On the hardware side, there is plenty of work to do. Currently, I have done the circuits for most of the parts of the project, for example the circuit for every coil stage, lights and laser pointer is done, and now I have to put it all in a circuit with the microcontroller and Bluetooth circuitry. But before that, some final testing and prototyping have to be done on the coilgun circuit to ensure that no more MOSFETs are going to get fried.

If everything goes well in prototyping, making the complete circuit will be an easy task. Then I need to make the PCB, we are thinking between making it ourselves at home with HCl or to send it to a fabrication house like Elecrow. Once I have the PCB, some more testing will need to be done with the circuit and the 3D printed turrent before we put it on top of the tank. And that is going to be the last step, mount the turrent on top of the tank chassis and test it.

In the future and if everything goes OK to that point, I plan to add a reloading system to make the tank completely autonomous. But first we need to see how the project evolves.
