Allergic to Wool? Not really!

I know several people have told me in the last few weeks that they are allergic to wool.  I just stumbled across this article discussing the science behind why people really aren't allegic to wool.

They might be allergic to the chemicals used to process and clean the wool, they might be sensitive to large "scales" causing an itchy feeling, if the wool contains a lot of vegetable matter which was not processed out, the stalks of the plants might cause an itchy feeling. 

But they are probably NOT allergic to wool!

MakerFest

Yesterday, July 26,  I demonstrated two machines at the GM Employee Car Show in Warren, Michigan.  The first machine was a KH-910 with the Evil Mad Scientist AYAB hack installed.  The other was my Home Profit antique circular sock machine with a prox sensor installed to count rows.

I also took project explanation posterboards, and a table full of about 25 pairs of socks and a few sweaters and shawls. and I took too much yarn, and a couple of boxes of tools and spare needles. And a cast-iron sewing machine base with a plywood top.  And a plastic chain.

 The back of my little GMC Terrain was pretty full.    I loaded it up the night before, because I needed to arrive at 6:30 to set up and find a good parking place after unloading.  In the morning I skipped breakfast at home and visited Tim Horton's instead.  Those guys in the drive-through are SUPER FAST, and very polite.

At the MakerFest, it took me about 2 hours to set up, re-arranging the tables a few times, with lots of help from the organizers. People started showing up and asking questions  about an hour before the official start time, so I was glad to have arrived early

I had a lot of interest from several people, including three youngsters to whom I explained the concept of swatching (prototyping to makers).  The first girl (maybe about 8 years old) asked, "What is this, a doll blanket?" and I explained that different yarns had different size stitches, and to make a full-size garment I need to do some math to calculate how many stitches to put in the full sweater in order to make it fit.  She nodded her head very seriously.  She understood the concept!  She looked at all the swatches and remarked that they were very pretty.

Eventually the sun climbed higher in the sky and I had to move my display from just on the outside of the tent to inside the tent to avoid the sun, which was beating down intensely.

I explained the difference between knitting and weaving to an automotive engineer, and related it to car hoses and tires and interiors of the cars, and how the different textiles used  have different properties.  I let a beautiful woman,  who might have been a model, sit down at the CSM and knit a few rows.  She had about 10 men following her around, and they were watching and listening intently also.  She proclaimed the experience "Immensely satisfying!"  I let another engineer get "up close and personal" to the CSM to see how a knit stich is formed when the cams lift the needle butts, forcing the old stich behind the latch and the new stich in the hook when the latch closes, slipping the old stitch off the needle.

While I was demonstrating, I knitted about 7 baby beanies on the CSM (with hems!) for donation to a GM hand knitting group to pass on to the Troy Beaumont hospital  neonatal unit for preemies.

I explained the Arduino/AYAB hack about 10 times, how the KH-910 Mylar sheets are no longer available, and that model did not have an interface to the floppy drive, so no way to permanently store the patterns, and showed the electronic components I removed from the KM and the buttons used to enter a pattern one stitch at a time.

There was at least one other Arduino project there, a programmer was using a pulse sensor input to record pulse rate while listening to various types of music, in order to put a playlist of calming music together.

All in all, I think it was a very successful day.  When the photos are available I will update this post.

Monroe Seminar

I attended the Monroe Seminar, the 29th annual one.   Demonstraters Diana Sullivan of YouTube fame, Mary Anne Oger of "Knit Words" fame, and Carol Scott, who is not yet famous, but will be soon. 


Next year is going to be a REALLY BIG DEAL as the 30th annual seminar.

Thanks to Cathy Reaume and Chris for organizing this for so many years.

Monroe is more than an hour away from me.  (I don't mind travelling for this event) but I am wondering if there are other "Thumb Area machine knitters" that would be willing to join a club.

We could even sponsor an annual event, like a retreat.  But first, a club...

Resource Map of Knitting Machine - Arduino Experts


I was re-reading "Zero to Maker" by David Lang.  At the bottom of page 31, he suggests, in italics, to build a knowledge map for your subject of interest.  Since it was in italics, I thought I had better pay attention. So, here's my attempt to build a knowledge map of people who are hacking home use knitting machines.
