hey tbob,
if you could see this link www.ni.com/india and see the VI mantra page there u will sure be enlightened by GOD himself..

This is starting to sound akin to the 5th dimension, for those in the know.

tbob asked "Anyone remember the guy who used Labview to create God? "

YES!

He escaped to the Fifth Dimension and has bee leading (?) the most popular thread on LAVA.

Want a nice project? here is one:

few weeks ago i went for the first time to the casino here in Innsbruck, and played Black Jack. however they shuffled the cards all the time on a six pack, automatically.

So here is the deal: make a simulation of a Black jack game, in cases one pack is used, 4 packs with 1/6 of the cards not played (las vegas rule), and a 6-pack fully shuffled at all time. tell me if i have any advantage on the house, using card-counting methods 🙂

thats probably a CLD level one 🙂

AK2DM you are scaring me.

I already question my sanity when it seems that I am the only person that understands Alfa.

Ben:

I just knew we'd be hearing from you soon regarding that, maybe our little parallel universes have the ability to intersect!

I apologize if your thread is getting off topic, sorry I have no suggestions for your simulation project.

hey ak2dm,
perhaps you could tell me some project which u did in labview when you started off as an amateur..

Uhhh... he still is an amateur   (I know he'll get me back somehow)

My first project in LabVIEW was a Cylindrical Lens Inspection Test System.

It's purpose was to inspect cylindrical lenses used in scanning print engines that create high resolution film images of XRay and CAT scans. Defects in the lens substrate and coatings on the order of 10um and larger would create unnaceptable artifacts in developed film images. It was very difficult for an assembler or technician to locate such defects by eye, even with the aid of optical magnification. Only after the entire engine was assembled in a cleanroom and test films were ran were they able to realize they had used a defective lens. Installation and re-alignment of the optics and another lens was time consuming and laborious.

To detect defects automatically, a stabilized laser beam was focused onto the lens and the ouput beam was monitored by a high speed photodiode whose signal was was converted to a voltage by a transimpedance amplifier. This voltage was fed into a DAQ card. A defect would scatter the beam and cause a change in voltage.The lens was then traversed in the X and Y axis by motorized stages that were controlled via LabVIEW. The photodiode signal was simultaneously acquired. Additional code was written based on differentiation to store the voltage data for each scan and process it to identify potential defects.

The XY position and ranking of defects were recorded and graphically displayed, and the system was able to screen out lenses that had pits, scratches and other various defects. It was also possible to identify lenses that had uneven coating thicknesses and poor grinding geometry of the lenses' glass substrate. Thses two issues were not even known to us until the LabVIEW based system was used. Overall, it was a very interesting prjoect that was quite successful and beneficial to my company and our lens supplier.

Hope this enlightens you!

Oooooh, ak2dm is not an amateur!!!!

Here is another idea.  Touch sensors are becoming more and more popular.  The ipod is an example.  Thin membrane keyboards and the touch sensor on a laptop is another example.  You can use Labview to test and calibrate these sensors.  They work off the principle that touching or putting a finger very close to a metal plate changes the capacitance.  Touch lamps work on this principle.  You could write a paper and use Labview to sense the touching of a sensor.  You need to use hardware equipment to generate a signal to the sensor, and then send a pulse that would simulate touching the sensor.  Look at the resulting waveform and you can see the point in time where the sensor was touched.  The capacitance changes by a very tiny amount, picofarads.  This would be a great challange.
