FLECOM's LaserScope projector: Another perpetual Work In Progress...

[flecom]

yes, another laserscope thread... hopefully this one will have less dahrma (TM)

this is going to be a worklog for my laserscope based projector, its going to be a long journey since it honestly wasn't part of my plan to ever do a laserscope projector, since quite frankly it scares the beejeezus out of me, but it just kind of fell on my lap at a price I couldn't say no to lol

it needs a new KTP and oven controller, the KTP thats in it is not in great shape, and its got a non-gold box oven controller which probably isnt working ideally

heres its current state - which I received it in...



optical deck, most of the medical optics have been removed, there was an extra shutter installed before the attenuator also...



powersupply for the lamp, and powersupply for the Q-Switch driver, the Q-Switch driver amp is going to change to another +24v psu I have from a low-power microwave SCATA data link



heres the cooling setup, I think all of this is from the original laserscope, going to be changing this obviously as part of the "grand plan"... mostly just a test jig...



close up... everything here is 240v... on those terminal strips - currently exposed(!)... thats obviously not going to stay like that



filter... a certain prodj told me this was supposed to be a milky green/brown color... for some reason mine is all clear? weird huh?



here it is fired up without the Q-Switch... cant remember the current I had it running at, but it was fairly low... this was probably 200~300mW of 532nm... have not measured actual output yet





heres with the Q-Switch on... probably making a few watts



uncollimated dot... you cant see it but its 4 individual dots (multimode)

so basically the plan is to make a beamtable with a set of XYZ scanners at the end also... while having multiple safety's (shutters/contactors/disconnects/flow switch/water temperature monitoring/interlocks on any panel where laser light could be visible/etc)

for the sake of size I am thinking of having a separate PSU/cooling/control unit, and then the projector itself with the laser/actuators/scanners etc

I am also not sure if I want to build the optical table on the existing optical table, or if I want to shoot them beam straight up from the laserscope optical table to a proper beam table (breadboard) on top of the laserscope table... I could have sworn I have seen a projector where somebody did this and of course I cant find it now lol

like I said in the beginning, this is probably going to be a long journey since honestly, I have no idea what the heck I would do with it when I am done! lol

even if I do eventually finish and variance it (which is the plan), this thing is so bright I couldn't imagine using it for any kind of indoor venue, nor do I see myself ever having any stadium shows, so I guess I will have the ultimate electrical tape slicer? LOL

feel free to comment/flame/share ideas etc...

well is this what you are talking about?

hey fle -

First, a quick 'leftover' from the 'other thread' -

ya seriously the first time we complained about the RGB lasers being not even close to aligned and the scanners couldn't even do an ILDA test pattern at 12K their response was (I swear to god) "ya, we hoped you wouldn't notice that"

WOW - that's terrible!.... and 12K? How do you guys even play any shows off ADAT with that performance? Most bought-shows I know-of would be at least 30K (ISP) optmized....
Does the PT have any 'recourse'? Sheesh... that sux...

filter... a certain prodj told me this was supposed to be a milky green/brown color... for some reason mine is all clear? weird huh?

Uh, yeah - First piece of advice - don't trust ANYTHING that hack 'tells you'... there should be NO 'green' or 'milk' - the 'DI' material in that cartridge should look like that course-granular 'raw' cane sugar - a nice, 'sandy-blond' color... any 'green', would probably be algae / mold... not-exactly what you want pumping thru your cavity...

I am also not sure if I want to build the optical table on the existing optical table, or if I want to shoot them beam straight up from the laserscope optical table to a proper beam table (breadboard) on top of the laserscope table...

The question is: galvos-only; galvos + fiber-launchers; or, 'the works'... IF you want 'galvos-only', then the deck is probably enough space... and fyi - you could get rid-of a lot more 'crap' on that deck, still, and have more space...

If you want fiber-launchers (for remotes - the 'way-to-go' for indoor gigs... ) and/or beam-positions you'll wanna 'spread-out' on a table-top... here's one 'design', base-off implementing some old Lasermedia turrets... (...side-panels removed for pic...)



..anyhoo, continue-to demonstrate yourself to be 'smart' (ie: we don't wanna see any videos of you sticking 'chrome-plated pliers' in the beam, when doing 'roach-toasting'... or - this kind of 'darwin-awardesque brilliance' - http://www.youtube.com/watch?v=t65_JJrLFZ8 (!!) - and you'll have all the 'help' you need / want... capeach?

looking forward to your ideas...
peace...

yes I knew I had seen that somewhere here! the complete projector... did you ever sell that beam table?

Thread needs more pics of burning

hrmm, ok

First, a quick 'leftover' from the 'other thread'

basically the 12/30k ILDA test dosent look "OK" until you turn it down to like 12K~... their ADAT tapes are recorded at 24k (these are OLD, OLD tapes) so they generally look "OK"... some of the shows I have made I have had to replace effects becuase the scanners start oscillating during certain effects/patterns... and mind you this is supposed to have Cambridge scanners according to their website!

Uh, yeah - First piece of advice - don't trust ANYTHING that hack 'tells you'... there should be NO 'green' or 'milk' - the 'DI' material in that cartridge should look like that course-granular 'raw' cane sugar - a nice, 'sandy-blond' color... any 'green', would probably be algae / mold... not-exactly what you want pumping thru your cavity...

I was just joking I assure you

I have worked on several watercooled electronic devices (never a laser tho) so I am pretty ok with it I think

thats a pretty sweet setup, I think I want to do the works on it... figure beam table + scanners... maybe a fiber launcher for a remote head if its used indoors...

ya dont worry, I value my eyesight a lot, whenever this this is powered I have goggles on... I use insulated (Klien 1000V+) when working on the electrical bits... and whenever I am playing with the optics I have the Q-Switch off and the powersupply for the Q-Switch unplugged so it cannot fire by accident, along with low lamp current, so its making less green than some pointers I have seen hrmmm lol...

one of the neat things I have discovered is just how much range of brightness this thing has... running it at ~15A without the Q-switch its probably making a few hundred mW at most, barely enough to keep the lamp running CW... turn the Q-Switch on and its making, maybe a bit more than a watt or so... but turn the current up, and then turn the Q-Switch on and oh boy does this thing get hella-bright!!! and its not even in good enough condition to really make more than 10W at max current (KTP needs love) so I cant imagine what 40+W would look like!

one of the things that really terrifies me is IR... do these things leak a lot of IR if everything is operating normally?

[Laserman532]

the only IR leakage is right at the output, the prism will deflect the ir into the ir blocking thing and only green should propagate out the collimating lens.

I have that projector but it would be pricey to purchase as is, it has everything (except fiber) 12 gm20 dual positions with full optics splitters 30 or so mm-1s with mounts and its associated yada yada and electronics and cambridge 6850 scanner pairs with amps and yada yada, ready to bolt onto a laserscope and I have the beam jogging and beam uprouting optics. As with a price tag complete of around 6k...no one will buy it...so it i will meet the wreaking ball here soon. Sad, but oh well, I have spent years collecting this stuff and now I am spending years getting rid of the stuff.

actually I was asking about the optical table itself you linked to in the FS forum

[dsli_jon]

...so I cant imagine what 40+W would look like!

...meahh, sometin' like 'dis...



...you're 'inspired', now, arent' you?

...Oh, sorry, almost forgot...



...and Pat's got some really killer-shots from a Moto-x... ...Maestro? ...

As with a price tag complete of around 6k...no one will buy it...

Really?? ...PM-send pending post, here...

fle - I would say, go take out a small loan and BUY Pats' kickin' table, ASAP - a STEAL at that price....but I want it, so back-off, man!!

peace..

[Laserman532]

actually I was asking about the optical table itself you linked to in the FS forum

I sold that one to vjawaz (or what ever it is) I was in fund raising mode so it went cheap, I have another one i could sell you for $1.25 per hole which is also a deal (not as good as his deal, but anyway...)

so 300 holes @ 1.25 = $375.00 and it is heavy so add $25 for shipping and it is an even $400.00

(i know I paid well over 500 for it by the time it was machined and anodized)

I would need a day or two to take off the two sets of g-120pd mounted to it (it was my second projector)

This table bolts directly to the standoffs provided (with most laserscopes) that go through the top of the plastic inner covers.

this is for anyone who wants it should flecom decide to decline.

No intent to hijack this thread...
But how on earth you gonna use this equipment for shows?

I thought my Datronik system was big

Ah well, have fun... as long it's not linked to a certain ProDJ
