Please forgive the quality of these photos.
For the electronics of this project I referenced fellow Instructable author iideetee
Various free programs used were Eagle, and Google SketchUp.
I should warn now that I'm not big on measurements. I use them when I'm working, but you shouldn't expect to see any. This 'ible is for inspiration not mass production.
1x 4060IC 14 bit ripple counter
3x 4024ICs 7 bit ripple counter
2x 4082ICs dual input AND gates
1x 32.768 quartz crystal (salvage this from an old clock or watch. it looks like a small silver cylinder with two wires sticking out)
1x 10Mohm resistor
1x 220kohm resistor
1x 15pF capacitor
1x 2-22pF trimmer
1x "M" sized (2.1mm) DC panel mount jack
3x N.O. momentary push buttons
1x N.C. momentary push button
3x 14.7ohm resistors
17x 470ohm resistors
17x leds in whatever colors you like (Radio Shack offers a value pack of led's that are way cheaper than buying individually, but the colors are limited to red, yellow, green and amber)
I used 5x 14 pin IC sockets and one 16 pin socket because I was afraid of ruining my IC's when I soldered them
plenty of wire (I used 22 gauge)
1x printed circuit board.
thin brass stock (i believe mine was 0.032")
thin aluminum or stainless steel (again around 0.032")
I used maple for the columns because I wanted to turn them myself, and I had some left over from another project, but you can get 1" dowels made from birch at the hardware store or lumber yard.
The main housing was made mostly of yellow pine and 1/4" birch plywood. I don't have an amount because it all came from scrap I had laying around my workshop.
lots of glue and various hardware
