Hello my dear laser friends ;)
My name is Ferry, living in the north-west of the netherlands.
Some 20 years ago i saw a laser system which i couldn't buy, untill a week ago.
I saw a add on a local marketplace for a Datronik club laser.
Realy got it for under 200$ and it supposed to be broken.
Well now, i reconnected all wires and it works...
It has a 40 mW HeNe and a 400 mW Argon laser....
I include some pictures (not Hi Q)
Next week i pick up a PCAOM driver and some Cambridge scanners.
Also i thank James for building me a nice DAC set :P
-
I'd add to that Skype is pretty awesome!
We had a very nice conversation.
He's got about $100K dollars of 1988 laser equipment there.
Apparently he's also very fortunate to live where 220V single phase AC requires no special house wiring.
The only problem is that all of it is bound together as one single unit that is fairly large and probably about 150 lbs.
Check it out! He's got a whole row of actuators with color filters and mirrors, two overlapping lumia wheels, diffraction gratings, a dual motor Spirograph thingy and a whole bunch of MM1s with mirrors to bounce the pick-off beams into the effects optics.
Have you shined your laser through any of your diffraction gratings?
James. :)

i hate you
-
Who... James or me? O0
-
He hates YOU because you got dream-come-true laser system for almost nothing.
I don't hate anyone.
BTW I forgot to say....
Welcome to The LaserBoy Forum!
James. :)
-
Welcome new guy. For the record, I am a lover not a hater.
-
i hate you
You must understand BlinkenLights is a real trouble maker. He gives everyone here a hard time. That's about the only reason he ever posts anything. He's a doosh! (His spelling. Not mine.) He's also the guy who set-up the forum and he and I are the admins.
If you ever meet him, get in line to kick his ass.
James. :)
-
i hate you too :)

Who you gonna hate now? :P
Don't want to be offtopic, but check these laserforum anims....
I am meeting the crew next week...
This is just fantastic ;D
-
Hello and welcome! nice system you have picked up there, its main capability is somewhat removed from what we see in those laserforum animations. Laserforum makes some great stuff with the Lasergraph DSP, take some pics when you meet, I'd like to see the group myself :)
-
Thats a great projector. You are big time now. It reminds me of what I used to work with at Sea World.
Welcome
-
I think that's got the cheap China projector beat. ;D
-
Plus this guy is really cool too. I've had fun getting to know him on Skype.
He knows what he is doing and there is a good reason why he got this amazing projector.
James. :)
-
James, we don't agree on a whole lot on here but you're a good dude.
-
I like you too, Gary. ;D
James. :)
-
oh god.. why don't you two just get married and adopt a kid Haiti...
-
Oh my gawd.... well humor is important ;D
Here some pics from the scanning unit and amps....
Scanning was done on a pangolin system @12K
-
Ramp that puppy up to 30K.
Lets see what it can really do....

I don't have them yet...
When i do, i sure will
BTW here are the spec's:
Used complete XY Datronic 6800 scanner-amplifier system laser
Used in 14,5†case, XY scanner-Datronic system and used XY 6800 scanners in working and good condition. But think about it, this are not new scanners. Ideal for Pangolin or other users, the most wanted laser projector. You will see the quality of the scanners at the test picture, for second-hand scanners this are beautiful pictures, scanned at standard 12K on Pangolin. The system will be delivered with an original Datronic amplifier and pact in original box.
Y scanner has a little overshoot.
Specifications amplifier:
• Datronic amplifier.
• Power 220-230 Volt
• Scanner protection.
• In- and output safety shutter.
• Each amplifier has his own power support.
• Input signal 15 p. sub-d female.
• Possible to hardware Invert X / Invert Y.
• No XY, 2.7 meters cables scanners.
• No scanner holder.
• For scanner speed max. between 12 and 17K.
Specifications scanners:

WOW! That is a really nice set of scanners and controller.
I've never seen a controller amp so big and well built!
I'm not sure how critical it is, but you might have some issues replacing the scanner cables. There are high current wires in there to drive the scanners and also wires to return to the negative feedback loop of the amp for precise position of the rotor. There my be some specific impedance and capacitance issues that you need to match. I don't know. Anyone else know?
James. :)
-
Why you think i have to replace them James?
-
• No XY, 2.7 meters cables scanners.
• No scanner holder.
I think both ends are common connectors. The amp end is like a 9 pin serial port and the scanner end is a .10 inch spaced, double row, pin header.
James. :)
-
Aha... well i get it complete with a replacement mount...
Let's continue the chat on skype? drlava is also here ;)
-
OK!
I just got a huge cup of coffee and I need to take a minute to get my stuff togther. Talk to you soon!
James. :)
-
This is what I have so far.
I need to do some coding before I get the small capital letters along the botton to slant to the right. I will probably make a new ILDA font file for Arial too.
James. :)
-
Thanks James!
Beginning to understand some of the commands in laserboy now...
Can't wait to see some vectors outputing from the laser
-
Received the 6800HP galvo's and the PCAOM Driver.
Sadly enough the mirror on the Y scanner was broken during transportation.
A new one will arrive soon :)
Here a pic of my 2nd opticaltable, here i place the galvo's and some mirrors who redirect the waste beam for use in my 1st opticaltable...
Can't wait to get the Laserboy DAC.
-
I can't wait to make it for you!
I don't understand why my first order of parts came in about a week. This next order seems to be taking forever.
Oh well. since a few other people want them too, I have ordered more parts than I need from a totally different source. So, one way or another, it will come together. I hate to do nothing but wait! And I hate to make other people wait.
James. :)
-
By the way, if you look close enough, you'll see i succeeded in removing the chunk of mirror wich whas inside the rotorshaft.
-
I noticed that! ;D
I just got your 8 channel sound card today. I have three more on the way.
James. :)
-
Tweaking and phreaking time ;)
Got the holes drilled into the baseplate so i can easy adjust the scanner mounts.
-

James. :)
Does this mean I can buy a DC/DC converter from you?
-
I have some left, yes.
+5VDC to +/- 9VDC.
Call me sometime!
James. :)
-
Call me sometime!
Why not call all of us?
I'm allready waiting for some laserists comming to skype :P
-
Do you want me to work on your DAC, work on LaserBoy code or spend all day talking on Skype? ;D
James. :)
-
I will shut up..... >:D
-
Just kidding!
Sound card hacked!
Now cutting holes in the plastic box for the amp!
Listening to The Best of ELP.
I'll probably pop in Focus just to get pumped up. ;D
How are things going with you?
James. :)
-
Waiting on that mirror....
Further i am a bit dissapointed in the beam quality leaving the PCAOM.
Maybe i have to fine tune, but there some functions on the remote i don't understand yet.
Gonna mail the factory tomorrow.
-
Did you get the AR glass windows to seal up the PCAOM box?
James. :)
-
Did you get the AR glass windows to seal up the PCAOM box?
James. :)
there's no glass in at all....
tho i just got some high grade accetone
-
Check it out!
This one is for you.
Now I have to sit here with an ohm meter and measure out sets of close matched resisters for the amps.
James. :)
-
James,
How come his looks cooler and less "Unicorn and Rainbows" than mine?
LOL
Looks great you are getting really good at this.
-
LOL thats like the chinese knockoff version compared to my signed original..
-
I have to deal with whatever box I can get.
Yours is Aluminum! ;D
Don't worry, I'll make it look totally gay before I send it out.
All of the ones I make are signed originals.
James. :)
-
im sure it functions as promised and will look hella gay at ship time..
-
This is the works!!!
Looking gay enough :P
-
but will it be as gay as the one i have
plus mine is serial 001 of the 8ch version (hand wrapped board and signed)
-
Here is mine:
-
Well mine is on it's way...
James sended it out yesterday.
In the meantime i found out that one of my galvo amp's was faulty.
After some measurements it appeared to be a blown diode.
Replaced the little sucker and fired the amps up with succes :)
Also i wired everything up to ilda specs so i'm good to go when the DAC arrives here.

DUDE!
THAT'S AWESOME !!! ;D ;D ;D
Now you know Rule #1 AND Rule #2! ;)
James. :)
-
Now you know Rule #1 AND Rule #2! ;)
As in No.1 Lasers don't work and No.2 Ferry always fixes it? :P
-
You ARE a very smart man! ;D
James. :)
-
BTW, i'm looking for a DMX receiver/decoder board.
I want to use it to steer my actuators and zo on at the opticalbench.
Any of you know a good kit?
Ferry
