I just received the Extreme NXT 2nd edition book. I had the first one in digital format and when the second edition came out I figured I just had
to get it as I really enjoyed the first edition. I've speed read the whole thing and it looks like fun, my favorites being the servo controller and the keypad setup. However, I did have one problem. There is a PCF8591 block mentioned in the book. Well, actually two blocks. The Mindsensors one and a different one that is supposedly better. And, I can see why. The Mindsensors block is fairly complicated.
My problem is I can't find the block. It is mentioned in chapter two that NXTasy.org hosts the blocks needed in the book but as we all know, NXTasy is dead
. Xander uploaded the blocks from the repository here
but nowhere do I see mention of the PCF8591 block. I also checked both Philo and Mr. Gasperi's websites but it doesn't appear as if they have them. Does anyone have an idea of where I can get this block (or have a copy hidden in the deep, dark depths of their hard drive?)? I might eventually try to see if it's possible to use the I2C R/W blocks but I want to keep it simple for now.
Oh and do yourself a favor and get a copy of the book
. You can get it on Amazon.com for under $10 US shipped.
