New 3 Watt Customer Build

[Stuka]

As a hobbiest with hopes of SOME day trying to recoup at least part of my investment, I'll have to say that this thread has turned out to be quite informative, even if the round-about journey it took wasn't the original intent!!

From my observations:

1. Marc's responses to the "public inquisition" have pretty well covered any questions I might have about building with a variance in mind! Thanks, dude!
2. I'm in the wrong business - I should be a consultant. I don't care if it's certifying laser equipment, or providing "expertise" for government aviation & weapons projects (which I know a little something about) - CONSULTING is where the EASY money is!
3. I don't care what anybody else thinks / cares - Marc builds some NICE rigs!!

So there.....

If the laser *by itself* can be removed from the CERTIFIED housing and *EASILY* (without modification) lase, than that laser needs to, ON ITS OWN, conform to all safety regulations and at that point, the laser source BY ITSELF must contain at least one system interlock.

you know I really hate to split hairs but your using laser wave lasers, all you have to do is flip one switch and the laser can lase on its own without any external input signals outside the projector... i would consider that falling under "easily"

regardless you know I would happily refer anyone looking for a laser/projector to you

that is 100% correct! And under those circumstances, the laser, by itself, if *outside* of the end certified product, would have to adhere to all the safety requirements. Under these circumstances, This laser *by itself* is not wired as such where it can only lase if given a signal. Once the laser is installed inside of the projector, which has its own safety features as a *complete system* the individual component does not need to adhere to the safety reg. due to the fact that the *complete* end product is certified compliant. this is pretty much the definition for an "OEM" Laser module. the laser is specifically designed and intended to be used in a "User certified" and end user compliant laser system. It *is not* certified and legal to be used in any public setting whether for entertainment or anything else, stand alone on its own.

If the module was installed into a projector as a CW beam source, at this time, there also would have to be all of the other safety features we are discussing becasue the laser is now like the Ion lasers as it is always in a lasing state.

1ST off -- Thats a nice looking projector! There is also such good info on safety in the thread.

2nd -- I would like to ask some enclosure / safety questions while everyone is on the subject. Sorry If I am hi-jacking the thread, I can take my questions to a new one if requested. Not looking for any detailed answers, just opinions.

I like the simplicity of the enclosure, I will be using that same design to build my own projector as I work in a machine shop and have access to everything needed including anodizing. I could not tell from the picture but what is it sitting on? I saw it was raised up from the baseplate but I could not tell what was under it.

I plan on installing key safety features such as key interlock, case interlock, emission indicator light, beam shutter and emergency stop. Mainly to just have a safe device but with the idea of eventually getting it approved for show use in the US.

Will using that design help me get my projector varienced if I attempt to do so? Will me building my own blu-ray and red laser modules cause me more trouble to get my projector varianced than using lets say, laserwave modules (that's what will be going into my scanner) ?

thats actually a really interesting question, if you cloned the OSLS design exactly down the the stickers/screws etc(besides pissing off OSLS) could you variance it just the same?

Misterwilling-

Not hijacking anything! This thread didnt go the way i intended it to go, lol, but it did bring about some very useful informatioin. So, no need to apologize!

I could not tell from the picture but what is it sitting on?

Im not 100% sure what you are refering to. the black thing the laser itself is mounted to? or the Table looking thing the whole projector is on top of? The black thing is just the bottom optical plate drilled and tapped 1/4-20 on 1" centers. The table looking thing is just a cheap saw horse type of table i bought at Home depot. nothing fancy.

It satisfies all requirements and provides *extra* safety features also. However, every design and product report is still done the exact same and goes through the same process. The only thing that technically makes the process go faster for you is to use an already certified enclosure (like the one pictured here in my post)

Will me building my own blu-ray and red laser modules cause me more trouble to get my projector varianced than using lets say, laserwave modules (that's what will be going into my scanner)

Nope. doesnt matter at all. As long as your finished product satisfies all of the required safety features, you can have toasters and death rays in your projector and get it varianced, as long as the end product fullfills the safety limitations.

Using a pre-certified projector saves the hassles and EXTREME time delays of filing the initial product report. the initial product report is already completed for pre-certified systems which outline what can be built into them and how it can be built into them. These days, it is an extremely broad spectrum and covers 95% of what you could build into a laser these days.

thats actually a really interesting question, if you cloned the OSLS design exactly down the the stickers/screws etc(besides pissing off OSLS) could you variance it just the same?

Actually, its stealing. At that point, you are making an exact copy of their work which is theirs and i am sure it is criminal. in order for it to be certified already you are claiming its an LT1000 and would be using its accession #. If it isnt their enclosure, than it isnt their accession #.

My Intention was not to exactly copy the OSLS and pretend it was, just use the same style design so I don't have to come up with my own. I know they can get mad it I bolt two plates together with angle as long as I don't clame it to be an OSLS or sell my own enclosures/projectors.

I attached a picture to show what I was talking about with what the baseplate is sitting on. Do you know off hand the thickness of the angles? I looks about .25" thick per web.

I am in no rush with my projector since it is my first. Maybe I can get it built and file the paper work as soon as its done. I will need some help from you guys when I get to that point. Then as I wait for it to be completed, I can figure out how to use it, write some shows and save up for Pangolin quick show.

Thanks for your answers.

thats just 1"x1" aluminum square tubing so that your bolts have some where to go

basically it holds up the deck so when your bolts from the bread board go through the projector still sits level

Austin,

I know your question was intended for Marc but I own an LT1000 as well. The base in your picture is 1" Square Tube.

well I doubt you can copyright/patent a box (although nothing would surprise me) but then using their accession # would probably be the sticky part

and honestly I think them charging $2500 for an aluminum box is extortion to begin with
