Make: Magazine, Volume 56 - Print

It doesn’t take a fully-stocked laboratory to perform biological scientific experiments. Make: Volume 56 shows you how to make electricity using everyday mud, extract DNA with a 3D-printed centrifuge, and isolate fruit DNA in your cocktails. Plus learn about one group hacking medical devices for real time diabetes data and another that’s trying to open source life-saving insulin.

Plus, more than 18 projects, including:

• Make a teeny-tiny FM transmitter spy bug
• Build a retro-style cell phone with the cutting-edge Adafruit Feather Fona
• Learn to make your own fasteners by tapping and threading.

And more!
