My students presented their final projects on a street corner this semester: sequencers and voltage controlled oscillators.
Read on for a sequencer project layout guide (and more fun video!)
Aushra knits on the Passap
2015 was the year of the Donated Double Bed: two Passap Duomatics and a Superba S48. I had no experience with either brand, so it's taken awhile to get one working and online. There was cleaning and repair (tag-teamed with Dan, Erica, and Will), designing and building a worktable (thank you, Shae!), followed by the scavenger hunt for missing parts (props, Katrin and Richard!).
But I'm pleased to report it's finally happening! At a recent "Knitting Machine Office Hours" at Pumping Station: One, we tested settings that work with the Passap using fingering weight Tamm 3-ply Astracryl yarn. And we figured out how to knit from cones (no cake winding required)! Read on for a complete step-by-step.
I crafted this small circuit from bus wire, solder, SMD LEDs, resistors, transistor, and an ATTiny45 IC.
I programmed the Arduino to create the flicker effect and fade out, and used shellac to isolate the bus wire where necessary.
Lighting and photographing LEDs (esp surface mount!) is a challenge. Some notes for next time:
I recently found a Brother KA-8310 linker for $35 on eBay ("working condition"!). I hear these things break more than work, but for the price, I figured, why not? The linker arrived, in clean condition, with original packaging and manual. I knitted up a test swatch, followed the instructions and.... sure enough, it didn't work. Parts moved when I turned the crank, but it did not advance on the bed of my Brother 940.
Then I realized my mistake. I hadn't let Dan tinker with it first.
So, I brought it home, set the box in front of him, and said, "Wanna fix this?" He picked up a screwdriver and I grabbed my camera. (Thus began another romantic evening at home...)
