I was motivated by my school to compete in the local bridge building competition. After designing a few bridges, I realised that i would have to find a way to consistently cut the wood dowels to a consistent lenth, which inspired me to make this ruler with 10mm increments to cut our wood dowels. It includes 21 slots for cutting the wood dowels, numbers on top to keep track of the measurements and it has a 45 degree slot at the bottom to create the perfect cut every time.

My friend asked me to create a DC motor mount for him that could store his motores and motor controler for a rc solar car that uses the sun to charge and has a small battery. His rc car would use MPPT 's to charge the battery, 2X ESP 32 development boards, one is used as a controller and the onther one is used as a recever inside the car.
