| | This is my PKE/Gigameter combo. It can be set to various frequencies and has a digital LCD readout screen. It's made from a multimeter wired to a Realistic stereo microphone (like the GB Gigameter) and is mounted on an Iona shoe polisher (like the GB PKE meter). Sound causes the microphones to generate electricity, and the multimeter displays it as a numeric readout. I used an old Carbon Monoxide detector for the casing around the multimeter. |
