I rode my bicycle the about 30 miles, from north of Redfield IA. to their store on Walnut St, near downtown Des Moines, and back to get whatever I needed to fix whatever radio or tv I was working on at the time.

A Schwinn cycle-truck, a std 26" rear wheel, 14" front wheel rig with a frame mounted wire basket over the front wheel for whatever. Fuggly but practical.

Re: [Emc-users] Magnetic Encoder
It is interesting how things change. Way back in early 70's there was a Hamilton Avnet office not far from my parents house. Being a kid interested in electronics I would literally ride my bike to the Hamilton Avnet office and order parts and pay cash for them. They would give me any catalog that I had an interest in. They really tried to help me out even though I probably never spent more than $20 at a time with them. (Big bucks in the early 70's). I remember having a hard time strapping all of the catalogs onto my bike rack and making it back home with my components in a little bag.I had "feet" of electronics catalogs stacked up in my room.

Re: [Emc-users] Magnetic Encoder
All, Be cautious about fitting magnetic encoders to the back of NEMA34 or larger step motors. The magnetic field in the area where the encoder is to be installed is strong enough to screw up the encoder readings. The effect shows up as noise on the position reading.
