create humidity remover machine at home

create a simple humidity remover by placing desiccants like baking soda, silica gel, or rock salt in containers with perforations to absorb moisture from the air. For a more advanced, powered dehumidifier, you can use a Peltier chip (thermoelectric cooler) with a heatsink and a fan to condense water, which then drips into a collection container. You will also need a power source for the Peltier chip and fan, and a way to collect the water. 

Simple DIY Humidity Removers

These methods work by using materials that naturally attract and absorb water vapor from the air.

1. Baking Soda Dehumidifier
   • Materials: A small bowl, baking soda. 
   • Instructions: Fill the bowl with baking soda and place it in the area you want to dehumidify. The baking soda will absorb moisture and clump over time, indicating it needs to be replaced with fresh baking soda. 
2. Silica Gel Absorber
   • Materials: A plastic box with small holes, packets of silica gel (often found in shoe boxes). 
   • Instructions: Place the silica gel packets inside the perforated box. Position this near a moisture-prone object or in a humid area to absorb the moisture. The silica gel’s swollen packets will indicate it’s saturated. 
3. Rock Salt Dehumidifier
   • Materials: Two five-gallon buckets, rock salt. 
   • Instructions: Drill holes in one bucket. Place this bucket inside the intact bucket. Fill the top bucket with rock salt. As the salt absorbs moisture, liquid will collect in the bottom bucket. Dump the liquid and replace the salt as needed. 

DIY Thermoelectric Dehumidifier

This is a more complex, powered device that uses the Peltier effect to condense water. 

• Materials:
  • Peltier chip (thermoelectric cooler)
  • Heatsinks (one larger, one smaller)
  • Computer fan
  • Thermal compound
  • Scrap foam or cardboard for legs
  • A way to power the Peltier chip and fan (e.g., a 12V source)
  • A container to collect water
• Instructions:
  1. Attach the fan to the larger heatsink.
  2. Apply thermal compound and mount the Peltier chip onto the larger heatsink.
  3. Apply thermal compound and mount the smaller heatsink onto the other side of the Peltier chip.
  4. Create legs from foam or cardboard to elevate the device and allow space for a water collection container.
  5. Wire the fan and Peltier chip to a power source. The Peltier chip’s cold side will cause water to condense from the air.
  6. Place the device so the bottom heatsink (which will collect water) is positioned over a collection container.
