Hallo


With this report I would like to present my scan equipment to you.
For some time I am working with the David scanner, my scanner scans are very good and I use the data for milling.

I hardly use the laser, because the SL scanning provides beautiful und fast results.
Since I wanted to simplify the steps I've built a remote control, which makes several steps easier. Now it is possible to scan from the PC or remote control.
Furthermore, a turntable is driven to be able to pivot and move.
The remote control and the turntable are controlled by an Arduino Uno communicating with the PC and David.
The software for the Arduino is http://wiki.david-3d.com/the_open_hardware_project of David "The Open Hardware project."
I have rewritten the software for my personal needs. It was very hard work, as my programming skills are very low limited. The software now works error free with the remote control.

Now I will tell you the scan sequence with the remote control.
Calibration of the camera and projector and then switch in the "Light Structures
Folder " (switch .)
1 ) On the remote, press " START SCAN " .
The scan is performed.
2 ) Press the button "LIST AND TABLE"
The scan is listed and Turnable motor rotates the object 45 degrees
further .
3 ) A beep sounds, indicating that this scan is complete

This operation is carried out 8 times , and the object is completely scanned.
The advantage is that I can always stay with the object and not always with the mouse or the keys have to click around on the PC.
Important for scanning objects which are valuable and are rotated by the motor.
The fusion is carried out in a conventional manner .

With the key " relief" following happens .
1 ) , the scanning head is created as described above and the object is rotated further by 45 degrees CCW .
2 ) The second Scan is made as described above.
3 ) Next, push the " relief" button and the turnable motor rotates the object by 135 degrees CW .
4 ) The third scan is made and the object is again rotated 45 degrees CCW and returns to its normal Position.
Usually only 3 scans are needed for a relief.

I’ll try to change the software further, becausesoftware further, because should once the merger be automated, David will be the first choice.

The rig, also constructed by me for my camera and projector, is very helpful
This rig can be installed vertically or horizontally.
All angles for all object sizes can be adjusted infinitely variable.a recording for conversion lenses . Now I can approach the object up to 40 mm-
Therefore I use 2 Logitech 9000 Kameras. One of them I have rebuilt with a zoom lens. Caution !! If the optics of the platinum of the Logitech is removed, the infrared filter will be missed and the colours are completely distorted.
Therefore I have dismantled a defective camera and built out the infrared filter and placed it on the sensor of the Logitech 9000.
Now the colours a super again.
As a third camera I use the Canon 600D.

"ATTENTION" ! Very important is the grounding of the tripod to the ground of the Arduino and the main ground .
When I didn’t have the grounding the Arduine temporarily lost its COM connection or the computer crashed. The PC had to be restarted. These errors are now never occurred again .These errors never occurred again.

Regards Egon

Hi mexscan
really like the dial. The milling precision work, I also worked with foam.
We are neighbors. :wink:

Regarding Tibor's link above:

3D Creations is using the DAVID software and don't mention it. Really strange! :oops:

@WalterMo: Thought the same thing. Though I did find myself a little flattered to see that they were using my Dell M110 Projector lens mod. :D

HI

I would like to introduce you to my newest equipment.
When I saw the beautiful scans of Christian Mendes
which he did with a rebuilt trust webcam, I also wanted to achieve a better quality of my scans.
I rebuilt a trust webcam for my CS lens, and can use
either the Logitech 9000 or the trust webcam with this lens. The trust cam makes very good scans.

I have converted an old broken analog SLR camera “Miranda EE” into a Web cam.
Everything was removed so that only the empty housing for the
optics 50mm and 35mm is left .
The Board of the Logitech 9000 Web cam is mounted into the housing so that the surface of the Web cam sensor on the surface of the original film is in line.
The infrared filter was removed from a defective Sony DSLR
which you can bid on eBay for approx. 2 EUR. Attach the filter in front of the sensor. Works perfectly.
Caution: When dismanteling the digital camera make sure that the contacts of the Flash capacitor will not be touched.
The Elko could be loaded with 500 volts. (Previously discharged through a resistor. No short circuit.)


The 50mm lens has great advantages for macro scans.
1.)
The depth of focus is much easier to adjust. When the object rotation is not exactly in the Center, it is still in focus.
For my 20mm Panel the projector is approximately 100 mm away from the object.
Due to the telephoto effect of the 50 mm lens the camera can be installed approx. 400 mm behind the projector and therefor don’t mutually interfere.
2.)
The light intensity of the lensis is higher than that of the CS lenses and of top quality.

David scanner automatic
The electronics for the turntable has been rebuilt for David Scan Automatic engine
(Arduino UNO, Pololu A4988, LCD display TC1602E-01, stepper 2A laptop power supply 18 volts.)
I use "Turntable_Leo2_2" as software.
Scanning, turntable, and save are running according to the setting
8.10 or 16 automatically times out.

Egon

Hi Egon,

Good work, the self-built hardware and the scan results!

A question: The aluminum button on your controller, what is its function?

Hi Walter,

That was the potentiometer for the
laser scanning.
Has no function.
