So I have this customer.
They don't know the final spec of this thing they want.
They don't know if it's to be RS232 or RS485.
They can't tell me if the IR that it needs to decode is modulated or demodulated.
They can't me if the PSU is mains, 12v DC or 24v AC.
They can't tell me if it has to be CE marked.
But they do know they need it yesterday and they've sold 50 of them to their customer.
Hey ho, nothing new I don't suppose. It's always like this.
