Bye bye Spencer, hello... China?

That's one of the limitations of using SD and why people tend towards a separate DAC and software. Apart from all of the additional control you get, on a PC the limitation is usually the hard drive size and memory when it comes to displaying shows or cues. The problem with a built in SD, apart from the show creation and control issues, is that you only have a certain amount of space available on the SD and a certain amount of system memory vailable to run it. Exceed either and you'll hit the buffers.

I too would recommend Goldenstar. It can't be emphsised enough that you get what you pay for in this hobby. However, there are one or two manufacturers who make small cheap lasers as well as expensive ones and whilst some limitations still exist, you do get better quality for your money within the limitations of what can be provided for the price. Goldenstar are one of those manufacturers.

Of course, I have found a way around the file limitations... I used that I think it's laser show composer to combine different .ild files into one... So one file can have many different ild designs, which gives you more "animations" in less amounts of files. I've done this with a few SD cards...

I'm sure they're way more powerful a unit than I need...

Why not go for the lowest powered laser then:

Its still Class IV, and gives you more room to account for the SD card board and shipping.

BTW shipping is expensive everywhere these days for large heavy parcels and insurance especially by air.

470nm blue? that seems.... wrong

Hi ,friend .It is correct for blue 470nm/473nm ,that is light blue color ,it is more expensive than 445nm /447nm .

Seconded m0f's recommendation for Goldenstar. I've seen the build and beam quality and of one of their lasers and it looked really good and no comparison to the one in the link you shared.

It is going to cost more but it'll be well worth it.

Thirded (if there is such a word) for Goldenstar. Excellent service, reliable and competitive

By my opinion, general problems of chinese embedded SDcard controllers is not possibility to change content in really live: projectors in most situations are without possibility to manual access (for SDcard exchange) to they (they are installed on trusses... or on long distance from operator).
Our Multibus OEM controller fixed these problems: user can write SDcard by Ethernet.
In last version of controller we:
- supported SDHC format (up to 32GB);
- realized geometry corrections (size/position/shear/keystone/linearity)
- modified trigger (music/generator/off);
- setted SizeX/SizeY/PosX/PosY potentiometers.

Wow, they estimated $167 to ship it? <snip> Who do they ship with a private plane?!??

That's actually a reasonable quote given the size and weight of the package. Remember, they only ship via either FedEx or DHL, and it always goes via international *express* delivery.

Yes, that's expensive, but it means you get your projector in less than a week, and you have very few problems with the package getting lost. Also, as a general rule, packages seem to have fewer issues clearing customs when you ship them express. (Express shipments have very clear paper trails.)

Sending it via snail mail can take a month or more, and there's a good chance it will get lost (or stolen) on the way. Then there's breakage to worry about, not to mention customs delays.

No one decides to use the most expensive shipping option lightly. The reason they use international express service is because it works, and regular mail doesn't. (or at least, not reliably enough)

This is very common. Most Chinese suppliers, including Lightspace, Lightwave, Laserwave, and CNI, to name just a few, do exactly the same as Goldenstar.

i'm surprised. none of the price lists i've gotten from you list 473 modules so i assumed you only deal with 445.

Hi friend ,only S-W300 and S-W400 use that 470/473nm laser modulation from it .
