October 6, 2018 CO get-together, Part 2
continuation of above post....
Courtney is working with a Raspberry-Pi micro-controller to do some sophisticated speed control for a sewing machine. Chris, being an engineer and John talked with him a bit, brainstorming a few ideas about how to interface to the machine.

Janey brought an example for a controller cover made from a quilted place mat. Such controller covers help to avoid scratches to a machine when the controller is placed under the harp when put away. Janey likes to sew the cover on the machine it is intended for.
John and Dorothy talked a little bit about a work stand that she is putting together to do work on machines more easily, the Thompson Mini-Walker among them. It's an extra heavy machine.
Several interesting books were brought for people to look through. We have some pictures of them, shown below. The "Coats" book defines stitches and seams used in industrial settings. The 1935 "Student Manual" shows converting treadle to a motorized machine. The Sears catalog has the Franklin Sewing machine near the front, but the motor for sewing machine is near the back. I think the "Invention of the Sewing Machine" may be a compliment to the video. (Janey can't find the link)
