LEGO is printed as Lego or lego throughout the book

The LEGO? Group is always LEGO (all caps) and never even in their attempts in URL (though that makes no difference to the DNS servers) all capital letters. See for example http://aboutus.lego.com/en-us/lego-group

as it is a LEGO brick and LEGO Group. Anyway, it ought to be LEGO inasmuch as it ought to be IBM not Ibm ?though they are not both initialisms.

Omission on Page that leads to unknown usage for the Orage Boxes throughout the book

In the Convention Used in This Book section on pg. xi the authors clearly setup the formatting norms for the book; however, throughout the book there are additional specially formatted boxes (The orangish box with the left upper corner turned down) often these boxes have ESSENTIAL information and it seems that they ought to be mentioned in the Convention section so that you do not overlook the boxes.

Images is within the Drawbot Instructions fig. 1-1

The images at the aforementioned page contain an additional shield not in the build for the DrawBot ?specifically an Xbee Wifi Shield. This isn't as big a deal as it is an image of the Drawbot, but it isn't what the consumer will be making.

Item A. Bottom of the page

"Touch Sensor" could be anything. In fact, I believe your refrant is the Touch Sensor in the NXT 2.0 kit. This specificity is important as it is not the Touch Sensor in RCX Mindstorm kits nor is it an anonymous Touch Sensor. Small quibble, but better to be exacting!

Parts are not specific cf. letters D, E

I assume that these are the standard rims and wheels from the NXT 2.0 kit... this could be a bit more exact.

Entire listing format on the page

Formatting for a line

T 3 3M cross axles

this is a bit of an eye sore and requires more than a second look... especially when you have six lines that have the similar formatting. Perhaps something with more demarcations or the more traditional:

T.) 3M cross axle (x3)

To my eyes that is a lot easier to read. All I suggest is that the lack of punctuation makes the lines become cryptic... using just a few simple punctuation marks makes the lines much easier and less headache inducing.

Color Changing of Red item letter P in CAD file cf. fig. 1-5 though 1-57

It makes it VERY challenging to follow the rainbow coloring of the LEGO products that change within the instruction. I give for example page 6 where something that is specifically stated as RED becomes more than RED. This is completely antithetical to LEGO building and to those less careful in building obnoxious.

These "rainbowings" occur throughout the builds, as I am aware ?a simple owner of 20,000+ LEGO parts the part in question comes in RED, BLACK, and once in a while a light tan, but never Lime Green.

Images is within the Drawbot Instructions fig. 1-61

The images at the aforementioned page contain an additional shield not in the build for the DrawBot ?specifically an Xbee Wifi Shield. This could very much mislead people who do not come from an Arduino background.

Printed Page 90
code at top of page

Because the build instructions reverse the position of the two motors (from the photos on the cover and the start of chapter 4 and, obviously, the way the authors built the clock), the hands run backwards. Therefore, line 5 should be
m_pos = 3 * 2 * minute_position;
and line 9 should be
int h_pos = -2 * 5 * hour_position;

Notes 12 and 15 on page 91 should also have the signs reversed.

MANY of the Index links go to the wrong page, usually 155. I just gave one example.
