Just purchased a laser line pointer
« on: November 27, 2007, 09:32:49 PM »
I got it from ebay and it looked small and compact.   Other folks on a laser scanner forum recommended this product.

I'm looking forward to doing some scanning.   I do have a laser level, but its just to big and the line width seems to wide for accuracy.

What are you using for a power supply?

I also purchased from the same guy a 3.2 volt wall wart.   I could have used a single LIPO 123 battery, but I took the easy way and bought the wall wart. 
Gosh, I have so many wall warts in my basement, I could've probably found one instead of buying it, but it just so happens that I did a search for wall warts last weekend on another EE project and I don't remember running across a 3.2 volt supply.  So I pulled the trigger on this purchase too.

Thanks David.  I've been wanting to do some 3D scanning ever since I saw the Nextengine scanner but didn't want to put out that kind of money just to start playing around.  Saw the David set up and bought a Micro$oft Life Cam VX 6000, it may be over-kill and may not work at all, BUT I could not find a good laser pointer and this may just be the thing to get.  The price is good.

I'll get this set up and then look for software.  (OUCH!!!) That's where you really get killed.  Any ideas?  I bought MACH3 so I've got that piece in place.  I've got a new CNC machine in the build and a PC ready to be connected up.  Would be fun to play with until the machine is finished.  Next, we'll need a way to stitch the scans together for full 3D milling.  ART????  are you listening?  :D

Just downloaded Art's new plug in.  This is going to be fun!

What's the difference between the 650 nm and the 635 nm line generators?

I believe the difference is color.

look on the second page for color distinctions.

How do L.E.D.s and Laser compare?  I'm lost now.  :)

I already said more then I should.  Here's what I'm guessing to be your answer. 

You will use a laser because it shines brighter and can be focused in a line.  Any focused light source can be used, but the little lasers line projectors have the best focusing.
 
The 650 nm is the color's wave length in Nanometers.   Each color has a different frequency (different number).  Any color would work, but I'm using the red because it's there.   

I'll let some smarter guys chime in and correct us both. 

Here's a question for Art:   For a red laser, what are the recommended settings set in your software.   Contrast? Hue? Brightness?    What is your recommended color for this project?

Dave,

As far as I'm concerned anything given in information is GREAT and if it's not right I'm sure someone will chime in.  :)  What you said makes sense to me.  So go on and give your view.

I'll be ordering today and see if I can get to play with it next week-end.  How has yours worked out?

Thanks,
Greg
