Greetings! I found something mildly awesome and figured I’d write a mini-blogpost about it. In my house, there is a tiny alarm clock.It looks exactly like this, because this is a picture of it:
It used to be my Dad’s, then it was my brother’s, and then I stole it and opened it up. I was not expecting, however, for this seemingly innocent alarm clock to have a secret. It’s been holding out on me. Check it out:
But wait! There’s more! What’s that in the upper-right corner of the board? What’s that tiny line between the two holes all about? Look closer:
I don’t know why, but I actually got really excited about this. So I hurried up and connected the two pads!
But wait a minute…
Take a careful look at the LCD display. I think I know why this feature ended up getting scrapped. The display only has enough segments to display a “1” in the leftmost digit. So what happens if I set the time higher than 19?
It goes back to 10! Well, maybe not really. Maybe it’s just displaying the rightmost part of the 2. I couldn’t be sure unless I took an in-depth look at how the clock displays the time. But that’s besides the point! I kept clicking the “Hour” button until it went all the way to “14,” and then it reverted back to 0. So while it couldn’t display the WHOLE Military time, it still did pretty good for a cheap clock!
Thinking about this makes me sad and excited at the same time. Sad, because I know that there are devices out there that have not realized their full potential. For whatever reason, what would be an awesome setting gets cut out of the final device, left to be unnoticed by 99% of people.
It also makes me excited though! There could be all kinds of hidden features in your electronics! All, I had to do was open up the case and solder a tiny wire, and I got a whole new display type! Yet another reason to open up ALL the things!
So go out there and hack those electronics!
I, for one, am going to go search my phone’s circuit board for a “Laser” function.
