Introduction: DIY Carbon Heated Beanie
I quickly feel cold, especially my head but don't like thick and bulky winter caps. So I wanted to find a simple and inexpensive design for heated beanie...
It proved to be very easy! I just put a piece of carbon fiber tape and a mobile flat battery in my beanie. Anyone will be able to do the same for an hour!
Step 1: Shopping List
3. Silver glue.
4. Blinking LED (if you like it).
5. Mobile phone battery (anyone you have but not so big for comfortable wearing).
6. Thermostat switch for the temperature you would like (only if you will power it at 12 volt)
8. An old USB cable.
Step 2: Begining...
1. Cut inseam with a scissors.
1. Cut a piece of the carbon tape. The length of the tape should be such that it may be convenient to pull a hat on your head, as it was before.
2. Connect wires with a silver glue.
Step 3: Connection...
1. Glue the click switch to the battery with a hot glue stick.
2. Solder the thermostat switch to a wire contact on the carbon tape and to click switch.
I used the thermostat to protect beanie from overheating when connected to my bike battery. You can connect carbon directly to click switch if you don't like to use a thermostat.
3. Solder battery to the switch with a piece of wire.
4. Solder led in parallel to carbon (if you need a sing your beanie is heated).
5. Solder USB (check the polarity!).
6. Test how it works.
Step 4: Assembly...
1. Unsolder one side of the carbon.
2. Put the carbon tape between beanie layers and drive it all around the circle.
3. Solder it back again.
4. Sew the seam. Leave the USB opened.
5. Charge your carbon heated beanie with a USB charger.
6. Push the button and enjoy the warm!
Step 5: Using!
I made it working in an hour but you could make it faster without thermostat and led. Maybe you want it bike powered so you don't need to solder a battery as well. Just place the carbon tape inside and connect it with a dimmer to any power source you have.
Just push the button and you will be warm in a second even in a deep cold winter. I love carbon and its heat!
