EyeFi & the Online Classroom

December 3, 2007

While trying to find the perfect gift for a digital photographer, I stumbled upon EyeFi.


    I don’t think the website does a good job of showing it’s potential. Instead, I got hooked by the Today Show segment.

    This could be a really easy way to post pictures of your classes. Have a “classroom camera” with an eyefi sd card to automatically upload pictures to a classroom blog.

    As a technology teacher, a lot of what I do in the classroom is interesting to look at. I may try this next year.


    Thermal Copier

    November 28, 2007

    While setting up a new project for the Graphic Communication Technologies class, the school’s (only remaining) Thermal Imager broke. A call to the manufacturer’s support line confirmed that nobody knows what a “thermal copier” is any more.

    No manufacturers make Thermofaxes or Vistafaxes anymore, and schools/companies have long ago thrown out the outdated machines. I need one for my classes’ screen printing projects – it makes use of the machine for a different purpose than it was intended for. I have set up a page about recreating/fixing/making a Thermal Copier.

    Anyone doing Screen Printing (or even Tattoo artists) might be interested as well. Tattoo artists are another niche industry which has found an alternative use for these machines.

    Screen Printing

    June 19, 2007

    To teach Printing Technologies I’m going to try a screen printing project.   I think students would enjoy doing silk screen printing.  Students would design and print their own t-shirts/bags/etc.  (One possible alternative project would be producing a stamp as a form of printing.)

    The Thermal Screen Printing Process can greatly simplify the screen making process:

    A special kind of screen is used.  Instead of stretching silk on a frame, spreading light-sensitive emulsion, drying, and exposing; all you have to do is get a laser print out of the design and run it through a thermal copier with the special screen.

    Canon Powershot Cameras

    March 1, 2007

    In the Graphic Communication Technologies class, students us a class set of digital cameras.  We have 10 Canon Powershot A510/A520/A530/A560 cameras.  This is a decent budget friendly point-and-shoot camera series.  Someone discovered the cameras’ firmware is hiding some of the better features reserved for higher-ticket cameras.  But not anymore..

    Currently, the cameras already do everything my students need them for.  The feature of CHDK hacking that interests me is the Splash Screen Branding.  I would like to change the start-up screen on the cameras to show that it belongs to the school.
