A Clockwork Mahogany: Making a digital clock

I don't know what time it is!!! If only I had a clock!
But not just any clock. A four foot long digital clock made out of antique mahogany wood. Guess it is time to make some sawdust!

I bought a board of reclaimed mahogany from woodcraft:
Brown Rectangle Wood Wood stain Flooring


Then I created a pattern for the led segments:
Rectangle Wood Art Font Pattern


I used a scroll saw to cut the segments out of the wood, and a plunge router to hollow out the back side of the wood:
Brown Rectangle Wood Brickwork Brick


Add some wood varnish to the top side:
Brown Rectangle Wood Sleeve Bag


I used little pieces of brass super glued into holes that I drilled into the digits to connect them:
Circuit component Wood Flooring Floor Wood stain


Here is the result:
Brown Rectangle Wood Font Brick


HH:MM:SS (okay, this picture is terrible…)
Wood Font Gas Brick Automotive exterior


It is all well and good, but kind of hard to tell time with no electronics.

Take some plexiglass:
Brown Table Wood Flooring Floor


Cut it to the shape of the LED segments (I used the scroll saw):
Wood Rectangle Flooring Floor Hardwood


Get some LEDs. I am using blue:
Musical instrument Idiophone Glass Metal Jewellery


Drill holes in the edge of the plexiglass and super glue the LEDs in the holes:
Hand Wood Gesture Thumb Nail


Sand one side of the plexiglass and paint the other side with metallic craft paint:
Wood Amber Triangle Tints and shades Flooring


Apply some voltage:
Automotive lighting Amber Automotive exterior Automotive design Gas


The two bright LEDs will be hidden behind the wood, so that the LED segment will be nice and smoothly lit.
Automotive parking light Automotive lighting Vehicle Amber Automotive tail & brake light


The whole thing will be wired up to an Arduino controller and various microchips.

I now have to build 45 more LED segments…

Updates to follow.

I have wanted to do something like this for a while too what is the overall size of the display??

Each numeric digit is 6"w x 9"h. The colons are 3"w x 9"h. This makes the wood width 42".
The brass tubing adds a total of 6 inches. The total width is 48".

I love it! Can't wait to see how this comes out. I've always wanted to do a super large 7-segment. Keep us posted, and thanks for sharing :)

Way Cool!!!

Built a digital clock from scratch- PCBs and all, back in the early 70's. Used a dedicated clock chip and 7 segment displays. Still running.

Rice paper sandwiched between two layers of plexiglass. I could have gone with smoked plastic for a more traditional digital clock. It would have been easier to read, but I am going for a "steampunk" effect here. So rice paper has been around forever and seems like the way to go…

Glue it all in. The wine really helps with precision… (No power tools were used during the stage)

I just now caught this build. This is way cool. I could get into a project like this.

How many I/O lines are required to drive the array from the Arduino? Are they multiplexed? I'd be interested in seeing your schematic. Are you writing the code yourself?

Now for some micro controllers.
The plan is to use six 74hc595 shift registers paired with six uln2003a drivers. This will mean that the Arduino will use three IO ports. Clock, Data, and Latch.
I am a software developer, and will be writing the code. The Arduino platform is pretty user friendly though and can be learned pretty quickly.
There is a nice easy small book available called "getting started with Arduino" that is geared toward non developers.
I will be posting the code in this series. I am not an electronics guy, so I will post a schematic if I can figure out a way…

Unbelievably cool mashup of old and new. Looking forward to the tech info. My buddy built a Nixie clock last year.

Chips ahoy!

Added the microchips (1) 74hc595 and (1) uln2003a per digit with 220ohm resistors on every LED. The 595s will serialize the data so that less pins are needed.
Wood Natural material Creative arts Art Glass


I finished one digit so far. I have a good amount of the wiring done on the others, but I still have to connect the LEDs to the resistors and perf board.

I wrote a test program for the Arduino and connected the first digit to it.

Here is what the one digit looks like as an '8':
Cabinetry Drawer Wood Table Chest of drawers


And here is a '5' I backed up so that the LEDs would not mess with the light sensor on this camera. (and no, there is not a 50 hour…)
Building Wood Television Curtain Comfort


And a poor attempt at a schematic:
Slope Rectangle Font Parallel Pattern

Very nice. I was an electronics engineer before I retired and I appreciate the effort that it takes to design and make something like this.
