I am seeking a skilled Device Design Engineer to create a wire-heating device for my project. The device needs to be powered by a rechargeable Lithium-Ion battery designed to heat wire to a temperature below 100°F. The wire length is between 3-5 meters. I attempted to build a similar device using a steering wheel heating wire I purchased on eBay (0.03ohm) and a 4-cell 6V battery box, but it consistently overheats. Therefore, I seek an expert who can design a reliable and efficient solution. The ideal candidate should have experience in designing small and lightweight devices. The required voltage for the Lithium-Ion battery is yet to be determined, so your expertise in selecting the appropriate battery configuration will be valuable. Note: Any suggestions or alternative approaches t...
