I've finally found a useful purpose for my buggy DNA40 device: I was sitting in a meeting at my company, discussing a typical software project that's being carried out the wrong way - design by committee, unreasonable schedule, under budget... the lot.
At some point, the project lead was arguing that, yes, we don't have specs or test plans, but we need to get coding because we're running late. I kept repeating that I won't sign the design review without them, but he was adamant he didn't have a choice and he'd forge ahead anyway.
That's when I had a genius idea: I picked up my mod, clicked on the go-go button and - lucky me - I got a bad case of scrambled screen rightaway. I showed the screen to the guy and his colleagues, and told him: "Look, this is a commercial product that's on the market right now. THIS is what people who work like you produce. I won't stand for our product doing that sort of shit. YOU WRITE YOUR SPECS AND TEST PLANS, else I'll show my little device to the program manager."
Going by the face he pulled, I think the message got across
