I’ve released a new version of the textbook Applied Electronics for Bioengineers, on the LeanPub website: https://leanpub.com/applied_electronics_for_bioengineers and sent the students registered for the course a coupon to get their free copy.  People who have previously bought the book (even if for $0 with a coupon) were also informed of the release, so that they could pick up a new copy.

This version is 481 pages including 38 chapters, preface, appendices, and index.  There are 10 tables and 199 figures (239 distinct images, since some figures have multiple subfigures).  I added a lot of new tutorial material, fixed some errors (including some serious ones), added more exercises, and modified the labs to use the Analog Discovery 2 USB oscilloscopes rather than the expensive bench equipment we used to use.  The book is not “done”—I still have over 50 to-do notes in the margins, but I believe it is significantly improved over last year.  Improvements would be faster if students would tell me when they find errors or confusing writing, but they rarely do, and I have to guess what needs fixing from mistakes they make weeks later.

The use of the Analog Discovery 2 enabled me to offer a larger course this year—I managed to equip a 25-station lab for 50 students for under $10,000—less than the cost of a single station in the old lab. Because the space I’m using for the two 50-student sections is used as a classroom by other courses, I need to wheel everything in on a cart 20 minutes before labs start and clean it up and pack it away after the labs.

I still have a little work to do before next quarter starts:

  • recording the serial numbers and setting the names of the 25 Analog Discovery 2 units.
  • checking the 25 soldering stations and tinning the tips.
  • soldering 25 pressure sensors onto breakout boards.
  • packing everything into tubs that I can wheel to the other building on the cart.
  • cleaning up the electrode holders that did not get cut cleanly by the laser cutter.
  • getting reimbursed for over $3000 worth of parts and tools that I ordered for the students (UCSC can’t buy from AliExpress, and US vendors were over 3 times the price).

But I think that tomorrow I’ll take a break—maybe even see if I can get anything working on the robot I didn’t finish for the mechatronics course.
