ILDA Compliant Projector Safety Board...

[f22warzone]

Oh... man you're a smart guy : ) Thanks for all your help so far

Just wondering but do we have any idea when Adam would be coming out with this because I would be willing to pre order it if that helped on bring the bulk cost down. As this is exactly what I am looking for.

No optocouplers to kill the RGB signals?

and no scanfail?

If you add this it would also be interesting for europe

I think this idea is great! I would definitely buy one. As nice as audience scanning can be, I don't think I will ever attempt it. It just seems too risky IMO. I know that it can be done safely if everything is calculated and planned properly, but for me overhead is good enough. Here in St. Louis most of the audience would be freaked out by it if I were to do audience scanning and the event promoters would most likely not allow it. St. Louis audiences have never been exposed to audience scanning since every laser show provider that has done shows here does overhead shows only. I've heard comments in the past at events from audience members who were concerned about someone in the audience having a laser pointer (as they should be) so I can only imagine how some might react if they saw laser beams directed into the audience. It's kind of amazing to me how many audience members here recognize the potential danger of lasers.

With the simplified method of Greq and Bill it's very easy to do the calculations, and as you could have read in the documents Greg made you would see audiance scanning is not that "risky" even with the many "unsafe" high MPE shows done every day on the world, almost no accidents are reported.

I think its good to at least try it (not with real audience) so you know what is safe and whats not.

And even with overhead beams (no audiance scnanning) i think it's a must to have a scan fail becouse when a scanner fails its still possible a beam can hit the audiance.

If you diverge the beams and do the calculations, and make sure you've got a scan-fail interlock, sure it's easy... The problem with performing an audience-scanning show in the US is not about the mechanics of making the show safe. The problem is GETTING THE VARIANCE APPROVED. That's the hard part.

To wit: It took Pangolin nearly 2 *years* to get an audience scanning variance approved.

That's why almost no one does it. (Well, that and the legal threat... We do live in the land of lawers, after all.)

Yeah, Steve is pretty much PL's wizard- he can whip both photons AND electrons into submission

is this going to be a bare board or do you have any type of housing in mind? (wrong thread- I realize this is an in-proj board)

EDIT: man, I am thread crossing on these 2 custom board projects!!!
Adam (both Adams ) deserve a tip of the hat for their contributions around here- absolutely

Any updates on this project?

The groupbuy for scanfails is almost finished.

Now I'm looking for schematics for the interlock system, especially for the part where the laser stays off in case the mains was interrupted.

like buffo said:
One more request: in my opinion the projector must never start unless commanded to by the operator. That is, you have a 'run' button that will start/re-start the projector. If any interlock condition fails the projector, the projector will not re-start until the 'run' button is pressed.

I found a schematic on laserfreak.net but this doesnt have this fuction i think

Schematics please

I just looped a latching relay in to the circuit that kills the ac to all of the psu's. I can restart with a reset button on the side of the mushroom switch housing, or one on the projector case.

Are you willing to share the schematic?

Of course, you'll have to bear with me while I draw it though.
