A bag that knows your knitting project as well as you do. The Know-It-All Knitting Bag actually has a computer chip built into it in the form of an Arduino LilyPad. The LilyPad connects to a push button and 10 LED lights–each one a stitch in a knitting-chart grid. I’ve done all the coding for you, so it’s just a matter of plugging the LilyPad into a computer and syncing it, much like you would an iPod or cell phone. For the full pattern and instructions, go visit Knitty.com and then come back to hapagirl.com for the custom-code and row-counter generator.

    Would it be possible to expand the bag downward a little? It seems like there would be more spaces on the board, you would just have to get more lights. I was just wanted to make the bag deeper and perhaps add 5 more lights to the mix. What’s your thought?

    The number of pins on the LilyPad limits the expansion capability of the circuit, at least in its current form. There’s a technique that uses sewn grids and commands that turn the lights at certain grid intersections on and off, but it’s considerably more complicated.
