Handcrafted Dual-Temperature Controlled Incubation Box

After an entire day of immersive work, the core structure of my custom-built dual-temperature controlled incubation box has finally taken shape. Right now, the only thing left is the arrival of the custom-made door. Here’s a detailed update on the progress and the key materials used in this DIY project.

This DIY project was entirely self-planned. The frame is constructed using thickened, flame-retardant insulation boards, which provide both excellent thermal retention and structural strength. The interior lining is made from food-grade PP boards, making it waterproof, stain-resistant, and easy to clean. To achieve precise temperature control, I equipped the box with a dual-temperature control system: a mechanical thermostat on the left and a KUMETES smart digital temperature controller on the right. This dual-monitoring setup ensures reliability, and during initial empty-box testing, the temperature remained stable between 20.3°C and 20.4°C—meeting the precision requirements perfectly.

For heat dissipation and airflow, I selected two aluminum cooling modules paired with four silent fans placed on opposite sides of the box. This setup ensures smooth internal air circulation and eliminates localized temperature differences. Electrical safety was a top priority. In addition to using standard copper-core wires, I installed a compact leakage protection circuit breaker to effectively prevent short circuits and overloads. The wiring was carefully color-coded throughout, ensuring both safety and ease of future maintenance. I also added a soft LED lighting strip inside the box for convenient operation and observation.

At this point, the four core systems—temperature control, cooling, electrical, and lighting—have all been successfully tested, and the empty-box trial run performed flawlessly. Watching a pile of raw materials transform into a functional incubation box is incredibly rewarding! Now, I’m just waiting for the custom door to arrive. Once it’s installed, I’ll move on to overall sealing tests and further temperature control validation.
