Question by: Product code: 35-0046

Q. I'm looking to replace the uncased piezo transducer provided with the Genie Project Kit with one from which I can get more volume. Any suggestions?

A. Hi Graham. Thank you for your question. The sounder can be made louder by sticking it to a box or flat plastic sheet to act as a sounding board.The volume is mainly limited by the supply voltage to the genie which cannot exceed 5v. If you add a 500R resistor or 1K in parallel with the piezo this will make it a bit louder. To get LOUD volume you would need to use an amplifier between the gene and a bigger speaker or larger Piezo.
