Solar Cooling System for Helmets

You can find a bike helmet almost anywhere like a Walmart or local convenient store.

Get your 2 9 volt batteries and positive and Negitive wires plus the fan and solder the wires to the batteries and fan and solar panels.

Of course you have to add your switch to the circuits so solder that together.

This is what it should look like it only takes about 2 hours but you can have a cool ride in the sun on your bike!

This works for safety helmets too when working on the job in the hot blazing sun every day!
