Solution: Motorboating is a sound like the “putt-putt-putt” of a two cycle motor boat. While it may be a novel idea for a simple kit, it’s not exactly what we have in mind here. This is usually noticed at higher audio levels due to the power drawn from the power source. The power source (such as a battery) can’t quite deliver the power needed during a peak, so the voltage “sags” in response. When the voltage “sags”, it allows the power source to come back up again, along with another audio peak. Now the whole thing occurs over and over until you become annoyed enough to turn it off. While it is similar in nature to the self oscillations, it’s more reliant on power source instead of wiring. To cure this problem, try a power source with more current capacity such as alkaline batteries or even rechargeables. Otherwise the most reliable solution is a regulated DC power supply with a nominal rated current of 500mA or higher.
