Wattage, which measures power, is erroneously said to measure work. |

The phrase between brackets "(the resistor, in this case)" should read "(the switch, in this case)" in order to match up with figures 2-17, 2-18 and 2-22. |

The LED in figure 2-35 appears to have the triangle pointing from negative to positive, but the text says it should point from positive to negative? |

The first horizontal wire connecting to the negative bus on the breadboard just below where we connect the power source should not have been grayed-out. It is a new wire which grounds pin 1 for the new 555 chip we are adding to the breadboard. |

Many have had trouble getting the relay to activate due to insufficient voltage. This paragraph says that the reason for using a 555 was to deliver enough voltage. However, according to Charles' Encyclopedia, Vol 2, the voltage on the output pin will be up to 1.7V less than the input. Since input is 5V, and that's what the relay needs, how can that be? In my case, I'm giving 4.86V to pin 8 and getting 3..77 volts on pin 3. Is this an error or am I missing something? |

NOTE: This also appears to affect Figure 4-83 on page 198, but i think most people will build the circuit based on Figure 4-84 on page 201. |

Printed | Page 203 3rd and 4th paragraphs that deal with buttons C D & E |
I believe the author meant buttons B C & D instead of buttons C D & E. Based on the schematics button E looks like it brings the left-hand side of the AND gate into a high state and is not involved with bringing the right-hand side of the 1st AND gate into a low state like buttons B C & D. To be clarified / confirmed. |

I know it's only used in the enhancement section, but it would be nice if the 74LS06 Inverter were listed here (perhaps with a note that it's needed only if the reader follows through with the enhancement). After all, we bought them because Charles said to on p150. |

There is no mention of what the function of Clock Input B is (74LS92 pin 1), or why it is connected to Binary input A (pin 3). I've looked at the datasheet, and it's not clear there either. I don't see this chip in either volume of Charles' Encyclopedia, but sections in Vol2 on roughly similar chips don't mention it either. |

I resisted doing experiments 34 and 25 because there was no mention in the shopping list on p.227ff, nor on this page of the programming cable. It seems dishonest to hype the inexpensive $5 picaxe and say oh by the way you need a $20 cable. |

Page 313 Figure 5-147 |
On page 311 it says that the experiment will use the same type of keypad recommended in Experiment 20. However, in figure 5-147 we see that the "common" wire in the keypad no longer applies to the asterisk and pound keys, which might confuse the reader who is attempting to build the circuit. |

lists "hom, har, and nor" as hardware suppliers. I think these might be author's placeholder words. |
