When sailors are talking about their boats they often refer to ratios and numbers. That´s a tendency in human behaviour to try to generalize things to make them comparable. Of course, everybody knows that you cannot really describe apple to pears and so it´s worthless to describe a let´s say Seventies IOR-era King´s Cruiser 33 like mine to a modern day cruising yacht but we nevertheless tend to do so. The Displacement-Length-Ratio in general is a non-dimensional number. It sets into relation the displacement of a boat (expressed in pounds) to the length of her waterline (in feet). So, in general, this ratio is looking for the relation between the (heavy?) volume of water being pushed aside by a boat´s hull and the length (and therefore speed potential see for my article Hull speed vs. Froude number here) of her hull. Sounds fair enough?

ABOUT HOW THINGS WORK AT MY ONLINE CLASSES: 1. Each week-end you will receive the brief in a secret Facebook group: a challenge that you will have to work on until next Friday. 2. Each Friday you will have to send me your sketches via email here: firstname.lastname@example.org 3. Stay tuned on 2 things: your email and the secret Facebook group - where each Sunday I will post a new challenge + a lot of tips, links, inspiring posts, trends and theoretic knowledge. 4. You will receive by email a personal feed-back on your drawings and tips on how to improve 5. Then, we repeat: Each week-end you will receive a new brief, have time until next Friday to sketch, then send me your sketches for feed-backs and then wait for another brief. 6. At the end of the 3 months course you will receive a diploma that will attest the fact that you did all the 12 challenges and you took the online course with me.

Dedicated integrated circuits have dramatically simplified stepper motor driving. To apply these ICs, designers need little specific knowledge of motor driving techniques, but an understanding of the basics helps in finding the best solution. This note explains the basics of stepper motor driving and describes the drive techniques used today.
