I was inspired by Kristie's blog post here: http://diynmbcprops.blogspot.com/2011/09/halloween-count-down-clock-prop.html and decided to try my hand at making my own NBC countdown clock.

Front and back cut from 1/4" hardboard with a jigsaw.
I made this 18" wide, but in retrospect I wish I'd gone about 2 inches wider

Plexi hot-glued in-place

Old hard drive magnets routed into the corners of the back hardboard.
This was not the most effective way to attach the back. For the back of the clock face I just screwed it together.

Countersunk screws for the magnets to attract

Two cheap puck lamps disassembled and both leds hot-glued to back panel

Face plexiglass cut. Rear sprayed white. Front painted by hand with black acrylic

Face edges silhouetted with flat black.
Clock hands cut from scrap plexi and sprayed flat black. Attached with a nut & bolt.
I used two separate power supplies so I don't have to display the whole prop (i.e. just putting the base on a table instead of hanging it all), but I could have easily run all the leds off one adapter.
