Introduction: Iconic CASIO F-91W Wall/Desk Size

The Casio F-91W watch ,my favorite classic digital watch and loved by thousands around the world is becoming an iconic retro fashion.

So, why do not to Super-Size it with all the functionality ?!

Supplies:

- HMI 7" (Nextion). Product on Banggood.com

-Nextion IO adapter. Product on Amazon.es

-Arduino Mega 2560 Pro Mini (Modifying the Nextion.h Library almost any Arduino board would work too). Product on Amazon.es

-RTC Arduino. Real Time Clock. Product on Amazon.es

-USB to TTL Serial converter. Product on Amazon.es

-Buzzer. Product on Amazon.es

-3x Led Senguins. muchosleds.com

-3x TTP223 Touch Sensor. Product on Amazon.es

-2x 20mm A3 black foam. mwmaterialsworld.com

-3mm A4 Transparent acrylic.mwmaterialsworld.com

-A4 Acetate sheet. Product on Amazon.es

-3D Printed parts. Case, buttons and buckle

-2D cut parts. Straps and free loop

-Paper printed parts. Panel cover

-Wires

Step 1: Parts of the Watch

Step 2: Preparing the Parts

I got a 3D model of the watch from GrabCad.com. With my favorite 3D Software: Autodesk Maya, resized it, edited and generated the 3D parts and the outline curves for 2d engraving and cutting. Also a bitmap for the Panel Cover.

Cause the printing size of my 3D Printer (Prusa MK3) and cutting size of the CNC laser Cutter (A3) I had to split the watch Case and the Straps.

3D print, 2D cut and engrave and color print the parts.

Step 3: Getting Graphics From the 3D Model

As you can see in Photo 1, I was so lucky cause all the graphics, letters, symbols.. were on the geometry, were modeled.

Next, manually I create curves for all the graphics following the 3D model. (Photo 2)

When all the curves are done. (Photo 3) Export all them together as .dxf file.

Convert the dxf. file to bitmap (png, pdf...) I did it on a free online service.

Once you get the bitmap. (Photo 4) Edit it in your favorite painting software and get something like Photo 5.

Step 4: Touch Button

Expand a custom touch pad from the TTP223 with the 3D Button parts (button and ring), copper foil and a wire.

Stick the ring with the copper foil into the button.

Step 5: Layout Plan

Stick the 2 parts of the 3D watch case.

Stick the acrylic part to the watch case.

Plan this layout with the electronics components.

Measure distances to cut wires to size following the Electronic Schematic.

Step 6: Electronic Schematic

Use the USB to TTL Serial converter to upload the code from Nextion Editor to the HMI Display. (TX to RX and RX to TX)

Upload the Arduino Sketch to the Arduino board.

Power the Arduino with a 5v power bank or DC 5v 1A adapter. (mobile charger).

Step 7: Top Closure

Following the diagram, stick the Panel Cover, set the acetate shape and close with the Frame.

Step 8: Straps, Buckle and Free Loop

Stick the Strap parts.

Stick the Buckle parts.

Mount the Free loop.

Now stick both Straps to the Watch case.

Step 9: Back Case

I have also prepared the Back Case

Step 10: Conclusion

I am very happy with the work done. It looks so nice to me.

Hope do you like it too !

    Hi. I am not lying if I say ...less than a week. I was so lucky getting the Casio model.
    And I had all the electronic components at the workshop for another projects. 3D printer full of filament and laser cut ready. I got clear the design concept. I am good with 3D software....bla bla bla :) Very lucky cause all the things get out at first time.

    Thank you for your comment.

    Question 3 months ago on Step 2

    This is awesome! Can you post links to each of the components you used? Also, did you get the foam laser cut? Did you cut it yourself? How did you do the foam part?

    Hi there! I have an A3 (max. size) laser cut. But the straps (black 20mm foam) were too long for my laser, that´s why ( Like I said) I split both straps on 2 parts, so 4 parts. On step 7, just have to stick them together. On Step 2. Picture 2. You can see what is for cutting and what is for engraving. All files are attached.
    I will update the Instructable with the links of the components.
    Thanks for your comment!

    Thanks for this! One other question, are the parts in the STL files all the correct size? Do they need scaling up at all?

    Hi. Yes they are ready to print. Just add supports to all but the buttons.
    I exported to STL from the build plate of the slicing software.
    But I just have realize that you you'll just have to turn the buttons 180 degrees. UP/DOW

    Thanks for this! The buttons seem to have printed ok in the orientation they are in so that’s good!

    One other question, do you have the DXF file for the straps not in a perspective view? If you do could you share it as well?

    Thanks!

    The Straps_FreeLoop. dxf files is ok. Do not view here on preview. Just download and order them at your convenience.

    Wow! My Fav Watch! I've a couple in the drawer still ticking (well, very, very quietly) on the original batteries - albeit absent a decent replacement strap. So, while in awe of the time, effort and cash expended in this project, the little wire powering the replica 1. Means it is not truly portable (as the original), and 2. appears to violate electrical codes as displayed! ;)
