So basically I got some small work contract with a PhD researcher. The described task is to design a battery charging circuit. They describe tasks, seems pretty usual, I sign etc. I specialize in embedded systems.
Client: Can you do a circuit that can charge a battery? We would need it soon.
Me: Sure, can you tell me the specifications? Voltage of the battery, input specs etc.
Client: Oh, I don’t have them. You are from software right? Can you do a graphical interface in Mathlab instead?
