Here are some items I found in my Twitter feed yesterday. The first two are courtesy of Bill Barnes, @ataribill.

Build a direction-finding loop antenna

This is a simple antenna that you can make from a piece of scrap coax.

Calculus Made Easy

This book, written in 1910, and brought to us via Project Gutenberg (which offers more than 57,000 free e-books), purports to make calculus more understandable. I’ve only just started wading into the book, but I think that it does make it easier, if not easy. Being the teacher that I am, I’m thinking about using this book to develop a course with a working title something like “Calculus for Makers.” That just might be doable.


This Should Work Podcast

Speaking of makers, here’s a new podcast for makers and those who run makerspaces. Episode #10 – Otherworldly Sounds, Amateur Radio, and the Ur of Maker Culture with Brian Davis pays homage to amateur radio and the place it occupies in the makersphere. Other episodes of interest to amateurs include #13 – Which 3D Printer Should You Buy? and #12 – Drew Fustini, the Open Hardware Summit Badge, and Why Make?
