I am in need of an alarm clock with the following characteristics. - Military (24-hour, not AM/PM) Time, Large Digital Display Of Current Time, Slightly Smaller Digital Display Of Time Alarm Is Set For, Both Displays Clearly Visible At All Light Levels.
So far as I can tell there is no such device available commercially. The closest thing I was able to find is what Rick Scherle built for himself and discussed, up to a point, in these two posts - http://scherle.com/2010/building-the-perfect-alarm-clock-in-1200-easy-steps
Perhaps you'd like to use what Scherle has done as a starting point and follow up on your own where his discussion trails off. Or perhaps you'd prefer to blaze your own trail from the beginning. Either way, if this interests you as a project which you can sell the result of to an interested buyer, let's talk price and timeline.
Whether this is something you could develop further into a regular business, I don't know. I just know that I'm in the market for such a product.
