Custom PCB/circuit design Programming Delhi/NCR preferred

To be taken seriously, read the project description carefully and completely. We can handle the Mechanical design (we have a company with product design and development, mechanical, industrial engineers), we NEED someone who can do the electronics and PCB design (custom), IoT, programming etc. The system will contain, but not limited to, battery charging module, battery, heater (suggest a mechanism for heating/cooling), temperature display screen (flexible), mode selection buttons, overload and temperature protection, programming the whole thing, etc. The project is Heating/Cooling Beverage cup. When you put liquid in it, you should be able to heat and cool it ( 60 degree Celsius to 15) with display of current temperature of the fluid. Think of it like a tumbler/utensil with a removable module at the bottom (which contains all the electronics). The glass can be removed and used. The concept can be related to a cordless electric cattle but the form and purpose will be completely different (heating and cooling). The utensil (removable) can be made of steel or glass. Write (heating/cooling cup) at the beginning of your bid so we know you went through the details and only bid if you have done as follows or we will ignore the bid: Kindly let us know technical details with steps that you will adopt to execute it, please be specific as to the name of the component, processor, sensor, programming method etc.? then we can [Removed by Freelancer.com] finalize the things.
