Very expensive to warm at night the whole apartment when you sleep in a bed. Much better to save money on heating and warm a bed only. So I decided to make a heating blanket.
As the heating element I used the carbon tape. It looks like a thin, soft cloth and not interfere in a bed.
The carbon tape can be sewed, but instead it can be simply glued. Because of this I did it in just 1 hour!
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Put carbon tape zigzag. Zigzag shape can be any that you like.
Under the carbon tape to put iron-on hemming web tape. Gently press the carbon tape with an iron that is stuck to the fabric.
Glue the wire to the carbon tape using silver conductive wire glue. Due to the silver glue, contacts will be very thin, very small, will not interfere in a bed. These contacts can be easily and quickly done, and they will be very reliable.
Squeeze between two layers of carbon tape some silver from the syringe, insert the bare wire, squeeze glue place until the glue is completely dry.
Put strips of no-sew hem tape along the entire length of the wire. Fold the edge of the fabric and press iron.
Put contour fabric no-sew hem tape.
Cover with second piece of cloth and gently press the iron over the whole area.
Solder the plug. I connect it to the power supply from my laptop. Work is finished.
Blanket consumes about 40 watts. This power is enough not only for home beds, but also for a sleeping bag in a campaign. Then I connect the blanket to a battery 12 volts.
Blanket is a comfortable shelter, but it can also be put on a mattress under a sheet.
And you'll never cry,
Close your eyes and sleep, my angel,
Sleep, dear, rock-a-bye.
During the day I use it to cover my feet in a chair.
