I have long wanted to make a small and comfortable, inconspicuous heat source that could use both at home and on the bus or in the office. It should be operated from any source of energy, consume very little power and long run on batteries. It should have a heat regulation. It should be very simple to make and very inexpensive cost...The result is a carbon heated belt.
For my waist took 0.9 meter (3 foot) of carbon tape 44 mm from www.carbonheater.us, a small strips of black and white fabric, one button, one meter ultra flexible cable with silicone insulation, female plug 5.5 mm with wire. The desired temperature can be determined from the table.
New! Now it works with RF remote dimmer!
