Cabinet Dehumidifier

The idea behind this is to make a cabinet dehumidifier that can be easily installed in any cabinet or wardrobe. You only need to use a 2.5 inch diameter hole saw to cut a hole in your cabinet, then buy a thermalelectric cooler, a 4cm cooling fan, and a power supply. For a typical power consumption of less than 10W, you can get quite good dehumidification during the wet seasons. You can use a fixed voltage power supply (5 - 12V) and there is no need to use a temperature controller to regulate the temperature unless when during the cold seasons, the cooler accumulates an ice cube. You might also need to use a pin to pierce the drainage hole once in a while to avoid blockage by dust or lint.

Some reference to buy the thermalelectric cooler with heat sink, and temperature controller:
