Tetris Houndstooth Scarf

Tetris Houndstooth Scarf 1303 977 mathgrrl

You’d think it would be easy to make a machine knitting punch card pattern based on something as simple as Tetris pieces, and I guess it is, unless you want it to be *interesting*. In this post we’ll create a two-colorable houndstooth-inspired tessellation of Tetris tetrominos that is suitable for a 24 x 48 punch card, and go from pattern to punch card, and finally to finished wearable scarf…

Punch Card Knitting Machine Patterns with OpenSCAD

Punch Card Knitting Machine Patterns with OpenSCAD 1238 928 mathgrrl

As we’ve seen in our previous posts on machine knitting, punching holes into cards can be tedious if any part of the process is manual.  Today we’ll speed up the pattern-creation process significantly by bringing OpenSCAD code to the party. With OpenSCAD we can create patterning shortcuts that allow us to quickly combine and modify basic elements like diagonals, squares, and dots to make complex designs…

We’re finally getting back to our Brother KH-881 punch card knitting machine project… and it’s time to make some punch cards! The KH-881 reads 24-stitch repeat punch cards, and uses the punched holes to determine where stitches are slipped, tucked, or knit in a differerent color, depending on the settings on the machine. Some punch cards come standard with the machine, but you can also hand-punch custom cards… // Hacktastic

Getting Started on the Brother KH-881 Punchcard Knitting Machine

Getting Started on the Brother KH-881 Punchcard Knitting Machine 640 440 mathgrrl

Just before the new year we bought a punchcard knitting machine from the 1980’s from eBay. It’s a Brother KH-881, one of the last Brother models before electronics were added to the machine. Step 1 of our plan: Figure out how to use a punchcard knitting machine! This is the first in a series of posts to catalog this journey and maybe make it slightly easier for anyone else that wants to walk the same road… // Hacktastic

Triple Check Knit

Triple Check Knit 640 480 mathgrrl

Today we’ll take a break from digital 3D design and do some good old-fashioned analog knitting. Here’s a pattern we’ve been working on recently. What is this crazy stitch, and where did it come from? We call it the Triple Check, and it’s a stitch we made up for multicolor reversible scarves that we could knit during math talks and committee meetings. Maybe it’s new, maybe it isn’t; we aren’t sure yet… // Hacktastic
