Homemade heated insoles
Many of us are familiar with the situation with wet or frost-free footwear. This phenomenon can lead to diseases of colds and joints. The usual warmed insoles on synthetic fur or a synthetic winterizer have effect of accumulation. When they are raw, they are not so easy to dry, and this takes time. And what if you equip them with heating? Then there is almost no need to dry them, and the feet will always be warm. Today we offer an improvised version of such miracle insoles with electric heating. Their design will help keep your feet warm for quite a while. They literally dry out in a matter of minutes, and maintaining a stable temperature will not let ordinary insoles get wet from small cracks in the shoes.We take the template of our insoles, and mark the platform on it. It should be approximately one size smaller than regular insoles. The edges of this platform insoles handle hole punch around the perimeter. This will additionally fix the heating element, and will not allow it to slide while walking.
The principle of operation of heating insolesIn his invention, the author decided to do with a heating element based on copper wire with varnished coating used for transformer windings and various inductors.Having calculated experimentally its length relative to the supplied voltage of the batteries, a heating platform was made under the main coating of conventional insoles. The insulating layer between the layers of the insole is made of hot glue. The button-switch with batteries is fastened around the shoelaces on the shoe's tab.
Necessary elements and tools for homemadeMaterials:
- Copper wire;
- Template insoles;
- Thin cardboard, paper;
- Batteries - 2 pieces;
- Plug - power supply socket;
- Wire cutter and stripper;
- Button switch;
- Universal diode;
- Wires, shrink tubers small, insulating tape.
- Soldering iron;
- Gun for hot glue;
The process of making insoles
Cutting the insoles- heating platform. For her, we need a thin thick cardboard.He must withstand walking, so it is better to choose something more resistant to abrasion. "style =" max->"
Winding up the heater windingThe intensity of the wire winding controls the amount of heating of a specific zone of the heater-insole, and you can calculate it individually. The author has marked the insole so that the maximum heat is on the toe, the middle on the heel area, and the lowest - in the middle of the foot. In accordance with the chosen scheme, we wind the coils of the heater winding by measuring the length of the wire 10 m.
We supplement the circuit with batteries with a power socket and a buttonWe connect the batteries by connecting them in parallel with the soldered contacts. The battery cases are glued to electrical tape.
Test measurementsAs practice shows, the device is capable of producing fairly good performance. For a heating element that is able to warm up shoes without harm to the foot and material, it is more than enough.
Practical tipsThe value of any invention in its long-term use, and for the heating element of the insoles, thin cardboard and paper are not a good basis . Chinese counterparts based on copper foil also do not shine with durability, breaking on the folds due to constant bends.
The whole fault is the weak base and the stickiness of the heaterThese materials can be replaced with artificial leather, felt, lavsan, etc. Instead of copper wire, use nichrome or carbon fiber for underfloor heating. Insulation of the heating element also does not hurt, and the batteries, the ability to adjust and turn off the heating can be brought closer to hands. In general, there is something to work on. These homemade products are valuable for those who like to do their own hands. They can be altered, modified and modified at their discretion, based on the principle of the device. Otherwise, every home master has a free path to creativity and his own discoveries.
