Start of the 3watt RGB

hmmmm is it true that his base-plate is too thin? Because if you say that his plate is too thin because his optics can get screwed up because of heat, I think you're wrong.
The effect I think you mean is the thermal expansion, but if you look at the formula of thermal expansion I'd say you're wrong:

As you can see, thickness (or surface) is not a factor. So taking a thicker plate won't do anything right?

You are right Frixxion, thermal expansion has nothing to do with thickness, but Jim (Smogthemog) is pointing out is that bolting together different materials with different thermal expansion properties is likely to cause a problem.

in fact that is exactly how old-days 'bimetal' thermostats were made: two metals were joined together side by side and form a rod. Changes in temperature cause it to bend as one side would expand more than the other, allowing the sensing of temperature change.

Very pretty

Mmmm... pretty colors... me like!

That thing must be really easy to align with all those adjustable mounts.

But, red+green+blue=green? Is that green really too powerful for the other lasers or is the camera just failing to capture the proper color?

align in 5 mins tops

my client wanted a fully adjustable beam table.

1000mw of green
1600mw of red
500mw of blue

how heavy are laserwave laser heads!!!

the case plus all psu i could lift, add the laser heads and its a two man job to lift the unit

What controller are you going to use?

QM2000 or FB3 built in maybe?

A bit of creative work with your pallete's and you could make good use of all that extra green and retain good colour balance at the same time...

well he said he has a qm2000.

im only making the projector the rest is up to him.

he seems to be into programming not building

Hi tocket,
maybe the rate is not 100% correct(sorry, Andy).
but if you carefully look the second pictures, you will see after combine the RGB and before to the scanner, the light is almost white, .
Hi Andy,
our new type higher power lasers will coming on soon, they are much light than this unit, just a few pictures enjoy it-our new baby, .
Best regards!

can i add a few suggestions for your new range?

the cable that links the driver and the laser head is not flexable at all. its very difficult to work with.

also the holes for mounting the lasers. on the two big lasers there isnt a problem but on the three smaller units there isnt enough room to bolt onto. see below photos.

the red is the bigger laser head where there is enough room to bolt onto to, but the green shows the smaller head where there is only 1mm to bolt onto and the bolt keeps coming off.
