This one was too loud. I acted in self defense.

These things have only one ambition in life: to find the weak spot right between the tip of a finger and the nail and to pierce it.

Sensitivity is not adjustable. Range is a couple of meters. It needs some external intelligence to be useful as a lamp controller (off-time hysteresis). By changing the position of a 0-Ohm resistor (from L to H) it can be adjusted to re-trigger-able mode. When using a micro this is not really necessary.

Initially I had put these bridge-pads on there to select which pins are + and - and connect capacitors to them. Today I used this board with an MCP1804-SOP23-5 voltage regulator. I had everything plugged in and was in need of another GND pin. Not just the one going to the chip, bot one going to the load. Thanks to these jumpers I could use the unused pin #5 (top row in the middle) and just bridge it to GND. I need more of these little moments!
