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!
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.
