@azonenberg @janamarie
I guess you'll see me at embo++ then?@PeterSommerlad @janamarie wrong conference I'm speaking at https://harris2026.mpi-sp.org/
But if you're in the area and want to say hi, by all means

@janamarie If the extra dot in the corner is a plain simple silicon diode, you could excite it using a red laser pointer.

@Mecrisp ooh, will try that in a bit

@janamarie Good luck! The one for static protection will be reverse biased, so you get at least an hint for the polarity of the array by measuring the voltages when shining on the extra die.

another glamour shot, I should do a focus stack! Also this device is both tiny and way too large at the same time, it’s also quite heavy!
@janamarie @bimmer Wonder what it tastes like?

@catsalad @janamarie my money's on 9V battery but milder

I don't actually know much about this LED, but it's certainly a very strong, possibly ultra low wavelength UV led. The incredibly clear cover-glass and the fact that the dies are water-cooled give off an eerie vibe.
I’m actually scared of figuring out the output power and wavelength by hooking it up to a lab supply. Anyone who knows what specs this could have? What part no it could be?
@janamarie
As a wild guess, could be the LED for a LED-pumped Nd:YAG fiber laser. Never actually cracked one open but the construction, water-cooling, and general vibes are all about right. -

too much of a software guy to be aware of this event. unfortunately i am booked all Saturday and returning on Sunday.

@PeterSommerlad @janamarie then we won't overlap anyway my flight lands DUS around 5pm Saturday so by the time i get to bochum it'll be late

@janamarie this looks like it may just be a very high power white module, but may also be a UV curing module. Either way, this is definitely in the 100W+ class and you do NOT want to look into it either way. Or operate it without water (distilled only) for even a MINUTE.

@janamarie And to be turned on when on the proper heatsink and not in line with your sight - being it in the visible range or not.

@janamarie Looks like the last thing one would see

@janamarie Demon Core (pocket edition). 🫣

@janamarie any idea what the small separate die in the bottom right is?

@jasper not really, could be a TVS diode

Is it cold to the touch?

@janamarie This looks suspiciously like the 405nm 9W LEDs this person posts about? (first attachment)

@janamarie And not to miss the point here: what a gorgeous and terrifying hunk of Technology! Thank you for sharing
