Harvesting the ShowWX? Contains: 635 + 445 (single mode?) + 532 (directly doubled)

Has anyone harvested (or doesn't anyone know of a thread where someone else harvested) the ShowWX pico projector? They're at $199 now, which isn't bad for a device that contains three individually interesting diodes:

RED:
It's got a 635 to 645nm RED diode, running (in the projector) at 90mW. It could presumably hit a bit higher than that with a decent heatsink. Interesting (decently valuable diode)

BLUE:
It has a 440 to 460nm BLUE diode, running at 50mW. Again, it could probably hit a bit higher. Who cares with 445s so abundant and cheap at higher powers? Well I think there's a decent chance that this is a single mode diode, which would be a nice refreshing (and very unique) beam to have.
(EDIT: I missed the best evidence that was right in front of me. The divergence specs! I'm pretty sure those specs ARE a single mode. They're certainly NOT the specs of our well-loved 445s here)
(EDIT 2: That range of 440 to 460 is skewed higher than the range of our 445s, which is generally claimed at 440 to 455. So potentially a higher wavelength blue here)

GREEN:
It has a 526 to 537nm GREEN laser running at 60mW. Who cares with DPSS greens so cheap and abundant? Well, it's not DPSS. It's a directly doubled IR diode. Not life changing, but a completely unique laser to own. I've also read (but can't find the citation) that it's a 1060nm diode that is doubled, meaning potentially 530nm? I might be wrong on that theory, and it's not a significant difference from 532 if I'm correct anyway. But regardless, a unique diode.

I think all three lasers are unique in their own right. In fact I think the RED alone is worth half the purchase price of this projector. It's hard to value the BLUE since we don't really have a good analogue. Single mode 445s are still hella-expensive though, and I've rarely seen them around. However, in my mind, this probably equates to $200 worth of value.

Only problem for me is that the $200 price tag is for shipping to the US only, so I'm out. But this sure looks ripe for harvesting ;)

Does anyone know the diode size I'd find inside?

Sorry for having nothing else to say other than:
I'm interested... but I'm broke too.

Seem like we all have the same problem. Plus i might have lost my job, and motherboard burned.
No job,
No computer,

Eh! I have lasers at least!

interesting... I woulder if you could just open this up, remove the optics module and DLP chip and just feed it into a set of scanners :)

thats like $1/mW for a full color white module with good modulation and probably good beam specs... seems like a nice graphics projector :D

Very interesting for sure! I wonder if the optics could be reused for a laser projector...

That's a pretty tight looking projector. I'd love to take one apart some time when I have money again:whistle:
Also looks like a nice little projector for ACTUAL use as well!

They're not :(
They're 3.8mm

I've got a projector on the way. I'll do a tear-down and harvest walkthrough.

Still need to find someone able to make 3.8mm modules.

Well.... they're worthless to me at present too ;)

I hope this is something that someone is actually to do. I sort of jumped on the purchasing a projector stage, before fulling hashing the "making a module to fit the diode" requirement first. Though I'm not going to do the tear-down until I know that I can actually take it 100% of the way and test the resulting diodes. In case making a 3.8mm module doesn't turn out to be possible, I'll want to be able to sell the pico projector. Or keep it if it's cool I suppose.

Having said that, there is a lot of creativity on this board. I'
