around 8-pin CMOS IC TT8486A/TT6061A

touch plate, the bulb glows dimly. On

At the third touch, the bulb is driven

use a simple copper plate of 1cm×1cm or

even the end of the lead wire. Touch plate

is coupled to the touch detector through

820pF, 2kV capacitors C1, C2, and C3 con-

nected in series. Internally IC TT6061A’s
