Will Casio/Sony use resin on there future laser heads?

or they could just replace the drop-in light engine :na:

Yeah, I seriously hope no one is thinking about combining strong acids and solvents in their garage. Or heating acetone at all, for that matter.

But as far as the topic of this thread, you mention the Sony projector. As far as that projector, if it comes out as currently described, it won't be anything like the current Casio projectors. Everything I've read about the Sony says the red and blue are multi-emitter bars, meaning all the blue lasers will be in one package and all the red lasers in one package. Not divisible into parts the can be sold to offset the costs, and way worse to collimate than the current multi-mode blues. So for the very expensive price, a hobbyist will get 1 blue, 1 red, and 1 green laser, not many separate lasers. The price difference there is likely to put-off many consumers/hobbyists who wish to take the projector apart.

This all assumes the product is released in the same form that has previously been described, but who knows what could change.

That was my first thought as well.. Are we trying to ensure we never have access to these kinds of diodes again? 'Cause this thread is a brilliant start. The folks making those kinds of decisions DO pay attention to LPF.. especially now that they know we are harvesting from their products.
Yikes! Well then I hope they don't decide to cover the diodes with bubble wrap secured by duct tape! That would be the end of it all! :whistle:

@PBD: I'd still take 'em.. Beautiful thing about show lasers is that the packages don't have to be tiny. Plenty of room to house a set of corrective optics.

Meatball, you're a genius..

it would be extra terrible if they put the diode in in a way that would allow someone to unscrew something and the diode just popped out. That would be extra hard for us. Also if they used some better lenses, that would stop us from getting the diodes too :)

Absolutely, many of us will still take them. But they won't be of nearly as much use to a very large segment of current laser hobbyists, because the cost and know-how required will be quite high.

The Casios are great for Wicked and non-expert users because single diodes come out of them for very little money. When you get 3 hard-to-use lasers for the price of a $1k projector instead of 24 easy-to-use lasers, it limits the appeal to casual users. I think many expert users will also think of this as a good thing.

why put out ideas to help somebody make our hobby harder?

You never know who you are really talking to. It might be an executive from a company picking our minds. WL does it all the time. Not saying this is one of those examples, but your question is valid. Kind of a stupid question to ask here. That question is best asked after it actually happens. I've seen these kinds of questions from other people in the past. Those NASA guys to name one. The companies save 10s of thousands of dollars letting us do the R&D work.

Relax they will not be severely bricking these things. they are made easily available for the reason of failure analysis. To do it right would require millions of dollars of new equipment and specially purpose- built $,$$$ bar type arrays, even this being the case you'll still have an easily extractable 24W blue laser diode that could be used for other things. the design needs to have a point source at the phosphor disk, converting it to sa kick butt show laser would be trivial for someone with even minimal optics experience. As for the resin bricking technique any choice of these three: Mill Solve, Drill Press or Band Saw.

Gasoline has a flash point of -40C, significantly lower than acetone's -20C. Filled up your car or a hot lawnmower recently?

It seems that 98% of people confuse flash point with autoignition temperature. Flash point is the temperature at which a volatile liquid can produce a flammable air mixture. Autoignition temperature is the temperature at which that flammable air mixture will light up by itself, without the need of any flame or spark.

Even that yummy ole' ethanol has a flash point below room temperature at 12.8C. Autoignition temperatures are gasoline: ~250C, ethanol: 365C, acetone: 465C. Keep your solvent use in an open, well ventilated area without sparks or flame :can: and you'll be fine, just like every time you pump gas.

yeah, I was gonna correct myself but was too lazy. The autoignition temperature of acetone is almost 500 degrees, so hot acetone is safe for PROFESSIONALS to use for melting resins. Also, I watched a video recently about removing the plastic shells from ICs... I'm pretty sure they used fuming nitric acid and then neutralized it with acetone.
