Description: Are you sick of the summer heat? Tired of sweating in front of the computer :)? A homemade USB / CD fan from your CD / DVD will help you! If suddenly you do not play video from homemade from a CD / DVD disc, then here is a short production instruction do it yourself:
Materials: Two CD / DVD discs, a cork from a bottle of wine, a cardboard cylinder (from toilet paper or from a roll of wallpaper), a motor (from a CD drive or printer) and a USB cable.
Instruments: Scissors, awl, glue, candle.
Fan assembly: We divide the disk into 8 equal sectors-blades, cut it to the transparent part of the disk, heat the base of the blade on the candle and rotate about 30 degrees. We adjust the cork from the bottle of wine to the diameter of the disk, so that it fits tightly into the hole. Precisely in the middle of the cork we make a hole with an awl and insert it into the disk. Next, you need to prepare the motor - we fix it on a cardboard cylinder (the height of the cylinder you need to choose a larger radius of the disk) with glue (it is better to use a glue gun). We attach the cylinder with the motor to the second CD / DVD disc (it serves as the basis of a homemade fan) with glue.
Now we need to power the motor - we take an unnecessary USB cable, we strip one end, we leave only black and red wiring. We connect them to email. to the motor.
With the last action, we put the fan on the motor axis.
Homemade USB fan is ready!
Tip: For convenience, a break can be put on the switch.
