Intro: Desk Air Cooler Made by an Ice Cream Cup

Since the summer is hot, I have decided to make this little DIY desk air cooler. I hope you like it and write in the comments what you think of this "project" C:

Step 1: Draw the Outline and Cut Out the Lid

First of you need a compasses and a fine-tipped marker to draw the outline, trace the line near the edge because if the circle is too small the air can not enter in the cup. Cut the outline with a cutter and go to the next step

Step 2: Assembly the Lid

Once the fan holder has been printed glue it on the lid with hot glue gun. To give more resistance to the support also glue it on the back

Step 3: Connect the Fan to a Male USB a Connector

To connect the fan to a power supply (like a power bank, a pc, or on a phone charger) you need a USB A (male) cable. I have get the cable from an adapter that I not use. To find the right cables:

  1. Cut the cable
  2. Inside the cable there are usually 4 cables, cut the green and the white cable to have only the GND and VCC
  3. Peel the end of the two cables

On the fan:

  1. Cut the white connector and separate the two wires
  2. Peel the end of the two cables

To connect the wires solder the GND cable form USB with the GND fan cable, and do the same with the VCC

To avoid interferences apply heat shrink tubing around the wires

Step 4: The Cup

Trace some squares around the top of the cup and cut it (i have used my soldering iron because the cutter broke the cup). At last put some water inside the cup (not over the middle) and put the cup in the freezer for about 24 hours. When the water is frozen take the cup out the freezer and put the lid on it. Connect the fan to a power source (i have used a powerbank) and the air will begin to exit from the holes, a little bit fresher than before. The ice remains frozen for about 1 hour of use, you can use this for 1 hour.

    Question 6 weeks ago on Step 2

    I would have to stop right here. I have no idea what is going on, and I don't know what tools and supplies we are using at this point.
