techhood on ebay sells them too, no shipping cost but long delivery time is the obvious trade-off

It's standard practice for NICHIA to deny any products that are not specificially sourced through them are legit. Chinese sellers also make up product model names because NICHIA will not tell them the actual information, they don't support reselling. Mostly I think this is because these diodes...

So they came back 5 years later just to update their hate post? 😂 He seems to be under the impression that a forum is supposed to be an encyclopedia or something, but many of us are here because lasers are our hobby and we like sharing it with others, not because we are...

Like Cyparagon said, If you're only gonna run it for a millisecond it won't really heat up and will be fine without a heatsink. Soldering it directly to a pcb is gonna be fine. But you might have to run it for longer than a millisecond to mark wood like you want to. I'm not sure. If you have to...

Pointer? Short answer no. Non-handheld? You can get a chinese rgb package for 25 dollars and mix the red and green till you get orange. It's a cheap way to get a wide range of colours + "white". Note that these are not aligned very well from the factory and might require some DIY

WOW that is some pretty good alignment for such an array.. the Nichia one I mean. Thanks for showing this

I'm sorry for responding so late, I've already told Bob but I ought to explain myself to everyone. I've been very busy the past few months and have had absolutely no time for the laser hobby. As such I missed the window for the order. Right now I'm also short on money so even if I had had the...

Holy moly, looking forward to a video of that beast in action

Darnit, I had high hopes for these FAC diodes to be an easy fix for the crappy multimode divergence.. Thanks for buying, testing and reporting about them on the forum though, much appreciated (y)

Well for one the threads are MUCH smoother on the C6 (at least the ones I got from SL), and the finish is less shiny which is what makes the 501b look and feel cheap imo. C6 is also smaller and lighter, but that does mean the 501b has room for a bigger heatsink.

Huh, it almost looks like your lens is installed backwards. Have you tried it the other way around? GLWS

That's absolutely terrible :oops: The first video because he's obviously injuring himself and the second because she's actually advertising the damn thing! Cool video pyro, that's one scary unit. For my own safety I will never buy such a thing 😅

Behold, the art of trolling:

For TTL cheap ebay/aliexpress drivers work fine, for instance you can even find a complete kit with module and laser for ~22 dollars: https://www.aliexpress.com/item/405laser500mw-withdriver/32562052620.html

That's a pretty cool idea! @Lifetime17 could possibly help you out
