This blog is on hiatus, but you can follow me on Twitter and at DIY Drones, where I’m posting daily. I’ll use this blog for occasional longer pieces that don’t fit either of those two other spots.
Notes and sources for the book
FREE was available in all digital forms--ebook, web book, and audiobook--for free shortly after the hardcover was published on July 7th. The ebook and web book were free for a limited time and limited to certain geographic regions as determined by each national publisher; the unabridged MP3 audiobook (get zip file here) will remain free forever, available in all regions.
Order the hardcover now!
