Using ViewPort to Make a 3D Laser Scanner

I haven't done this yet... but with the gift of sight for your propeller (Viewport) , a line following algorithm, a wine glass, a laser pointer and a little trig you can.

have a look here

    I did this actually, but to grab the 3d info off of the scan you need a powerful computer.

    Also its hard with a wine glass, a Laser Level which provides a straight line works better imo.

    I only watched the first bit of the video, but the fellow seemed to be a bit too relaxed about laser beams on his face. Was eye safety mentioned at all? Green lasers pack quite a punch, especially the newer Class III systems. There is a serious risk associated with damaged or misaligned doubling crystals in these cheap systems, which would leak significant quantities of the IR fundamental light through, at much higher power densities than the specified visible output powers.

    Cheers!

    Very interesting project! Should be easy to do this with ViewPort. I'll give it a go once I finish the bug fix release, development kit and sending out upgrade licenses... I wish I had whole departments to hand projects of to like partsman123...

    now there is a feature I would buy ViewPort for. Assuming I could get the output in some format usable in image software.

    Need to make your prop design easier or secure? Get a PropMod has crystal, eeprom, and programing header in a 40 pin dip 0.7" pitch module with uSD reader, and RTC options.

    by the way 3:44 into the video they explain they have special contacts to protect there eyes.

    mctrivia,

    I believe the rest of the video... but I just have trouble believing the contact lens story... I think it was to encourage people to be careful and to cover up the fact that the only think he really did was to tell his mom to keep her eyes shut[noparse]:)[/noparse]

    Hanno,

    It is pretty hard to delegate creative genius. It is very rare and no-one knows how to bottle it or scan for it... it just kind of pops up from time to time.

    From my search it seems that the ADC08100 is surface mount only... is that correct?

    Being the clutz that I am, I looked for a breakout board for the ADC08100... there doesn't seem to be one. I looked at the mechanical design of the chip... and I think I could work with it.

    In your Circuit Cellar article, you show what looks like a hand wired board. Is this in the product development stage?
    Can you offer any more details or suggestions for implementing the adc08100 design?

    Bigger pictures?

    Would you please use your clout to get Parallax to handle this chip at least for a limited time... they don't have to do anything else, but this chip is a dandy and I don't want to go anywhere else just to buy one[noparse]:)[/noparse]

    Thanks,

    Rich

    I realised don't need view port for this. just a digital video camera and matlab which I already have.

    Rjo-
    Yes, the ADC08100 is pretty small. The schematic in the article should help you figure out which pin goes where. My dad gave me the inspiration to mount the chip upside down with some "blutack"- think "chewing gum". Then (as long as you flip all the connections correctly!) it's pretty easy to wire it- I used very thin wire. Bryan, from ucontroller.com is putting together an "IODreamkit": Propeller+8100ADC+DAC's+input and outputs! He's done an awesome job with his other boards- look for it soon. Also, I'm working with Parallax on the PropScope- high speed oscilloscope, logic analyzer and function generator- all powered by ViewPort and the Propeller. Lot's of great stuff coming soon!

    Hanno,

    I've been underwater with other things... but I didn't want to let this thread go without commenting about your budding infra-structure. I personally could not have suggested a better relationship than the one you are forging with SpinStudio.
    Although not quite a marriage, this is a cooperative step in the right direction, which should open up wonderful opportunities for all of us, as well as for the main actors.

    We all want to make the best use of our creations. Sometimes the most difficult issue is what to do with what we have already done. Your move in this direction says volumes about your character and your vision.

    Well done.

    Rich
