This is the digital clock -- the digital striking clock -- which my father and I have been putting
together for my grandmother on my father's side of the family to use. Sorry about the
flickering in the video; that's basically an artifact of the camera. The display, if
you're looking at it in real life, doesn't seem to have that much of a flicker. Now these
4 digital displays: I'm using one display for each digit, I got these from Adafruit
Industries. The software... um, I downloaded some of their software to drive it, but I
had to modify it for my use and, um, the graphics for the digits, I made, um, I made this font
-- I designed this font myself, because I wanted numbers that look like the way numbers
appear in handwriting or in print. Now let's take a look at the back of this thing. So,
you can see the chips that drive the display. Here is the, um, this one, the round one,
that's the Chronodot, that's the really precise timekeeping device. It's also a battery backup
for when it's unplugged. And this, um, this is a sort of Arduino clone, I forget the exact
specific name for it. Oh, Boarduino, that's what it's called, it's called a Boarduino.
And a lot of this wiring -- my dad did a lot of the soldering; he's better with his hands
than I am, he's a lot better with his hands than I am. I basically did the programming.
Sight and sound! Now, as I was -- said, I basically did the programming, but he provided
this speaker, he and I worked together on the assembly, but he was the one who did this
stuff with a saw, who did the stuff with this Plexiglass and mounted everything. Yeah, it
was kind of a teamwork collaboration thing between me and my dad. Well, now we have it
ready, and we're going to give it to my grandmother today.
