Device Description

The motor from the player, with the help of a belt, the role of which is played by an elastic band for money, rotates the roller of a three-stage gearbox, which in turn rotates the take-up roller, made of two compact discs, the gap between which is filled with glue from a glue gun. A roller through a sleeve rotates a compact disc with plastic rings glued to it, which, dipping into a bath of solution, are carried opposite the fan, which blows out the bubbles. The design can be easily understood from the photo below.

Fan power supply from 12V. motor power supply from 5V. Both voltages can be taken from the molex connector of the computer power supply. 12V yellow wire, 5V red.

Gearbox rollers. made of cardboard, paper clips are used as axes.

Please note - to reduce friction and destruction of the cardboard, the rotating parts are covered with tape, which prevents the rotation surface from fraying.
