As some of you in the UK already know, this has been a long time in planning, but finally my builds have started...
I am building 3 projectors around 5 watts each and as usual I'll be documenting them with photo's as I go along... Before I get into the details, I have to say a massive thanks to Simon (AKA P1t8ull) for designing and building the most spectacular modules known to man, and Dave (AKA Dave at Lasershow Parts) for the enclosures and all the amazing circuitry he has built for me...
What's in the box?
638nm red @ around 1.4 watts
532nm green @ around 1.4 watts
445nm blue @ around 2.1 watts
Each laser is around 4mm with 1Mrad divergence and the beam is a lovely shade of icy white, with a combined spot that is almost a perfect circle...
Scanning is provided by DT40 Pro's and the magic is provided by breakout boards built by Dave... The breakouts give the following list of functions...
Remote interlock along the ILDA cable
Startup delay
DMX controlled colour intensity for each individual module in each individual projector
Shutter control, for my Pangolin actuators
DMX controlled X/Y axis flips
DMX controlled Red/Blue colour flips
DMX blanking, which allows for projector head chases
Two servo's holding drop down scan through diffraction gratings
The projector cases will have adjustable hardware masks for overhead shows and Pangolin safety lenses for audience scanned shows... I am also building a rack to control these beauties along with my other systems (2 watt GB's), the rack will contain 3 x QM2000.Net and a DMX Merger for all the clever tricks...
As you can imagine, there is a lot of work to be done, but thanks once again to Sir P1t8ull, we saw a beam last night...

Red measurement...
Green measurement...
Pretty colours...
Roughly aligned for first white beam...
How bright??? This is hitting a black heatsink!!!
You can actually see the beam in daylight...
That lovely spot at around 28 Mtrs...
A red beam which could be seen for quite some distance. Shot's like this are a benefit of permanent CAA clearance due to a scientific laser firing at the moon just down the road from me...
More to come as I get further into the project...
