Looks like that diode has a built-in photodiode, pins 3 and 4, that you could use as optical feedback for precise output power control. Pins 1 and 2 are for powering the actual laser diode itself. If you just want the laser to emit light and dont want/need the precise output control you can just...

Lower taxes for them and their 1% buddies...

Trump couldn't broker a deal for 1$ off a fake Rolex in a South Asian market let alone broker any kind of deal between Ukraine and Russia. Like were talking about the same Trump here right? I've heard the guy speak, he just rambles nonsense conspiracy bullshit to crowds of gullible people.

Yeah ending with Russia annexing Ukraine because Trump is a Putin shill and he'll cut all support for Ukraine. Not a good ending.

I dont think its been hacked personally. I think they just dont have a lithium charger and want a quick and dirty solution. Only quick and dirty way to charge lithium batteries I know of is if you have a bench power supply that can do both constant current and constant voltage

No. The voltage is too low, you'd probably permanently damage/destroy the lithium batteries.

I appreciate you wanting to share info, but I would bet that almost everybody on this forum was aware of this already XD.

My setup is just a piece of gypsum drywall sitting on a bicycle innertube on my floor, rock solid even for 15 minute long exposures (I'm just doing Denisyuk holograms, very forgiving)

Asking questions is how we learn. Its not unreasonable to learn about TEA/Nitrogen lasers and wonder if other gases would work.

Yeah I only have a cursory knowledge of gas lasers, but I'm pretty sure argon lasers are a lot more complex than simply creating a discharge through argon gas, IIRC the gain is pretty low so it takes a lot of input energy to get even a small output, not to mention you'd probably need to design a...

Yeah its definitely a labor of love. I've spent a long ass time on this and am only now just barely able to produce reliable results. But the payoff is worth it IMO. Now its just a matter of refining my plate production and post processing to get the quality up.

A few DCG process holograms I've made over the past couple of weeks with my Osram PL530 laser.

Nah, for all its flaws, it was still an impressive thing to have a vehicle that could be re-used that many times. And I still believe had NASA gotten to build their original vision of the shuttle it would have been far more successful and cost effective, but the Air Force got involved and the...

BigClive on YouTube has a running series where he tried carbonating various drinks, most of them dont turn out well lol. Tried carbonating milk once, but the carbonic acid that forms made the milk curdle
