Instruction
1
Glue the cardboard cylinder, the diameter of which light is greater than the external diameter of your existing computer fan, and a height about twice the diameter. He should be through. Position it vertically. Secure the fan to the lower part of the cylinder so that it blew air upwards.
2
In the middle part of the cylinder stick bright white led, also directed upwards. Connect the led with a 12-volt power source through a resistor so that the current through it was equal to the nominal, and the fan directly. Both the led and the fan plug with the correct polarity.
3
At the top of the cylinder horizontally pull a few thin wires. To each of them and attach the ribbon, cut from bright red napkins. Straighten them so they are pointing upwards.
4
Provide the cylinder with the goods, he does not move on the table from the vibration of the fan, and legs, so he was raised above the Desk and a fan can take air from the bottom.
5
Dim the lights in the room and give the device power. Ribbons, illuminated by the led, begin to sway in the air flow, giving the impression of flames.
6
If desired, the simulator can be improved. For example, to install a longer ribbon, the more powerful the fan or the light source. Important not to forget that even a faux fire can be dangerous if designed improperly. In particular, do not use this fan with metal blades which can injure the fingers, and powerful lamps, especially halogen because they are able to light the ribbon really (despite the fact that halogen lamps are used in some commercial simulators). In a fantastic performance appropriate colored artificial lights with flowers, which does not happen in a real flame without the use of dye salts, for example, green.
