First bullet item

Bullet item states "The current into the collector, divided by the cutting into the base..." Should read "The current into the collector, divided by the current into the base..."

Figure 3-3

In Figure 3-3 a photograph of a circuit is shown. I assume that the two twisted yellow cables that leave the breadboard are connected to the loudspeaker that is partially visible on the right. One of the yellow cables is connected to the 10 uF capacitor. The other yellow cable is connected to the 5VDC "+" rail, but I think it should be connected to the Ground "-" rail. Just like the schematic in Figure 3-2 shows.

figure 14-1

Circuit schematic (figure 14-1) omits the 10K pull-up resistor at tigger pin 2, pulse duration timer. The circuit does not work well without it. The pull-up resistor is shown in the breadboard photo (figure 14-3) and was mentioned in a later paragraph. Apparently the omission was overlooked in the schematic diagram.

Note from the Author or Editor:
This is correct. A revised schematic is needed.

Here is a sentence : A sensor is most easily tested with the same kind of rectangular bar magnet that you used to in- vestigate a reed switch in Experiment 28. It is incorrect claim. Bar magnet was first used in Experiment 29. There are no any magnets or reed switches in experiment 28.
