Home-made Air Conditioner

Hot, hot, hot!

Here is a quick way to keep stay cool with a style.

We will need:

✔ Styrofoam box

✔ Fan - more powerful, better. We used USB fan, but 12v fan would do a better job

✔ Glass bottle and bottle cutter to make a tube (We used Ephrem's Bottle Cutter)

Or you can use a plastic tube if you want. Glass looks cool :)

✔ 2 diodes, battery holder with batteries, switch

✔ Other: glue, cables, plastic sleeve, black acrylic paint, painter tape, etc.

Step 1:

First of all, we covered the painting area with painters tape, then

we painted one of the sides black.

Acrylic paint is great for this job.

Step 2:

Next, we used a bottle cutter to make a tube out of a bottle.

You can go with an ordinary tube/pipe or go with a plastic bottle.

We used glass tube as it looks cool and it's free.

After bottle was etched, we used candle and ice method to separate the glass.

Step 3:

Next, we drilled 2 holes in the tube.

We drilled in a bucket of water to make sure bottle is lubricated,

cooled and there is no glass dust in the air.

Step 4:

Then, we market a point where the tube will go, and we cut out the hole.

We also cut out a hole for the fan. We used a round weight to mark the cutting point.

It appeared to be the perfect size.

That saved as from opening the fan's cage or using any additional tools.

Step 5:

To make the tube glow, we inserted 2 led diodes in holes

and solder them to a battery with a switch.

To make sure diodes stay in place, we used hot glue.

Step 6:

Inside the box, we carved a hole for battery holder, switch and space for diodes.

Step 7:

All that was covered with a plastic sleeve,

just to make sure battery and a switch does not get wet.

Step 8:

Then, we attached a strip of paper to end of the tube. That should help us monitor/see the air flow.

We filled the cooler with 3 x 1.5 l frozen water bottles.

Step 9:

Because of the bottles and led diodes,

you have a nice blue light shining through the tube and the fan.

Final thoughts:

Does it work? Yes, it does cool a small room or you can use it in a bigger room, but make sure the air is blowing directly at you.

We used a 5v USB fan only because we could not find 12v fan locally for the price we were happy to pay.

12v fan would do a better job.

You might want to put the battery and the switch outside the box, if you are planning to turn that light on/off all the time.

    This is very nice! Might I suggest renaming this to 'Evaporative Cooler,' or 'Swamp cooler' so it can be found easier. An air conditioner, by design, cools and removes moisture from the air. An evaporative cooler is a device that cools air through the evaporation of water (and by adding moisture to the air).


    Awesome! I've seen a few versions of these, but this one has the most polished look! I really like the glass tube and led lighting. What type of bottle cutter is that? I'd like to get one.
