I spent 2 full days (morning till night), last weekend, to make a PCB board for the motors drivers for my robot. 4 DC motors and 1 stepper motor connected to a PIC32 microcontroller.
I was working on my robot yesterday, and I was connecting the battery jacks to the PCB board. The batteries are in parallel, in total of 12V 16 Amps, I connected the negative, and plugged the jack in the PCB, then I took the positive wire (to connect it to the jack), and it slipped through my fingers, and it touched the PCB board on a trace where the negative was.
It melted the traces of the PCB, and then the PIC32 chip popped, and burned, and who knows what else is burned (probably everything)...
I know all the mistakes I made, you don't have to tell me...
I am so sad I just had to let it out...
