I need to sit myself down with the IEEE standards for specifications for things, and design it. I need to design both the device itself and the programming that would go on it, and then I could probably sell it to the right sort of company.
If I'm motivated.
It was a diverting few hours at work, though. I got six interviews (on the study where you're lucky to get even one, up from the five that I got a break card for yesterday) and barely noticed the time passing.
