We needed a clock in the living room, and being a fan of timekeeping devices in general, and a hacker / tinkerer, I set out on Google to find an LED clock kit. After about an hour of searching, I couldn't find anything that I liked under $60. Then I remembered an old Sparta alarm clock from the 80's that was tucked away in my closet (I never throw anything out.) An idea for a new case sprung into my head, and for the next few days during the down time at work, I tinkered with building a new plexiglass "case". After pulling the old alarm clock apart and tossing the unneeded parts, (the clock said "Sparta of Property" on the inside of the case. Wacky furiners.) I started on the task of soldering a crapload of wires from the control board to the display, and wiring new buttons for the hour and minute settings. I also had a few blue leds laying around, so I mounted them behind the control board for extra ambience. I drilled a bunch of holes in the 6" x 6" plexi and found some plastic standoffs for the boards. Everything I needed was "borrowed" from work except the four stainless machine screws to hold the case together.
This is actually the fourth alarm clock hack I've done. The first two were extremely realistic looking bombs. The next, and still currently in use, was a day/night switch for my bedroom alarm. At night, you could land planes with the green led display, so I took an old switch and some extra resistors and wired it in line with the display commons. (Inside that clock, it said "ProperPy of Wesclox".)
