A clock that takes the shape of the Assassin's Creed Origins logo.
Made of wood and plexiglass, it incorporates a simple needle clock mechanism, and a ring NeoPixel 24 LED RGB that fills the rhythm of seconds. The LEDs are driven by an Arduino Nano. The logo is painted in antique gold to stick with the universe of the game: ancient Egypt. The clock can be wall mounted or placed on a plexiglass stand.
I made it to give a fan of Assassin's Creed !

Step 1: Preparation
I printed the Assassin's Creed logo on 2 sheets in A3 format, it is printed in mirror to cut the logo upside down and not to damage the wood on takeoff.
I glued them on a wooden board with spray glue to use them as a template.
Step 2: Cutting Wood
I used a Dremel 3000 with its router accessory (335) to cut the board according to the template.
I was a little afraid that it would be hard to stay upright but it follows rather well the line, it is rather stable. The work area is clear and does not produce too much sawdust.
For the internal parts, the tool allows to descend directly, there is not even need to make a hole before
Step 3: Plexi Cutting
Then I stuck the wooden logo on the plexiglass using double-sided tape, I installed the copy ring on the router.
I use the smallest ring because I want my plastic piece to be slightly larger than my wooden piece
I cut the plexi following the sides of the wood.
I used the same cutter to cut the plastic and the result is pretty good, I do not have any splinters. It's very simple to make, just follow the edges of the wooden piece
Step 4: Paint
I started by putting a layer of white paint to the bomb to remove wood defects.
I then applied 2 layers of antique gold paint, to stay in the game's disgust
Step 5: LED Ring Integration
I dug the plexi with 2 hole saws to fit the NeoPixel ring in the thickness of the plexi.
I added a black adhesive to hide the ring and that its lighting is diffused on the sides of the plexiglass.
I glued it to the glue gun and then installed the clock mechanism.
Step 6: Assembly
I glued and screwed the wooden logo on the plexiglas logo.
I added "feet" so that the clock stays upright when it is attached to the wall.
I cut piece of medium (MDF) which will allow to attach the clock to the wall without leaning. I pierce the plexi to be able to pass screws and I mill the holes to fit the screw head.
Step 8: Electronic
Since the LED ring already contains electronic components, the diagram is very simple!
There are just 3 soldering wires between the ring and the Arduino Nano. There is no need for additional components
For the code, I used the library Adafruit_NeoPixel which facilitates a lot of work!
I wanted to reproduce the movement of the second hand by lighting the ring in 60 seconds but for the tests I accelerated it and every turn there is a random color change.
A simple USB cable and a phone charger are enough to power the circuit.
Step 9: Stand
I created a mounting bracket with 2 drops of plexi connected by tape.
We can choose between placing the clock on a table or attach it to the wall.
Step 10: Done!
It's over ! This gift pleased my brother in law!
