Lonely Binary

The TK59 at an angle: a black board with a gold border and lonely binary across the top, four right-angle pins out of its left edge labelled GND, NC, NC and SIGNAL, a tan capacitor, two small resistors and a larger black diode in the middle, ANALOG in a gold box, two round LEGO holes, and a black and a red wire running from two pads printed GND and VCC to a round black disc lying beside the board.

Piezo-Ceramic Sensor

A 22 mm piezo disc on a TinkerBlock board that needs no supply: two wires, GND and SIGNAL. A tap makes a hump on SIGNAL that rises in about a millisecond and drains in about a tenth of a second, taller for a harder tap. It senses change, not weight, and nothing on the board holds SIGNAL below 3.3 V.

Supply
Noneno VCC pin: two wires, GND and SIGNAL
A tap drains in
0.1s to a third; up in about 1 ms
Disc
Ø22mm piezo, on two leads
Held below 3.3 V
Noadd a Schottky for hard blows

Turn it over and see the two holes to wire, GND and SIGNAL, and the two NC pins that go nowhere. Pick each part: the 1 MΩ that drains the disc, the diode that stops its negative half, and the 1 kΩ and 100 nF that feed SIGNAL.

Point a phone camera at the code and this page opens there. It is the same address as the one printed on your box, so it is also what to show someone you are passing the board to.
