    If you trying to figure out how to light these sheet, check out what I came up with: http://www.billporter.info/2013/03/31/sparkfun-fiber-optic-fabric-3d-printed-light-box/

    Requires a LED and driver you can buy here, and a little fan from Digikey. If you don’t have a 3D printer I’m willing to print out a copy for you. See the end of my post.

    If you are handy with AVR studio and a programmer, you can control up to 12 individual LEDs with this by charlieplexing. I wrote code to show you: https://github.com/madsci1016/LilyCharlieTwinkle

    Basic animation is just an expanded twinkle pattern across all 12 LEDs. You can use Vixen to easily create your own effect or even custom animations.

    I’ve been a customer for 3 years, written libraries for Sparkfun products, and spent about $2k on gear from you guys and I’d be very happy if you took the prize money and spent it on education programs instead. I’m very passionate about education (see www.sciencebrothers.org) and belive it’s a very worthy cause.

    Classes are a good start but have you considered a grant program? Let schools/programs apply for ‘grants’ in education kits, etc?

    I can second and third your dislike for the Venus GPS. A coworker and I bought a few two years ago. They were terrible, so very very bad. We both trashed them for a $100 uBlox and never looked back. Almost as good as the $$$ Novatel receivers I use at work.

  • Product DEV-10628 | about 2 years ago

    BTW, if anyone tries to use this without my library

    You do not need to edit the SdFat/Sd2PinMap.h file at all. Just include the SD CS pin (9) as the second argument in the card.init(SPI_FULL_SPEED, 9) function call.

    Or

    Use my handy dandy library to do all the work for you.

    This page is very out of date. You do not need to edit the SdFat/Sd2PinMap.h file at all. Just include the SD CS pin (9) as the second argument in the card.init(SPI_FULL_SPEED, 9) function call.

    Glad it worked for you dyynamic. Let me know if you ever have any trouble with it.

    I just finished writing an Arduino library that would make it easier to implement this project:

    Check it out.

No public wish lists :(
