If you are not versed in electronics and want to assemble a switch of garlands with a traveling wave effect, then pay attention to this homemade product.
The device is capable of switching different garlands and bulbs so that they light up and go out alternately, the effect will be very impressive. This switch does not include any radio element. Switching takes place by means of a mechanical contact.

Garland Switch Manufacturing Process
For the manufacture of the switch, it is necessary to assemble a cylindrical contact. A capacitor case is perfect for this. It needs to be sanded to expose the metal from varnish or film. The surface of the capacitor is wrapped with tape or wide electrical tape. In this case, you need to leave the bare edge by 5-10 mm.
A template is cut out of paper, according to which an insulated capacitor must be placed, and its surface is exposed. Each such open island will close a separate garland, as a result of which it can burn for a short time. The capacitor is divided along the circumference into the number of tracks equal to the number of daisies to be connected. On each of them, cut out such an island, but not opposite each other.
A pulley from the motor is glued to the capacitor.
Then the U-shaped body of the device is glued from sheet plastic.
Holes are drilled in its racks for the motor and the drum shaft.
A screw is screwed into the center of the capacitor opposite the glued pulley. You need to achieve alignment. Then the motor and drum are fixed to the bed.
From tin it is necessary to cut narrow strips of contacts.
They bend and are attached to the frame with the help of a plastic bridge. These will be rubbing contacts, each closing the circuit on its own garland.
One contact should be located on the uninsulated part of the drum.
The terminals must be soldered to the contacts.
The battery is connected to the motor through a switch.
After that, one wire from the power cable must be connected to the extreme contact constantly in contact with the drum. The wiring from the daisies should be connected to the rest of the contacts. The remaining wires are twisted together.
The drum will now rotate when the motor is started. In a short period of time, individual garlands will close and light up. This will result in alternating flickering.
