Most of this was just improvisation, but worked out great!
Step 1: Materials
Single Hard Drive platter
Small analog clock, or clock movement
A metal ring or two from the hard drive
Numbers, I used metal ones, you could even Sharpie some on if you wanted
Wire (you'll see why)
If you want to make on like mine, not much, Dremel with a cutting head and that's about it
I have other things pictured, but didn't end up using them for the final clock, it will be explained
Step 2: The Cap
Step 3: The Numbers
If you look close at the numbers you see tiny circles. These were scrap booking numbers. I very carefully cut them off with my dremel.
It was frustrating because they were such a flimsy and soft metal that the whole number would bend before the circle cut.
After a very very long time of gluing, looking and re-gluing, I got them where I wanted them.
Step 4: Optional Step: Hour Lines
I cut 8 small bits of wire off and lined them up like in the second picture and cut them evenly.
3rd picture shows how I hammered them, putting them n the side of the pliers and waking them until they were flat
Step 5: The Clock Movement
I dissembled it. Took off all the wires but the battery wire, like the light, alarm turn on switch, speaker, and light/snooze switch. So all I had left was the battery and the movement. Since this wasn't going to be an alarm clock, I didn't need anything else.
I quickly realized the battery tray was part of the housing. I spent half an hour trying to dremel the silly thing out, and some more time trimming it enough to fit on the back of the platter
Step 6: Gluing the Movement and Trimming the Knobs
First I glued the movement, being careful to line it up center with the hole, then trimmed the battery tray as much as possible to make it fit. Then glued that.
The knobs were to big and made the clock stick far out from the wall, so I took them both off, cut the alarm link completely, and cut the time one in about half, and trimmed the knob accordingly. The knob wouldn't stay on now, so a dab of glue to fix it.
Step 7: The Hanger Ring
So I had to build a spacer to move the ring back. I used a large juice bottle cap, Sharpied it black and cut it down, as you will see, then glued the ring to it.
Not a great picture, but you can see what I did
Step 8: Finishing Up
I put a battery in, put the hands on and set the time. There we go!
I think different hands would defiantly look nicer, but I can change those at anytime!
