Simple DIY shoe dryer

Spring and autumn are the seasons when shoes especially often get wet due to frequent rains. Shoes that are not dried can be harmful to your health by causing your feet to become hypothermic. And the shoes themselves will not last long. Whatever happens, I will show you how to make a very simple device that will allow you to avoid these problems.

The shoe dryer consists of only three components. It is not that simple, but rather the simplest. Well, I personally haven’t seen it simpler. Despite its simplicity, it has a number of significant advantages:

• - Low power consumption.
  
• - Small size. You can take it with you anywhere without any problems.
  
• - You can try batteries or accumulators as a power supply. And as a result, you can dry your shoes anywhere, say, while hiking, summer fishing, etc.

The dryer has no heating elements and dries your shoes with simple ventilation. The method is quite effective and the drying time is no longer than that of an electric heating dryer, although it all depends on the external air humidity.

What do you need for a shoe dryer?

• - Power supply 12 V (5 V).
  
• - Two 12 V coolers (fans) from the computer.

Dryer assembly

We take two fans and connect them in parallel to the power supply. We insulate with electrical tape or heat shrink tubing. And your shoe dryer is ready. We place the fans on top of the shoes, or if we insert them into the shoes. And we turn on the block to the network.


If the drying speed is not so important for you, then you can take a 5 volt power supply (phone charger). This will increase the drying time of the shoes, but will reduce the noise of the fans. Of course, it is not big, but still someone may not like it.
I would like to add that you can connect at least 10 fans to one power supply and dry 5 pairs of shoes. Enough for the whole family. And if suddenly you are all wet, and there is only one dryer, it will only take a couple of minutes to make several more dryers, unless, of course, you have all the elements at hand.
