $180k/year. The video pays for itself in a few days. No illicit substances required.

We can help you a lot better if you actually tell about your project as opposed to demanding (perhaps unwarranted) specifications.

A small optical spanner might have enough torque to break the glue that holds the threaded lens-mount in there. It may be better to leave it alone.

It would appear I somehow I guessed the problem correctly. Your positive lead is soldered to the OUT pin. It should be soldered the the ADJ pin. I would think this bypasses the regulator entirely, minus some intrinsic voltage drop. I don't see how this (exact) setup could power any red, as it...

I don't suppose you connected the diode to the output pin, Mr. Pupper? 11V generated by what? A picture of your setup may help a great deal.

Your question is far too ambiguous, Mr. quptil. It's like asking "what do pills do?" Try again.

The main mistake you've made, Mr. Theimer, is assuming one laser driver will drive all laser diodes without modification in any way.

This is a ~12W heat load, my dude. That's nowhere near any practical limit. For comparison, A pentium 2 has 3 times that power dissipation and still used a heat sink with no fan or heat pipes.

An acquaintance of ours has a great interest in your inheritance, as he, too, has quite an extensive collection. Would you kindly send him a few pictures, or better yet, call him? His website: https://sites.google.com/site/vintagelaserarchive/

Most residential lines are only 7.2kV. A long PVC rod with a hook knife taped to the end is a better idea.

You still haven't been clear on how the stock laser is sub optimal. However, you should be able to easily change the spot size of the original laser.

^From my limited knowledge on resin printing, the cure is energy dependent, not power-dependent. For instance 25mW for 10 seconds is the same energy as 250mW for 1 second, and would in theory produce the same cure, all else equal. What's wrong with the original laser though? If you're a...

Hey, neat idea. The photo-reactive items I've seen are either very slow to change, or are heat-based (like "mood rings"). That certainly isn't my area though. The more common method is to use a violet laser with glow-in-the-dark panel. This works with just a few mW, but the effect is obviously...

Drivers aren't typically tested to withstand brownout operation. If the frequency is a under 5Hz or so it probably won't matter, but it can get hairy above this. For instance, if power is reapplied while the IC is still undergoing its shutdown process from your last falling edge, states are...
