percussive sounds.\u003c\/h3\u003e\n\u003cp\u003eThis module uses the mechanics inside a relay module, it works great with this relay because it is designed very simple. The hinge that is used is using the memory of the metal to move back to its original position, because of this it bounces nicely.\u003c\/p\u003e\n\u003cp\u003eYou can solder directly to the metal to make it more heavy resulting on a longer and slower bounce (lower frequency = more base). You can bend the things soldered to the mechanical flaps that move, if you bend it up the frequency goes up, bending them in horizontal position makes lower frequencies (bend horizontal in forward position).\u003c\/p\u003e\n\u003cp\u003eThe attachements can also hit other things that can be mounted into the screw terminals of the relay board. These things can be played by hand also, a bit like a Kalimba. These terminals are not super tight so things can still move a bit.\u003c\/p\u003e\n\u003cp\u003eThe relays still work as relay, but in combination with the things that are soldered to the flaps. So it is not designed to use them as relays, i just write it here because it is possible to do something creative with this also. You can switch audio\/cv signals if you make connectors for that, but you could also switch some LED's or power a small DC motor. Dont switch mains power with it, it is not made for that.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eModule width: 75.8mm (15hp), power consumption: +160mA -10mA.
