Question Back after a few years... 445nm Group Buy?

I've been off of here for a few years - been playing with microcontrollers!

I don't see any GBs listed on the GB board - does anyone know if any are being planned? I'm looking for JUST the diodes, not assembled units or kits... 130s, 140s, 150s... anything I can get around a watt from.

Thanks for the info, and hello to all my old friends!

Dave X

Hello there!
You can always get single diodes from DTR or Daguin, and some other people sell them
too from time to time. Look in the buy/sell/trade forum.
People have generally moved on from groupuys towards stocking up on projectors....

Thanks, Anselm!

Quick question - has anyone combined a pair of these with a combiner cube?

Off to the buy/sell/trade forum!

Yes, but a better option seems to be knife-edging with a pair of anamorphic prisms.

There are people over at PL that are combining up to six of these using knife-edge mirroring.

Just two through a cube is soooooo last week

Peace,

Thanks guys... a lot changes in a few years! I need to find out about knife-edge mirroring since I am a "MORE POWER!" kind of hobbyist... :-)

I still have a few A140 diodes in stock that I never got around to listing on ebay. PM me if interested, I've been selling them for pretty close to my cost plus shipping. I think I have 2 or 3 still available.
