K5CZ: I am not a big fan of paper books, I prefer electronic form, but in this case I made ??an exception and I joined this campaign.
Thanks for mentioning this. He has announced that if he raises $50,000 the book will be 40 pages rather than 25. He is only $1,700 short of reaching this goal with 70 hours to go as at the time I write this.
You can order one copy for $15 with a discount for volume orders. If you haven't placed an order this is a chance to not only get one, but help it to reach 40 pages, which will benefit everyone who has ordered one.
