  • This is very cool project! Thank you for posting and sharing your design ideas. As one who has also spend more time than I want to admit thinking about this problem, I thought I would throw out another option you might be interested in exploring--if you already haven't. Instead of using a 3d printer, caste them in dental plaster. It is a very inexpensive route if your goal is to produce a large number of tiles in a relatively short amount of time. You will end up with a very high quality product that is easy to paint and mod--add LEDs, etc.. But you do need molds. I've used the ones at Hirst Arts (http://www.hirstarts.com/). They are awesome molds and his tutorials are great. You could also take your current work in this direction, by using the 3d printer to create the positive, then make your own molds in silicone for dental plaster casting. You end up with tiles that feel like rock instead of plastic, and I think the cost per tile would be far less in both time and material.

  • After trying Ubilinux, I found that I needed to go back to Yocto. If anyone else finds themselves in this position, I wanted to share a discovery that took the pain out of living with Yocto.

    The package installer opkg can install all sorts of common packages, but you need to add a couple of repos.

    This post give the details: https://scivision.co/getting-started-with-intel-edison/

    From the link:

    Add Unofficial Repository
    
    vi /etc/opkg/base-feeds.conf
    and paste in
    
    src/gz all http://repo.opkg.net/edison/repo/all
    src/gz edison http://repo.opkg.net/edison/repo/edison
    src/gz core2-32 http://repo.opkg.net/edison/repo/core2-32
    
    Then hit your Escape key and type
    
    :wq
    
    to exit and save the file ( you forgot how to use vi, didn’t you)
    
    Now I have access to many precompiled programs. The core2-32 directory currently holds the ones you might recognize.
    For example:
    
    opkg update
    opkg install nano
    
  • I had this problem too. I found out on the Intel forum somewhere that it depends on your version of mraa...

    Earlier version use:

    export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7/site-packages/
    

    Later versions use:

    export PYTHONPATH=$PYTHONPATH:/usr/lib/i386-linux-gnu/python2.7/site-packages/
    

    For me running:

    find /usr/local -name mraa.py 
    

    showed mraa in multiple locations, which is weird. I ended up setting my path explicitly and it works. Just remember that you need to use sudo and add the python path using "sudo visudo" as per the tutorial. You can then check by running "sudo python" and "import mraa".

    This link was also very helpful: https://communities.intel.com/message/273804

  • I had the exact same error. Installed Ubilinux and mraa as per tutorials. I copy over the pong example, it compiles fine, but throws:

    'terminate called after throwing an instance of 'int'

    when I run it, unless I run it as root or with sudo. But when I run it privileged, the OLED works fine, but the buttons do not.

    Is this block comparable with the GPIO and base blocks?

  • Any chance of these coming back in stock? I'm looking for white for my project and the 2" x 2" is too small. This flexibility of this over normal EL is amazing!

No public wish lists :(
