On especially hot summer days, you can’t do without any cooling source. However, here one may encounter several difficulties: the compactness and price of such products often leaves much to be desired. Not every person will want to buy a fan for a lot of money, and those that are relatively inexpensive do not justify their purpose. Yes and there is no way to constantly carry it with you - you won’t put it in a bag, you won’t take it to the subway, and it’s better not to remember the bus at all. If a kind of "jack of all trades" jumped into you, then you can easily create such a miracle of technology do it yourself from improvised materials. How? About it further.
All that a beginner needs is a cooler, a pair of finger batteries, a holder for them, and, of course, a desire to provide himself with comfort. You can not worry about the latter, but the previous one may cause some bewilderment of readers. However, the excitement here is unnecessary, and the technology is extremely simple.
For starters, what is a cooler? It is a computer cooling system, a combination of a radiator and a fan. Also called "cooler" and device for spilling water. In any case, both options are equipped with the necessary part - a fan, which means that it suits us. You can remove the cooler (fan) from the old power supply or from the same device for pouring water (also a cooler). If you chose the first option, then along with the fan from the computer you can grab the switch, as it will not be superfluous in our business either.
It is important that the device that you want to disassemble into parts is inoperative, since removing the fan can lead to serious problems with the equipment in the future, for example, overheating of the device.
But back to our invention. The last of the parts that can cause some difficulty is the battery holder. But you can easily get it, just by letting one of the toys on finger batteries into this matter or by breaking it into the end and the already malfunctioning remote control.
The further process has few difficulties. To begin with, we collect all the details together. We insert the batteries into the holder, and this whole design into the cooler. So you not only save the much-needed space, but also protect the wires from sudden movements and disconnections. Next, connect the wires through the switch.
After that, so to speak, we “concreteize” our structure, thereby saving it from damage and removing unnecessary fragility of the product. After all, the fragility of an object on the road is an unpleasant thing, especially when you have absolutely no strength, intention or time to repair the product. In order to fix all this - take tape, or tape. It is preferable to use the second, as this is a more durable and less polluting option.
Having wrapped the entire bottom of the structure (where the battery holder should be attached to the fan), carefully cutting it off - we have a finished product.
This tool is also extremely budgetary, and if some kind of turmoil still happened and your product crashed - you can always replace it pretty quickly by making a new one according to the plan presented earlier, and taking into account all the errors handling the previous fan.
It is also recommended that when attaching the fan with adhesive tape not to touch the wires, but to leave them open, because it is there that the contact can most often go away and cause a breakdown. In this case, you can easily and fairly quickly fix this problem and continue to use the portable fan from the cooler for your pleasure.
