Expensive blue was yesterday :)

[Diachi]

I'm wondering if the laser assy could not be bought as a replacement part. That should be cheaper than ripping apart the whole projector.

I was wondering about this too, judging by the way things are worded on the casio site as well as the way the system is constructed it would make sense that the "sled" could be ordered alone as a replacement part.

I have been speaking to a senior technician from Casio today.
Replacement "lamps" are available, however there is no guide price at all; anywhere. They are also NOT a user replaceable part. If you need the hybrid "lamp" unit swapped out. You send your complete projector in to them, and they will swap it. That is the only way.
i.e. the parts themselves are NOT for sale...
Running >>12 hours per day, they are expected to last for at least 10 years.
There hasn't been as single request for a replacement lamp in the entire company so far. Things would look VERY odd if people were suddenly after lamp arrays left right and centre...
Rough ball park price was estimated around the price of a new projector anyway...

good work dan.

i think just order one/some and test power levels whilst still connected to the casio projector.

thens start taking to bits.

like i said dan feel free to send one my way if you want.

Can anyone suggest an option for decent, reliable, adjustable, analog modulation drivers for these diodes please?

[Heavyen]

1. buy casio beamer
2. swap 445nm diodes with cheap busted reds
3. send it to repair cuz it doesnt works
4...
5. profit!
6. get in trouble when they figure it out??
/ end of joke.

ehh, ill just wait for reviews and any further price drop in future
I started thinking about making blue only projector instead of green. It seems cheaper and smaller.

Bring on the GAN green diodes!

AFAIK there is currently no way (yet) to get green out of a diode laser directly.

Cheap GaN direct blue is already a giant leap forward. All projectors using green lasers use 523nm DPSS.

At least we can say the demand for 445 will go up, meaning production will ramp up even further and blue will become the cheapest laser on the planet.

Ten years ago blue laser diodes were the holy grail. Who would have thought?

I'm sure one of Dr Lava's Flexmod drivers would work quite well. And I believe Daedal also has an analog-modulated driver that will work, though it may not be able to supply enough current for full-power operation. (It maxes out at 400 ma, whereas the Flexmod can deliver 6 amps.)

Thanks Adam, I will go with Lava's then.

EDIT - now purchased with Lasorbs as well

My understanding is that a GaN green diode was first demonstrated last year...

I also read recently that a US company KAAI is commercialising green GaN diodes and demonstrated these at CES earlier this year.

Judging by the following picture, it looks as though these are run in serial. I would be interested to know whether or not any additional electronics are involved between the diodes.

Yes, they are run in serial. There's nothing strange about it really - I do it with my red laser diodes without any extra components. I doubt Casio use any in the projector either.
