1. What will it do?
This table will contain a heat pad that is sticks on the aluminum which will start heating the food when opening the power source. To be able to control the heating pad temperature, I will use a potentiometer to change the temperature. Also I will use a I2c screen to show the temperature on it. this will help me to know if the temperature is good to heat a specific food or not.
2. Who’s done what beforehand?
There is a Japanese invention called kotatsu which is a low, wooden table frame covered by a futon, or heavy blanket, upon which a table top sits. Underneath is a heat source, formerly a charcoal brazier but now electric. But my idea is different than this. my table will heat the food.
3. What will you design?
4. What materials and components will be used? Where will come from and How much will they cost?

RFD16N05SM9A MOSFET N-CH 50V 16A TO-252AA = 0.58 AED
Total estimated cost = 782.56 AED
5. What parts and systems will be made?
6. What processes will be used?
For the table 3D design I am going to use fusion 360 and I will use the laser cutter machine to test my design first then I will use the ShopBot cnc machine to cut the parts needed to make the table
For the circuit board I will use Eagle for the design and the Roland cnc milling machine for the milling process. and for the soldering process I will use the soldering kit.
For the potentiometer & screen cover I will design a 3D parts on fusion then I will print them using 3D printer
7. What questions need to be answered?
8. How will it be evaluated?
it will be evaluated based on its ability to heat the food to a desirable temperature.
