Solar-Powered Hat With Fan 🧢 : Perfect for Hot Summer Days! 🌬️🔥

The object I created is a hat 🧢 that collects solar energy ☀️ to power a fan and provide coolness on sunny days. On top of the hat is a photovoltaic panel that absorbs solar energy and transfers it to a solar charger. The charger stores the energy in a rechargeable battery 🔋.

When the battery has enough energy, you can press the built-in switch to activate a small motor with a fan attached. The fan spins 🌬️, generating air and keeping you cool on hot days.

It’s the perfect solution for a sunny day — providing comfort while conserving energy through clean, renewable power 🌱.

Solar Panel 2W 136x110mm

Solar Lithium Battery Charger - CN3065

Polymer Lithium Ion Battery - 3.7v 600mAh

Soft Plastic Propeller 72mm

Rocker Switch

3V-6V DC Hobby Motor

Baseball Cap

Transparent Sheet

Wires

Soldering Iron

I began the construction by assembling the electrical circuit ⚡. First, I connected the solar panel ☀️ to the battery 🔋, solar charger, and motor 🌀. (Refer to the diagram above for a clearer understanding.) I soldered one wire to the negative and one to the positive pole of both the solar panel and the motor. While soldering the wires is not necessary, I recommend doing this for extra reliability in the connections. ✅

Next, I made a hole in the baseball cap 🧢 — just large enough to fit the switch 🔘 — and carefully inserted the switch into place (see image above for reference). Once secured, I connected the switch to the circuit, as shown in the image in the previous step.

Next, I crafted a pouch 🎒 from a transparent sheet sized to fit the solar panel ☀️. I then sewed it 🪡 securely onto the top of the baseball cap (see image above). I placed the panel inside the pouch and carefully passed the wires through a small hole I made, routing them to the inside of the cap.

I mounted all the circuitry inside the cap 🧢 and secured the motor 🌀 under the bill (visor) of the cap, just like you see in the images above. Finally, I attached the fan accessory to the motor, completing the setup.

Finally, I charged the battery 🔋 using solar power ☀️ collected by the panel. Now, by simply pressing the switch 🔘, the fan starts spinning 🌀 and provides a refreshing breeze to keep you cool! 🌬️😎
