    Beau, That is amazing!

    That guy really does have "The Right Stuff" geekwize.

    When I see stuff like this I really hate the fact that I have no
    mechanical skills... no way I will ever be able to pull something
    like that off. I can do cool stuff in code but not in hardware.

    I really hate having this limitation :-(

    Thanks for posting this interesting story....

    Wow, that is impressive! It's hard to fathom the amount of work that went into it. I thought the tiki torch leaning against the wall behind the device added a nice touch, too. :)

    That really is impressive. Also reminiscent of some of the early instruments I worked on.

    A true DIYer... Making everything from layered wooden bowls and beer taps in the living room, to the SEM. Also, according to comments he made in his SEM post, he's a Propeller user!

    "Foxs, this was my first plan. I originally wanted to use a microprocessor to generate the raster scan pattern and capture the data for storage/display on an LCD. I may still do this, but there are a few problems: finding a microprocessor with enough RAM to store the image matrix, using a DAC to generate the raster scan pattern at live video rates, and interfacing with a nice LCD (ie generate SVGA video). The Parallax Propeller seems like it might work, but needs a lot of development. Have you handled live video with a microprocessor or USB device? "

    Great Find Beau.

    Thanks for the link. I'm going to google this. I think he raises the standard to qualify as a geek.
