Due to the nature of the rating curve for standard automotive fuses and the average maximum short circuit current of a alkaline AA battery not being high enough for long enough period of time a 1-amp fuse should be use in place of the 3-amp fuse originally suggested in the book.

Ref Figures 2-90 and 2-91. Pressing button B does not seem to discharge the capacitor. No change in the V reading is shown, even for a split second when that button is pushed. The figures show that pushing button B connects the the two sides of the capacitor, but the positive input is still connected, with no connection to ground. Is this the correct way to discharge the capacitor? Should there be a ground connection for both sides of the capacitor similar to Figures 2-86 and 2-88? Pushing button A does what's described in the book. Note from the Author or Editor: |

Ref Figures 4-23 and 4-26. In 4-26, the value of R2 is shown along the top of the table. The value of R2 is the 10K resistor plus the value of the 100K trimpot per figure 4-23 and 2nd paragraph of Pg 156. Value of C1 is .022uF per 4-23. Given those values, shouldn't the output frequency of the speaker be ~300Hz to 2.2K? ~300Hz @ 110K (R2 = 100K trimpot + 10K resistor), and 2.2kHz @ 10K (R2 = 0K trimpot + 10K resistor). However, the left column on page 157 describes the frequency range as 300Hz to 1.2kHz in multiple places. Note from the Author or Editor: |
