| Printed | Page 76 Figure 2-80 |
The Tactile Switch used in Fig. 2-80 and specified on page 47 has a maximum current rating of 50 mA but when discharging the 1000 uF capacitor, the current is limited only by the resistance of the wiring, contact resistance and the internal resistance of the capacitor. This results in excessive current (many Amps) through the switch, sometimes fusing the contacts. Please consider adding a current limiting resistor in series with the switch of 200 Ohms to limit the discharge current to a safe value (45 mA). This issue also shows up in Fig. 2-88 and Fig. 2-90. Alternatively, a transistor could be used to dump the charge. Comments invited. |

In the diagram in figure 16-2, pin 4 of the 555 timer chip is connected to 9v DC, but in the breadboard diagram in figure 16-3, it is connected to ground. |

Para states "If you prefer to have a sound that's all your own, you can use the circuit that I showed in Figure 4-36. Just use the output from your relay to power this circuit, and you have your own sound." I might be missing something but I think that you are then bypassing the delay built in Step 1 (p.164)? |

Para says "You only need a SPST switch for the project". I think you need a SPDT switch. |
