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

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:
All Position Detector specifications apply with Cambridge Technology servo driver after a 30 second warm-up All angles are in mechanical degrees. Consult manual for complete operating instructions.

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?

•         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.

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.

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.

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.
